Found on VirusTotal: The world’s first UEFI bootkit for Linux
arstechnica.com
“Bootkitty” is likely a proof-of-concept, but may portend working UEFI malware for Linux.

“Whether a proof of concept or not, Bootkitty marks an interesting move forward in the UEFI threat landscape, breaking the belief about modern UEFI bootkits being Windows-exclusive threats,” ESET researchers wrote. “Even though the current version from VirusTotal does not, at the moment, represent a real threat to the majority of Linux systems, it emphasizes the necessity of being prepared for potential future threats.”

    Yes, failing to safeguard keys is fatal, but that applies to everything. But if fs you’re storing keys on is behind luks and they’re readable by root only - you’re as safe enough. There’re also LSMs like selinux that can increase the complexity of attack.

    I don’t know about nitrokey specifically, but TPM is an option (not good enough, imo) and a simple luks encrypted usb. You could get some convenience by storing the key to unlock it somewhere on the encrypted root.

    In general - you cannot stop a targeted attack no matter what, but staying safe from all the automated ones is doable.
