Etherscan, a blockchain researcher, has updated its website to disable the default display of zero-value token transfers, as announced on April 10 post. Users must now manually activate the display on the settings page. The update is aimed at preventing “address poisoning” attacks, in which a token with zero or near-zero value is sent to a user’s address in order to “poison” it. Scammers then use sophisticated software to create fake addresses that look like poisoned addresses to trick users to send coins to wrong addresses. Although this scam is classified as phishing, it cannot jeopardize user funds. However, unwanted unplayable tokens (NFTs) can potentially compromise addresses through interaction.
Etherscan conceals token transfers with zero value as a preventative measure against address poisoning attacks.
