Deep dives
Yubikey Vulnerability and Implications
A significant vulnerability has been discovered in Yubikey devices, where a cloning attack can exploit a cryptographic flaw in the microcontroller used in these keys. All models in the Yubikey 5 series are especially vulnerable, making it possible for someone to clone the key with physical access, although the process requires specialized equipment costing around $11,000. As a consequence, users are unable to update the firmware to address this vulnerability, leaving them at risk unless they purchase new keys. Nevertheless, the actual threat level is considered low for most users, especially those employing additional authentication measures, as high-resource attackers are uncommon.
