Ukraine Arrests Key Cybercriminals Behind Notorious Ransomware Families

Ukrainian law enforcement, in collaboration with international authorities, has arrested key individuals involved in multiple ransomware schemes, including the LockerGoga, MegaCortex, and Dharma families. The suspects are accused of targeting over 1,800 victims across 71 countries since 2019, using tactics such as brute-force attacks, SQL injections, and phishing emails. The cybercriminals encrypted over 250 servers belonging to large corporations, resulting in losses exceeding several hundreds of millions of euros. The investigation also revealed their involvement in deploying the now-defunct Hive ransomware. The arrests are part of a broader effort to combat cybercrime, following recent takedowns of other ransomware operations.
