A significant phishing attack resulted in the loss of $50 million USDT from a major whale or institution on December 21. The victim has offered a $1 million reward for the return of the funds, but the attacker has not responded. The stolen USDT was reportedly converted into Ethereum and laundered through Tornado Cash, a privacy-focused protocol. This incident underscores the persistent security challenges within the cryptocurrency sector, highlighting the vulnerabilities that even large entities face. The use of Tornado Cash for laundering stolen funds continues to pose a significant obstacle for tracking and recovering assets in the crypto ecosystem.
