On February 21, the cryptocurrency exchange Bybit suffered a loss of $1.46 billion due to a breach of its cold Ethereum wallet. The attack was orchestrated by the hacker group Lazarus Group, which employs cross-chain bridges and coin mixing services for laundering funds. The hackers primarily utilized THORChain to exchange Ethereum for Bitcoin.<\/p>\n
Together with the team at Mixer.Money<\/a>, we examine how this incident might affect the reputation of Bitcoin mixers and what steps can be taken to minimize the risk of potential blockages.<\/p>\n The use of cross-chain bridges and Bitcoin mixers is not inherently criminal. However, like any financial tools, these services can attract criminals, especially when they need to launder large sums, as evidenced by the record volume of THORChain swaps last week.<\/p>\n \n\u201cThis means that exchanges will scrutinize and block CoinJoin transactions or those associated with non-KYC<\/span> services more rigorously. As a result, ordinary users who employ cross-chain solutions, as well as centralized and decentralized mixers for anonymizing their transfers, may be affected,\u201d comment Mixer.Money.<\/em><\/cite><\/p><\/blockquote>\n They note that increased scrutiny should not overshadow the primary goal of mixing \u2014 protecting user privacy.\u00a0\u00a0<\/p>\n In practice, hackers will continue to use any available tools for laundering, and there is little that can be done about it. Their main objective is to quickly blend stolen assets with those of regular users to complicate tracking and recovery.<\/p>\n To mitigate the risk of blockages, the Mixer.Money team advises against using CoinJoin \u2014 a Bitcoin transaction anonymization algorithm that mixes bitcoins from multiple users, then divides them into equal parts and sends them to recipients.<\/p>\n Service representatives acknowledge that exchanges might automatically block accounts receiving funds processed through CoinJoin.<\/p>\n \n\u201cNow is not the best time to experiment with CoinJoin. Exchanges are trying to identify and freeze large amounts of stolen funds, so using such services will attract attention and arouse suspicion. Subsequently, you will have to explain why you conducted such transactions,\u201d warn experts.<\/em><\/cite><\/p><\/blockquote>\n To ensure anonymity on the blockchain and avoid blockages, they recommend using services capable of concealing the passage of coins through transaction anonymization solutions.<\/p>\nCrime and Privacy<\/h2>\n
