New Pass-ta-key attack reveals all the things we didn't know about passkeys

2026-08-12

Pass-ta-key malware can steal passkeys from an infected Windows PC using Google Password Manager. It may pose as an iPhone, then use Google's device-sync feature to copy the victim's saved passkeys. Windows lets malware access other apps' data more easily than Apple and Android systems. A malware-infected, signed-in PC can also expose passwords and active sessions.
