Two-factor authenticationTwo-factor authenticationPosted Sep 3, 2011 11:00 UTC (Sat) by Cato (subscriber, #7643)In reply to: Two-factor authentication by job Parent article: kernel.org compromised
I found this from 2 years ago - replay attack due to a bug in the Yubico authentication server, since fixed by Yubico: http://www.grennan.com/?p=113
It's up to the authentication server to do the right checks, so perhaps some authentication servers have bugs.
I'd like to see more on this claimed replay attack, too.
