A hacker responsible for the Bitrue exchange breach in April of last year, which resulted in the theft of approximately $23.5 million in cryptocurrency, has transferred 1050 ETH to Tornado Cash. This move, reported by PeckShield, strongly suggests an attempt to launder the stolen funds and obscure their origin. Tornado Cash is a decentralized, non-custodial privacy solution built on Ethereum. It enables users to deposit ETH and withdraw it to a different address, breaking the on-chain link between the source and destination. While legitimate uses exist, it is often used for illicit activities. The hacker's current holdings include a substantial 5,111 ETH and 16 million DAI, totaling around $25.5 million. The transfer to Tornado Cash highlights the ongoing challenge of recovering stolen cryptocurrency and the increasing sophistication of cybercriminals in evading detection. The incident serves as a stark reminder of the vulnerabilities present within cryptocurrency exchanges and the importance of robust security measures. ```
