How Does Uefi Ransomware Infect

After the victim has been tricked into opening the fake e-mail attachments, the virus may immediately connect to a remote host and download the payload of Uefi ransomware.

Uefi Ransomware – Malicious Activity
Uefi ransomware is not to be mistaken with the first-ever ransomware virus, coming out with that name on March 2017 which actually attacked the UEFI of a compromised PC.
Although using the same name may be a hint that this ransomware may be created by the same people behind the original Uefi Ransomware virus, this malware has nothing to do with it.
After infection with this virus, you may find some of it’s payload files dropped under different names in the occasionally targeted Windows folders:
After dropping it’s files, the Uefi Ransowmare virus may execute them as hidden processes in Windows Task Manager. Since the files contain various functions, which are the key behind the activity of Uefi ransomware, executing them may result in the virus:
- Creating mutexes.
- Generating new types of permissions that give the virus administrative rights over your computer.
- Modify the Windows Registry Editor.
Regarding the Windows Registry Editor, the malware may take advantage of the following Windows Registry sub-keys:
- Run.
- RunOnce.
After this ransomware virus has finished it’s preparation phase it may begin to make it’s presence known on the compromised computer and change it’s wallpaper to the following image:
In addition to this, a decrypt.txt file is dropped which has the following ransom note:
Your Files Are Encrypted By Uefi Ransomware!

Uefi Ransomware – Does It Encrypt Files
At the moment, it has been established that Uefi ransomware only pretends to encrypt files, whereas in fact, the virus does not perform encryption on them. Instead, the malware aims to scare off the infected victims into paying hefty ransom fees, as reported by malware researchers on Twitter:
