A threat actor infected their own computer with an information stealer, which has allowed Israeli threat intelligence company Hudson Rock to uncover their real identity.
Using the online moniker ‘La_Citrix’, the threat actor has been active on Russian speaking cybercrime forums since 2020, offering access to hacked companies and info-stealer logs from active infections.
La_Citrix, Hudson Rock says, has been observed hacking into organizations and compromising Citrix, VPN, and RDP servers to sell illicit access to them.
The hacker, the cybersecurity firm says, was careless enough to infect their own computer with an information stealer and to sell access to the machine without noticing.
This allowed Hudson Rock to explore the cybercriminal’s computer, which had been used to perpetrate intrusions at hundreds of companies. The computer contained employee credentials at almost 300 organizations, and the browser stored corporate credentials used to perform hacks.
According to Hudson Rock, La_Citrix was employing information stealers to exfiltrate corporate credentials that were then used to access organizations’ networks without authorization.
Further analysis of the threat actor’s computer also helped the cybersecurity firm discover their real identity and their location.
“Data from La_Citrix’s computer such as ‘Installed Software’ reveals the real identity of the hacker, his address, phone, and other incriminating evidence such as ‘qTox’, prominent messenger used by ransomware groups, being installed on the computer,” Hudson Rock notes.
The threat intelligence company, which notes that it has knowledge of thousands of hackers who accidentally infected their own computers with malware, says it will forward the uncovered evidence to the relevant law enforcement authorities.
“This is not the first time we’ve identified hackers who accidentally got compromised by info-stealers, and we expect to see more as info-stealer infections grow exponentially,” the company notes.
