A malicious signature in the context of digital assets refers to a cryptographic signature generated by an unauthorized or compromised private key, or one that authorizes an unintended, harmful action. This signature is typically used to approve a fraudulent transaction, such as transferring funds from a user’s wallet without their consent. It often results from phishing attacks, malware, or vulnerabilities in smart contracts. Such signatures enable the theft or misuse of digital assets.
