Drift Protocol Incident: Multisig Governance Compromise via Durable Nonce Exploitation
On April 1, 2026 (UTC), Drift Protocol on Solana suffered a $285.3M loss after an attacker exploited Solana's durable nonce mechanism to delay the execution of phished multisig approvals, ultimately transferring administrative control of the protocol's 2-of-5 Squads governance with zero timelock. With full admin privileges, the attacker created a malicious collateral market (CVT), inflated its oracle price, relaxed withdrawal protections, and drained USDC, JLP, SOL, cbBTC, and other assets through 31 rapid withdrawals in approximately 12 minutes. This incident highlights how durable nonce-based delayed execution can decouple signer intent from on-chain execution, bypassing the temporal assumptions that multisig security implicitly relies on.
