The hacking incident at Indian cryptocurrency trading platform WazirX has once again drawn market attention. According to data from tracking platform MistTrack, hackers have transferred 1600 Ethereum (ETH) to the well-known decentralized mixing service, Tornado Cash. This operation means that hackers are attempting to obscure the origin and path of their illicit gains through mixing methods, further complicating the investigation. It is estimated that the value of this transaction exceeds $3.85 million, highlighting the severity of the event. Both WazirX and relevant law enforcement agencies have launched investigations aimed at protecting user assets and holding the hackers accountable. For the cryptocurrency industry, this incident serves as a reminder to all market participants of the importance of security measures, while also raising higher requirements for the compliance and security of decentralized mixing services.
