He faces charges including wire fraud and aggravated identity theft, with a maximum 20-year prison sentence for his most serious charge. Separately, Sergei Filimonov was extradited from Georgia and appeared in an Atlanta federal court on Sept. 4. He is accused of maintaining technical infrastructure for a scheme that used fake bank websites and sponsored Google links to steal credentials. The Justice Department stated the operation resulted in $28 million in unauthorized transfers.
Hacking and State-Linked Allegations
In June, Thailand extradited 36-year-old Denis Obrezko to Boston. Authorities accuse Obrezko of supporting Void Blizzard, a hacking group linked to Russian interests by Microsoft. The group has targeted government agencies, defense firms, and media outlets in NATO countries and Ukraine since at least April 2024. Investigators reportedly found summaries of over 13,000 stolen emails belonging to lawmakers on Obrezko's phone. He faces up to 10 years in prison if convicted of conspiracy to commit computer fraud and unauthorized access.
