In its largest transaction, the HECO Chain exploiter sent 11,300 ETH worth roughly $39.5 million in one transfer.
A crypto wallet address linked to the HECO Chain exploiter transferred and anonymized nearly 40,392 Ether (ETH) on the crypto-mixing protocol Tornado Cash in eight days.
According to crypto investigator PeckShield, the HECO Chain exploiter made 19 outbound transfers to Tornado Cash addresses in an attempt to make approximately $145.7 million worth of stolen Ether nearly impossible to trace.
The majority of the funds were sent to a single Tornado Cash address, while one transaction of 0.2 ETH worth $699 was sent separately to a different address in Tornado Cash.
