BonkDAO, a decentralized autonomous organization on the Solana blockchain, has been hacked, resulting in the loss of approximately $20 million in BONK tokens. The breach occurred through a malicious governance proposal that successfully drained the DAO's treasury. The attack highlights vulnerabilities in decentralized governance mechanisms, where proposals can be manipulated to execute unauthorized transactions. BonkDAO is currently investigating the incident and working on measures to prevent future breaches.
