Fake token exploit crashes CETUS 40%, BULLA and MOJO drop 90%

Cetus Protocol, the largest liquidity provider and decentralized exchange in the Sui ecosystem, has suspended trading following an exploit that led to a $260 million liquidity loss.
Preliminary reports indicate that the attacker used fake tokens like BULLA to manipulate price curves and reserve calculations, allowing them to extract real assets.
By providing liquidity with near-zero value, the hacker repeatedly withdrew actual assets such as SUI and USDC without making significant deposits.
