ESET Research has published a paper detailing the discovery of a malware campaign that used repurposed commercial software to create a backdoor in computers’ firmware—a “rootkit," active since at least early 2017 and capable of surviving the re-installation of the Windows operating system or even hard drive replacement. While the malware had been spotted previously, ESET’s research is the first to show that it was actively attacking the firmware of computers to establish a tenacious foothold.
