After months of dormancy, attackers from the Step Finance and UXLINK hacks moved approximately $38 million in stolen crypto through Tornado Cash in a single afternoon, laundering the funds to obscure their trail.
The Step Finance attacker sold 261,933 SOL ($21.4M) after 5 months, bridged to Ethereum, bought 12,128 ETH, and deposited into Tornado Cash. The UXLINK attacker also deposited 6,038 ETH into Tornado Cash, with total deposits exceeding $21M from two separate incidents.
Funds have been laundered through Tornado Cash; further monitoring ongoing.
The UXLINK exploiter swapped ~10.54M DAI for 6,000.8 ETH and deposited 6,038 ETH into Tornado Cash, totaling 14,336.6 ETH deposited over two weeks.
