ID Theft Service Resold Access to USInfoSearch Data

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.”

SIM SWAPPER’S DELIGHT

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.

REAL POLICE, FAKE EDRS

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.

Telegram – What Parents Need To Know Now

If you hadn’t heard of Telegram till 2021 then you wouldn’t be alone. This relatively unknown messaging and social media platform has risen from relative anonymity to become one of the biggest players in the ‘secret messaging’ business in less than a year. When What’s App changed its terms of usage in early 2021 and informed users that their data would be shared with their new parent Facebook, many ‘jumped ship’ in search of a less intrusive messaging option. But it was Facebook’s six-hour outage in early October that really made Telegram an enticing option. On that same day, Telegram gained a record 70 million users. 

According to Statista, Telegram is now the 10th most popular social media platform worldwide, coming in ahead of Snapchat, Pinterest, and even Twitter! So, as Telegram’s popularity continues to grow, it’s highly likely that your kids will be soon giving it a try if they haven’t already! So, how does it work? Is it safe? And, should you intervene. Here’s what you need to know… 

About Telegram 

Although many of us first heard about Telegram this year, it has in fact been around since 2013. Founded by Russian brothers Pavel and Nikolai Durov, Telegram was founded as part of their efforts to offer a forum for free speech online after their first social networking site, known as VK, was taken over by the Russian Government.  

Widely considered to be a Russian ‘Mark Zuckerberg’, VK made Pavel a billionaire. Pavel claims he was pushed out for refusing to provide VK data to the Russian government and shut down anti-corruption advocates. He has since cut ties with VK and moved to Germany. Telegram was last reported to be located in Dubai. 

How Does It Work? 

All you need is the Telegram app and a mobile phone number to start your Telegram account and yes, it works across both the Apple and Android platforms. Although it was started primarily as a messaging app, it has evolved into a social network that can be used to build groups around common interests. Both public and private groups can be set up as well as channels. It is also possible to search for people located close to you. And if you love stickers then you’ll love Telegram. Many consider it to have the best range of any messaging app! 

Is It Safe? 

Right from the start, Telegram has positioned itself as an app committed to private and secure messaging. However, the fact that end-to-end encryption is not automatically used on messages sent in Telegram means it is not as ‘secure’ as privacy focussed messaging platforms such as Signal which offer end-to-end encryption for all communication.  

It is important to note that Telegram users can choose for their chats to be ‘secret’ which means they will be end-to-end encrypted, meaning that only the sender and receiver can read the message – but you must opt in to have the additional level of privacy. But group chats, one of the app’s most popular features, cannot be end-to-end encrypted. 

How Does Telegram Deal With Controversial Content? 

One of the biggest issues with Telegram is the content shared in the app and the company’s “hands-off” approach to moderation. Telegram’s a truly unique combination of messaging and social media plus its publicly relaxed content moderation strategy means it attracts a certain style of the user who may have been outed from more mainstream online platforms. 

A quick Google will produce multiple examples of how Telegram has been widely used by fringe political groups. Security experts have acknowledged that Telegram is in fact ‘the app of choice’ for terrorist organizations. Neo-nazi groups have reportedly used Telegram as a recruiting platform and the far-right QAnon has reportedly set up a home on Telegram after messaging app Parler was suspended earlier this year. 

Now, of course, this sounds completely horrid and makes Telegram seem very unattractive. But I can assure you that my Telegram user experience has been quite bland. I have been using the app on and off for several months now and I’ve never been exposed to political or fringe content but I also haven’t gone looking for it. For me, it has been yet another way of connecting with people in my life with a couple of great stickers to assist! 

Should My Kids Use It? 

In my opinion, Telegram is an app best suited for a robust adult mind. According to the terms and conditions, Telegram users need to be 16+ to join up however as worldly parents, we all know those age restrictions are not a deterrent for many young people! 

While my experience has been no different from using other messaging apps like WhatsApp, I believe Telegram is not an appropriate app for an under 18 as there are too many risks:  

• Pornographic and violent sexual content is available on Telegram if you chose to seek it out 
• The ‘find people nearby’ feature allows users to be targeted with inappropriate material if settings haven’t been adjusted 
• The ‘group nearby’ feature allows users to view groups without joining. There is a risk these groups may contain violent or harmful material. 
• The lack of content moderation means users could be exposed to fringe political material which may be traumatic and hard to process. 

Now, of course, it is possible to adjust settings to minimize the risks when using the app. If location services are turned off and profiles are not marked visible, then finding ‘random’ groups and people via location will not be an option. And if the default privacy settings are adjusted so that your child can only be contacted by ‘my contacts’ as opposed to ‘everybody’ then this will minimize the risk of receiving communication from people they don’t know. 

So, if you or your kids are looking for a top-notch end-to-end encrypted messaging app then there are definitely better options around, such as Signal. And let’s not forget about WhatsApp which offers end-to-end encrypted messaging on everything sent in the app. Yes, your information will be shared with Facebook but only if you are messaging a business on the app, according to the company. Messages and calls between parties are still protected by end-to-end encryption. So many choices, so many messages to send! 

Happy messaging!
