[ACryptoS: Vault Attack Causes $665,000 Loss, Project Announces Shutdown] DeFi yield aggregation protocol ACryptoS announced that due to a vault attack, deposit functionality has been disabled, while withdrawal functionality remains open. ACryptoS analysis suggests that due to a lack of input validation, attackers only needed to deposit a very small amount of tokens to mint the vast majority of the vault's contents. The attack affected 77 vaults across 5 chains, resulting in a total loss of approximately $665,000. The stolen funds have been transferred through multiple cross-chain protocols, and the attackers have been offered a 10% bounty for the funds. Furthermore, ACryptoS stated that due to its inability to continue maintenance, the project has ceased operations and urged users to withdraw their assets as soon as possible.
