Financial Loss $3.9M (3,900,000 USD)

Incident Details

Unleash Protocol, a project promising to allow creators to register their intellectual property on the blockchain, has been exploited for around $3.9 million. An attacker was able to gain administrative access, despite the project’s governance system ostensibly being protected by a multisignature wallet. They then deployed a new smart contract, which allowed them to siphon assets from the project. The attacker then bridged the funds to ETH and laundered them via the Tornado Cash cryptocurrency mixer.

Total loss estimated at $3,900,000.
