First-Ever UEFI Rootkit Tied To Sednit APT

First-Ever UEFI Rootkit Tied To Sednit APT
Researchers hunting cyber-espionage group Sednit (an APT also known as Sofacy, Fancy Bear and APT28) say they have discovered the first-ever instance of a rootkit targeting the Windows Unified Extensible Firmware Interface (UEFI) in successful attacks.

From a report: The discussion of Sednit was part of the 35C3 conference, and a session given by Frederic Vachon, a malware researcher at ESET who published a technical write-up on his findings earlier this fall [PDF]. During his session, Vachon said that finding a rootkit targeting a system's UEFI is significant, given that rootkit malware programs can survive on the motherboard's flash memory, giving it both persistence and stealth.

'UEFI rootkits have been researched and discussed heavily in the past few years, but sparse evidence has been presented of real campaigns actively trying to compromise systems at this level,' he said. The rootkit is named LoJax. The name is a nod to the underlying code, which is a modified version of Absolute Software's LoJack recovery software for laptops. The purpose of the legitimate LoJack software is to help victims of a stolen laptop be able to access their PC without tipping off the bad guys who stole it. It hides on a system's UEFI and stealthily beacons its whereabouts back to the owner for possible physical recovery of the laptop.
