A Russian national accused of running a scheme that stole thousands of American bank account credentials appeared in federal court in Atlanta last week after being extradited from the Republic of Georgia.
Sergei Anatolyevich Filimonov, 36, a web developer, was arraigned Friday in the Northern District of Georgia on fraud and aggravated identity theft charges. A federal grand jury indicted him on Nov. 4, 2025, in connection with what prosecutors describe as a transnational credential-harvesting and bank-fraud conspiracy.
According to court documents, Filimonov and his co-conspirators built spoofed websites designed to look like the real login pages of federally insured banks. They allegedly bought sponsored search-engine links to funnel unwitting bank customers to these fake pages, where victims typed in their usernames and passwords without knowing they’d been redirected.
Once the credentials were captured, prosecutors say, the conspirators used them to log into victims’ real accounts, check balances, and move money out through unauthorized wire transfers.
The indictment alleges Filimonov personally developed much of the technical infrastructure behind the operation, including software built to capture and transmit stolen login data and databases that held more than 5,000 compromised sets of credentials.
Prosecutors say the group attempted to siphon millions of dollars from victim accounts, including accounts belonging to companies located within the Northern District of Georgia.
As part of the investigation, the Department of Justice previously seized a domain, web3adspanels.org, which had served as a backend server storing credentials harvested through the fraudulent bank sites. That seized database reportedly contained thousands of stolen logins, including some belonging to victims in the Northern District of Georgia.
The FBI’s Atlanta field office is continuing to investigate the case, according to the Justice Department.
Filimonov faces multiple federal charges. If convicted, he faces a minimum of two years in prison and a maximum sentence of up to 175 years.
