Definition ∞ A multisig exploit refers to a security breach targeting a multi-signature wallet or smart contract. Multi-signature schemes require multiple private keys to authorize a transaction, offering enhanced security over single-signature systems. An exploit typically bypasses these protective measures, often through vulnerabilities in the contract code, compromised key management, or social engineering attacks. This can result in unauthorized fund transfers.
Context ∞ News reports on multisig exploits frequently detail significant losses of digital assets from decentralized finance (DeFi) protocols, exchanges, or institutional holdings. These incidents highlight the ongoing need for rigorous smart contract auditing and robust operational security practices for managing private keys. Such exploits underscore the persistent security risks associated with complex cryptographic systems.
