Etherscan Reconfigures Blockchain Explorer Settings to Filter Out Potential Scams

Etherscan has reconfigured its default blockchain viewing settings in a move to protect users against a common type of phishing scam, the company tweeted on Monday.

The blockchain explorer will now hide zero-value token transfer displays on its website by default. The setting aims to prevent users from becoming victims of "address poisoning" hacks, in which attackers send virtually valueless tokens to a user's wallet addresses to bait them into sending tokens to a scam address.

"In recent times, address poisoning attacks have phished unsuspecting users and spammed everybody else," said Etherscan. "Preventing scams and attacks in a neutral and scalable way is an infinite cat-and-mouse game."

Zero-value token transfers have drained $19 million from victims' wallets between late November 2022 and Feb. 13, 2023, according to Coinbase. To view zero-value token transfers, users will have to disable the feature in the website's setting page.
