Recently, wallets linked to the CoinStats exploiter made a significant move by transferring almost $1 million in Ether to the controversial crypto mixing protocol Tornado Cash. This action comes shortly after CertiK, a blockchain security firm, identified two wallets connected to the CoinStats exploit in June moving a total of 311 ETH to Tornado Cash. One wallet transferred 211 ETH, while the other moved 100 ETH, raising concerns about money laundering activities.
CoinStats disclosed a security breach on June 22nd that impacted iOS users who received fraudulent notifications promising rewards. As a result, the company promptly halted its application to address the breach and confirmed that only 1.3% of total wallets, amounting to 1,590 in total, were affected. Despite this incident, CoinStats assured its users that connected wallets and centralized exchanges remained secure. Subsequent updates on July 5th revealed that investigations into the security breach were ongoing, with no mention of involving law enforcement authorities.
Despite experiencing legal challenges and crackdowns, Tornado Cash remains a popular choice for money laundering stolen funds. In August 2022, the US Department of the Treasury blacklisted the service, prohibiting its use by US citizens, residents, and companies. Following this action, the project’s web domain and GitHub accounts were shut down. Further complications arose when developer Alexey Pertsev was arrested in Amsterdam on suspicion of aiding criminal financial activities through the Ethereum mixing service, resulting in a 5-year and 4-month prison sentence. Additionally, two more developers, Roman Storm and Roman Semenov, faced charges related to assisting $1 billion in money laundering, with Storm’s arrest occurring in Washington State.
The movement of funds from the CoinStats exploit to Tornado Cash highlights the ongoing challenges faced by the cryptocurrency community in combating illicit activities. The use of crypto mixing protocols like Tornado Cash for money laundering continues to pose a significant threat, necessitating increased vigilance and regulatory oversight to protect users and maintain the integrity of the digital asset ecosystem.
