When KrebsOnSecurity broke the news on Oct. 20, 2023 that identity and authentication giant Okta had suffered a breach in its customer support department, Okta said the intrusion allowed hackers to steal sensitive data from fewer than one percent of its 18,000+ customers. But today, Okta revised that impact statement, saying the attackers also stole the name and email address for nearly all of its customer support users.
Okta acknowledged last month that for several weeks beginning in late September 2023, intruders had access to its customer support case management system. That access allowed the hackers to steal authentication tokens from some Okta customers, which the attackers could then use to make changes to customer accounts, such as adding or modifying authorized users.
In its initial incident reports about the breach, Okta said the hackers gained unauthorized access to files inside Okta’s customer support system associated with 134 Okta customers, or less than 1% of Okta’s customer base.
But in an updated statement published early this morning, Okta said it determined the intruders also stole the names and email addresses of all Okta customer support system users.
“All Okta Workforce Identity Cloud (WIC) and Customer Identity Solution (CIS) customers are impacted except customers in our FedRamp High and DoD IL4 environments (these environments use a separate support system NOT accessed by the threat actor),” Okta’s advisory states. “The Auth0/CIC support case management system was also not impacted by this incident.”
Okta said that for nearly 97 percent of users, the only contact information exposed was full name and email address. That means about three percent of Okta customer support accounts had one or more of the following data fields exposed (in addition to email address and name): last login; username; phone number; SAML federation ID; company name; job role; user type; date of last password change or reset.
Okta notes that a large number of the exposed accounts belong to Okta administrators — IT people responsible for integrating Okta’s authentication technology inside customer environments — and that these individuals should be on guard for targeted phishing attacks.
“Many users of the customer support system are Okta administrators,” Okta pointed out. “It is critical that these users have multi-factor authentication (MFA) enrolled to protect not only the customer support system, but also to secure access to their Okta admin console(s).”
While it may seem completely bonkers that some companies allow their IT staff to operate company-wide authentication systems using an Okta administrator account that isn’t protected with MFA, Okta said fully six percent of its customers (more than 1,000) persist in this dangerous practice.
In a previous disclosure on Nov. 3, Okta blamed the intrusion on an employee who saved the credentials for a service account in Okta’s customer support infrastructure to their personal Google account, and said it was likely those credentials were stolen when the employee’s personal device using the same Google account was compromised.
Unlike standard user accounts, which are accessed by humans, service accounts are mostly reserved for automating machine-to-machine functions, such as performing data backups or antivirus scans every night at a particular time. For this reason, they can’t be locked down with multifactor authentication the way user accounts can.
Dan Goodin over at Ars Technica reckons this explains why MFA wasn’t set up on the compromised Okta service account. But as he rightly points out, if a transgression by a single employee breaches your network, you’re doing it wrong.
“Okta should have put access controls in place besides a simple password to limit who or what could log in to the service account,” Goodin wrote on Nov. 4. “One way of doing this is to put a limit or conditions on the IP addresses that can connect. Another is to regularly rotate access tokens used to authenticate to service accounts. And, of course, it should have been impossible for employees to be logged in to personal accounts on a work machine. These and other precautions are the responsibility of senior people inside Okta.”
Goodin suggested that people who want to delve further into various approaches for securing service accounts should read this thread on Mastodon.
“A fair number of the contributions come from security professionals with extensive experience working in sensitive cloud environments,” Goodin wrote.
One of the cybercrime underground’s more active sellers of Social Security numbers, background and credit reports has been pulling data from hacked accounts at the U.S. consumer data broker USinfoSearch, KrebsOnSecurity has learned.
Since at least February 2023, a service advertised on Telegram called USiSLookups has operated an automated bot that allows anyone to look up the SSN or background report on virtually any American. For prices ranging from $8 to $40 and payable via virtual currency, the bot will return detailed consumer background reports automatically in just a few moments.
USiSLookups is the project of a cybercriminal who uses the nicknames JackieChan/USInfoSearch, and the Telegram channel for this service features a small number of sample background reports, including that of President Joe Biden, and podcaster Joe Rogan. The data in those reports includes the subject’s date of birth, address, previous addresses, previous phone numbers and employers, known relatives and associates, and driver’s license information.
JackieChan’s service abuses the name and trademarks of Columbus, OH based data broker USinfoSearch, whose website says it provides “identity and background information to assist with risk management, fraud prevention, identity and age verification, skip tracing, and more.”
“We specialize in non-FCRA data from numerous proprietary sources to deliver the information you need, when you need it,” the company’s website explains. “Our services include API-based access for those integrating data into their product or application, as well as bulk and batch processing of records to suit every client.”
As luck would have it, my report was also listed in the Telegram channel for this identity fraud service, presumably as a teaser for would-be customers. On October 19, 2023, KrebsOnSecurity shared a copy of this file with the real USinfoSearch, along with a request for information about the provenance of the data.
USinfoSearch said it would investigate the report, which appears to have been obtained on or before June 30, 2023. On Nov. 9, 2023, Scott Hostettler, general manager of USinfoSearch parent Martin Data LLC shared a written statement about their investigation that suggested the ID theft service was trying to pass off someone else’s consumer data as coming from USinfoSearch:
Regarding the Telegram incident, we understand the importance of protecting sensitive information and upholding the trust of our users is our top priority. Any allegation that we have provided data to criminals is in direct opposition to our fundamental principles and the protective measures we have established and continually monitor to prevent any unauthorized disclosure. Because Martin Data has a reputation for high-quality data, thieves may steal data from other sources and then disguise it as ours. While we implement appropriate safeguards to guarantee that our data is only accessible by those who are legally permitted, unauthorized parties will continue to try to access our data. Thankfully, the requirements needed to pass our credentialing process is tough even for established honest companies.
USinfoSearch’s statement did not address any questions put to the company, such as whether it requires multi-factor authentication for customer accounts, or whether my report had actually come from USinfoSearch’s systems.
After much badgering, on Nov. 21 Hostettler acknowledged that the USinfoSearch identity fraud service on Telegram was in fact pulling data from an account belonging to a vetted USinfoSearch client.
“I do know 100% that my company did not give access to the group who created the bots, but they did gain access to a client,” Hostettler said of the Telegram-based identity fraud service. “I apologize for any inconvenience this has caused.”
Hostettler said USinfoSearch heavily vets any new potential clients, and that all users are required to undergo a background check and provide certain documents. Even so, he said, several fraudsters each month present themselves as credible business owners or C-level executives during the credentialing process, completing the application and providing the necessary documentation to open a new account.
“The level of skill and craftsmanship demonstrated in the creation of these supporting documents is incredible,” Hostettler said. “The numerous licenses provided appear to be exact replicas of the original document. Fortunately, I’ve discovered several methods of verification that do not rely solely on those documents to catch the fraudsters.”
“These people are unrelenting, and they act without regard for the consequences,” Hostettler continued. “After I deny their access, they will contact us again within the week using the same credentials. In the past, I’ve notified both the individual whose identity is being used fraudulently and the local police. Both are hesitant to act because nothing can be done to the offender if they are not apprehended. That is where most attention is needed.”
JackieChan is most active on Telegram channels focused on “SIM swapping,” which involves bribing or tricking mobile phone company employees into redirecting a target’s phone number to a device the attackers control. SIM swapping allows crooks to temporarily intercept the target’s text messages and phone calls, including any links or one-time codes for authentication that are delivered via SMS.
Reached on Telegram, JackieChan said most of his clients hail from the criminal SIM swapping world, and that the bulk of his customers use his service via an application programming interface (API) that allows customers to integrate the lookup service with other web-based services, databases, or applications.
“Sim channels is where I get most of my customers,” JackieChan told KrebsOnSecurity. “I’m averaging around 100 lookups per day on the [Telegram] bot, and around 400 per day on the API.”
JackieChan claims his USinfoSearch bot on Telegram abuses stolen credentials needed to access an API used by the real USinfoSearch, and that his service was powered by USinfoSearch account credentials that were stolen by malicious software tied to a botnet that he claims to have operated for some time.
This is not the first time USinfoSearch has had trouble with identity thieves masquerading as legitimate customers. In 2013, KrebsOnSecurity broke the news that an identity fraud service in the underground called “SuperGet[.]info” was reselling access to personal and financial data on more than 200 million Americans that was obtained via the big-three credit bureau Experian.
The consumer data resold by Superget was not obtained directly from Experian, but rather via USinfoSearch. At the time, USinfoSearch had a contractual agreement with a California company named Court Ventures, whereby customers of Court Ventures had access to the USinfoSearch data, and vice versa.
When Court Ventures was purchased by Experian in 2012, the proprietor of SuperGet — a Vietnamese hacker named Hieu Minh Ngo who had impersonated an American private investigator — was grandfathered in as a client. The U.S. Secret Service agent who oversaw Ngo’s capture, extradition, prosecution and rehabilitation told KrebsOnSecurity he’s unaware of any other cybercriminal who has caused more material financial harm to more Americans than Ngo.
JackieChan also sells access to hacked email accounts belonging to law enforcement personnel in the United States and abroad. Hacked police department emails can come in handy for ID thieves trying to pose as law enforcement officials who wish to purchase consumer data from platforms like USinfoSearch. Hence, Mr. Hostettler’s ongoing battle with fraudsters seeking access to his company’s service.
These police credentials are mainly marketed to criminals seeking fraudulent “Emergency Data Requests,” wherein crooks use compromised government and police department email accounts to rapidly obtain customer account data from mobile providers, ISPs and social media companies.
Normally, these companies will require law enforcement officials to supply a subpoena before turning over customer or user records. But EDRs allow police to bypass that process by attesting that the information sought is related to an urgent matter of life and death, such as an impending suicide or terrorist attack.
In response to an alarming increase in the volume of fraudulent EDRs, many service providers have chosen to require all EDRs be processed through a service called Kodex, which seeks to filter EDRs based on the reputation of the law enforcement entity requesting the information, and other attributes of the requestor.
For example, if you want to send an EDR to Coinbase or Twilio, you’ll first need to have valid law enforcement credentials and create an account at the Kodex online portal at these companies. However, Kodex may still throttle or block any requests from any accounts if they set off certain red flags.
Within their own separate Kodex portals, Twilio can’t see requests submitted to Coinbase, or vice versa. But each can see if a law enforcement entity or individual tied to one of their own requests has ever submitted a request to a different Kodex client, and then drill down further into other data about the submitter, such as Internet address(es) used, and the age of the requestor’s email address.
In August, JackieChan was advertising a working Kodex account for sale on the cybercrime channels, including redacted screenshots of the Kodex account dashboard as proof of access.
Kodex co-founder Matt Donahue told KrebsOnSecurity his company immediately detected that the law enforcement email address used to create the Kodex account pictured in JackieChan’s ad was likely stolen from a police officer in India. One big tipoff, Donahue said, was that the person creating the account did so using an Internet address in Brazil.
“There’s a lot of friction we can put in the way for illegitimate actors,” Donahue said. “We don’t let people use VPNs. In this case we let them in to honeypot them, and that’s how they got that screenshot. But nothing was allowed to be transmitted out from that account.”
Massive amounts of data about you and your personal history are available from USinfoSearch and dozens of other data brokers that acquire and sell “non-FCRA” data — i.e., consumer data that cannot be used for the purposes of determining one’s eligibility for credit, insurance, or employment.
Anyone who works in or adjacent to law enforcement is eligible to apply for access to these data brokers, which often market themselves to police departments and to “skip tracers,” essentially bounty hunters hired to locate others in real life — often on behalf of debt collectors, process servers or a bail bondsman.
There are tens of thousands of police jurisdictions around the world — including roughly 18,000 in the United States alone. And the harsh reality is that all it takes for hackers to apply for access to data brokers (and abuse the EDR process) is illicit access to a single police email account.
The trouble is, compromised credentials to law enforcement email accounts show up for sale with alarming frequency on the Telegram channels where JackieChan and their many clients reside. Indeed, Donahue said Kodex so far this year has identified attempted fake EDRs coming from compromised email accounts for police departments in India, Italy, Thailand and Turkey.

In the summer of 2022, KrebsOnSecurity documented the plight of several readers who had their accounts at big-three consumer credit reporting bureau Experian hijacked after identity thieves simply re-registered the accounts using a different email address. Sixteen months later, Experian clearly has not addressed this gaping lack of security. I know that because my account at Experian was recently hacked, and the only way I could recover access was by recreating the account.
Entering my SSN and birthday at Experian showed my identity was tied to an email address I did not authorize.
I recently ordered a copy of my credit file from Experian via annualcreditreport.com, but as usual Experian declined to provide it, saying they couldn’t verify my identity. Attempts to log in to my account directly at Experian.com also failed; the site said it didn’t recognize my username and/or password.
A request for my Experian account username required my full Social Security number and date of birth, after which the website displayed portions of an email address I never authorized and did not recognize (the full address was redacted by Experian).
I immediately suspected that Experian was still allowing anyone to recreate their credit file account using the same personal information but a different email address, a major authentication failure that was explored in last year’s story, Experian, You Have Some Explaining to Do. So once again I sought to re-register as myself at Experian.
The homepage said I needed to provide a Social Security number and mobile phone number, and that I’d soon receive a link that I should click to verify myself. The site claims that the phone number you provide will be used to help validate your identity. But it appears you could supply any phone number in the United States at this stage in the process, and Experian’s website would not balk. Regardless, users can simply skip this step by selecting the option to “Continue another way.”
Experian then asks for your full name, address, date of birth, Social Security number, email address and chosen password. After that, they require you to successfully answer between three to five multiple-choice security questions whose answers are very often based on public records. When I recreated my account this week, only two of the five questions pertained to my real information, and both of those questions concerned street addresses we’ve previously lived at — information that is just a Google search away.
Assuming you sail through the multiple-choice questions, you’re prompted to create a 4-digit PIN and provide an answer to one of several pre-selected challenge questions. After that, your new account is created and you’re directed to the Experian dashboard, which allows you to view your full credit file, and freeze or unfreeze it.
At this point, Experian will send a message to the old email address tied to the account, saying certain aspects of the user profile have changed. But this message isn’t a request seeking verification: It’s just a notification from Experian that the account’s user data has changed, and the original user is offered zero recourse here other than to a click a link to log in at Experian.com.
If you don’t have an Experian account, it’s a good idea to create one. Because at least then you will receive one of these emails when someone hijacks your credit file at Experian.
And of course, a user who receives one of these notices will find that the credentials to their Experian account no longer work. Nor do their PIN or account recovery question, because those have been changed also. Your only option at this point is recreate your account at Experian and steal it back from the ID thieves!
In contrast, if you try to modify an existing account at either of the other two major consumer credit reporting bureaus — Equifax or TransUnion — they will ask you to enter a code sent to the email address or phone number on file before any changes can be made.
Reached for comment, Experian declined to share the full email address that was added without authorization to my credit file.
“To ensure the protection of consumers’ identities and information, we have implemented a multi-layered security approach, which includes passive and active measures, and are constantly evolving,” Experian spokesperson Scott Anderson said in an emailed statement. “This includes knowledge-based questions and answers, and device possession and ownership verification processes.”
Anderson said all consumers have the option to activate a multi-factor authentication method that’s requested each time they log in to their account. But what good is multi-factor authentication if someone can simply recreate your account with a new phone number and email address?
Several readers who spotted my rant about Experian on Mastodon earlier this week responded to a request to validate my findings. The Mastodon user @Jackerbee is a reader from Michican who works in the biotechnology industry. @Jackerbee said when prompted by Experian to provide his phone number and the last four digits of his SSN, he chose the option to “manually enter my information.”
“I put my second phone number and the new email address,” he explained. “I received a single email in my original account inbox that said they’ve updated my information after I ‘signed up.’ No verification required from the original email address at any point. I also did not receive any text alerts at the original phone number. The especially interesting and egregious part is that when I sign in, it does 2FA with the new phone number.”
The Mastodon user PeteMayo said they recreated their Experian account twice this week, the second time by supplying a random landline number.
“The only difference: it asked me FIVE questions about my personal history (last time it only asked three) before proclaiming, ‘Welcome back, Pete!,’ and granting full access,” @PeteMayo wrote. “I feel silly saving my password for Experian; may as well just make a new account every time.”
I was fortunate in that whoever hijacked my account did not also thaw my credit freeze. Or if they did, they politely froze it again when they were done. But I fully expect my Experian account will be hijacked yet again unless Experian makes some important changes to its authentication process.
It boggles the mind that these fundamental authentication weaknesses have been allowed to persist for so long at Experian, which already has a horrible track record in this regard.
In December 2022, KrebsOnSecurity alerted Experian that identity thieves had worked out a remarkably simple way to bypass its security and access any consumer’s full credit report — armed with nothing more than a person’s name, address, date of birth, and Social Security number. Experian fixed the glitch, and acknowledged that it persisted for nearly seven weeks, between Nov. 9, 2022 and Dec. 26, 2022.
In April 2021, KrebsOnSecurity revealed how identity thieves were exploiting lax authentication on Experian’s PIN retrieval page to unfreeze consumer credit files. In those cases, Experian failed to send any notice via email when a freeze PIN was retrieved, nor did it require the PIN to be sent to an email address already associated with the consumer’s account.
A few days after that April 2021 story, KrebsOnSecurity broke the news that an Experian API was exposing the credit scores of most Americans.

Last week, KrebsOnSecurity broke the news that one of the largest cybercrime services for laundering stolen merchandise was hacked recently, exposing its internal operations, finances and organizational structure. In today’s Part II, we’ll examine clues about the real-life identity of “Fearlless,” the nickname chosen by the proprietor of the SWAT USA Drops service.
Based in Russia, SWAT USA recruits people in the United States to reship packages containing pricey electronics that are purchased with stolen credit cards. As detailed in this Nov. 2 story, SWAT currently employs more than 1,200 U.S. residents, all of whom will be cut loose without a promised payday at the end of their first month reshipping stolen goods.
The current co-owner of SWAT, a cybercriminal who uses the nickname “Fearlless,” operates primarily on the cybercrime forum Verified. This Russian-language forum has tens of thousands of members, and it has suffered several hacks that exposed more than a decade’s worth of user data and direct messages.
January 2021 posts on Verified show that Fearlless and his partner Universalo purchased the SWAT reshipping business from a Verified member named SWAT, who’d been operating the service for years. SWAT agreed to transfer the business in exchange for 30 percent of the net profit over the ensuing six months.
Cyber intelligence firm Intel 471 says Fearlless first registered on Verified in February 2013. The email address Fearlless used on Verified leads nowhere, but a review of Fearlless’ direct messages on Verified indicates this user originally registered on Verified a year earlier as a reshipping vendor, under the alias “Apathyp.”
There are two clues supporting the conclusion that Apathyp and Fearlless are the same person. First, the Verified administrators warned Apathyp he had violated the forum’s rules barring the use of multiple accounts by the same person, and that Verified’s automated systems had detected that Apathyp and Fearlless were logging in from the same device. Second, in his earliest private messages on Verified, Fearlless told others to contact him on an instant messenger address that Apathyp had claimed as his.
Intel 471 says Apathyp registered on Verified using the email address triploo@mail.ru. A search on that email address at the breach intelligence service Constella Intelligence found that a password commonly associated with it was “niceone.” But the triploo@mail.ru account isn’t connected to much else that’s interesting except a now-deleted account at Vkontakte, the Russian answer to Facebook.
However, in Sept. 2020, Apathyp sent a private message on Verified to the owner of a stolen credit card shop, saying his credentials no longer worked. Apathyp told the proprietor that his chosen password on the service was “12Apathy.”
A search on that password at Constella reveals it was used by just four different email addresses, two of which are particularly interesting: gezze@yandex.ru and gezze@mail.ru. Constella discovered that both of these addresses were previously associated with the same password as triploo@mail.ru — “niceone,” or some variation thereof.
Constella found that years ago gezze@mail.ru was used to create a Vkontakte account under the name Ivan Sherban (former password: “12niceone“) from Magnitogorsk, an industrial city in the southern region of Russia. That same email address is now tied to a Vkontakte account for an Ivan Sherban who lists his home as Saint Petersburg, Russia. Sherban’s profile photo shows a heavily tattooed, muscular and recently married individual with his beautiful new bride getting ready to drive off in a convertible sports car.
A pivotal clue for validating the research into Apathyp/Fearlless came from the identity intelligence firm myNetWatchman, which found that gezze@mail.ru at one time used the passwords “геззи1991” (gezze1991) and “gezze18081991.”
Care to place a wager on when Vkontakte says is Mr. Sherban’s birthday? Ten points if you answered August 18 (18081991).
Mr. Sherban did not respond to multiple requests for comment.
The top-level domain for the United States — .US — is home to thousands of newly-registered domains tied to a malicious link shortening service that facilitates malware and phishing scams, new research suggests. The findings come close on the heels of a report that identified .US domains as among the most prevalent in phishing attacks over the past year.
Researchers at Infoblox say they’ve been tracking what appears to be a three-year-old link shortening service that is catering to phishers and malware purveyors. Infoblox found the domains involved are typically three to seven characters long, and hosted on bulletproof hosting providers that charge a premium to ignore any abuse or legal complaints. The short domains don’t host any content themselves, but are used to obfuscate the real address of landing pages that try to phish users or install malware.
A graphic describing the operations of a malicious link shortening service that Infoblox has dubbed “Prolific Puma.”
Infoblox says it’s unclear how the phishing and malware landing pages tied to this service are being initially promoted, although they suspect it is mainly through scams targeting people on their phones via SMS. A new report says the company mapped the contours of this link shortening service thanks in part to pseudo-random patterns in the short domains, which all appear on the surface to be a meaningless jumble of letters and numbers.
“This came to our attention because we have systems that detect registrations that use domain name generation algorithms,” said Renee Burton, head of threat intelligence at Infoblox. “We have not found any legitimate content served through their shorteners.”
Infoblox determined that until May 2023, domains ending in .info accounted for the bulk of new registrations tied to the malicious link shortening service, which Infoblox has dubbed “Prolific Puma.” Since then, they found that whoever is responsible for running the service has used .US for approximately 55 percent of the total domains created, with several dozen new malicious .US domains registered daily.
.US is overseen by the National Telecommunications and Information Administration (NTIA), an executive branch agency of the U.S. Department of Commerce. But Uncle Sam has long outsourced the management of .US to various private companies, which have gradually allowed the United States’s top-level domain to devolve into a cesspool of phishing activity.
Or so concludes The Interisle Consulting Group, which gathers phishing data from multiple industry sources and publishes an annual report on the latest trends. As far back as 2018, Interisle found .US domains were the worst in the world for spam, botnet (attack infrastructure for DDOS etc.) and illicit or harmful content.
Interisle’s newest study examined six million phishing reports between May 1, 2022 and April 30, 2023, and identified approximately 30,000 .US phishing domains. Interisle found significant numbers of .US domains were registered to attack some of the United States’ most prominent companies, including Bank of America, Amazon, Apple, AT&T, Citi, Comcast, Microsoft, Meta, and Target. Others were used to impersonate or attack U.S. government agencies.
Under NTIA regulations, domain registrars processing .US domain registrations must take certain steps (PDF) to verify that those customers actually reside in the United States, or else own organizations based in the U.S. However, if one registers a .US domain through GoDaddy — the largest domain registrar and the current administrator of the .US contract — the way one “proves” their U.S. nexus is simply by choosing from one of three pre-selected affirmative responses.
In an age when most domain registrars are automatically redacting customer information from publicly accessible registration records to avoid running afoul of European privacy laws, .US has remained something of an outlier because its charter specifies that all registration records be made public. However, Infoblox said it found more than 2,000 malicious link shortener domains ending in .US registered since October 2023 through NameSilo that have somehow subverted the transparency requirements for the usTLD and converted to private registrations.
“Through our own experience with NameSilo, it is not possible to select private registration for domains in the usTLD through their interface,” Infoblox wrote. “And yet, it was done. Of the total domains with private records, over 99% were registered with NameSilo. At this time, we are not able to explain this behavior.”
NameSilo CEO Kristaps Ronka said the company actively responds to reports about abusive domains, but that it hasn’t seen any abuse reports related to Infoblox’s findings.
“We take down hundreds to thousands of domains, lots of them proactively to combat abuse,” Ronka said. “Our current abuse rate on abuseIQ for example is currently at 0%. AbuseIQ receives reports from countless sources and we are yet to see these ‘Puma’ abuse reports.”
Experts who track domains associated with malware and phishing say even phony information supplied at registration is useful in identifying potentially malicious or phishous domains before they can be used for abuse.
For example, when it was registered through NameSilo in July 2023, the domain 1ox[.]us — like thousands of others — listed its registrant as “Leila Puma” at a street address in Poland, and the email address blackpumaoct33@ukr.net. But according to DomainTools.com, on Oct. 1, 2023 those records were redacted and hidden by NameSilo.
Infoblox notes that the username portion of the email address appears to be a reference to the song October 33 by the Black Pumas, an Austin, Texas based psychedelic soul band. The Black Pumas aren’t exactly a household name, but they did recently have a popular Youtube video that featured a cover of the Kinks song “Strangers,” which included an emotional visual narrative about Ukrainians seeking refuge from the Russian invasion, titled “Ukraine Strangers.” Also, Leila Puma’s email address is at a Ukrainian email provider.
DomainTools shows that hundreds of other malicious domains tied to Prolific Puma previously were registered through NameCheap to a “Josef Bakhovsky” at a different street address in Poland. According to ancestry.com, the anglicized version of this surname — Bakovski — is the traditional name for someone from Bakowce, which is now known as Bakivtsi and is in Ukraine.
This possible Polish and/or Ukrainian connection may or may not tell us something about the “who” behind this link shortening service, but those details are useful for identifying and grouping these malicious short domains. However, even this meager visibility into .US registration data is now under threat.
The NTIA recently published a proposal that would allow registrars to redact all registrant data from WHOIS registration records for .US domains. A broad array of industry groups have filed comments opposing the proposed changes, saying they threaten to remove the last vestiges of accountability for a top-level domain that is already overrun with cybercrime activity.
Infoblox’s Burton says Prolific Puma is remarkable because they’ve been able to facilitate malicious activities for years while going largely unnoticed by the security industry.
“This exposes how persistent the criminal economy can be at a supply chain level,” Burton said. “We’re always looking at the end malware or phishing page, but what we’re finding here is that there’s this middle layer of DNS threat actors persisting for years without notice.”
Infoblox’s full report on Prolific Puma is here.
