This binary (bootmgfw.efi) is located on the ESP, according to ESET. Researchers arenвЂ™t sure yet how itвЂ™s distributed, but once ESPecter finds its way onto a PC, it begins its UEFI infection by modifying a legitimate Windows Boot Manager binary. ThatвЂ™s when its operators moved the malware from targeting legacy BIOS systems to modern UEFI systems. But development has been fairly dormant: Since then, there have only been вЂњinsignificant changesвЂќ to the code, researchers said, until last year. Interestingly, ESETвЂ™s technical analysis of ESPecter shows that its beginnings stretch back to 2012 and using Master Boot Record (MBR) modification as its persistence method. After that connection is made, attackers can commence downloading and running additional malware or executing various commands to take full control of the machine.

That driver then injects other user-mode components into specific system processes, researchers noted and those in turn are used to hook up with a command-and-control (C2) server. вЂњThis allows ESPecter to bypass Windows Driver Signature Enforcement (DSE) in order to execute its own unsigned driver at system startup.вЂќ вЂњAttackers achieve execution in the early stages of the system-boot process, before the operating system is fully loaded,вЂќ according to ESETвЂ™s ESPecter analysis, issued Tuesday. The ESP contains the boot loaders or kernel images that UEFI uses to start installed OSes and various utilities at boot time. The new malicious bootkit, which researchers at ESET have named ESPecter, camps out on the EFI System Partition (ESP) portion of the embedded technology. As such, itвЂ™s an ideal place to plant malware to ensure its persistence, since UEFI loads no matter what changes or restarts the OS goes through. The UEFI (Unified Extensible Firmware Interface) is the embedded firmware component in computing chips responsible for securing the computing environment upon startup and loading the operating system.

A rare Windows UEFI bootkit malware has been discovered, offering attackers a path to cyber-espionage, researchers are warning.ДЄccording to ESET, the bootkitвЂ™s goal is to install a full featured backdoor on a target PC, which вЂњsupports a rich set of commands and contains various automatic data exfiltration capabilities, including document stealing, keylogging and monitoring of the victimвЂ™s screen by periodically taking screenshots.вЂќ Startup Security Gets the Boot
