A multi-sig compromise signifies a security breach where a multi-signature (multi-sig) wallet’s required number of private key approvals is subverted. Multi-sig wallets typically require a predefined number of signatures from distinct key holders to authorize a transaction, thereby enhancing security. A compromise implies that an unauthorized party has gained control over sufficient keys or has exploited a vulnerability to bypass the security threshold, potentially leading to the illicit transfer of funds. This represents a critical failure in the intended security architecture.
