1. Drift $285M Exploit = Multisig Social Engineering is the New Attack Vector
Drift protocol lost $285M when attackers socially engineered multisig signers — vault drained in 12 minutes. 20+ Solana protocols affected, Circle froze USDC bridge but $270M already transferred. Root cause: human element in multisig, not smart contract code. Due diligence must now include: How is multisig signer identity verified? What social engineering training exists? This attack bypassed all technical security measures by targeting humans.
