A great many readers this month reported receiving alerts that their Social Security Number, name, address and other personal information were exposed in a breach at a little-known but aptly-named consumer data broker called NationalPublicData.com. This post examines what we know about a breach that has exposed hundreds of millions of consumer records. We’ll also take a closer look at the data broker that got hacked — a background check company founded by an actor and retired sheriff’s deputy from Florida.

On July 21, 2024, denizens of the cybercrime community Breachforums released more than 4 terabytes of data they claimed was stolen from nationalpublicdata.com, a Florida-based company that collects data on consumers and processes background checks.

The breach tracking service HaveIBeenPwned.com and the cybercrime-focused Twitter account vx-underground both concluded the leak is the same information first put up for sale in April 2024 by a prolific cybercriminal who goes by the name “USDoD.”

On April 7, USDoD posted a sales thread on Breachforums for four terabytes of data — 2.9 billion rows of records — they claimed was taken from nationalpublicdata.com. The snippets of stolen data that USDoD offered as teasers showed rows of names, addresses, phone numbers, and Social Security Numbers (SSNs). Their asking price? $3.5 million.

Many media outlets mistakenly reported that the National Public data breach affects 2.9 billion people (that figure actually refers to the number of rows in the leaked data sets). HaveIBeenOwned.com’s Troy Hunt analyzed the leaked data and found it is a somewhat disparate collection of consumer and business records, including the real names, addresses, phone numbers and SSNs of millions of Americans (both living and deceased), and 70 million rows from a database of U.S. criminal records.

Hunt said he found 137 million unique email addresses in the leaked data, but stressed that there were no email addresses in the files containing SSN records.

“If you find yourself in this data breach via HaveIBeenPwned.com, there’s no evidence your SSN was leaked, and if you’re in the same boat as me, the data next to your record may not even be correct.”

Nationalpublicdata.com publicly acknowledged a breach in a statement on Aug. 12, saying “there appears to have been a data security incident that may have involved some of your personal information. The incident appears to have involved a third-party bad actor that was trying to hack into data in late December 2023, with potential leaks of certain data in April 2024 and summer 2024.”

The company said the information “suspected of being breached” contained name, email address, phone number, social security number, and mailing address(es).

“We cooperated with law enforcement and governmental investigators and conducted a review of the potentially affected records and will try to notify you if there are further significant developments applicable to you,” the statement continues. “We have also implemented additional security measures in efforts to prevent the reoccurrence of such a breach and to protect our systems.”

Hunt’s analysis didn’t say how many unique SSNs were included in the leaked data. But according to researchers at Atlas Data Privacy Corp., there are 272 million unique SSNs in the entire records set.

Atlas found most records have a name, SSN, and home address, and that approximately 26 percent of those records included a phone number. Atlas said they verified 5,000 addresses and phone numbers, and found the records pertain to people born before Jan. 1, 2002 (with very few exceptions).

If there is a tiny silver lining to the breach it is this: Atlas discovered that many of the records related to people who are now almost certainly deceased. They found the average age of the consumer in these records is 70, and fully two million records are related to people whose date of birth would make them more than 120 years old today.

TWISTED HISTORY

Where did National Public Data get its consumer data? The company’s website doesn’t say, but it is operated by an entity in Coral Springs, Fla. called Jerico Pictures Inc. The website for Jerico Pictures is not currently responding. However, cached versions of it at archive.org show it is a film studio with offices in Los Angeles and South Florida.

The Florida Secretary of State says Jerico Pictures is owned by Salvatore (Sal) Verini Jr., a retired deputy with the Broward County Sheriff’s office. The Secretary of State also says Mr. Verini is or was a founder of several other Florida companies, including National Criminal Data LLC, Twisted History LLC, Shadowglade LLC and Trinity Entertainment Inc., among others.

Mr. Verini did not respond to multiple requests for comment. Cached copies of Mr. Verini’s vanity domain salvatoreverini.com recount his experience in acting (e.g. a role in a 1980s detective drama with Burt Reynolds) and more recently producing dramas and documentaries for several streaming channels.

Sal Verini’s profile page at imdb.com.

Pivoting on the email address used to register that vanity domain, DomainTools.com finds several other domains whose history offers a clearer picture of the types of data sources relied upon by National Public Data.

One of those domains is recordscheck.net (formerly recordscheck.info), which advertises “instant background checks, SSN traces, employees screening and more.” Another now-defunct business tied to Mr. Verini’s email — publicrecordsunlimited.com — said it obtained consumer data from a variety of sources, including: birth, marriage and death records; voting records; professional licenses; state and federal criminal records.

The homepage for publicrecordsunlimited.com, per archive.org circa 2017.

It remains unclear how thieves originally obtained these records from National Public Data. KrebsOnSecurity sought comment from USDoD, who is perhaps best known for hacking into Infragard, an FBI program that facilitates information sharing about cyber and physical threats with vetted people in the private sector.

USDoD said they indeed sold the same data set that was leaked on Breachforums this past month, but that the person who leaked the data did not obtain it from them. USDoD said the data stolen from National Public Data had traded hands several times since it was initially stolen in December 2023.

“The database has been floating around for a while,” USDoD said. “I was not the first one to get it.”

USDoD said the person who originally stole the data from NPD was a hacker who goes by the handle SXUL. That user appears to have deleted their Telegram account several days ago, presumably in response to intense media coverage of the breach.

ANALYSIS

Data brokers like National Public Data typically get their information by scouring federal, state and local government records. Those government files include voting registries, property filings, marriage certificates, motor vehicle records, criminal records, court documents, death records, professional licenses, bankruptcy filings, and more.

Americans may believe they have the right to opt out of having these records collected and sold to anyone. But experts say these underlying sources of information — the above-mentioned “public” records — are carved out from every single state consumer privacy law. This includes California’s privacy regime, which is often held up as the national leader in state privacy regulations.

You see, here in America, virtually anyone can become a consumer data broker. And with few exceptions, there aren’t any special requirements for brokers to show that they actually care about protecting the data they collect, store, repackage and sell so freely.

In February 2023, PeopleConnect, the owners of the background search services TruthFinder and Instant Checkmate, acknowledged a breach affecting 20 million customers who paid the data brokers to run background checks. The data exposed included email addresses, hashed passwords, first and last names, and phone numbers.

In 2019, malicious hackers stole data on more than 1.5 billion people from People Data Labs, a San Francisco data broker whose people-search services linked hundreds of millions of email addresses, LinkedIn and Facebook profiles and more than 200 million valid cell phone numbers.

These data brokers are the digital equivalent of massive oil tankers wandering the coast without GPS or an anchor, because when they get hacked, the effect is very much akin to the ecological and economic fallout from a giant oil spill.

It’s an apt analogy because the dissemination of so much personal data all at once has ripple effects for months and years to come, as this information invariably feeds into a vast underground ocean of scammers who are already equipped and staffed to commit identity theft and account takeovers at scale.

It’s also apt because much like with real-life oil spills, the cleanup costs and effort from data spills — even just vast collections of technically “public” documents like the NPD corpus — can be enormous, and most of the costs associated with that fall to consumers, directly or indirectly.

WHAT SHOULD YOU DO?

Should you worry that your SSN and other personal data might be exposed in this breach? That isn’t necessary for people who’ve been following the advice here for years, which is to freeze one’s credit file at each of the major consumer reporting bureaus. Having a freeze on your files makes it much harder for identity thieves to create new accounts in your name, and it limits who can view your credit information.

The main reason I recommend the freeze is that all of the information ID thieves need to assume your identity is now broadly available from multiple sources, thanks to the multiplicity of data breaches we’ve seen involving SSN data and other key static data points about people.

But beyond that, there are numerous cybercriminal services that offer detailed background checks on consumers, including full SSNs. These services are powered by compromised accounts at data brokers that cater to private investigators and law enforcement officials, and some are now fully automated via Telegram instant message bots. Meaning, if you’re an American who hasn’t frozen their credit files and you haven’t yet experienced some form of new account fraud, the ID thieves probably just haven’t gotten around to you yet.

All Americans are also entitled to obtain a free copy of their credit report weekly from each of the three major credit bureaus, through the website annualcreditreport.com. It used to be that consumers were allowed one free report from each of the bureaus annually, but in October 2023 the Federal Trade Commission announced the bureaus had permanently extended a program that lets you check your credit report once a week for free. If you haven’t done this in a while, now would be an excellent time to order your files.

Either way, review the reports and dispute any errors you may find. Identity theft and new account fraud is not a problem that gets easier to solve by letting it fester.

Mr. Verini probably didn’t respond to requests for comment because his company is now the subject of a class-action lawsuit (NB: the lawsuit also erroneously claims 3 billion people were affected). These lawsuits are practically inevitable now after a major breach, but they also have the unfortunate tendency to let regulators and lawmakers off the hook.

Almost every time there’s a major breach of SSN data, Americans are offered credit monitoring services. Most of the time, those services come from one of the three major consumer credit bureaus, the same companies that profit by compiling and selling incredibly detailed dossiers on consumers’ financial lives. The same companies that use dark patterns to trick people into paying for “credit lock” services that achieve a similar result as a freeze but still let the bureaus sell your data to their partners.

But class-actions alone will not drive us toward a national conversation about what needs to change. Americans currently have very few rights to opt out of the personal and financial surveillance, data collection and sale that is pervasive in today’s tech-based economy.

The breach at National Public Data may not be the worst data breach ever. But it does present yet another opportunity for this country’s leaders to acknowledge that the SSN has completely failed as a measure of authentication or authorization. It was never a good idea to use as an authenticator to begin with, and it is certainly no longer suitable for this purpose.

The truth is that these data brokers will continue to proliferate and thrive (and get hacked and relieved of their data) until Congress begins to realize it’s time for some consumer privacy and data protection laws that are relevant to life in the 21st century.

Update, Aug. 16, 8:00 a.m. ET: Corrected the story to note that consumers can now obtain a free credit report from each of the three consumer reporting bureaus weekly, instead of just annually.

Microsoft today released updates to fix at least 90 security vulnerabilities in Windows and related software, including a whopping six zero-day flaws that are already being actively exploited by attackers.

This month’s bundle of update joy from Redmond includes patches for security holes in Office, .NET, Visual Studio, Azure, Co-Pilot, Microsoft Dynamics, Teams, Secure Boot, and of course Windows itself. Of the six zero-day weaknesses Microsoft addressed this month, half are local privilege escalation vulnerabilities — meaning they are primarily useful for attackers when combined with other flaws or access.

CVE-2024-38106, CVE-2024-38107 and CVE-2024-38193 all allow an attacker to gain SYSTEM level privileges on a vulnerable machine, although the vulnerabilities reside in different parts of the Windows operating system.

Microsoft’s advisories include little information about the last two privilege escalation flaws, other than to note they are being actively exploited. Microsoft says CVE-2024-38106 exists in the Windows Kernel and is being actively exploited, but that it has a high “attack complexity,” meaning it can be tricky for malware or miscreants to exploit reliably.

“Microsoft lists exploit complexity as high due to the attacker needing to win a race condition,” Trend Micro’s ZeroDay Initiative (ZDI) noted. “However, some races are easier to run than others. It’s times like this where the CVSS can be misleading. Race conditions do lead to complexity high in the CVSS score, but with attacks in the wild, it’s clear this bug is readily exploitable.”

Another zero-day this month is CVE-2024-38178, a remote code execution flaw that exists when the built-in Windows Edge browser is operating in “Internet Explorer Mode.” IE mode is not on by default in Edge, but it can be enabled to work with older websites or applications that aren’t supported by modern Chromium-based browsers.

“While this is not the default mode for most users, this exploit being actively exploited suggests that there are occasions in which the attacker can set this or has identified an organization (or user) that has this configuration,” wrote Kev Breen, senior director of threat research at Immersive Labs.

CVE-2024-38213 is a zero-day flaw that allows malware to bypass the “Mark of the Web,” a security feature in Windows that marks files downloaded from the Internet as untrusted (this Windows Smartscreen feature is responsible for the “Windows protected your PC” popup that appears when opening files downloaded from the Web).

“This vulnerability is not exploitable on its own and is typically seen as part of an exploit chain, for example, modifying a malicious document or exe file to include this bypass before sending the file via email or distributing on compromised websites,” Breen said.

The final zero-day this month is CVE-2024-38189, a remote code execution flaw in Microsoft Project. However, Microsoft and multiple security firms point out that this vulnerability only works on customers who have already disabled notifications about the security risks of running VBA Macros in Microsoft Project (not the best idea, as malware has a long history of hiding within malicious Office Macros).

Separately, Adobe today released 11 security bulletins addressing at least 71 security vulnerabilities across a range of products, including Adobe Illustrator, Dimension, Photoshop, InDesign, Acrobat and Reader, Bridge, Substance 3D Stager, Commerce, InCopy, and Substance 3D Sampler/Substance 3D Designer. Adobe says it is not aware of active exploitation against any of the flaws it fixed this week.

It’s a good idea for Windows users to stay current with security updates from Microsoft, which can quickly pile up otherwise. That doesn’t mean you have to install them on Patch Tuesday each month. Indeed, waiting a day or three before updating is a sane response, given that sometimes updates go awry and usually within a few days Microsoft has fixed any issues with its patches. It’s also smart to back up your data and/or image your Windows drive before applying new updates.

For a more detailed breakdown of the individual flaws addressed by Microsoft today, check out the SANS Internet Storm Center’s list. For those admins responsible for maintaining larger Windows environments, it pays to keep an eye on Askwoody.com, which frequently points out when specific Microsoft updates are creating problems for a number of users.

A partial selfie posted by Puchmade Dev to his Twitter account. Yes, that is a functioning handheld card skimming device, encrusted in diamonds. Underneath that are more medallions, including a diamond-studded bitcoin and payment card.

In January, KrebsOnSecurity wrote about rapper Punchmade Dev, whose music videos sing the praises of a cybercrime lifestyle. That story showed how Punchmade’s social media profiles promoted Punchmade-themed online stores selling bank account and payment card data. The subject of that piece, a 22-year-old Kentucky man, is now brazenly suing his financial institution after it blocked a $75,000 wire transfer and froze his account, citing an active law enforcement investigation.

With memorable hits such as “Internet Swiping” and “Million Dollar Criminal” earning millions of views, Punchmade Dev has leveraged his considerable following to peddle tutorials on how to commit financial crimes online. But until recently, there wasn’t much to support a conclusion that Punchmade was actually doing the cybercrime things he promotes in his songs.

That changed earlier this year when KrebsOnSecurity showed how Punchmade’s social media handles were promoting Punchmade e-commerce shops online that sold access to Cashapp and PayPal accounts with balances, software for printing checks, as well as personal and financial data on Americans.

Punchmade Dev’s previous online shop (now defunct). His Telegram channel has more than 75,000 followers.

The January story traced Punchmade’s various online properties to a 22-year-old Devon Turner from Lexington, Ky. Reached via his profile on X/Twitter, Punchmade Dev said they were not affiliated with the lawsuit filed by Turner [Punchmade’s X account provided this denial even though it has still not responded to requests for comment from the first story about him in January]. Meanwhile, Mr. Turner has declined multiple requests to comment for this story.

On June 26, Turner filed a pro se lawsuit against PNC Bank, alleging “unlawful discriminatory and tortuous action” after he was denied a wire transfer in the amount of $75,000. PNC Bank did not respond to a request for comment.

Turner’s complaint states that a follow-up call to his bank revealed the account had been closed due to “suspicious activity,” and that he was no longer welcome to patronize PNC Bank.

“The Plaintiff is a very successful African-American business owner, who has generated millions of dollars with his businesses, has hired 30 plus people to work for his businesses,” Turner wrote.

As reported in January, among Turner’s businesses is a Lexington entity called OBN Group LLC (assumed name Punchmade LLC). Business incorporation documents from the Kentucky Secretary of State show he also ran a record label called DevTakeFlightBeats Inc.

Turner’s lawsuit alleges that bank staff made disparaging remarks about him, suggesting the account was canceled because it would be unusual for a person like him to have that kind of money.

A snippet from Turner’s lawsuit vs. PNC.

Incredibly, Turner acknowledges that PNC told him his account was flagged for attention from law enforcement officials.

“The PNC Bank customer service representative also explained that there was a note on the account that law enforcement would be contacted at some point in time,” the lawsuit reads.

“The Plaintiff, who was not worried at all about law enforcement being involved because nothing illegal occurred, informed the PNC Bank representative that this was one big mistake and asked him what his options were,” the complaint states.

Turner’s lawsuit said PNC told him they would put a note on his account allowing him to withdraw the funds from any branch, but that when he visited a PNC branch and asked to withdraw the entire amount in his account — $500,000 — PNC refused, saying the money had been seized.

“Ultimately, PNC bank not only refused his request to release his funds but informed him that his funds would be seized indefinitely as [sic] PNC Bank,” Turner lawsuit recounts.

The Punchmade shops selling financial data that were profiled in the January story are long gone, but Punchmade’s Instagram account now promotes punchmade[.]cc, which behaves and looks the same as his older shop.

Punchmade’s current shop, which DomainTools says was registered to a Lexington, Ky. phone number used by accounts under the name of Devon Turner at multiple online retailers.

The breach tracking service Constella Intelligence finds the email address associated with Turner’s enterprise OBN Group LLC — obndevpayments@gmail.com — was used by a Devon Turner from Lexington to purchase software online. That record includes the Lexington, Ky. mobile phone number 859-963-6243, which Constella also finds was used to register accounts for Devon Turner at the retailer Neiman Marcus, and at the home decor and fashion site poshmark.com.

A search on this phone number at DomainTools shows it is associated with two domain names since 2021. The first is the aforementioned punchmade[.]cc. The other is foreverpunchmade[.]com, which is registered to a Devon Turner in Lexington, Ky. A copy of this site at archive.org indicates it once sold Punchmade Dev-branded t-shirts and other merchandise.

Mr. Turner included his contact information at the bottom of his lawsuit. What phone number did he leave? Would you believe 859-963-6243?

The closing section of Mr. Turner’s complaint includes a phone number that was used to register a popular online fraud shop named after Punchmade.

Is Punchmade Dev a big-time cybercriminal enabler, as his public personna would have us believe? Or is he some two-bit nitwit who has spent so much on custom medallions that he can’t afford a lawyer? It’s hard to tell.

But he definitively has a broad reach: His Instagram account has ~860k followers, and his Telegram channel has more than 75,000 subscribers, all no doubt seeking that sweet “C@sh App sauce,” which apparently has something to do with moving cryptocurrencies through Cash App in a way that financially rewards people able and willing to open up new accounts.

It’s incredibly ironic that Punchmade sells tutorials on how to have great “opsec,” a reference to “operational security,” which in the cybercriminal context means the ability to successfully separate one’s cybercriminal identity from one’s real-life identity: This guy can’t even register a domain name anonymously.

A copy of Turner’s complaint is available here (PDF).

A ransomware group called Dark Angels made headlines this past week when it was revealed the crime group recently received a record $75 million data ransom payment from a Fortune 50 company. Security experts say the Dark Angels have been around since 2021, but the group doesn’t get much press because they work alone and maintain a low profile, picking one target at a time and favoring mass data theft over disrupting the victim’s operations.

Image: Shutterstock.

Security firm Zscaler ThreatLabz this month ranked Dark Angels as the top ransomware threat for 2024, noting that in early 2024 a victim paid the ransomware group $75 million — higher than any previously recorded ransom payment. ThreatLabz found Dark Angels has conducted some of the largest ransomware attacks to date, and yet little is known about the group.

Brett Stone-Gross, senior director of threat intelligence at ThreatLabz, said Dark Angels operate using an entirely different playbook than most other ransomware groups. For starters, he said, Dark Angels does not employ the typical ransomware affiliate model, which relies on hackers-for-hire to install malicious software that locks up infected systems.

“They really don’t want to be in the headlines or cause business disruptions,” Stone-Gross said. “They’re about making money and attracting as little attention as possible.”

Most ransomware groups maintain flashy victim leak sites which threaten to publish the target’s stolen data unless a ransom demand is paid. But the Dark Angels didn’t even have a victim shaming site until April 2023. And the leak site isn’t particularly well branded; it’s called Dunghill Leak.

The Dark Angels victim shaming site, Dunghill Leak.

“Nothing about them is flashy,” Stone-Gross said. “For the longest time, they didn’t even want to cause a big headline, but they probably felt compelled to create that leaks site because they wanted to show they were serious and that they were going to post victim data and make it accessible.”

Dark Angels is thought to be a Russia-based cybercrime syndicate whose distinguishing characteristic is stealing truly staggering amounts of data from major companies across multiple sectors, including healthcare, finance, government and education. For large businesses, the group has exfiltrated between 10-100 terabytes of data, which can take days or weeks to transfer, ThreatLabz found.

Like most ransom gangs, Dark Angels will publish data stolen from victims who do not pay. Some of the more notable victims listed on Dunghill Leak include the global food distribution firm Sysco, which disclosed a ransomware attack in May 2023; and the travel booking giant Sabre, which was hit by the Dark Angels in September 2023.

Stone-Gross said Dark Angels is often reluctant to deploy ransomware malware because such attacks work by locking up the target’s IT infrastructure, which typically causes the victim’s business to grind to a halt for days, weeks or even months on end. And those types of breaches tend to make headlines quickly.

“They selectively choose whether they want to deploy ransomware or not,” he said. “If they deem they can encrypt some files that won’t cause major disruptions — but will give them a ton of data — that’s what they’ll do. But really, what separates them from the rest is the volume of data they’re stealing. It’s a whole order of magnitude greater with Dark Angels. Companies losing vast amounts of data will pay these high ransoms.”

So who paid the record $75 million ransom? Bleeping Computer posited on July 30 that the victim was the pharmaceutical giant Cencora (formerly AmeriSourceBergen Corporation), which reported a data security incident to the U.S. Securities and Exchange Commission (SEC) on February 21, 2024.

The SEC requires publicly-traded companies to disclose a potentially material cybersecurity event within four days of the incident. Cencora is currently #10 on the Fortune 500 list, generating more than $262 billion in revenue last year.

Cencora did not respond to questions about whether it had made a ransom payment in connection with the February cybersecurity incident, and referred KrebsOnSecurity to expenses listed under “Other” in the restructuring section of their latest quarterly financial report (PDF). That report states that the majority of the $30 million cost in “Other” was associated with the breach.

Cencora’s quarterly statement said the incident affected a standalone legacy information technology platform in one country and the foreign business unit’s ability to operate in that country for approximately two weeks.

Cencora’s 2024 1st quarter report documents a $30 million cost associated with a data exfiltration event in mid-February 2024.

In its most recent State of Ransomware report (PDF), security firm Sophos found the average ransomware payment had increased fivefold in the past year, from $400,000 in 2023 to $2 million. Sophos says that in more than four-fifths (82%) of cases funding for the ransom came from multiple sources. Overall, 40% of total ransom funding came from the organizations themselves and 23% from insurance providers.

Twenty-four prisoners were freed today in an international prisoner swap between Russia and Western countries. Among the eight Russians repatriated were five convicted cybercriminals. In return, Russia has reportedly released 16 prisoners, including Wall Street Journal reporter Evan Gershkovich and ex-U.S. Marine Paul Whelan.

Among the more notable Russian hackers released in the prisoner swap is Roman Seleznev, 40, who was sentenced in 2017 to 27 years in prison for racketeering convictions tied to a lengthy career in stealing and selling payment card data. Seleznev earned this then-record sentence by operating some of the underground’s most bustling marketplaces for stolen card data.

Once known by the hacker handles “Track2,” “Bulba” and “nCux,” Seleznev is the son of Valery Seleznev, a prominent member of the Russian parliament who is considered an ally of Vladimir Putin. U.S. prosecutors showed that for years Vinnik stayed a step ahead of the law by tapping into contacts at the Russian FSB, the successor agency to the Soviet KGB, and by periodically changing hacker handles.

But in 2014 Seleznev was captured by U.S. Secret Service agents, who had zeroed in on Seleznev’s posh vacation spot in The Maldives. At the time, the South Asian island country was a popular destination for Eastern Europe-based cybercriminals, who viewed it as beyond the reach of U.S. law enforcement.

In addition to receiving a record prison sentence, Seleznev was ordered to pay more than $50 million in restitution to his victims. That loss amount equaled the total losses inflicted by Seleznev’s various carding stores, and other thefts attributed to members of the hacking forum carder[.]su, a bustling cybercrime community of which Seleznev was a leading organizer.

Also released in the prisoner swap was Vladislav Klyushin, a 42-year-old Muscovite sentenced in September 2023 to nine years in prison for what U.S. prosecutors called a “$93 million hack-to-trade conspiracy.” Klyushin and his crew hacked into companies and used information stolen in those intrusions to make illegal stock trades.

Klyushin likewise was arrested while vacationing abroad: The Associated Press reported that Klyushin was captured in Switzerland after arriving on a private jet, and just before he and his party were about to board a helicopter to whisk them to a nearby ski resort.

Klyushin is the owner of M-13, a Russian technology company that contracts with the Russian government. According to prosecutors, M-13 offered penetration testing and “advanced persistent threat (APT) emulation.” As part of his guilty plea, Klyushin was also ordered to forfeit $34 million, and to pay restitution in an amount that was to be determined.

The U.S. government says four of Klyushin’s alleged co-conspirators remain at large, including Ivan Ermakov, who was among 12 Russians charged in 2018 with hacking into key Democratic Party email accounts.

Russia also welcomed home one of its most accomplished money launderers. Alexander Vinnik, 44, who was one of the operators of BTC-e, a large cryptocurrency exchange that helped launder crime proceeds tied to various ransomware groups.

In 2017, U.S. authorities seized BTC-e, charging Vinnik with operating an international money laundering scheme that included some 850,000 bitcoins stolen from cryptocurrency exchange Mt. Gox. In May 2024, Vinnik pleaded guilty to laundering more than $9 billion.

Vladimir Dunaev, 40, was one of the masterminds behind the Trickbot trojan, a crimeware-as-a-service platform that for many years was used by Russian cybercrime groups to install ransomware and siphon data from victims. Duanev was sentenced in January 2024 to five years and four months in prison.

The fifth convicted Russian sent back home this week is Maxim Marchenko, 52, who pleaded guilty in February 2024 to illicitly procuring large quantities of U.S.-made microelectronics on behalf of Russian clients in support of the war on Ukraine.

Marchenko admitted setting up a number of shell companies based in Hong Kong that were used to acquire the technology products that have military-grade applications, such as rifle scopes, night vision goggles and thermal optics.

Among the Americans freed by Russia were Wall Street Journal reporter Evan Gershkovich, 32, who has spent the last 16 months in a Russian prison on spying charges. Also released was Alsu Kurmasheva, 47, a Russian American editor for Radio Free Europe/Radio Liberty who was arrested last year; and Paul Whelan, 54, a former U.S. Marine arrested in 2018 and accused of spying.

The New York Times reports several others freed by Russia were German nationals, including German Moyzhes, a lawyer who was helping Russians obtain residence permits in Germany and other E.U. countries. The Times says Slovenia, Norway and Poland released four people accused of being Russian spies.

Reuters reports that Germany released Vadim Krasikov, an FSB colonel serving a life sentence there for murdering an exiled Chechen-Georgian dissident in a Berlin park.

More than a million domain names — including many registered by Fortune 100 firms and brand protection companies — are vulnerable to takeover by cybercriminals thanks to authentication weaknesses at a number of large web hosting providers and domain registrars, new research finds.

Image: Shutterstock.

Your Web browser knows how to find a site like example.com thanks to the global Domain Name System (DNS), which serves as a kind of phone book for the Internet by translating human-friendly website names (example.com) into numeric Internet addresses.

When someone registers a domain name, the registrar will typically provide two sets of DNS records that the customer then needs to assign to their domain. Those records are crucial because they allow Web browsers to find the Internet address of the hosting provider that is serving that domain.

But potential problems can arise when a domain’s DNS records are “lame,” meaning the authoritative name server does not have enough information about the domain and can’t resolve queries to find it. A domain can become lame in a variety of ways, such as when it is not assigned an Internet address, or because the name servers in the domain’s authoritative record are misconfigured or missing.

The reason lame domains are problematic is that a number of Web hosting and DNS providers allow users to claim control over a domain without accessing the true owner’s account at their DNS provider or registrar.

If this threat sounds familiar, that’s because it is hardly new. Back in 2019, KrebsOnSecurity wrote about thieves employing this method to seize control over thousands of domains registered at GoDaddy, and using those to send bomb threats and sextortion emails (GoDaddy says they fixed that weakness in their systems not long after that 2019 story).

In the 2019 campaign, the spammers created accounts on GoDaddy and were able to take over vulnerable domains simply by registering a free account at GoDaddy and being assigned the same DNS servers as the hijacked domain.

Three years before that, the same pervasive weakness was described in a blog post by security researcher Matthew Bryant, who showed how one could commandeer at least 120,000 domains via DNS weaknesses at some of the world’s largest hosting providers.

Incredibly, new research jointly released today by security experts at Infoblox and Eclypsium finds this same authentication weakness is still present at a number of large hosting and DNS providers.

“It’s easy to exploit, very hard to detect, and it’s entirely preventable,” said Dave Mitchell, principal threat researcher at Infoblox. “Free services make it easier [to exploit] at scale. And the bulk of these are at a handful of DNS providers.”

SITTING DUCKS

Infoblox’s report found there are multiple cybercriminal groups abusing these stolen domains as a globally dispersed “traffic distribution system,” which can be used to mask the true source or destination of web traffic and to funnel Web users to malicious or phishous websites.

Commandeering domains this way also can allow thieves to impersonate trusted brands and abuse their positive or at least neutral reputation when sending email from those domains, as we saw in 2019 with the GoDaddy attacks.

“Hijacked domains have been used directly in phishing attacks and scams, as well as large spam systems,” reads the Infoblox report, which refers to lame domains as “Sitting Ducks.” “There is evidence that some domains were used for Cobalt Strike and other malware command and control (C2). Other attacks have used hijacked domains in targeted phishing attacks by creating lookalike subdomains. A few actors have stockpiled hijacked domains for an unknown purpose.”

Eclypsium researchers estimate there are currently about one million Sitting Duck domains, and that at least 30,000 of them have been hijacked for malicious use since 2019.

“As of the time of writing, numerous DNS providers enable this through weak or nonexistent verification of domain ownership for a given account,” Eclypsium wrote.

The security firms said they found a number of compromised Sitting Duck domains were originally registered by brand protection companies that specialize in defensive domain registrations (reserving look-alike domains for top brands before those names can be grabbed by scammers) and combating trademark infringement.

For example, Infoblox found cybercriminal groups using a Sitting Duck domain called clickermediacorp[.]com, which was initially registered on behalf of CBS Interactive Inc. by the brand protection firm MarkMonitor.

Another hijacked Sitting Duck domain — anti-phishing[.]org — was registered in 2003 by the Anti-Phishing Working Group (APWG), a cybersecurity not-for-profit organization that closely tracks phishing attacks.

In many cases, the researchers discovered Sitting Duck domains that appear to have been configured to auto-renew at the registrar, but the authoritative DNS or hosting services were not renewed.

The researchers say Sitting Duck domains all possess three attributes that makes them vulnerable to takeover:

1) the domain uses or delegates authoritative DNS services to a different provider than the domain registrar;
2) the authoritative name server(s) for the domain does not have information about the Internet address the domain should point to;
3) the authoritative DNS provider is “exploitable,” i.e. an attacker can claim the domain at the provider and set up DNS records without access to the valid domain owner’s account at the domain registrar.

How does one know whether a DNS provider is exploitable? There is a frequently updated list published on GitHub called “Can I take over DNS,” which has been documenting exploitability by DNS provider over the past several years. The list includes examples for each of the named DNS providers.

In the case of the aforementioned Sitting Duck domain clickermediacorp[.]com, the domain was originally registered by MarkMonitor, but it appears to have been hijacked by scammers by claiming it at the web hosting firm DNSMadeEasy, which is owned by Digicert, one of the industry’s largest issuers of digital certificates (SSL/TLS certificates).

In an interview with KrebsOnSecurity, DNSMadeEasy founder and senior vice president Steve Job said the problem isn’t really his company’s to solve, noting that DNS providers who are also not domain registrars have no real way of validating whether a given customer legitimately owns the domain being claimed.

“We do shut down abusive accounts when we find them,” Job said. “But it’s my belief that the onus needs to be on the [domain registrants] themselves. If you’re going to buy something and point it somewhere you have no control over, we can’t prevent that.”

Infoblox, Eclypsium, and the DNS wiki listing at Github all say that web hosting giant Digital Ocean is among the vulnerable hosting firms. In response to questions, Digital Ocean said it was exploring options for mitigating such activity.

“The DigitalOcean DNS service is not authoritative, and we are not a domain registrar,” Digital Ocean wrote in an emailed response. “Where a domain owner has delegated authority to our DNS infrastructure with their registrar, and they have allowed their ownership of that DNS record in our infrastructure to lapse, that becomes a ‘lame delegation’ under this hijack model. We believe the root cause, ultimately, is poor management of domain name configuration by the owner, akin to leaving your keys in your unlocked car, but we acknowledge the opportunity to adjust our non-authoritative DNS service guardrails in an effort to help minimize the impact of a lapse in hygiene at the authoritative DNS level. We’re connected with the research teams to explore additional mitigation options.”

In a statement provided to KrebsOnSecurity, the hosting provider and registrar Hostinger said they were working to implement a solution to prevent lame duck attacks in the “upcoming weeks.”

“We are working on implementing an SOA-based domain verification system,” Hostinger wrote. “Custom nameservers with a Start of Authority (SOA) record will be used to verify whether the domain truly belongs to the customer. We aim to launch this user-friendly solution by the end of August. The final step is to deprecate preview domains, a functionality sometimes used by customers with malicious intents. Preview domains will be deprecated by the end of September. Legitimate users will be able to use randomly generated temporary subdomains instead.”

What did DNS providers that have struggled with this issue in the past do to address these authentication challenges? The security firms said that to claim a domain name, the best practice providers gave the account holder random name servers that required a change at the registrar before the domains could go live. They also found the best practice providers used various mechanisms to ensure that the newly assigned name server hosts did not match previous name server assignments.

[Side note: Infoblox observed that many of the hijacked domains were being hosted at Stark Industries Solutions, a sprawling hosting provider that appeared two weeks before Russia invaded Ukraine and has become the epicenter of countless cyberattacks against enemies of Russia].

Both Infoblox and Eclypsium said that without more cooperation and less finger-pointing by all stakeholders in the global DNS, attacks on sitting duck domains will continue to rise, with domain registrants and regular Internet users caught in the middle.

“Government organizations, regulators, and standards bodies should consider long-term solutions to vulnerabilities in the DNS management attack surface,” the Infoblox report concludes.

The Chinese company in charge of handing out domain names ending in “.top” has been given until mid-August 2024 to show that it has put in place systems for managing phishing reports and suspending abusive domains, or else forfeit its license to sell domains. The warning comes amid the release of new findings that .top was the most common suffix in phishing websites over the past year, second only to domains ending in “.com.”

On July 16, the Internet Corporation for Assigned Names and Numbers (ICANN) sent a letter to the owners of the .top domain registry. ICANN has filed hundreds of enforcement actions against domain registrars over the years, but this is thought to be the first in which ICANN has singled out a domain registry responsible for maintaining an entire top-level domain (TLD).

Among other reasons, the missive chided the registry for failing to respond to reports about phishing attacks involving .top domains.

“Based on the information and records gathered through several weeks, it was determined that .TOP Registry does not have a process in place to promptly, comprehensively, and reasonably investigate and act on reports of DNS Abuse,” the ICANN letter reads (PDF).

ICANN’s warning redacted the name of the recipient, but records show the .top registry is operated by a Chinese entity called Jiangsu Bangning Science & Technology Co. Ltd. Representatives for the company have not responded to requests for comment.

Domains ending in .top were represented prominently in a new phishing report released today by the Interisle Consulting Group, which sources phishing data from several places, including the Anti-Phishing Working Group (APWG), OpenPhish, PhishTank, and Spamhaus.

Interisle’s newest study examined nearly two million phishing attacks in the last year, and found that phishing sites accounted for more than four percent of all new .top domains between May 2023 and April 2024. Interisle said .top has roughly 2.76 million domains in its stable, and that more than 117,000 of those were phishing sites in the past year.

ICANN said its review was based on information collected and studied about .top domains over the past few weeks. But the fact that high volumes of phishing sites are being registered through Jiangsu Bangning Science & Technology Co Ltd. is hardly a new trend.

For example, more than 10 years ago the same Chinese registrar was the fourth most common source of phishing websites, as tracked by the APWG. Bear in mind that the APWG report excerpted below was published more than a year before Jiangsu Bangning received ICANN approval to introduce and administer the new .top registry.

A fascinating new wrinkle in the phishing landscape is the growth in scam pages hosted via the InterPlanetary File System (IPFS), a decentralized data storage and delivery network that is based on peer-to-peer networking. According to Interisle, the use of IPFS to host and launch phishing attacks — which can make phishing sites more difficult to take down — increased a staggering 1,300 percent, to roughly 19,000 phishing sites reported in the last year.

Last year’s report from Interisle found that domain names ending in “.us” — the top-level domain for the United States — were among the most prevalent in phishing scams. While .us domains are not even on the Top 20 list of this year’s study, “.com” maintained its perennial #1 spot as the largest source of phishing domains overall.

A year ago, the phishiest domain registrar by far was Freenom, a now-defunct registrar that handed out free domains in several country-code TLDs, including .tk, .ml, .ga and .cf. Freenom went out of business after being sued by Meta, which alleged Freenom ignored abuse complaints while monetizing traffic to abusive domains.

Following Freenom’s demise, phishers quickly migrated to other new low-cost TLDs and to services that allow anonymous, free domain registrations — particularly subdomain services. For example, Interisle found phishing attacks involving websites created on Google’s blogspot.com skyrocketed last year more than 230 percent. Other subdomain services that saw a substantial growth in domains registered by phishers include weebly.com, github.io, wix.com, and ChangeIP, the report notes.

Interisle Consulting partner Dave Piscitello said ICANN could easily send similar warning letters to at least a half-dozen other top-level domain registries, noting that spammers and phishers tend to cycle through the same TLDs periodically — including .xyz, .info, .support and .lol, all of which saw considerably more business from phishers after Freenom’s implosion.

Piscitello said domain registrars and registries could significantly reduce the number of phishing sites registered through their services just by flagging customers who try to register huge volumes of domains at once. Their study found that at least 27% of the domains used for phishing were registered in bulk — i.e. the same registrant paid for hundreds or thousands of domains in quick succession.

The report includes a case study in which a phisher this year registered 17,562 domains over the course of an eight-hour period — roughly 38 domains per minute — using .lol domains that were all composed of random letters.

ICANN tries to resolve contract disputes privately with the registry and registrar community, and experts say the nonprofit organization usually only publishes enforcement letters when the recipient is ignoring its private notices. Indeed, ICANN’s letter notes Jiangsu Bangning didn’t even open its emailed notifications. It also cited the registry for falling behind in its ICANN membership fees.

With that in mind, a review of ICANN’s public enforcement activity suggests two trends: One is that there have been far fewer public compliance and enforcement actions in recent years — even as the number of new TLDs has expanded dramatically.

The second is that in a majority of cases, the failure of a registry or registrar to pay its annual ICANN membership fees was cited as a reason for a warning letter. A review of nearly two dozen enforcement letters ICANN has sent to domain registrars since 2022 shows that failure to pay dues was cited as a reason (or the reason) for the violation at least 75 percent of the time.

Piscitello, a former ICANN board member, said nearly all breach notices sent out while he was at ICANN were because the registrar owed money.

“I think the rest is just lipstick to suggest that ICANN’s on top of DNS Abuse,” Piscitello said.

KrebsOnSecurity has sought comment from ICANN and will update this story if they respond.

A faulty software update from cybersecurity vendor Crowdstrike crippled countless Microsoft Windows computers across the globe today, disrupting everything from airline travel and financial institutions to hospitals and businesses online. Crowdstrike said a fix has been deployed, but experts say the recovery from this outage could take some time, as Crowdstrike’s solution needs to be applied manually on a per-machine basis.

Earlier today, an errant update shipped by Crowdstrike began causing Windows machines running the software to display the dreaded “Blue Screen of Death,” rendering those systems temporarily unusable. Like most security software, Crowdstrike requires deep hooks into the Windows operating system to fend off digital intruders, and in that environment a tiny coding error can quickly lead to catastrophic outcomes.

In a post on Twitter/X, Crowdstrike CEO George Kurtz said an update to correct the coding mistake has been shipped, and that Mac and Linux systems are not affected.

“This is not a security incident or cyberattack,” Kurtz said on Twitter, echoing a written statement by Crowdstrike. “The issue has been identified, isolated and a fix has been deployed.”

Posting to Twitter/X, the director of Crowdstrike’s threat hunting operations said the fix involves booting Windows into Safe Mode or the Windows Recovery Environment (Windows RE), deleting the file “C-00000291*.sys” and then restarting the machine.

The software snafu may have been compounded by a recent series of outages involving Microsoft’s Azure cloud services, The New York Times reports, although it remains unclear whether those Azure problems are at all related to the bad Crowdstrike update.

Reactions to today’s outage were swift and brutal on social media, which was flooded with images of people at airports surrounded by computer screens displaying the Microsoft blue screen error. Many Twitter/X users chided the Crowdstrike CEO for failing to apologize for the massively disruptive event, while others noted that doing so could expose the company to lawsuits.

Meanwhile, the international Windows outage quickly became the most talked-about subject on Twitter/X, whose artificial intelligence bots collated a series of parody posts from cybersecurity professionals pretending to be on their first week of work at Crowdstrike. Incredibly,Twitter/X’s AI summarized these sarcastic posts into a sunny, can-do story about Crowdstrike that was promoted as the top discussion on Twitter this morning.

“Several individuals have recently started working at the cybersecurity firm Crowdstrike and have expressed their excitement and pride in their new roles,” the AI summary read. “They have shared their experiences of pushing code to production on their first day and are looking forward to positive outcomes in their work.”

The top story today on Twitter/X, as brilliantly summarized by X’s AI bots.

Matt Burgess at Wired writes that within health care and emergency services, various medical providers around the world have reported issues with their Windows-linked systems, sharing news on social media or their own websites.

“The US Emergency Alert System, which issues hurricane warnings, said that there had been various 911 outages in a number of states,” Burgess wrote. “Germany’s University Hospital Schleswig-Holstein said it was canceling some nonurgent surgeries at two locations. In Israel, more than a dozen hospitals have been impacted, as well as pharmacies, with reports saying ambulances have been rerouted to nonimpacted medical organizations.”

In the United Kingdom, NHS England has confirmed that appointment and patient record systems have been impacted by the outages.

“One hospital has declared a ‘critical’ incident after a third-party IT system it used was impacted,” Wired reports. “Also in the country, train operators have said there are delays across the network, with multiple companies being impacted.”

This is an evolving story. Stay tuned for updates.

At least a dozen organizations with domain names at domain registrar Squarespace saw their websites hijacked last week. Squarespace bought all assets of Google Domains a year ago, but many customers still haven’t set up their new accounts. Experts say malicious hackers learned they could commandeer any migrated Squarespace accounts that hadn’t yet been registered, merely by supplying an email address tied to an existing domain.

Until this past weekend, Squarespace’s website had an option to log in via email.

The Squarespace domain hijacks, which took place between July 9 and July 12, appear to have mostly targeted cryptocurrency businesses, including Celer Network, Compound Finance, Pendle Finance, and Unstoppable Domains. In some cases, the attackers were able to redirect the hijacked domains to phishing sites set up to steal visitors’ cryptocurrency funds.

New York City-based Squarespace purchased roughly 10 million domain names from Google Domains in June 2023, and it has been gradually migrating those domains to its service ever since. Squarespace has not responded to a request for comment, nor has it issued a statement about the attacks.

But an analysis released by security experts at Metamask and Paradigm finds the most likely explanation for what happened is that Squarespace assumed all users migrating from Google Domains would select the social login options — such “Continue with Google” or “Continue with Apple” — as opposed to the “Continue with email” choice.

Taylor Monahan, lead product manager at Metamask, said Squarespace never accounted for the possibility that a threat actor might sign up for an account using an email associated with a recently-migrated domain before the legitimate email holder created the account themselves.

“Thus nothing actually stops them from trying to login with an email,” Monahan told KrebsOnSecurity. “And since there’s no password on the account, it just shoots them to the ‘create password for your new account’ flow. And since the account is half-initialized on the backend, they now have access to the domain in question.”

What’s more, Monahan said, Squarespace did not require email verification for new accounts created with a password.

“The domains being migrated from Google to Squarespace are known,” Monahan said. “It’s either public or easily discernible info which email addresses have admin of a domain. And if that email never sets up their account on Squarespace — say because the billing admin left the company five years ago or folks just ignored the email — anyone who enters that email@domain in the squarespace form now has full access to control to the domain.”

The researchers say some Squarespace domains that were migrated over also could be hijacked if attackers discovered the email addresses for less privileged user accounts tied to the domain, such as “domain manager,” which likewise has the ability to transfer a domain or point it to a different Internet address.

Squarespace says domain owners and domain managers have many of the same privileges, including the ability to move a domain or manage the site’s domain name server (DNS) settings.

Monahan said the migration has left domain owners with fewer options to secure and monitor their accounts.

“Squarespace can’t support users who need any control or insight into the activity being performed in their account or domain,” Monahan said. “You basically have no control over the access different folks have. You don’t have any audit logs. You don’t get email notifications for some actions. The owner doesn’t get email notification for actions taken by a ‘domain manager.’ This is absolutely insane if you’re used to and expecting the controls Google provides.”

The researchers have published a comprehensive guide for locking down Squarespace user accounts, which urges Squarespace users to enable multi-factor authentication (disabled during the migration).

“Determining what emails have access to your new Squarespace account is step 1,” the help guide advises. “Most teams DO NOT REALIZE these accounts even exist, let alone theoretically have access.”

The guide also recommends removing unnecessary Squarespace user accounts, and disabling reseller access in Google Workspace.

“If you bought Google Workspace via Google Domains, Squarespace is now your authorized reseller,” the help document explains. “This means that anyone with access to your Squarespace account also has a backdoor into your Google Workspace unless you explicitly disable it by following the instructions here, which you should do. It’s easier to secure one account than two.”
