A cunning hacker, who made off with a whopping $25 million in cryptocurrency from Kronos research firm earlier this year, has been secretly laundering the stolen funds through an anonymity service. The cybercriminal's clever tactics have been uncovered, revealing a trail of transactions that led to the notorious Tornado Cash mixer.

The hacker's modus operandi involved transferring millions of dollars' worth of Ethereum coins through a series of complex transactions, ultimately ending up at Tornado Cash. This cryptocurrency mixer, designed to conceal the sender's identity, has been exploited by hackers to launder stolen funds and capitalize on them through decentralized exchange platforms.

The use of such privacy-enhancing tools has sparked debate within the cryptocommunity, with some members supporting the right to privacy and others condemning the misuse of these tools for illicit activities. The US government has taken a firm stance, imposing sanctions on Tornado Cash and convicting its founders of money laundering and sanctions violations.

Crypto-analyzing firm PeckShield has issued a warning about the suspicious transactions, alerting users to the hacker's attempts to conceal the stolen funds. The exploitation of Kronos Capital's API keys in November 2023 allowed hackers to access and steal millions of dollars' worth of cryptocurrency, prompting the company to shut down its trading services for a thorough investigation.
