The mechanics behind BlackLotus UEFI bootkit.Secure Boot: An impenetrable barrier or a false sense of security?.Stay ahead of the security game with Hexnodeīefore we jump directly into all that, let’s take a closer look at the elephant (or elephants) in the room- Windows Secure Boot, and BlackLotus malware. The good news is, there are a few steps you can take to maximize the security of our computer systems. However, is there something we can do to ensure our computer systems don’t fall prey to such malware? Yes. It is also capable of disabling the security mechanisms of the operating system. For starters, a UEFI bootkit is something that is capable of infecting a computer with shadowy malware that runs in the user mode or kernel mode. The malware, called BlackLotus, is essentially a UEFI(Unified Extensible Firmware Interface) bootkit. It was the researchers from ESET, a Slovak cybersecurity company that announced the first-ever instance of malware that can bypass Secure Boot and other advanced protections in even the fully updated versions of Windows.
Hence, the emergence of a malware that can bypass Windows Secure Boot and hijack a computer’s boot process is definitely a cause for concern.
The Secure Boot feature is considered a formidable fortress for Windows-operated systems, designed to protect against boot-time malware and other threats. So to answer your question, yes it is normalish at least for me.I was having my regular morning coffee when I heard the news that a stealthy malware capable of compromising the Windows Secure Boot feature is out there now. So does dual-booting and doing something that messes with the firmware settings (turning on bitlocker for example, some bootrec commands).
Upgrading or clean installing Windows definitely does. I've not narrowed down when it does this exactly. Resumeobject path \EFI\refind\refind_圆4.efi as I don't want the Windows one.
