Sui Network Freezes $160M Hacker Assets: Critical Response

The Sui Foundation, alongside its validators, successfully froze $160 million in stolen assets following a significant exploit on Cetus, a leading decentralized exchange on the Sui network.

orchestrated a response freezing $160 million in assets after a major hack on Cetus. The vulnerability was identified as a flaw in Cetus’ smart contract logic. Adeniyi Abiodun of Mysten Labs noted it wasn’t due to Sui’s protocol:

“It’s not a bug in Sui consensus, it’s not a bug in Move,” describing the exploit as a failure in Cetus’ application logic rather than Sui’s protocol itself.

Following the hack, the attacker managed to remove $223 million to $260 million from liquidity pools, severely affecting the ecosystem. With the community’s help, $160 million in stolen funds were frozen, while $60 million was laundered through Ethereum.

The exploit’s impact extended beyond financial losses, striking a blow to Sui’s DeFi ecosystem and causing liquidity issues. Trading on Cetus was temporarily halted but has resumed after swift patch implementation.
Cetus Protocol Update

The incident raised questions about validator power within decentralized systems, with validators updating configurations to block specific transactions. This event further catalyzed debates over network governance and decentralization principles across the ecosystem.

Cetus team has committed to full recovery of affected users’ funds, exploring strategies like legal action or whitehat hacker negotiations. Community on-chain votes will potentially guide the recovery strategy for maximum fund restitution.
