An alleged member of the FIN7 hacking group is set to plead guilty, admitting to a role in a criminal organization that used front companies and array of fraud techniques to steal more than $1 billion from victims worldwide, CyberScoop has learned.
Attorneys for Denys Iarmak, a Ukrainian national, have notified a federal court in Washington state that Iarmak intends to change his plea after he declared himself not guilty at a May 2020 arraignment hearing. While one defense counselor said Iarmak could change his mind before his next hearing, scheduled for Nov. 22, attorneys have agreed in principle to a plea deal with the U.S. Department of Justice.
“That’s what’s most likely,” said defense attorney Michael Craig Nance, who is representing Iarmak in the Western District of Washington. “It’s not final until a person stands in court and says they’re guilty.”
Iarmk was initially charged with a range of criminal counts, including intentional damage to a protected computer, aggravated identity theft and wire fraud. To which charges he intends to plead guilty remains unclear.
FIN7 is a notorious hacking group best known for masquerading as a technology company in order to recruit talent and cloak its malicious activity. U.S. prosecutors have alleged that by fabricating a firm called Combi Security, FIN7 targeted restaurant chains including Chipotle, Red Robin, Taco John and the department store Saks Fifth Avenue, among others. In some cases, attackers posed as U.S. Securities and Exchange Commission officials and angry restaurant customers to dupe victims into opening email messages, infecting their computers with malicious software.
Iarmak, who went by the online alias GakTus, appeared to work as a penetration tester, in which he was tasked with probing victims’ digital defenses and infiltrating their systems. Upon finding vulnerabilities, Iarmak would provide that information to a FIN7 administrator, who instructed other members of the hacking group on how to exploit the weakness, according to a 2019 indictment.
The group would then gather usernames, passwords and payment card information to sell on illicit forums, such as the Joker’s Stash, the charges allege.
Two of Iarmak’s alleged associates, Andrii Kolpakov and Fedir Hladyr, were sentenced this year to seven and 10 years in prison, respectively. Kolpakov was convicted of supervising a small team of hackers who were responsible for monetizing illicit access, while Hladyr functioned as a kind of technical guru, controlling an instant messaging service that members used to communicate in real time.
The FIN7 group has reportedly remained active in the months since, using the name Bastion Secure to hire technical specialists who carried out attacks on the group‘s behalf, The Wall Street Journal reported.
