EUCLEAK attack allows cloning YubiKey 5 and other keys on Infineon chips
Security researchers from NinjaLab have developed a side-channel attack technique that allows cloning ECDSA keys stored in YubiKey 5 cryptographic tokens and other devices that use Infineon's cryptographic library. The attack, codenamed EUCLEAK, can be applied to many other microcontroller-based systems in addition to tokens with Infineon SLE78 chips, such as the YubiKey 5 [β¦]
