The Palo Alto report showed attacks that, it said, “demonstrate how malware on a compromised endpoint can misuse onboarding, recovery and device trust workflows to take over passkey-protected accounts,” as well as “how an attacker can authenticate without user interaction, bypass user verification requirements and extract all synced passkey private keys.”
Palo Alto described three categories of attack, collectively dubbed Pass-ta-key: Pass-ta-key, where an attacker takes over an account protected by a Google-synced passkey using malware running on the victim’s device, without requiring privilege escalation, device unlock or user interaction; Silver Pass-ta-key, which involves an attacker tricking Google Cloud Authenticator into believing the victim has unlocked the device with biometrics, leading to full account takeover without using the victim’s device during authentication; and Golden Pass-ta-key, which allows an attacker to extract all synced passkeys in a form that lets them be shared or sold on the credential black market.
Given the complexity of most global enterprise threat surfaces, some CISOs have struggled with adapting passwordless processes to environments with legacy and virtual environments. Passcodes have been recently embraced by enterprise CISOs as the first step in implementing a passwordless strategy.
