The address used by the hacker to send the funds to Tornado Cash had been dormant since November, with the last transaction occurring 166 days ago.
A hacker involved in the $4.67 million exploit of the decentralized finance lending protocol Voltage Finance in 2022 has moved some of the stolen Ether to Tornado Cash after a short hibernation.
Blockchain security firm CertiK said in a May 6 post to X that the 100 Ether (ETH), worth $182,783 at current prices, was moved from a different address initially used in the exploit but can be traced back to the hacker.
In March 2022, the exploiter took advantage of a “built-in callback function” in the ERC677 token standard and allowed them to drain the platform’s lending pool through a reentrancy attack, according to CertiK.
