Linux-Targeting Bootkitty Appears More Proof-of-Concept Than Threat, Researchers SayCybersecurity researchers have discovered the first-ever UEFI bootkit designed to target Linux systems and subvert their boot process for malicious purposes. The "Bootkitty" malware, first uploaded to VirusTotal this month, appears to be more "proof of concept" than full-fledged threat, they said.
