Adding to the existing roadblocks of the decentralized crypto mixer Tornado Cash, an attacker managed to gain full control of the governance through a malicious proposal.\u00a0<\/p>\n

On May 20 at 3:25 ET, an attacker successfully granted 1.2 million votes to a malicious proposal. Given that the proposal received more than 700,000 legitimate votes, the attacker gained total control over Tornado Cash governance.<\/p>\n

<\/p>\n

As explained by @samczsun:<\/p>\n

\n

\u201cOnce the proposal was passed by voters, the attacker simply used the emergencyStop function to update the proposal logic to grant themselves the fake votes.\u201d<\/p>\n<\/blockquote>\n

<\/p>\n

As shown above, they also attempted deploying a contract that could potentially revert the changes while still suggesting the community to withdraw their funds. Cointelegraph also came across a distress call from one of Tornado Cash\u2019s community developer who confirmed the above developments, stating:<\/p>\n

\u201cThere was an attack on the protocol this morning that you already know about. All day, another community developer and I thought about what to do, but the situation is close to hopeless – currently the attacker controls Governance.\u201d<\/p><\/blockquote>\n

A former Tornado Cash developer is reportedly working on building a new crypto mixing service from scratch, which addresses the \u201ccritical flaw\u201d existing in Tornado Cash.<\/p>\n
