This article explains the issues that occur in case of infection with Nefartanulo ransomware and provides a complete guide on how to remove malicious files and how to potentially recover files encrypted by this ransomware.
Nefartanulo Ransomware
Nefartanulo is a ransomware infection that is developed to damage computer system settings and personal files. It utilizes a strong cipher algorithm to transform target files and leaves them completely inaccessible. The ransomware is also set to extort a ransom payment for the decryption of .nefartanulo@protonmail.com files. For the extortion, it drops a file called HOW_TO_RECOVER_ENCRYPTED_FILES.txt and places it in a place where you cannot miss it. Sometimes ransomware loads automatically their ransom messages. Hackers attempt to blackmail you into paying a ransom for the decryption of files encrypted by the Nefartanulo virus. Paying this ransom to hackers is highly inadvisable as there is no guarantee that they will act as they promise.
Check out more details about Nefartanulo ransomware and find out how to remove it completely from the infected PC.

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. For example, the file image.jpg will be renamed to imaje.jpg.nefartanulo@protonmail.com. The following files may no longer be accessible:
- Audio files
- Video files
- Document files
- Image files
- Backup files
- Banking credentials, etc
After encryption, the file HOW_TO_RECOVER_ENCRYPTED_FILES.txt will appear on the system. It contains the Nefartanulo’s ransom message. All it states is:

Apparently, hackers don’t want to reveal the exact amount of money they demand to exchange the decryption tool for .nefartanulo@protonmail.com files. If there is something sure, it is that they will want to transfer the amount in cryptocurrency. Beware that paying the ransom does not guarantee the recovery of your encrypted files so we advise you to attempt to fix the problem with the help of available alternative solutions.
