South Korea has extradited a 29-year-old Lithuanian hacker accused of stealing $1.8 million in cryptocurrency using malware. The extradition follows a five-year investigation by the National Office of Investigation. The hacker allegedly used KMSAuto, a fake Windows activation tool, to transfer funds into his wallets, affecting 3,100 wallets after being downloaded over 2 million times. Authorities from South Korea and Lithuania collaborated to track the stolen cryptocurrency, leading to a raid on the suspect's home in December 2024, where 22 devices were seized. Over 840 transactions were blocked during the investigation. This case underscores the urgent need for enhanced cryptocurrency regulations to prevent similar cybercrimes.
