In recent developments, it has been reported by Lookonchain that three prominent hackers have collectively laundered 17,800 Ether (approx. $42.7 million) through Tornado Cash in just the past three days. Tornado Cash is a cryptocurrency mixing service designed to obscure the origin and destination of transactions, making it a preferred tool for cybercriminals looking to conceal their ill-gotten gains.
Breakdown of the Deposits
1. Penpie Xyz Exploiter (9,600 ETH – $23M)
The largest amount laundered in this timeframe came from the Penpiexyz exploiter, who funneled 9,600 ETH, equivalent to $23 million, through Tornado Cash. This was a result of a major attack on Penpiexyz, a decentralized finance (DeFi) platform, where the perpetrator exploited a flaw in the smart contracts. This incident not only impacted the platform but also ignited discussions about the vulnerabilities within DeFi systems. The laundered assets are now challenging to trace due to their movement through Tornado Cash.
2. WazirX Exploiter (7,200 ETH – $17.3M)
Another significant user of Tornado Cash is the hacker involved in the WazirX exchange theft. Within a week, the attacker transferred 7,200 ETH, valued at approximately $17.3 million, through the service. This hack exposed critical vulnerabilities within WazirX, one of India’s largest crypto exchanges, and has made the recovery of stolen funds particularly challenging due to their laundering through Tornado Cash.
3. Fenbushi Capital Exploiter (1,000 ETH – $2.4M)
The third notable deposit was made by the hacker who targeted Bo Shen, the owner of Fenbushi Capital. The thief managed to transfer 1,000 ETH, valued at $2.4 million at the time, through Tornado Cash. This attack was directed at Shen’s personal wallet and stands out as one of the largest individual hacks on crypto-related platforms. Shen’s ongoing efforts to trace the stolen funds have been hampered by the hacker’s use of Tornado Cash.
Tornado Cash’s Role
Despite numerous sanctions and bans on its usage, Tornado Cash remains a preferred platform for cybercriminals. The service’s ability to obscure the origins and destinations of funds makes it nearly impossible to trace stolen assets. Given the increasing frequency of crypto crimes, regulators face significant challenges in curbing the use of Tornado Cash and similar DeFi applications involved in unlawful activities.
The surge in stolen funds being funneled through Tornado Cash underscores the urgent need for enhanced security measures within the blockchain space. Strengthening these measures is crucial to prevent large-scale thefts and facilitate the tracing of stolen assets, ultimately safeguarding the integrity of the cryptocurrency ecosystem.
