ACryptoS Reports $665,000 Attack Loss Across 77 Vaults on Five Chains

ACryptoS said an attack caused about $665,000 in losses across 77 vaults on five blockchains, prompting the DeFi yield protocol to close deposits and urge users to withdraw their funds. An analysis released after the incident by ACryptoS found that a missing input check let the attacker make a very small deposit in one asset and receive most of the shares in affected vaults. The team has installed an emergency fix, but new deposits remain disabled while withdrawals are still available. ACryptoS said it is tracking the stolen funds after they moved through multiple cross-chain protocols. The project offered the attacker a 10% bounty for returning the funds. The team said it no longer has enough resources to maintain the protocol and has stopped maintenance.
