The blockchain explorer Etherscan has stopped the display of zero-value token transactions on its website by default, according to an April 10 post. Users must now explicitly activate the display from the website’s settings page. Etherscan stated that the change was designed to prevent “address poisoning” attacks that phished and spammed unwary users.

Address poisoning is a sort of cryptocurrency fraud in which an attacker sends a token with little or no value to a user’s address in order to “poison” it. Following that, the transaction is saved in the soft or hard wallet’s history and may be chosen for making transfers. The scam’s goal is to fool the victim into sending bitcoin to the scam address by accident. To do this, hackers employ sophisticated software to generate scam addresses that resemble “poisoned” addresses, with the same few beginning or ending characters.

Nonetheless, the scheme is characterized as phishing. Neither the undesirable coins nor the addresses that receive such tokens may jeopardize the cash of users. Unwanted nonfungible tokens, or NFTs, on the other hand, have the ability to compromise an address through transactions like as shifting it to multiple accounts.
