The detailed disclosure PDF (88 pages) is a great read if you're interested in the gory details. The team here did excellent work and there's a lot of interesting avenues opened for future research.

"All YubiKeys running firmware prior to version 5.7—which was released in May and replaces the Infineon cryptolibrary with a custom one—are vulnerable."

I suppose I decided to start using hardware keys at the right time, I just got three 5C NFC keys and a 5C Nano this week and they're all on the newer firmware.
