Definition ∞ Malicious Transaction Signing occurs when a user unwittingly authorizes a blockchain transaction that has been subtly altered by an attacker to transfer assets to an unauthorized address. This typically happens through deceptive interfaces or malware that modifies the transaction details before the user approves it. It represents a direct compromise of a user’s control over their digital assets.
Context ∞ Incidents of malicious transaction signing are a recurring concern in cryptocurrency security news, often resulting from phishing campaigns or wallet drainer malware. The challenge lies in users accurately verifying complex transaction details before approval. Future solutions aim for clearer transaction previews, hardware wallet improvements, and enhanced client-side security tools to prevent such deceptive authorizations.
