Russian national extradited to US for alleged involvement in bank-account takeover scheme
Authorities extradited a 36-year-old Russian national from the Republic of Georgia under accusations of widespread bank-account takeover attacks, including a scheme to defraud two banks of more than $6.3 million, the Justice Department said Tuesday.
Sergei Anatolyevich Filimonov and unnamed co-conspirators ran an extensive operation starting in November 2023 to spoof domains of banks, obtain credentials of legitimate customers and use those details to steal money from accounts with large balances, according to court records.
Filimonov and his co-conspirators allegedly collected more than 5,000 victim login credentials to various banks, including those assigned to employees with access to a company headquartered in Atlanta and another business with offices in Cumming, Ga.
Authorities said Filimonov and his co-conspirators registered and maintained spoofed domains of banks, purchased sponsored links to direct unsuspecting victims to those domains, and stole credentials from those banks’ customers when they attempted to log into the fraudulent sites.
The alleged bank-account takeover crew also created infrastructure to store victim login credentials and tricked victims into providing additional details to bypass security controls.
Prosecutors said Filimonov and his co-conspirators caused and attempted to cause the unauthorized transfer of nearly $5.58 million from one unnamed bank in June 2024 and $735,000 from another bank in November 2024. Both banks have local branches in the Northern District of Georgia and maintain headquarters in North Carolina, according to the indictment.
Officials previously seized the domain, which the co-conspirators allegedly used to store credentials harvested from the spoofed banking sites in December 2025. The FBI at the time said it identified at least 19 victims in the U.S. linked to the domain and put total attempted losses at about $28 million, including confirmed losses of about $14.6 million.
Filimonov is charged with conspiracy to commit bank and wire fraud, access device fraud conspiracy, multiple counts of bank and wire fraud, possession of unauthorized access devices and aggravated identity theft. He faces up to 175 years in prison.
He pleaded not guilty Sept. 4 and remains detained in the Northern District of Georgia.
