Thread hijacking attacks. They happen when someone you know has their email account compromised, and you are suddenly dropped into an existing conversation between the sender and someone else. These missives draw on the recipient’s natural curiosity about being copied on a private discussion, which is modified to include a malicious link or attachment. Here’s the story of a thread hijacking attack in which a journalist was copied on a phishing email from the unwilling subject of a recent scoop.
In Sept. 2023, the Pennsylvania news outlet LancasterOnline.com published a story about Adam Kidan, a wealthy businessman with a criminal past who is a major donor to Republican causes and candidates, including Rep. Lloyd Smucker (R-Pa).
The LancasterOnline story about Adam Kidan.
Several months after that piece ran, the story’s author Brett Sholtis received two emails from Kidan, both of which contained attachments. One of the messages appeared to be a lengthy conversation between Kidan and a colleague, with the subject line, “Re: Successfully sent data.” The second missive was a more brief email from Kidan with the subject, “Acknowledge New Work Order,” and a message that read simply, “Please find the attached.”
Sholtis said he clicked the attachment in one of the messages, which then launched a web page that looked exactly like a Microsoft Office 365 login page. An analysis of the webpage reveals it would check any submitted credentials at the real Microsoft website, and return an error if the user entered bogus account information. A successful login would record the submitted credentials and forward the victim to the real Microsoft website.
But Sholtis said he didn’t enter his Outlook username and password. Instead, he forwarded the messages to LancasterOneline’s IT team, which quickly flagged them as phishing attempts.
LancasterOnline Executive Editor Tom Murse said the two phishing messages from Mr. Kidan raised eyebrows in the newsroom because Kidan had threatened to sue the news outlet multiple times over Sholtis’s story.
“We were just perplexed,” Murse said. “It seemed to be a phishing attempt but we were confused why it would come from a prominent businessman we’ve written about. Our initial response was confusion, but we didn’t know what else to do with it other than to send it to the FBI.”
The phishing lure attached to the thread hijacking email from Mr. Kidan.
In 2006, Kidan was sentenced to 70 months in federal prison after pleading guilty to defrauding lenders along with Jack Abramoff, the disgraced lobbyist whose corruption became a symbol of the excesses of Washington influence peddling. He was paroled in 2009, and in 2014 moved his family to a home in Lancaster County, Pa.
The FBI hasn’t responded to LancasterOnline’s tip. Messages sent by KrebsOnSecurity to Kidan’s emails addresses were returned as blocked. Messages left with Mr. Kidan’s company, Empire Workforce Solutions, went unreturned.
No doubt the FBI saw the messages from Kidan for what they likely were: The result of Mr. Kidan having his Microsoft Outlook account compromised and used to send malicious email to people in his contacts list.
Thread hijacking attacks are hardly new, but that is mainly true because many Internet users still don’t know how to identify them. The email security firm Proofpoint says it has tracked north of 90 million malicious messages in the last five years that leverage this attack method.
One key reason thread hijacking is so successful is that these attacks generally do not include the tell that exposes most phishing scams: A fabricated sense of urgency. A majority of phishing threats warn of negative consequences should you fail to act quickly — such as an account suspension or an unauthorized high-dollar charge going through.
In contrast, thread hijacking campaigns tend to patiently prey on the natural curiosity of the recipient.
Ryan Kalember, chief strategy officer at Proofpoint, said probably the most ubiquitous examples of thread hijacking are “CEO fraud” or “business email compromise” scams, wherein employees are tricked by an email from a senior executive into wiring millions of dollars to fraudsters overseas.
But Kalember said these low-tech attacks can nevertheless be quite effective because they tend to catch people off-guard.
“It works because you feel like you’re suddenly included in an important conversation,” Kalember said. “It just registers a lot differently when people start reading, because you think you’re observing a private conversation between two different people.”
Some thread hijacking attacks actually involve multiple threat actors who are actively conversing while copying — but not addressing — the recipient.
“We call these multi-persona phishing scams, and they’re often paired with thread hijacking,” Kalember said. “It’s basically a way to build a little more affinity than just copying people on an email. And the longer the conversation goes on, the higher their success rate seems to be because some people start replying to the thread [and participating] psycho-socially.”
The best advice to sidestep phishing scams is to avoid clicking on links or attachments that arrive unbidden in emails, text messages and other mediums. If you’re unsure whether the message is legitimate, take a deep breath and visit the site or service in question manually — ideally, using a browser bookmark so as to avoid potential typosquatting sites.
It’s not unusual for the data brokers behind people-search websites to use pseudonyms in their day-to-day lives (you would, too). Some of these personal data purveyors even try to reinvent their online identities in a bid to hide their conflicts of interest. But it’s not every day you run across a US-focused people-search network based in China whose principal owners all appear to be completely fabricated identities.
Responding to a reader inquiry concerning the trustworthiness of a site called TruePeopleSearch[.]net, KrebsOnSecurity began poking around. The site offers to sell reports containing photos, police records, background checks, civil judgments, contact information “and much more!” According to LinkedIn and numerous profiles on websites that accept paid article submissions, the founder of TruePeopleSearch is Marilyn Gaskell from Phoenix, Ariz.
The saucy yet studious LinkedIn profile for Marilyn Gaskell.
Ms. Gaskell has been quoted in multiple “articles” about random subjects, such as this article at HRDailyAdvisor about the pros and cons of joining a company-led fantasy football team.
“Marilyn Gaskell, founder of TruePeopleSearch, agrees that not everyone in the office is likely to be a football fan and might feel intimidated by joining a company league or left out if they don’t join; however, her company looked for ways to make the activity more inclusive,” this paid story notes.
Also quoted in this article is Sally Stevens, who is cited as HR Manager at FastPeopleSearch[.]io.
Sally Stevens, the phantom HR Manager for FastPeopleSearch.
“Fantasy football provides one way for employees to set aside work matters for some time and have fun,” Stevens contributed. “Employees can set a special league for themselves and regularly check and compare their scores against one another.”
Imagine that: Two different people-search companies mentioned in the same story about fantasy football. What are the odds?
Both TruePeopleSearch and FastPeopleSearch allow users to search for reports by first and last name, but proceeding to order a report prompts the visitor to purchase the file from one of several established people-finder services, including BeenVerified, Intelius, and Spokeo.
DomainTools.com shows that both TruePeopleSearch and FastPeopleSearch appeared around 2020 and were registered through Alibaba Cloud, in Beijing, China. No other information is available about these domains in their registration records, although both domains appear to use email servers based in China.
Sally Stevens’ LinkedIn profile photo is identical to a stock image titled “beautiful girl” from Adobe.com. Ms. Stevens is also quoted in a paid blog post at ecogreenequipment.com, as is Alina Clark, co-founder and marketing director of CocoDoc, an online service for editing and managing PDF documents.
The profile photo for Alina Clark is a stock photo appearing on more than 100 websites.
Scouring multiple image search sites reveals Ms. Clark’s profile photo on LinkedIn is another stock image that is currently on more than 100 different websites, including Adobe.com. Cocodoc[.]com was registered in June 2020 via Alibaba Cloud Beijing in China.
The same Alina Clark and photo materialized in a paid article at the website Ceoblognation, which in 2021 included her at #11 in a piece called “30 Entrepreneurs Describe The Big Hairy Audacious Goals (BHAGs) for Their Business.” It’s also worth noting that Ms. Clark is currently listed as a “former Forbes Council member” at the media outlet Forbes.com.
Entrepreneur #6 is Stephen Curry, who is quoted as CEO of CocoSign[.]com, a website that claims to offer an “easier, quicker, safer eSignature solution for small and medium-sized businesses.” Incidentally, the same photo for Stephen Curry #6 is also used in this “article” for #22 Jake Smith, who is named as the owner of a different company.
Stephen Curry, aka Jake Smith, aka no such person.
Mr. Curry’s LinkedIn profile shows a young man seated at a table in front of a laptop, but an online image search shows this is another stock photo. Cocosign[.]com was registered in June 2020 via Alibaba Cloud Beijing. No ownership details are available in the domain registration records.
Listed at #13 in that 30 Entrepreneurs article is Eden Cheng, who is cited as co-founder of PeopleFinderFree[.]com. KrebsOnSecurity could not find a LinkedIn profile for Ms. Cheng, but a search on her profile image from that Entrepreneurs article shows the same photo for sale at Shutterstock and other stock photo sites.
DomainTools says PeopleFinderFree was registered through Alibaba Cloud, Beijing. Attempts to purchase reports through PeopleFinderFree produce a notice saying the full report is only available via Spokeo.com.
Lynda Fairly is Entrepreneur #24, and she is quoted as co-founder of Numlooker[.]com, a domain registered in April 2021 through Alibaba in China. Searches for people on Numlooker forward visitors to Spokeo.
The photo next to Ms. Fairly’s quote in Entrepreneurs matches that of a LinkedIn profile for Lynda Fairly. But a search on that photo shows this same portrait has been used by many other identities and names, including a woman from the United Kingdom who’s a cancer survivor and mother of five; a licensed marriage and family therapist in Canada; a software security engineer at Quora; a journalist on Twitter/X; and a marketing expert in Canada.
Cocofinder[.]com is a people-search service that launched in Sept. 2019, through Alibaba in China. Cocofinder lists its market officer as Harriet Chan, but Ms. Chan’s LinkedIn profile is just as sparse on work history as the other people-search owners mentioned already. An image search online shows that outside of LinkedIn, the profile photo for Ms. Chan has only ever appeared in articles at pay-to-play media sites, like this one from outbackteambuilding.com.
Perhaps because Cocodoc and Cocosign both sell software services, they are actually tied to a physical presence in the real world — in Singapore (15 Scotts Rd. #03-12 15, Singapore). But it’s difficult to discern much from this address alone.
Who’s behind all this people-search chicanery? A January 2024 review of various people-search services at the website techjury.com states that Cocofinder is a wholly-owned subsidiary of a Chinese company called Shenzhen Duiyun Technology Co.
“Though it only finds results from the United States, users can choose between four main search methods,” Techjury explains. Those include people search, phone, address and email lookup. This claim is supported by a Reddit post from three years ago, wherein the Reddit user “ProtectionAdvanced” named the same Chinese company.
Is Shenzhen Duiyun Technology Co. responsible for all these phony profiles? How many more fake companies and profiles are connected to this scheme? KrebsOnSecurity found other examples that didn’t appear directly tied to other fake executives listed here, but which nevertheless are registered through Alibaba and seek to drive traffic to Spokeo and other data brokers. For example, there’s the winsome Daniela Sawyer, founder of FindPeopleFast[.]net, whose profile is flogged in paid stories at entrepreneur.org.
Google currently turns up nothing else for in a search for Shenzhen Duiyun Technology Co. Please feel free to sound off in the comments if you have any more information about this entity, such as how to contact it. Or reach out directly at krebsonsecurity @ gmail.com.

It appears the purpose of this network is to conceal the location of people in China who are seeking to generate affiliate commissions when someone visits one of their sites and purchases a people-search report at Spokeo, for example. And it is clear that Spokeo and others have created incentives wherein anyone can effectively white-label their reports, and thereby make money brokering access to peoples’ personal information.
Spokeo’s Wikipedia page says the company was founded in 2006 by four graduates from Stanford University. Spokeo co-founder and current CEO Harrison Tang has not yet responded to requests for comment.
Intelius is owned by San Diego based PeopleConnect Inc., which also owns Classmates.com, USSearch, TruthFinder and Instant Checkmate. PeopleConnect Inc. in turn is owned by H.I.G. Capital, a $60 billion private equity firm. Requests for comment were sent to H.I.G. Capital. This story will be updated if they respond.
BeenVerified is owned by a New York City based holding company called The Lifetime Value Co., a marketing and advertising firm whose brands include PeopleLooker, NeighborWho, Ownerly, PeopleSmart, NumberGuru, and Bumper, a car history site.
Ross Cohen, chief operating officer at The Lifetime Value Co., said it’s likely the network of suspicious people-finder sites was set up by an affiliate. Cohen said Lifetime Value would investigate to determine if this particular affiliate was driving them any sign-ups.
All of the above people-search services operate similarly. When you find the person you’re looking for, you are put through a lengthy (often 10-20 minute) series of splash screens that require you to agree that these reports won’t be used for employment screening or in evaluating new tenant applications. Still more prompts ask if you are okay with seeing “potentially shocking” details about the subject of the report, including arrest histories and photos.
Only at the end of this process does the site disclose that viewing the report in question requires signing up for a monthly subscription, which is typically priced around $35. Exactly how and from where these major people-search websites are getting their consumer data — and customers — will be the subject of further reporting here.
The main reason these various people-search sites require you to affirm that you won’t use their reports for hiring or vetting potential tenants is that selling reports for those purposes would classify these firms as consumer reporting agencies (CRAs) and expose them to regulations under the Fair Credit Reporting Act (FCRA).
These data brokers do not want to be treated as CRAs, and for this reason their people search reports typically don’t include detailed credit histories, financial information, or full Social Security Numbers (Radaris reports include the first six digits of one’s SSN).
But in September 2023, the U.S. Federal Trade Commission found that TruthFinder and Instant Checkmate were trying to have it both ways. The FTC levied a $5.8 million penalty against the companies for allegedly acting as CRAs because they assembled and compiled information on consumers into background reports that were marketed and sold for employment and tenant screening purposes.
The FTC also found TruthFinder and Instant Checkmate deceived users about background report accuracy. The FTC alleges these companies made millions from their monthly subscriptions using push notifications and marketing emails that claimed that the subject of a background report had a criminal or arrest record, when the record was merely a traffic ticket.
The FTC said both companies deceived customers by providing “Remove” and “Flag as Inaccurate” buttons that did not work as advertised. Rather, the “Remove” button removed the disputed information only from the report as displayed to that customer; however, the same item of information remained visible to other customers who searched for the same person.
The FTC also said that when a customer flagged an item in the background report as inaccurate, the companies never took any steps to investigate those claims, to modify the reports, or to flag to other customers that the information had been disputed.
There are a growing number of online reputation management companies that offer to help customers remove their personal information from people-search sites and data broker databases. There are, no doubt, plenty of honest and well-meaning companies operating in this space, but it has been my experience that a great many people involved in that industry have a background in marketing or advertising — not privacy.
Also, some so-called data privacy companies may be wolves in sheep’s clothing. On March 14, KrebsOnSecurity published an abundance of evidence indicating that the CEO and founder of the data privacy company OneRep.com was responsible for launching dozens of people-search services over the years.
Finally, some of the more popular people-search websites are notorious for ignoring requests from consumers seeking to remove their information, regardless of which reputation or removal service you use. Some force you to create an account and provide more information before you can remove your data. Even then, the information you worked hard to remove may simply reappear a few months later.
This aptly describes countless complaints lodged against the data broker and people search giant Radaris. On March 8, KrebsOnSecurity profiled the co-founders of Radaris, two Russian brothers in Massachusetts who also operate multiple Russian-language dating services and affiliate programs.
The truth is that these people-search companies will continue to thrive unless and 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. Duke University adjunct professor Justin Sherman says virtually all state privacy laws exempt records that might be considered “public” or “government” documents, including voting registries, property filings, marriage certificates, motor vehicle records, criminal records, court documents, death records, professional licenses, bankruptcy filings, and more.
“Consumer privacy laws in California, Colorado, Connecticut, Delaware, Indiana, Iowa, Montana, Oregon, Tennessee, Texas, Utah, and Virginia all contain highly similar or completely identical carve-outs for ‘publicly available information’ or government records,” Sherman said.

If you live in the United States, the data broker Radaris likely knows a great deal about you, and they are happy to sell what they know to anyone. But how much do we know about Radaris? Publicly available data indicates that in addition to running a dizzying array of people-search websites, the co-founders of Radaris operate multiple Russian-language dating services and affiliate programs. It also appears many of their businesses have ties to a California marketing firm that works with a Russian state-run media conglomerate currently sanctioned by the U.S. government.
Formed in 2009, Radaris is a vast people-search network for finding data on individuals, properties, phone numbers, businesses and addresses. Search for any American’s name in Google and the chances are excellent that a listing for them at Radaris.com will show up prominently in the results.
Radaris reports typically bundle a substantial amount of data scraped from public and court documents, including any current or previous addresses and phone numbers, known email addresses and registered domain names. The reports also list address and phone records for the target’s known relatives and associates. Such information could be useful if you were trying to determine the maiden name of someone’s mother, or successfully answer a range of other knowledge-based authentication questions.
Currently, consumer reports advertised for sale at Radaris.com are being fulfilled by a different people-search company called TruthFinder. But Radaris also operates a number of other people-search properties — like Centeda.com — that sell consumer reports directly and behave almost identically to TruthFinder: That is, reel the visitor in with promises of detailed background reports on people, and then charge a $34.99 monthly subscription fee just to view the results.
The Better Business Bureau (BBB) assigns Radaris a rating of “F” for consistently ignoring consumers seeking to have their information removed from Radaris’ various online properties. Of the 159 complaints detailed there in the last year, several were from people who had used third-party identity protection services to have their information removed from Radaris, only to receive a notice a few months later that their Radaris record had been restored.
What’s more, Radaris’ automated process for requesting the removal of your information requires signing up for an account, potentially providing more information about yourself that the company didn’t already have (see screenshot above).
Radaris has not responded to requests for comment.
Radaris, TruthFinder and others like them all force users to agree that their reports will not be used to evaluate someone’s eligibility for credit, or a new apartment or job. This language is so prominent in people-search reports because selling reports for those purposes would classify these firms as consumer reporting agencies (CRAs) and expose them to regulations under the Fair Credit Reporting Act (FCRA).
These data brokers do not want to be treated as CRAs, and for this reason their people search reports typically do not include detailed credit histories, financial information, or full Social Security Numbers (Radaris reports include the first six digits of one’s SSN).
But in September 2023, the U.S. Federal Trade Commission found that TruthFinder and another people-search service Instant Checkmate were trying to have it both ways. The FTC levied a $5.8 million penalty against the companies for allegedly acting as CRAs because they assembled and compiled information on consumers into background reports that were marketed and sold for employment and tenant screening purposes.
An excerpt from the FTC’s complaint against TruthFinder and Instant Checkmate.
The FTC also found TruthFinder and Instant Checkmate deceived users about background report accuracy. The FTC alleges these companies made millions from their monthly subscriptions using push notifications and marketing emails that claimed that the subject of a background report had a criminal or arrest record, when the record was merely a traffic ticket.
“All the while, the companies touted the accuracy of their reports in online ads and other promotional materials, claiming that their reports contain “the MOST ACCURATE information available to the public,” the FTC noted. The FTC says, however, that all the information used in their background reports is obtained from third parties that expressly disclaim that the information is accurate, and that TruthFinder and Instant Checkmate take no steps to verify the accuracy of the information.
The FTC said both companies deceived customers by providing “Remove” and “Flag as Inaccurate” buttons that did not work as advertised. Rather, the “Remove” button removed the disputed information only from the report as displayed to that customer; however, the same item of information remained visible to other customers who searched for the same person.
The FTC also said that when a customer flagged an item in the background report as inaccurate, the companies never took any steps to investigate those claims, to modify the reports, or to flag to other customers that the information had been disputed.
According to Radaris’ profile at the investor website Pitchbook.com, the company’s founder and “co-chief executive officer” is a Massachusetts resident named Gary Norden, also known as Gary Nard.
An analysis of email addresses known to have been used by Mr. Norden shows he is a native Russian man whose real name is Igor Lybarsky (also spelled Lubarsky). Igor’s brother Dmitry, who goes by “Dan,” appears to be the other co-CEO of Radaris. Dmitry Lybarsky’s Facebook/Meta account says he was born in March 1963.
The Lybarsky brothers Dmitry or “Dan” (left) and Igor a.k.a. “Gary,” in an undated photo.
Indirectly or directly, the Lybarskys own multiple properties in both Sherborn and Wellesley, Mass. However, the Radaris website is operated by an offshore entity called Bitseller Expert Ltd, which is incorporated in Cyprus. Neither Lybarsky brother responded to requests for comment.
A review of the domain names registered by Gary Norden shows that beginning in the early 2000s, he and Dan built an e-commerce empire by marketing prepaid calling cards and VOIP services to Russian expatriates who are living in the United States and seeking an affordable way to stay in touch with loved ones back home.
A Sherborn, Mass. property owned by Barsky Real Estate Trust and Dmitry Lybarsky.
In 2012, the main company in charge of providing those calling services — Wellesley Hills, Mass-based Unipoint Technology Inc. — was fined $179,000 by the U.S. Federal Communications Commission, which said Unipoint never applied for a license to provide international telecommunications services.
DomainTools.com shows the email address gnard@unipointtech.com is tied to 137 domains, including radaris.com. DomainTools also shows that the email addresses used by Gary Norden for more than two decades — epop@comby.com, gary@barksy.com and gary1@eprofit.com, among others — appear in WHOIS registration records for an entire fleet of people-search websites, including: centeda.com, virtory.com, clubset.com, kworld.com, newenglandfacts.com, and pub360.com.
Still more people-search platforms tied to Gary Norden– like publicreports.com and arrestfacts.com — currently funnel interested customers to third-party search companies, such as TruthFinder and PersonTrust.com.
The email addresses used by Gary Nard/Gary Norden are also connected to a slew of data broker websites that sell reports on businesses, real estate holdings, and professionals, including bizstanding.com, homemetry.com, trustoria.com, homeflock.com, rehold.com, difive.com and projectlab.com.
Domain records indicate that Gary and Dan for many years operated a now-defunct pay-per-click affiliate advertising network called affiliate.ru. That entity used domain name servers tied to the aforementioned domains comby.com and eprofit.com, as did radaris.ru.
A machine-translated version of Affiliate.ru, a Russian-language site that advertised hundreds of money making affiliate programs, including the Comfi.com prepaid calling card affiliate.
Comby.com used to be a Russian language social media network that looked a great deal like Facebook. The domain now forwards visitors to Privet.ru (“hello” in Russian), a dating site that claims to have 5 million users. Privet.ru says it belongs to a company called Dating Factory, which lists offices in Switzerland. Privet.ru uses the Gary Norden domain eprofit.com for its domain name servers.
Dating Factory’s website says it sells “powerful dating technology” to help customers create unique or niche dating websites. A review of the sample images available on the Dating Factory homepage suggests the term “dating” in this context refers to adult websites. Dating Factory also operates a community called FacebookOfSex, as well as the domain analslappers.com.
Email addresses for the Comby and Eprofit domains indicate Gary Norden operates an entity in Wellesley Hills, Mass. called RussianAmerican Holding Inc. (russianamerica.com). This organization is listed as the owner of the domain newyork.ru, which is a site dedicated to orienting newcomers from Russia to the Big Apple.
Newyork.ru’s terms of service refer to an international calling card company called ComFi Inc. (comfi.com) and list an address as PO Box 81362 Wellesley Hills, Ma. Other sites that include this address are russianamerica.com, russianboston.com, russianchicago.com, russianla.com, russiansanfran.com, russianmiami.com, russiancleveland.com and russianseattle.com (currently offline).
ComFi is tied to Comfibook.com, which was a search aggregator website that collected and published data from many online and offline sources, including phone directories, social networks, online photo albums, and public records.
The current website for russianamerica.com. Note the ad in the bottom left corner of this image for Channel One, a Russian state-owned media firm that is currently sanctioned by the U.S. government.
Many of the U.S. city-specific online properties apparently tied to Gary Norden include phone numbers on their contact pages for a pair of Russian media and advertising firms based in southern California. The phone number 323-874-8211 appears on the websites russianla.com, russiasanfran.com, and rosconcert.com, which sells tickets to theater events performed in Russian.
Historic domain registration records from DomainTools show rosconcert.com was registered in 2003 to Unipoint Technologies — the same company fined by the FCC for not having a license. Rosconcert.com also lists the phone number 818-377-2101.
A phone number just a few digits away — 323-874-8205 — appears as a point of contact on newyork.ru, russianmiami.com, russiancleveland.com, and russianchicago.com. A search in Google shows this 82xx number range — and the 818-377-2101 number — belong to two different entities at the same UPS Store mailbox in Tarzana, Calif: American Russian Media Inc. (armediacorp.com), and Lamedia.biz.
Armediacorp.com is the home of FACT Magazine, a glossy Russian-language publication put out jointly by the American-Russian Business Council, the Hollywood Chamber of Commerce, and the West Hollywood Chamber of Commerce.
Lamedia.biz says it is an international media organization with more than 25 years of experience within the Russian-speaking community on the West Coast. The site advertises FACT Magazine and the Russian state-owned media outlet Channel One. Clicking the Channel One link on the homepage shows Lamedia.biz offers to submit advertising spots that can be shown to Channel One viewers. The price for a basic ad is listed at $500.
In May 2022, the U.S. government levied financial sanctions against Channel One that bar US companies or citizens from doing business with the company.
The website of lamedia.biz offers to sell advertising on two Russian state-owned media firms currently sanctioned by the U.S. government.
In 2014, a group of people sued Radaris in a class-action lawsuit claiming the company’s practices violated the Fair Credit Reporting Act. Court records indicate the defendants never showed up in court to dispute the claims, and as a result the judge eventually awarded the plaintiffs a default judgement and ordered the company to pay $7.5 million.
But the plaintiffs in that civil case had a difficult time collecting on the court’s ruling. In response, the court ordered the radaris.com domain name (~9.4M monthly visitors) to be handed over to the plaintiffs.
However, in 2018 Radaris was able to reclaim their domain on a technicality. Attorneys for the company argued that their clients were never named as defendants in the original lawsuit, and so their domain could not legally be taken away from them in a civil judgment.
“Because our clients were never named as parties to the litigation, and were never served in the litigation, the taking of their property without due process is a violation of their rights,” Radaris’ attorneys argued.
In October 2023, an Illinois resident filed a class-action lawsuit against Radaris for allegedly using people’s names for commercial purposes, in violation of the Illinois Right of Publicity Act.
On Feb. 8, 2024, a company called Atlas Data Privacy Corp. sued Radaris LLC for allegedly violating “Daniel’s Law,” a statute that allows New Jersey law enforcement, government personnel, judges and their families to have their information completely removed from people-search services and commercial data brokers. Atlas has filed at least 140 similar Daniel’s Law complaints against data brokers recently.
Daniel’s Law was enacted in response to the death of 20-year-old Daniel Anderl, who was killed in a violent attack targeting a federal judge (his mother). In July 2020, a disgruntled attorney who had appeared before U.S. District Judge Esther Salas disguised himself as a Fedex driver, went to her home and shot and killed her son (the judge was unharmed and the assailant killed himself).
Earlier this month, The Record reported on Atlas Data Privacy’s lawsuit against LexisNexis Risk Data Management, in which the plaintiffs representing thousands of law enforcement personnel in New Jersey alleged that after they asked for their information to remain private, the data broker retaliated against them by freezing their credit and falsely reporting them as identity theft victims.
Another data broker sued by Atlas Data Privacy — pogodata.com — announced on Mar. 1 that it was likely shutting down because of the lawsuit.
“The matter is far from resolved but your response motivates us to try to bring back most of the names while preserving redaction of the 17,000 or so clients of the redaction company,” the company wrote. “While little consolation, we are not alone in the suit – the privacy company sued 140 property-data sites at the same time as PogoData.”
Atlas says their goal is convince more states to pass similar laws, and to extend those protections to other groups such as teachers, healthcare personnel and social workers. Meanwhile, media law experts say they’re concerned that enacting Daniel’s Law in other states would limit the ability of journalists to hold public officials accountable, and allow authorities to pursue criminals charges against media outlets that publish the same type of public and governments records that fuel the people-search industry.
There are some pending changes to the US legal and regulatory landscape that could soon reshape large swaths of the data broker industry. But experts say it is unlikely that any of these changes will affect people-search companies like Radaris.
On Feb. 28, 2024, the White House issued an executive order that directs the U.S. Department of Justice (DOJ) to create regulations that would prevent data brokers from selling or transferring abroad certain data types deemed too sensitive, including genomic and biometric data, geolocation and financial data, as well as other as-yet unspecified personal identifiers. The DOJ this week published a list of more than 100 questions it is seeking answers to regarding the data broker industry.
In August 2023, the Consumer Financial Protection Bureau (CFPB) announced it was undertaking new rulemaking related to data brokers.
Justin Sherman, an adjunct professor at Duke University, said neither the CFPB nor White House rulemaking will likely address people-search brokers because these companies 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.
“These dossiers contain everything from individuals’ names, addresses, and family information to data about finances, criminal justice system history, and home and vehicle purchases,” Sherman wrote in an October 2023 article for Lawfare. “People search websites’ business pitch boils down to the fact that they have done the work of compiling data, digitizing it, and linking it to specific people so that it can be searched online.”
Sherman said while there are ongoing debates about whether people search data brokers have legal responsibilities to the people about whom they gather and sell data, the sources of this information — public records — are completely carved out from every single state consumer privacy law.
“Consumer privacy laws in California, Colorado, Connecticut, Delaware, Indiana, Iowa, Montana, Oregon, Tennessee, Texas, Utah, and Virginia all contain highly similar or completely identical carve-outs for ‘publicly available information’ or government records,” Sherman wrote. “Tennessee’s consumer data privacy law, for example, stipulates that “personal information,” a cornerstone of the legislation, does not include ‘publicly available information,’ defined as:
“…information that is lawfully made available through federal, state, or local government records, or information that a business has a reasonable basis to believe is lawfully made available to the general public through widely distributed media, by the consumer, or by a person to whom the consumer has disclosed the information, unless the consumer has restricted the information to a specific audience.”
Sherman said this is the same language as the carve-out in the California privacy regime, which is often held up as the national leader in state privacy regulations. He said with a limited set of exceptions for survivors of stalking and domestic violence, even under California’s newly passed Delete Act — which creates a centralized mechanism for consumers to ask some third-party data brokers to delete their information — consumers across the board cannot exercise these rights when it comes to data scraped from property filings, marriage certificates, and public court documents, for example.
“With some very narrow exceptions, it’s either extremely difficult or impossible to compel these companies to remove your information from their sites,” Sherman told KrebsOnSecurity. “Even in states like California, every single consumer privacy law in the country completely exempts publicly available information.”

Microsoft Corp. today pushed software updates to plug more than 70 security holes in its Windows operating systems and related products, including two zero-day vulnerabilities that are already being exploited in active attacks.
Top of the heap on this Fat Patch Tuesday is CVE-2024-21412, a “security feature bypass” in the way Windows handles Internet Shortcut Files that Microsoft says is being targeted in active exploits. Redmond’s advisory for this bug says an attacker would need to convince or trick a user into opening a malicious shortcut file.
Researchers at Trend Micro have tied the ongoing exploitation of CVE-2024-21412 to an advanced persistent threat group dubbed “Water Hydra,” which they say has being using the vulnerability to execute a malicious Microsoft Installer File (.msi) that in turn unloads a remote access trojan (RAT) onto infected Windows systems.
The other zero-day flaw is CVE-2024-21351, another security feature bypass — this one in the built-in Windows SmartScreen component that tries to screen out potentially malicious files downloaded from the Web. Kevin Breen at Immersive Labs says it’s important to note that this vulnerability alone is not enough for an attacker to compromise a user’s workstation, and instead would likely be used in conjunction with something like a spear phishing attack that delivers a malicious file.
Satnam Narang, senior staff research engineer at Tenable, said this is the fifth vulnerability in Windows SmartScreen patched since 2022 and all five have been exploited in the wild as zero-days. They include CVE-2022-44698 in December 2022, CVE-2023-24880 in March 2023, CVE-2023-32049 in July 2023 and CVE-2023-36025 in November 2023.
Narang called special attention to CVE-2024-21410, an “elevation of privilege” bug in Microsoft Exchange Server that Microsoft says is likely to be exploited by attackers. Attacks on this flaw would lead to the disclosure of NTLM hashes, which could be leveraged as part of an NTLM relay or “pass the hash” attack, which lets an attacker masquerade as a legitimate user without ever having to log in.
“We know that flaws that can disclose sensitive information like NTLM hashes are very valuable to attackers,” Narang said. “A Russian-based threat actor leveraged a similar vulnerability to carry out attacks – CVE-2023-23397 is an Elevation of Privilege vulnerability in Microsoft Outlook patched in March 2023.”
Microsoft notes that prior to its Exchange Server 2019 Cumulative Update 14 (CU14), a security feature called Extended Protection for Authentication (EPA), which provides NTLM credential relay protections, was not enabled by default.
“Going forward, CU14 enables this by default on Exchange servers, which is why it is important to upgrade,” Narang said.
Rapid7’s lead software engineer Adam Barnett highlighted CVE-2024-21413, a critical remote code execution bug in Microsoft Office that could be exploited just by viewing a specially-crafted message in the Outlook Preview pane.
“Microsoft Office typically shields users from a variety of attacks by opening files with Mark of the Web in Protected View, which means Office will render the document without fetching potentially malicious external resources,” Barnett said. “CVE-2024-21413 is a critical RCE vulnerability in Office which allows an attacker to cause a file to open in editing mode as though the user had agreed to trust the file.”
Barnett stressed that administrators responsible for Office 2016 installations who apply patches outside of Microsoft Update should note the advisory lists no fewer than five separate patches which must be installed to achieve remediation of CVE-2024-21413; individual update knowledge base (KB) articles further note that partially-patched Office installations will be blocked from starting until the correct combination of patches has been installed.
It’s a good idea for Windows end-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. 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 often 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 Canadian man who says he’s been falsely charged with orchestrating a complex e-commerce scam is seeking to clear his name. His case appears to involve “triangulation fraud,” which occurs when a consumer purchases something online — from a seller on Amazon or eBay, for example — but the seller doesn’t actually own the item for sale. Instead, the seller purchases the item from an online retailer using stolen payment card data. In this scam, the unwitting buyer pays the scammer and receives what they ordered, and very often the only party left to dispute the transaction is the owner of the stolen payment card.

Timothy Barker, 56, was until recently a Band Manager at Duncan’s First Nation, a First Nation in northwestern Alberta, Canada. A Band Manager is responsible for overseeing the delivery of all Band programs, including community health services, education, housing, social assistance, and administration.
Barker told KrebsOnSecurity that during the week of March 31, 2023 he and the director of the Band’s daycare program discussed the need to purchase items for the community before the program’s budget expired for the year.
“There was a rush to purchase items on the Fiscal Year 2023 timeline as the year ended on March 31,” Barker recalled.
Barker said he bought seven “Step2 All Around Playtime Patio with Canopy” sets from a seller on Amazon.ca, using his payment card on file to pay nearly $2,000 for the items.
On the morning of April 7, Barker’s Facebook account received several nasty messages from an Ontario woman he’d never met. She demanded to know why he’d hacked her Walmart account and used it to buy things that were being shipped to his residence. Barker shared a follow-up message from the woman, who later apologized for losing her temper.
One of several messages from the Ontario woman whose Walmart account was used to purchase the goods that Barker ordered from Amazon.
“If this is not the person who did this to me, I’m sorry, I’m pissed,” the lady from Ontario said. “This order is being delivered April 14th to the address above. If not you, then someone who has the same name. Now I feel foolish.”
On April 12, 2023, before the Amazon purchases had even arrived at his home, Barker received a call from an investigator with the Royal Canadian Mounted Police (RCMP), who said Barker urgently needed to come down to the local RCMP office for an interview related to “an investigation.” Barker said the officer wouldn’t elaborate at the time on the nature of the investigation, and that he told the officer he was in Halifax for several days but could meet after his return home.
According to Barker, the investigator visited his home anyway the following day and began questioning his wife, asking about his whereabouts, his work, and when he might return home.
On April 14, six boxes arrived to partially fulfill his Amazon order; another box was delayed, and the Amazon.ca seller he’d purchased from said the remaining box was expected to ship the following week. Barker said he was confused because all six boxes came from Walmart instead of Amazon, and the shipping labels had his name and address on them but carried a contact phone number in Mexico.
Three days later, the investigator called again, demanding he submit to an interview.
“He then asked where my wife was and what her name is,” Barker said. “He wanted to know her itinerary for the day. I am now alarmed and frightened — this doesn’t feel right.”
Barker said he inquired with a local attorney about a consultation, but that the RCMP investigator showed up at his house before he could speak to the lawyer. The investigator began taking pictures of the boxes from his Amazon order.
“The [investigator] derisively asked why would anyone order so many play sets?” Barker said. “I started to give the very logical answer that we are helping families improve their children’s home life and learning for toddlers when he cut me off and gave the little speech about giving a statement after my arrest. He finally told me that he believes that I used someone’s credit card in Ontario to purchase the Walmart products.”
Eager to clear his name, Barker said he shared with the police copies of his credit card bills and purchase history at Amazon. But on April 21, the investigator called again to say he was coming to arrest Barker for theft.
“He said that if I was home at five o’clock then he would serve the papers at the house and it would go easy and I wouldn’t have to go to the station,” Barker recalled. “If I wasn’t home, then he would send a search team to locate me and drag me to the station. He said he would kick the door down if I didn’t answer my phone. He said he had every right to break our door down.”
Barker said he briefly conferred with an attorney about how to handle the arrest. Later that evening, the RCMP arrived with five squad cars and six officers.
“I asked if handcuffs were necessary – there is no danger of violence,” Barker said. “I was going to cooperate. His response was to turn me around and cuff me. He walked me outside and stood me beside the car for a full 4 or 5 minutes in full view of all the neighbors.”
Barker believes he and the Ontario woman are both victims of triangulation fraud, and that someone likely hacked the Ontario woman’s Walmart account and added his name and address as a recipient.
But he says he has since lost his job as a result of the arrest, and now he can’t find new employment because he has a criminal record. Barker’s former employer — Duncan’s First Nation — did not respond to requests for comment.
“In Canada, a criminal record is not a record of conviction, it’s a record of charges and that’s why I can’t work now,” Barker said. “Potential employers never find out what the nature of it is, they just find out that I have a criminal arrest record.”
Barker said that right after his arrest, the RCMP called the Ontario woman and told her they’d solved the crime and arrested the perpetrator.
“They even told her my employer had put me on administrative leave,” he said. “Surely, they’re not allowed to do that.”
Contacted by KrebsOnSecurity, the woman whose Walmart account was used to fraudulently purchase the child play sets said she’s not convinced this was a case of triangulation fraud. She declined to elaborate on why she believed this, other than to say the police told her Barker was a bad guy.
“I don’t think triangulation fraud was used in this case,” she said. “My actual Walmart.ca account was hacked and an order was placed on my account, using my credit card. The only thing Mr. Barker did was to order the item to be delivered to his address in Alberta.”
Barker shared with this author all of the documentation he gave to the RCMP, including screenshots of his Amazon.ca account showing that the items in dispute were sold by a seller named “Adavio,” and that the merchant behind this name was based in Turkey.
That Adavio account belongs to a young computer engineering student and “SEO expert” based in Adana, Turkey who did not respond to requests for comment.
Amazon.ca said it conducted an investigation and found that Mr. Barker never filed a complaint about the seller or transaction in question. The company noted that Adavio currently has a feedback rating of 4.5 stars out of 5.
“Amazon works hard to provide customers with a great experience and it’s our commitment to go above and beyond to make things right for customers,” Amazon.ca said in a written statement. “If a customer has an issue with an order, they may flag to Amazon through our Customer Service page.”
Barker said when he went to file a complaint with Amazon last year he could no longer find the Adavio account on the website, and that the site didn’t have a category for the type of complaint he wanted to file.
When he first approached KrebsOnSecurity about his plight last summer, Barker said he didn’t want any media attention to derail the chances of having his day in court, and confronting the RCMP investigator with evidence proving that he was being wrongfully prosecuted and maligned.
But a week before his court date arrived at the end of November 2023, prosecutors announced the charges against him would be stayed, meaning they had no immediate plans to prosecute the case further but that the investigation could still be reopened at some point in the future.
The RCMP declined to comment for this story, other than to confirm they had issued a stay of proceedings in the case.
Barker says the stay has left him in legal limbo — denying him the ability to clear his name, while giving the RCMP a free pass for a botched investigation. He says he has considered suing the investigating officer for defamation, but has been told by his attorney that the bar for success in such cases against the government is extremely high.
“I’m a 56-year-old law-abiding citizen, and I haven’t broken any laws,” Barker said, wondering aloud who would be stupid enough to use someone else’s credit card and have the stolen items shipped directly to their home.
“Their putting a stay on the proceedings without giving any evidence or explanation allows them to cover up bad police work,” he said. “It’s all so stupid.”
Triangulation fraud is hardly a new thing. KrebsOnSecurity first wrote about it from an e-commerce vendor’s perspective in 2015, but the scam predates that story by many years and is now a well-understood problem. The Canadian authorities should either let Mr. Barker have his day in court, or drop the charges altogether.
Microsoft today issued security updates for more than 100 newly-discovered vulnerabilities in its Windows operating system and related software, including four flaws that are already being exploited. In addition, Apple recently released emergency updates to quash a pair of zero-day bugs in iOS.
Apple last week shipped emergency updates in iOS 17.0.3 and iPadOS 17.0.3 in response to active attacks. The patch fixes CVE-2023-42724, which attackers have been using in targeted attacks to elevate their access on a local device.
Apple said it also patched CVE-2023-5217, which is not listed as a zero-day bug. However, as Bleeping Computer pointed out, this flaw is caused by a weakness in the open-source “libvpx” video codec library, which was previously patched as a zero-day flaw by Google in the Chrome browser and by Microsoft in Edge, Teams, and Skype products. For anyone keeping count, this is the 17th zero-day flaw that Apple has patched so far this year.
Fortunately, the zero-days affecting Microsoft customers this month are somewhat less severe than usual, with the exception of CVE-2023-44487. This weakness is not specific to Windows but instead exists within the HTTP/2 protocol used by the World Wide Web: Attackers have figured out how to use a feature of HTTP/2 to massively increase the size of distributed denial-of-service (DDoS) attacks, and these monster attacks reportedly have been going on for several weeks now.
Amazon, Cloudflare and Google all released advisories today about how they’re addressing CVE-2023-44487 in their cloud environments. Google’s Damian Menscher wrote on Twitter/X that the exploit — dubbed a “rapid reset attack” — works by sending a request and then immediately cancelling it (a feature of HTTP/2). “This lets attackers skip waiting for responses, resulting in a more efficient attack,” Menscher explained.
Natalie Silva, lead security engineer at Immersive Labs, said this flaw’s impact to enterprise customers could be significant, and lead to prolonged downtime.
“It is crucial for organizations to apply the latest patches and updates from their web server vendors to mitigate this vulnerability and protect against such attacks,” Silva said. In this month’s Patch Tuesday release by Microsoft, they have released both an update to this vulnerability, as well as a temporary workaround should you not be able to patch immediately.”
Microsoft also patched zero-day bugs in Skype for Business (CVE-2023-41763) and Wordpad (CVE-2023-36563). The latter vulnerability could expose NTLM hashes, which are used for authentication in Windows environments.
“It may or may not be a coincidence that Microsoft announced last month that WordPad is no longer being updated, and will be removed in a future version of Windows, although no specific timeline has yet been given,” said Adam Barnett, lead software engineer at Rapid7. “Unsurprisingly, Microsoft recommends Word as a replacement for WordPad.”
Other notable bugs addressed by Microsoft include CVE-2023-35349, a remote code execution weakness in the Message Queuing (MSMQ) service, a technology that allows applications across multiple servers or hosts to communicate with each other. This vulnerability has earned a CVSS severity score of 9.8 (10 is the worst possible). Happily, the MSMQ service is not enabled by default in Windows, although Immersive Labs notes that Microsoft Exchange Server can enable this service during installation.
Speaking of Exchange, Microsoft also patched CVE-2023-36778, a vulnerability in all current versions of Exchange Server that could allow attackers to run code of their choosing. Rapid7’s Barnett said successful exploitation requires that the attacker be on the same network as the Exchange Server host, and use valid credentials for an Exchange user in a PowerShell session.

The U.S. government today announced a coordinated crackdown against QakBot, a complex malware family used by multiple cybercrime groups to lay the groundwork for ransomware infections. The international law enforcement operation involved seizing control over the botnet’s online infrastructure, and quietly removing the Qakbot malware from tens of thousands of infected Microsoft Windows computers.

In an international operation announced today dubbed “Duck Hunt,” the U.S. Department of Justice (DOJ) and Federal Bureau of Investigation (FBI) said they obtained court orders to remove Qakbot from infected devices, and to seize servers used to control the botnet.
“This is the most significant technological and financial operation ever led by the Department of Justice against a botnet,” said Martin Estrada, the U.S. attorney for the Southern District of California, at a press conference this morning in Los Angeles.
Estrada said Qakbot has been implicated in 40 different ransomware attacks over the past 18 months, intrusions that collectively cost victims more than $58 million in losses.
Emerging in 2007 as a banking trojan, QakBot (a.k.a. Qbot and Pinkslipbot) has morphed into an advanced malware strain now used by multiple cybercriminal groups to prepare newly compromised networks for ransomware infestations. QakBot is most commonly delivered via email phishing lures disguised as something legitimate and time-sensitive, such as invoices or work orders.
Don Alway, assistant director in charge of the FBI’s Los Angeles field office, said federal investigators gained access to an online panel that allowed cybercrooks to monitor and control the actions of the botnet. From there, investigators obtained court-ordered approval to instruct all infected systems to uninstall Qakbot and to disconnect themselves from the botnet, Alway said.
The DOJ says their access to the botnet’s control panel revealed that Qakbot had been used to infect more than 700,000 machines in the past year alone, including 200,000 systems in the United States.
Working with law enforcement partners in France, Germany, Latvia, the Netherlands, Romania and the United Kingdom, the DOJ said it was able to seize more than 50 Internet servers tied to the malware network, and nearly $9 million in ill-gotten cryptocurrency from QakBot’s cybercriminal overlords. The DOJ declined to say whether any suspects were questioned or arrested in connection with Qakbot, citing an ongoing investigation.
According to recent figures from the managed security firm Reliaquest, QakBot is by far the most prevalent malware “loader” — malicious software used to secure access to a hacked network and help drop additional malware payloads. Reliaquest says QakBot infections accounted for nearly one-third of all loaders observed in the wild during the first six months of this year.

Researchers at AT&T Alien Labs say the crooks responsible for maintaining the QakBot botnet have rented their creation to various cybercrime groups over the years. More recently, however, QakBot has been closely associated with ransomware attacks from Black Basta, a prolific Russian-language criminal group that was thought to have spun off from the Conti ransomware gang in early 2022.
Today’s operation is not the first time the U.S. government has used court orders to remotely disinfect systems compromised with malware. In May 2023, the DOJ quietly removed malware from computers around the world infected by the “Snake” malware, an even older malware family that has been tied to Russian intelligence agencies.
Documents published by the DOJ in support of today’s takedown state that beginning on Aug. 25, 2023, law enforcement gained access to the Qakbot botnet, redirected botnet traffic to and through servers controlled by law enforcement, and instructed Qakbot-infected computers to download a Qakbot Uninstall file that uninstalled Qakbot malware from the infected computer.
“The Qakbot Uninstall file did not remediate other malware that was already installed on infected computers,” the government explained. “Instead, it was designed to prevent additional Qakbot malware from being installed on the infected computer by untethering the victim computer from the Qakbot botnet.”
The DOJ said it also recovered more than 6.5 million stolen passwords and other credentials, and that it has shared this information with two websites that let users check to see if their credentials were exposed: Have I Been Pwned, and a “Check Your Hack” website erected by the Dutch National Police.

Microsoft Corp. today released software updates to quash 130 security bugs in its Windows operating systems and related software, including at least five flaws that are already seeing active exploitation. Meanwhile, Apple customers have their own zero-day woes again this month: On Monday, Apple issued (and then quickly pulled) an emergency update to fix a zero-day vulnerability that is being exploited on MacOS and iOS devices.
On July 10, Apple pushed a “Rapid Security Response” update to fix a code execution flaw in the Webkit browser component built into iOS, iPadOS, and macOS Ventura. Almost as soon as the patch went out, Apple pulled the software because it was reportedly causing problems loading certain websites. MacRumors says Apple will likely re-release the patches when the glitches have been addressed.
Launched in May, Apple’s Rapid Security Response updates are designed to address time-sensitive vulnerabilities, and this is the second month Apple has used it. July marks the sixth month this year that Apple has released updates for zero-day vulnerabilities — those that get exploited by malware or malcontents before there is an official patch available.
If you rely on Apple devices and don’t have automatic updates enabled, please take a moment to check the patch status of your various iDevices. The latest security update that includes the fix for the zero-day bug should be available in iOS/iPadOS 16.5.1, macOS 13.4.1, and Safari 16.5.2.
On the Windows side, there are at least four vulnerabilities patched this month that earned high CVSS (badness) scores and that are already being exploited in active attacks, according to Microsoft. They include CVE-2023-32049, which is a hole in Windows SmartScreen that lets malware bypass security warning prompts; and CVE-2023-35311 allows attackers to bypass security features in Microsoft Outlook.
The two other zero-day threats this month for Windows are both privilege escalation flaws. CVE-2023-32046 affects a core Windows component called MSHTML, which is used by Windows and other applications, like Office, Outlook and Skype. CVE-2023-36874 is an elevation of privilege bug in the Windows Error Reporting Service.
Many security experts expected Microsoft to address a fifth zero-day flaw — CVE-2023-36884 — a remote code execution weakness in Office and Windows.
“Surprisingly, there is no patch yet for one of the five zero-day vulnerabilities,” said Adam Barnett, lead software engineer at Rapid7. “Microsoft is actively investigating publicly disclosed vulnerability, and promises to update the advisory as soon as further guidance is available.”
Barnett notes that Microsoft links exploitation of this vulnerability with Storm-0978, the software giant’s name for a cybercriminal group based out of Russia that is identified by the broader security community as RomCom.
“Exploitation of CVE-2023-36884 may lead to installation of the eponymous RomCom trojan or other malware,” Barnett said. “[Microsoft] suggests that RomCom / Storm-0978 is operating in support of Russian intelligence operations. The same threat actor has also been associated with ransomware attacks targeting a wide array of victims.”
Microsoft’s advisory on CVE-2023-36884 is pretty sparse, but it does include a Windows registry hack that should help mitigate attacks on this vulnerability. Microsoft has also published a blog post about phishing campaigns tied to Storm-0978 and to the exploitation of this flaw.
Barnett said it’s while it’s possible that a patch will be issued as part of next month’s Patch Tuesday, Microsoft Office is deployed just about everywhere, and this threat actor is making waves.
“Admins should be ready for an out-of-cycle security update for CVE-2023-36884,” he said.
Microsoft also today released new details about how it plans to address the existential threat of malware that is cryptographically signed by…wait for it….Microsoft.
In late 2022, security experts at Sophos, Trend Micro and Cisco warned that ransomware criminals were using signed, malicious drivers in an attempt to evade antivirus and endpoint detection and response (EDR) tools.
In a blog post today, Sophos’s Andrew Brandt wrote that Sophos identified 133 malicious Windows driver files that were digitally signed since April 2021, and found 100 of those were actually signed by Microsoft. Microsoft said today it is taking steps to ensure those malicious driver files can no longer run on Windows computers.
As KrebsOnSecurity noted in last month’s story on malware signing-as-a-service, code-signing certificates are supposed to help authenticate the identity of software publishers, and provide cryptographic assurance that a signed piece of software has not been altered or tampered with. Both of these qualities make stolen or ill-gotten code-signing certificates attractive to cybercriminal groups, who prize their ability to add stealth and longevity to malicious software.
Dan Goodin at Ars Technica contends that whatever Microsoft may be doing to keep maliciously signed drivers from running on Windows is being bypassed by hackers using open source software that is popular with video game cheaters.
“The software comes in the form of two software tools that are available on GitHub,” Goodin explained. “Cheaters use them to digitally sign malicious system drivers so they can modify video games in ways that give the player an unfair advantage. The drivers clear the considerable hurdle required for the cheat code to run inside the Windows kernel, the fortified layer of the operating system reserved for the most critical and sensitive functions.”
Meanwhile, researchers at Cisco’s Talos security team found multiple Chinese-speaking threat groups have repurposed the tools—one apparently called “HookSignTool” and the other “FuckCertVerifyTimeValidity.”
“Instead of using the kernel access for cheating, the threat actors use it to give their malware capabilities it wouldn’t otherwise have,” Goodin said.
For a closer look at the patches released by Microsoft today, check out the always-thorough Patch Tuesday roundup from the SANS Internet Storm Center. And it’s not a bad idea to hold off updating for a few days until Microsoft works out any kinks in the updates: AskWoody.com usually has the lowdown on any patches that may be causing problems for Windows users.
And as ever, please consider backing up your system or at least your important documents and data before applying system updates. If you encounter any problems with these updates, please drop a note about it here in the comments.
The United Parcel Service (UPS) says fraudsters have been harvesting phone numbers and other information from its online shipment tracking tool in Canada to send highly targeted SMS phishing (a.k.a. “smishing”) messages that spoofed UPS and other top brands. The missives addressed recipients by name, included details about recent orders, and warned that those orders wouldn’t be shipped unless the customer paid an added delivery fee.
In a snail mail letter sent this month to Canadian customers, UPS Canada Ltd. said it is aware that some package recipients have received fraudulent text messages demanding payment before a package can be delivered, and that it has been working with partners in its delivery chain to try to understand how the fraud was occurring.
The recent letter from UPS about SMS phishers harvesting shipment details and phone numbers from its website.
“During that review, UPS discovered a method by which a person who searched for a particular package or misused a package look-up tool could obtain more information about the delivery, potentially including a recipient’s phone number,” the letter reads. “Because this information could be misused by third parties, including potentially in a smishing scheme, UPS has taken steps to limit access to that information.”
The written notice goes on to say UPS believes the data exposure “affected packages for a small group of shippers and some of their customers from February 1, 2022 to April 24, 2023.”
As early as April 2022, KrebsOnSecurity began receiving tips from Canadian readers who were puzzling over why they’d just received one of these SMS phishing messages that referenced information from a recent order they’d legitimately placed at an online retailer.
In March, 2023, a reader named Dylan from British Columbia wrote in to say he’d received one of these shipping fee scam messages not long after placing an order to buy gobs of building blocks directly from Lego.com. The message included his full name, phone number, and postal code, and urged him to click a link to mydeliveryfee-ups[.]info and pay a $1.55 delivery fee that was supposedly required to deliver his Legos.
“From searching the text of this phishing message, I can see that a lot of people have experienced this scam, which is more convincing because of the information the phishing text contains,” Dylan wrote. “It seems likely to me that UPS is leaking information somehow about upcoming deliveries.”
Josh is a reader who works for a company that ships products to Canada, and in early January 2023 he inquired whether there was any information about a breach at UPS Canada.
“We’ve seen many of our customers targeted with a fraudulent UPS text message scheme after placing an order,” Josh said. “A link is provided (often only after the customer responds to the text) which takes you to a captcha page, followed by a fraudulent payment collection page.”
Pivoting on the domain in the smishing message sent to Dylan shows the phishing domain shared an Internet host in Russia [91.215.85-166] with nearly two dozen other smishing related domains, including upsdelivery[.]info, legodelivery[.]info, adidascanadaltd[.]com, crocscanadafee[.]info, refw0234apple[.]info, vista-printcanada[.]info and telus-ca[.]info.
The inclusion of big-name brands in the domains of these UPS smishing campaigns suggests the perpetrators had the ability to focus their lookups on UPS customers who had recently ordered items from specific companies.
Attempts to visit these domains with a web browser failed, but loading them in a mobile device (or in my case, emulating a mobile device using a virtual machine and Developer Tools in Firefox) revealed the first stage of this smishing attack. As Josh mentioned, what first popped up was a CAPTCHA; after the visitor solved the CAPTCHA, they were taken through several more pages that requested the user’s full name, date of birth, credit card number, address, email and phone number.
A smishing website targeting Canadians who recently purchased from Adidas online. The site would only load in a mobile browser.
In April 2022, KrebsOnSecurity heard from Alex, the CEO of a technology company in Canada who asked to leave his last name out of this story. Alex reached out when he began receiving the smishing messages almost immediately after ordering two sets of Airpods directly from Apple’s website.
What puzzled Alex most was that he’d instructed Apple to send the Airpods as a gift to two different people, and less than 24 hours later the phone number he uses for his Apple account received two of the phishing messages, both of which contained salutations that included the names of the people for whom he’d bought Airpods.
“I’d put the recipient as different people on my team, but because it was my phone number on both orders I was the one getting the texts,” Alex explained. “That same day, I got text messages referring to me as two different people, neither of whom were me.”
Alex said he believes UPS Canada either doesn’t fully understand what happened yet, or it is being coy about what it knows. He said the wording of UPS’s response misleadingly suggests the smishing attacks were somehow the result of hackers randomly looking up package information via the company’s tracking website.
Alex said it’s likely that whoever is responsible figured out how to query the UPS Canada website for only pending orders from specific brands, perhaps by exploiting some type of application programming interface (API) that UPS Canada makes or made available to its biggest retail partners.
“It wasn’t like I put the order through [on Apple.ca] and some days or weeks later I got a targeted smishing attack,” he said. “It was more or less the same day. And it was as if [the phishers] were being notified the order existed.”
The letter to UPS Canada customers does not mention whether any other customers in North America were affected, and it remains unclear whether any UPS customers outside of Canada may have been targeted.
In a statement provided to KrebsOnSecurity, Sandy Springs, Ga. based UPS [NYSE:UPS] said the company has been working with partners in the delivery chain to understand how that fraud was being perpetrated, as well as with law enforcement and third-party experts to identify the cause of this scheme and to put a stop to it.
“Law enforcement has indicated that there has been an increase in smishing impacting a number of shippers and many different industries,” reads an email from Brian Hughes, director of financial and strategy communications at UPS.
“Out of an abundance of caution, UPS is sending privacy incident notification letters to individuals in Canada whose information may have been impacted,” Hughes said. “We encourage our customers and general consumers to learn about the ways they can stay protected against attempts like this by visiting the UPS Fight Fraud website.”
The U.S. government agency in charge of improving the nation’s cybersecurity posture is ordering all federal agencies to take new measures to restrict access to Internet-exposed networking equipment. The directive comes amid a surge in attacks targeting previously unknown vulnerabilities in widely used security and networking appliances.
Under a new order from the Cybersecurity and Infrastructure Security Agency (CISA), federal agencies will have 14 days to respond to any reports from CISA about misconfigured or Internet-exposed networking equipment. The directive applies to any networking devices — such as firewalls, routers and load balancers — that allow remote authentication or administration.
The order requires federal departments to limit access so that only authorized users on an agency’s local or internal network can reach the management interfaces of these devices. CISA’s mandate follows a slew of recent incidents wherein attackers exploited zero-day flaws in popular networking products to conduct ransomware and cyber espionage attacks on victim organizations.
Earlier today, incident response firm Mandiant revealed that since at least October 2022, Chinese cyber spies have been exploiting a zero-day vulnerability in many email security gateway (ESG) appliances sold by California-based Barracuda Networks to hoover up email from organizations using these devices.
Barracuda was alerted to the exploitation of a zero-day in its products in mid-May, and two days later the company pushed a security update to address the flaw in all affected devices. But last week, Barracuda took the highly unusual step of offering to replace compromised ESGs, evidently in response to malware that altered the systems in such a fundamental way that they could no longer be secured remotely with software updates.
According to Mandiant, a previously unidentified Chinese hacking group was responsible for exploiting the Barracuda flaw, and appeared to be searching through victim organization email records for accounts “belonging to individuals working for a government with political or strategic interest to [China] while this victim government was participating in high-level, diplomatic meetings with other countries.”
When security experts began raising the alarm about a possible zero-day in Barracuda’s products, the Chinese hacking group altered their tactics, techniques and procedures (TTPs) in response to Barracuda’s efforts to contain and remediate the incident, Mandiant found.
Mandiant said the attackers will continue to change their tactics and malware, “especially as network defenders continue to take action against this adversary and their activity is further exposed by the infosec community.”
Meanwhile, this week we learned more details about the ongoing exploitation of a zero-day flaw in a broad range of virtual private networking (VPN) products made by Fortinet — devices many organizations rely on to facilitate remote network access for employees.
On June 11, Fortinet released a half-dozen security updates for its FortiOS firmware, including a weakness that researchers said allows an attacker to run malware on virtually any Fortinet SSL VPN appliance. The researchers found that just being able to reach the management interface for a vulnerable Fortinet SSL VPN appliance was enough to completely compromise the devices.
“This is reachable pre-authentication, on every SSL VPN appliance,” French vulnerability researcher Charles Fol tweeted. “Patch your #Fortigate.”
In details published on June 12, Fortinet confirmed that one of the vulnerabilities (CVE-2023-27997) is being actively exploited. The company said it discovered the weakness in an internal code audit that began in January 2023 — when it learned that Chinese hackers were exploiting a different zero-day flaw in its products.
Shodan.io, the search engine made for finding Internet of Things devices, reports that there are currently more than a half-million vulnerable Fortinet devices reachable via the public Internet.
The new cybersecurity directive from CISA orders agencies to remove any networking device management interfaces from the internet by making them only accessible from an internal enterprise network (CISA recommends an isolated management network). CISA also says agencies should “deploy capabilities, as part of a Zero Trust Architecture, that enforce access control to the interface through a policy enforcement point separate from the interface itself (preferred action).”
Security experts say CISA’s directive highlights the reality that cyberspies and ransomware gangs are making it increasingly risky for organizations to expose any devices to the public Internet, because these groups have strong incentives to probe such devices for previously unknown security vulnerabilities.
The most glaring example of this dynamic can be seen in the frequency with which ransomware groups have discovered and pounced on zero-day flaws in widely-used file transfer applications. One ransomware gang in particular — Cl0p — has repeatedly exploited zero day bugs in various file transfer appliances to extort tens of millions of dollars from hundreds of ransomware victims.
On February 2, KrebsOnSecurity broke the news that attackers were exploiting a zero-day vulnerability in the GoAnywhere file transfer appliance by Fortra. By the time security updates were available to fix the vulnerability, Cl0p had already used it to steal data from more than a hundred organizations running Fortra’s appliance.
According to CISA, on May 27, Cl0p began exploiting a previously unknown flaw in MOVEit Transfer, a popular Internet-facing file transfer application. MOVEit parent Progress Software has since released security updates to address the weakness, but Cl0p claims to have already used it to compromise hundreds of victim organizations. TechCrunch has been tracking the fallout from victim organizations, which range from banks and insurance providers to universities and healthcare entities.
The always on-point weekly security news podcast Risky Business has recently been urging organizations to jettison any and all FTP appliances, noting that Cl0p (or another crime gang) is likely to visit the same treatment on other FTP appliance vendors.
But that sound advice doesn’t exactly scale for mid-tier networking devices like Barracuda ESGs or Fortinet SSL VPNs, which are particularly prominent in small to mid-sized organizations.
“It’s not like FTP services, you can’t tell an enterprise [to] turn off the VPN [because] the productivity hit of disconnecting the VPN is terminal, it’s a non-starter,” Risky Business co-host Adam Boileau said on this week’s show. “So how to mitigate the impact of having to use a domain-joined network appliance at the edge of your network that is going to get zero-day in it? There’s no good answer.”
Risky Business founder Patrick Gray said the COVID-19 pandemic breathed new life into entire classes of networking appliances that rely on code which was never designed with today’s threat models in mind.
“In the years leading up to the pandemic, the push towards identity-aware proxies and zero trust everything and moving away from this type of equipment was gradual, but it was happening,” Gray said. “And then COVID-19 hit and everybody had to go work from home, and there really was one option to get going quickly — which was to deploy VPN concentrators with enterprise features.”
Gray said the security industry had been focused on building the next generation of remote access tools that are more security-hardened, but when the pandemic hit organizations scrambled to cobble together whatever they could.
“The only stuff available in the market was all this old crap that is not QA’d properly, and every time you shake them CVEs fall out,” Gray remarked, calling the pandemic, “a shot in the arm” to companies like Fortinet and Barracuda.
“They sold so many VPNs through the pandemic and this is the hangover,” Gray said. “COVID-19 extended the life of these companies and technologies, and that’s unfortunate.”
