Definition ∞ Wallet address replacement refers to a deceptive practice where malicious software or an attacker substitutes a legitimate cryptocurrency wallet address with an attacker-controlled address during a transaction. This manipulation typically occurs on a user’s device, often through clipboard hijacking or malware. The user, unaware of the change, sends funds to the incorrect address, resulting in irreversible loss. This attack vector exploits the complexity and length of cryptographic addresses.
Context ∞ News in the cybersecurity and digital asset space frequently warns users about wallet address replacement scams, highlighting the importance of vigilant verification. Education on best security practices, such as double-checking addresses and using hardware wallets, is critical for mitigating this threat. The development of simpler, human-readable addresses through naming services aims to reduce the effectiveness of such sophisticated attacks.
