Token explains how attackers can abuse authentication prompts, synced credentials, enrollment, recovery, and other trust boundaries without breaking FIDO2 cryptography. [...]","While passkeys offer enhanced security over traditional passwords, researchers have identified 39 documented methods to compromise authentication systems built around them. These attacks exploit trust boundaries in the authentication process, such as enrollment, recovery, and user verification, rather than breaking the underlying FIDO2 cryptography. SpecterOps research highlights that malware can manipulate the WebAuthn infrastructure to generate signed assertions, allowing attackers to authenticate without ever accessing the private

— not by breaking FIDO2 cryptography itself. This is critical because organizations adopting passkeys may develop a false sense of security, believing the underlying cryptographic standard alone is sufficient protection. Malware can manipulate WebAuthn infrastructure to generate signed assertions, effectively allowing attackers to authenticate without ever touching the private key. The root cause lies in misconfigured or insufficiently hardened authentication pipelines and inadequate controls around the processes that surround the cryptographic core.
