This driver has been blocked from loading The below example shows that the blocking works (output from the "sc start" command): We also worked closely with Microsoft, so they released a block in the Windows operating system (10 and 11), so the old version of the Avast driver can't be loaded to memory. "We can confirm the vulnerability in an old version of our driver aswArPot.sys, which we fixed in our Avast 21.5 released in June 2021. The visibility enabled by the platform allowed us as researchers to capture the extent of this ransomware’s attack chain and replicate the driver file being abused to verify its function during compromise.Īvast responded to our notification with this statement: In this example using Trend Micro Vision One, the attempt was unsuccessful likely due to the product’s self-protection feature, which allowed the sensors to continue sending data and block the noted routine. However, and specific to this instance, the attempt to kill an antivirus product such as this variant’s TaskKill can also be foiled. In this case, the attackers were able to study and use Avast’s driver as part of their arsenal to disable other vendors’ security products. Once inside, the continuing trend of abusing legitimate tools and functions to mask malicious activities and actors’ presence grows in sophistication.
Similar to previously documented malware and ransomware groups, AvosLocker takes advantage of the different vulnerabilities that have yet to be patched to get into organizations’ networks. Other modern ransomware, such as Mespinoza/Pysa, modify the registries of infected systems during their respective routines to inform their victims that they have been compromised. This variant is also capable of modifying other details of the installed security solutions, such as disabling the legal notice. In addition, aside from its availability, the decision to choose the specific rootkit driver file is for its capability to execute in kernel mode (therefore operating at a high privilege).

We think the same can be said for the software deployment tool, wherein the malicious actors can subsequently decide to replace and abuse it with other commercially available ones. Enough said.While AvosLocker has been documented for its abuse of AnyDesk for lateral movement as its preferred application, we note that other remote access applications can also be abused to replace it.

Their app didn't show up in the Windows Task manager. Uninstalled it with REVO uninstaller, but not completely because, when I went to the Intel website for mobo updates, they activated themselves again and displayed an unremovable warning that I am inundated with viruses.
It is a big download and is capable of installing drivers.1 answer Top answer: I have some experience with this program, I used to work at a local repair shop that used this for installing nearly all of their drivers.
