Address poisoning is a common sneaky tactic—blocking-style alerts are ten thousand times more useful than regret afterward.

According to Crowdfund Insider, MetaMask has launched an address poisoning attack detection feature designed to identify scam addresses that are highly similar to the user's historical interaction addresses. The report states that address poisoning attacks typically involve sending small amounts of tokens to the user's wallet, causing the spoofed address to appear in transaction records, thereby tricking users into later accidentally copying and transferring funds. MetaMask's new feature will automatically compare pasted addresses with historical interaction addresses, and if it detects that the beginning and ending characters are the same but the middle characters differ, a blocking alert will pop up during the transaction process.
