Mixing protocols have become standard for black industry, this laundering speed is even faster than DeFi mining.

According to on-chain analyst Specter’s monitoring, the Step Finance attacker is actively routing the previously stolen funds to Ethereum via cross-chain bridges and depositing them into the mixing protocol Tornado Cash. The attacker first transferred $5.8 million in assets across chains and received 3,874 ETH; then transferred another $21.4 million, receiving 12,124 ETH. Currently, the attacker has cumulatively deposited $10.8 million into Tornado Cash, and the remaining $16 million in stolen funds are still being laundered. In addition, within the past five hours, including the case mentioned above, two attackers have collectively transferred more than 21.0 million US dollars to Tornado Cash.
