The attacks require prior malware installation on the victim's device. Security analysts stress the vulnerabilities stem from weak implementation and support processes around passkeys — such as optional user verification and synced (vs. device-bound) credentials — rather than flaws in the passkey standard itself. Recommendations include enforcing server-side user verification, preferring hardware-bound keys (e.g., YubiKeys) for privileged accounts, and implementing ITDR systems to detect suspicious authenticator activity. ## Full article daily.dev links to this article rather than hosting it.
