Blockchain News tracked down a recent case of cryptocurrency cleansing. It was reported that an attacker labeled as Penpiexyz_io used the TornadoCash cryptographic mixing service to cleanse the 1660 Ethereum (ETH) they had previously stolen. This is not the first instance; the attacker has already laundered a total of 11,160 ETH (approximately $27 million) through similar methods over time. As an advanced privacy technology, TornadoCash makes tracing fund flows extremely challenging by obscuring transaction paths and amounts. This incident underscores the intricacy and challenges posed by money laundering activities within the cryptocurrency sector.
