The World's First Unkillable UEFI Bootkit For Linux


An anonymous reader quotes a report from Ars Technica: Over the past decade, a new class of infections has threatened Windows users. By infecting the firmware that runs immediately before the operating system loads, these UEFI bootkits continue to run even when the hard drive is replaced or reformat...

Researchers at security firm ESET said Wednesday that Bootkitty -- the name unknown threat actors gave to their Linux bootkit -- was uploaded to VirusTotal earlier this month. Still, Bootkitty suggests threat actors may be actively developing a Linux version of the same sort of unkillable bootkit that previously was found only targeting Windows machines. [...] As ESET notes, the discovery is nonetheless significant because it demonstrates someone -- most likely a malicious threat actor -- is pouring resources and considerable know-how into creating working UEFI bootkits for Linux.
