Address poisoning attacks in cryptocurrency involve malicious actors deceiving users into sending funds to fake addresses resembling legitimate ones. Through techniques such as phishing, transaction interception, and smart contract manipulation, attackers exploit human error rather than technical vulnerabilities in blockchain networks. This manipulation led to over $83 million in confirmed losses. Key measures to avoid these attacks include using fresh wallet addresses for each transaction, employing hardware or multisig wallets, and regularly updating wallet software. Users are also advised to be cautious when sharing their public addresses and to adopt blockchain analytics tools to identify suspicious activities. Real-world examples showcase the dangers, including significant financial losses from scams involving zero-value transfers and poisoned addresses on popular networks. The consequences not only result in theft but also erode user trust in the security of blockchain technology, impacting overall network efficiency.
