ChainCatcher reports that the decentralized anonymous lottery protocol Foom Cash lost approximately $2.26 million in a security breach, but white-hat hackers intervened in time to recover $1.84 million (about 81% of the stolen funds).
The security incident was caused by a critical error during Foom Cash’s deployment, specifically related to a Groth16 verifier configuration issue, which allowed attackers to submit forged proofs to the protocol. A white-hat hacker named Duha identified the vulnerability and quickly protected the funds on the Base chain, while security firm Decurity handled the rescue of funds on Ethereum. In return, Foom Cash paid the white-hat hacker a bounty of $320,000 and paid Decurity $100,000 in security fees.
