South Korea’s largest crypto exchange, Upbit, suffered a significant loss of $30 million after a security flaw exposed user funds. Investigations are underway, focusing on the Lazarus Group, a suspected North Korean hacking syndicate known for past attacks. Experts suspect a weakness in Upbit’s software allowed malicious actors to steal funds. The incident highlights vulnerabilities within digital asset exchanges and has sparked scrutiny around blockchain security protocols. Upbit confirmed the loss and initiated emergency measures, suspending deposits and withdrawals while patches were implemented. Authorities are analyzing suspicious cross-chain transactions and tracking potential money laundering techniques used by the hackers.
