An attacker who sparked community-wide panic by hijacking the Tornado Cash governance is now proposing to undo their hack — and while not everyone feels the hacker can be trusted, they apparently have little choice in the matter.
On May 21, the passage of a malicious proposal allowed the attacker to gain complete control over Tornado Cash’s governance. With total control over the governance of the decentralized crypto mixer, the attacker was in a position to inflict massive losses, considering they could withdraw all of the locked votes, drain all of the tokens in the governance contract and brick the router.
