Comment on YubiKeys are vulnerable to cloning attacks thanks to newly discovered side channel

The attacker would need physical possession of the YubiKey, Security Key, or YubiHSM, knowledge of the accounts they want to target and specialized equipment to perform the necessary attack. Depending on the use case, the attacker may also require additional knowledge including username, PIN, account password, or authentication key.
Meh, doesn’t seem that realistic of an attack yet, but I know that could change.

To be fair given some of the places and things YubiKeys protect, especially local government, finance, hospitals, and the like, this is one of the cases where a physical attack isn’t beyond the realm of possibility.

Yeah, I was thinking that when I wrote the comment, and aimed it at people working for a smaller company or using it in their personal life, I should have been clear on this.

All they would have to do to mitigate the threat is buy new keys. The vulnerability doesn’t exist in their keys since May.
