Ukrainian hacker gets four years in US prison over Conti ransomware attacks

A Ukrainian national, Oleksii Lytvynenko, was sentenced to four years in a U.S. prison after pleading guilty to participating as a hacker and developer in the Conti ransomware operation that targeted more than 1,000 victims across dozens of countries and reportedly collected over $150 million in ransoms; investigators found stolen victim data in his accounts and evidence he continued ransomware-related activity after Conti’s shutdown, and the report notes related arrests and a leak of Conti’s internal chats.
