Hello,

<div class="ContentPasted0">I hope everyone is doing well!</div>

<blockquote style="margin-top:0;margin-bottom:0">
<div class="ContentPasted0 ContentPasted1">A new vendor-independent Microsoft Windows UEFI rootkit named Black Lotus was recently discovered being advertised on underground criminal forums for $5,000 and $200 per new version.
<div><br class="ContentPasted1">
</div>
<div class="ContentPasted1">This new UEFI rootkit can execute malicious code before the booting process completes, bypassing secure boot and user access control (UAC), and disabling security features such as BitLocker and Windows Defender. Then, it is able
to load unsigned drivers and achieve persistence at the UEFI level with Ring 0 on the infected device.</div>
<div><br class="ContentPasted1">
</div>
<div class="ContentPasted1">Black Lotus is a very lightweight payload (80kb) written in C and assembly with anti-VM, anti-debugging, and geolocation filtering capabilities – to avoid infecting countries in the CIS (Commonwealth of Independent States) region.
It provides fully featured tasking and file transfer, as well as several capabilities to operate undetected.</div>
<div><br class="ContentPasted1">
</div>
Considering Black Lotus' capabilities, it is worrying that a UEFI rootkit is available on underground forums, allowing threat actors to operate stealthily on a low level.<br>
