Reported by more than one extremely reputable site, and though this is related to Linux, its a serious wakeup call to security vendors, regardless of the OS’s they do and don’t support. Windows actually has PAM ( Pluggable Authentication Modules ) that monitor the same services as related to Linux. Vendors and OS creators had better be on the ball with this NOW!! Not later. Below are just a handful of related sites and their reports, I am sure there are others as well.
Also related is the issue of PAM being used on YubiKey or other FIDO compliant authenticators on macOS.
