The US Justice Department has taken action against an alleged ransomware operator, seizing over $2.8 million in cryptocurrency along with cash and other assets as part of a criminal case. The agency unsealed six warrants authorizing the seizure of funds held by Ianis Aleksandrovich Antropenko, alongside $70,000 in cash and a luxury vehicle. Antropenko faces charges related to computer fraud and abuse, and conspiracy to commit money laundering. “As alleged in the unsealed warrants, the cryptocurrency and other assets are proceeds of (or were involved in laundering the proceeds of) ransomware activity,” the Justice Department notice reads. The agency highlights Antropenko’s use of crypto mixing services like ChipMixer, which was shut down by a coordinated international operation in 2023. Antropenko also allegedly laundered cryptocurrency through exchanges and cash deposits into structured accounts.
