After the Penpie project called out to the hacker and requested communication, the hacker was still transferring ETH through Tornado.
The hacker has transferred 2,900 ETH ($6.89M) through Tornado through the 0xD44...cC3 address.
It seems that he does not intend to return the stolen assets and become a white hat hacker to get a bounty.
