[QUOTE="bazang, post: 1100792, member: 114717"] The Yubikeys with firmware prior to 5.7.0 are still safe to use. Even if someone has physical access to the key, it requires an extremely high level of sophisticated knowledge and experience to accomplish the attack. Specialized equipment and tools are needed too. Yubikeys probably have more undiscovered vulnerabilities because of the same thing - few researchers possess the wherewithal to vuln hunt the devices. While unfortunate that such a vuln exists, it is illogical to replace older keys with the vuln. I would not. The only exception is where I know I use a system targeted by nation-state threat actors and that system processes, stores or transmits data at a high sensitivity level. [/QUOTE]
