Nefartanulo Virus
A infection with Nefartanulo ransomware begins after its activation file is started on the PC. Since this process should remain unnoticed, hackers bet on various shady spread mechanisms.
All these mechanisms attempt to trick you into starting the malicious code on your system by thinking that you are starting something else. Ransomware activation files are often spread via spam emails. Spam emails that contain malicious software are often designed to resemble the emails received from various legitimate sources.
When Nefartanulo ransomware attack begins, the threat is likely to connect its command and control server and download additional malicious files needed for the following infection stages. There are several folders that are commonly used by crypto viruses to store their malicious files and objects and they are:
- %Temp%
- %Roaming%
- %UserProfile%
- %AppData%
In order to achieve a higher level of persistence, the ransomware is likely to be configured to interfere with system registries. Changes usually support the automatic execution of malicious files on each Windows OS start. By adding values under the sub-key presented below, Nefartanulo is also able to open its ransom note soon after the encryption process is done.
Since Nefartanulo virus is identified to be beased on the code of the HiddenTear project, it is likely to encode target types of files by utilizing the AES cipher algorithm. The ransomware is configured to mark all corrupted files with an extension that is the hackers’ contact email address.

- Audio files
- Video files
