This program promised to remove the limitation to mine cryptocurrencies in the RTX 30. It was malware

  • 16

In the middle of last year, NVIDIA announced that it would reduce the ETH hash rate of its new batch of graphics cards. In a nutshell, using LHR (Low Hash Rate), the company reduced graphics performance when mining cryptocurrenciessomething designed to deter miners and encourage the arrival of GPUs in the gamer market.

This was quite a blow to miners (although NVIDIA already had an alternative, CMP) and, as expected, programs promising to get rid of this limitation have not been long in appearing. One that has been talked about this week is RTX LHR Unlocker and, to no one’s surprise, it turned out to be malware.

The software, called “Nvidia RTX LHR v2 Unlocker” and developed by a certain Sergey, allegedly installed a modified BIOS on the RTX 30 and A-series RTX to remove performance limiters. As if this were not enough, the developer also stated the following on the project’s GitHub page, now removed:

“Modifying the BIOS is not enough to completely hack your graphics card […] You also need the graphics drivers modified by me. They are automatically downloaded and installed in Windows when the program is installed […].

That is to say, that it modified the BIOS and installed modified graphics drivers from a private server to, in principle, unleash the full mining potential of graphics previously capped by NVIDIA. However, the reality was that the software not only did he not do what he promisedbut infected powershell.exe with malware.

As we can see in Joe’s SandBox Cloud and detail in Tom’s Hardwarethe malware checks system drives, performs evasive loops to make analysis more difficult, uses code obfuscation techniques, and causes very high CPU usage. Malware behavior can be seen from this website.
