Decentralized privacy protocol Hinkal has experienced a significant security breach, resulting in the theft of approximately 800,000 USDC. According to CertiK Alert monitoring, the suspicious activity involved an EOA address, 0xbB3f01a1b1C68F3DEB36C55342b5F5706c32fc20, which executed a "Proofless Deposit" operation followed by multiple "Transact" transactions to siphon funds from the Hinkal contract. The incident raises concerns about the security measures in place for decentralized protocols.
