FIDO2

PIN Bypass in Passwordless WebAuthn on microsoft.com and Nextcloud

We were able to bypass the PIN authentication when logging into microsoft.com. This breakes the assumption of requiring two factors and allows an attacker to log into the victim's account by using only the security key. If the security key supports NFC, the attacker could sneak up on the victim and log in without getting noticed.

Version 4 with WebAuthn/FIDO2 Support

Hardware Security SDK version 4.0.0 has been released. It supports the WebAuthn standard, which is part of the FIDO2 set of standards. Finally, we bring passwordless WebAuthn logins to Android working with security keys and smartcards over NFC and USB.
