According to CertiK monitoring, the attacker of Cashio App, which had been idle for 101 days, transferred 100 ETH to Tornado Cash.
Currently, there are still 6316 ETH (about 10.9 million) in the EOA account address 0xfe4. The funds come from the vulnerability attack in March 2022 that caused a loss of about 52 million US dollars, which was caused by the unlimited coin minting vulnerability.
