Drift Protocol experienced a security breach where a malicious actor gained unauthorized access to administrative powers via a "durable nonce" attack on the Solana network. The incident affected a multisig controlling $500 million in depositor funds, which reportedly lacked a timelock mechanism and required only 2 out of 5 signatures. The sentiment is highly critical, labeling the protocol's security measures as woefully inadequate following the rapid takeover of its Security Council.
