![]() As the tutorial images below show, this USB key provides an easy interface. With the USB key and a few minutes alone with a targeted computer, an attacker could start it up, configure it to boot from the USB key, and allow it to work its magic. This Hacking Team tutorial provides step-by-step instructions for using a USB drive to install the UEFI bootkit, which Hacking Team internally named VectorEDK, according to the leaked source code. That leaves company researchers to speculate that the attackers who installed the malicious firmware had physical access. One possibility is that the PCs received a fake UEFI update from a remote source, but there are no signs of that happening in the Kaspersky AV logs. ![]() Kaspersky Lab still doesn’t know how the bootkits came to be installed on the victim machines. This battery supplies power to the chip memory when the device is A/C powered off to retain existing BIOS settings in the chip memory. Note that BIOS setting corruption is often caused by a dead battery attached physically to the motherboard. If you have reason to believe you have BIOS based malware, you should download the latest BIOS firmware update from your device manufacturer's web site and re-flash the BIOS. There is no way Eset can physically access that area.īIOS based malware is very rare and usually is a result of a hacked BIOS firmware update. It does not scan the BIOS since those settings are firmware related and are retained in chip memory on the motherboard. The quad-core pc also has the trial EIS installed on it, and after a while running it over a few days, the bios showed up compromised again (I've since hard reset this bios on the motherboard and the computer seems to run fine for now disconnected from the internet).Įset scans the boot sectors e.g. I would gladly subscribe on both machines if that was possible.Ĭan EIS help me get my Win10 machines running again? A few days after running that initial scan, both Win10 installations had the hack-related failures I indicated above.ĮSET is the only security software I've seen that addresses the bios hack issue on my machines, and I'm hopeful that it can be used to reclaim my machines and get them working again. I ran EIS on both machined (in Win10 boot) and neither scan for either pc showed a compromised bios. The quad-core pc also has the trial EIS installed on it, and after a while running it over a few days, the bios showed up compromised again (I've since hard reset this bios on the motherboard and the computer seems to run fine for now disconnected from the internet). I'm writing this post on the Ubuntu boot of this machine. I had installed the trial EIS on the Win10 partition, and things seemed fine for a few days, but then a rogue Windows install started on the machine and I immediately hard shut it down and have not been back into the Win10 boot since. The hex-core pc is running only if I boot to Ubuntu. I also have a UEFI-bios i5 laptop that's the virus has killed at this point. ![]() I recently installed ESET Internet Security on two of my desktop pc's running Win10 in hopes that I can salvage these machines from a BIOS based hack that has brought them to their knees:ġ) a quad-core i7 with non-UEFI bios running Win10, andĢ) a hex-core i7 with UEFI bios running a dual boot between Ubuntu Linux and Win10 (dual-boot set up from Ubuntu) Please tell me if there is a better sub-forum for this post - thanks!
