Fake AI trading agent steals crypto wallet passwords

Attackers built a website for a fake AI crypto trading agent and used it to install Needle Stealer, malware that replaces a victim’s browser wallet with a copy that sends the wallet password to the attacker. HP caught the campaign between April and June 2026. The Needle campaign targets people who download AI agents from search results or ads, and users of seven browser wallet extensions, among them MetaMask, Coinbase Wallet and Phantom.
