Including to the prevailing roadblocks of the decentralized crypto mixer Twister Money, an attacker managed to achieve full management of the governance via a malicious proposal.
On Might 20 at 3:25 ET, an attacker efficiently granted 1.2 million votes to a malicious proposal. Provided that the proposal obtained greater than 700,000 authentic votes, the attacker gained complete management over Twister Money governance.
On 2023/05/20 at 07:25:11 UTC, Twister Money governance successfully ceased to exist. By means of a malicious proposal, an attacker granted themselves 1,200,000 votes. As that is greater than the ~700,000 authentic votes, they now have full management.https://t.co/nY87XmrYgT pic.twitter.com/h9qjc3xRqz

The data was shared by @samczsun of research-driven know-how funding agency Paradigm, who revealed that, when sharing the malicious proposal, the attacker claimed that it used a logic just like a proposal that had beforehand handed by the group. Nevertheless, this time, the proposal had an extra perform.
As defined by @samczsun:

On the time of writing, the attacker “merely withdrew 10,000 votes as TORN and bought all of it,” mentioned @samczsun.
The assault comes as a reminder to crypto traders to vet proposal descriptions and logic. An lively group of Twister Money, who goes by the identify Tornadosaurus-Hex or Mr. Tornadosaurus Hex, confirmed that every one funds in Governance are probably compromised and requested all members to withdraw all funds locked in governance.
As proven above, in addition they tried deploying a contract that would probably revert the modifications whereas nonetheless suggesting the group to withdraw their funds.

“There was an assault on the protocol this morning that you simply already learn about. All day, one other group developer and I thought of what to do, however the scenario is near hopeless – at the moment the attacker controls Governance.”
The group is at the moment searching for Solidity builders that may assist save the protocol from extinction. They moreover acknowledged that “we want contact with Binance – this trade has extra tokens than the attacker.”
