Remove Mool ransomware (Bonus: Decryption Steps) - Free Guide

removal by Alice Woods - - | Type: Ransomware

Mool ransomware is the cryptovirus that locks files and claims to offer the potential recovery tool to trick you into paying the ransom

Mool ransomwareMool ransomware – a threat that uses encryption ciphers to make data useless on the infected system. When commonly used files get encrypted, they cannot be used or even red, so the person needs to remember if the particular data is valuable or not from the filename that also gets slightly changed. Encryption process changes the original code of the file and alters the image, document, video, or audio file, so it becomes locked. This is a version of Djvu virus that has been encryption files for a while now. Unfortunately, recent versions are not decryptable.

Then the .MOOL virus marks all the affected files using .mool file extension, hence the name of the threat. The appendix comes after the original name and extension, marking the type of particular data. Then the message with ransom demand is delivered on your machine in the text file _readme.txt with additional instructions and contact information.

Ransomware is the type of virus that affects commonly used types of files directly, but various system files, folders, and functions get affected in the background. Such behavior of the Mool ransomware virus interferes with various data recovery processes that can be possibly used for encrypted data restoring and keeps the threat more persistent when detection becomes almost impossible once AV tools and security functions get disabled. 

Name Mool ransomware
Family STOP ransomware virus
File marker .mool is the extension that appears on every encoded file and indicates encoded data in various folders
Ransom note _readme.txt is the file that developers generate after encryption and provides all the needed details there
Ransom amount The demand starts at $980, but criminals offer the 50% discount for victims who contact them in the first 72 hours. This is the trick used to fake trust between virus developers and victims, so they are more eager to pay up
Distribution Spam emails and malicious websites include malicious files with scripts triggering the drop pf a ransomware payload. The particular virus family is known for delivering such data via pirated software, cracks, cheatcodes and similar content that can be found on torrent sites and similar services

Elimination When you are thinking about ways to remove Mool ransomware, you should start with anti-malware tools that can detect[1] malware like this and delete it from the machine
Repair Even when you get rid of the virus, you need to check the system for possible virus damage and repair those issues to avoid performance problems later on. System tools like Reimage Reimage Cleaner Intego should check and repair affected system files, parts of the registry and other settings, functions for you

Previous versions in the same family were potentially decryptable with the help of STOPDecrypter, major changes got made int he encoding procedures and other processes that threats like Mool ransomware runs on the infected machine. Since encryption now is more powerful and online keys get employed previously used methods cannot be helpful for new victims. 

Some of the victims that know that their files got encoded using offline keys can use the Emsisoft decryptor for Djvu, but criminals rarely use offline IDs now. August 2019 was the last month when researchers were able to restore files easily. Unfortunately, Mool ransomware is one of the newer versions discovered[2] alongside other variants in February 2020.

Offline keys provided the opportunity to restore files for many victims once the particular ID is obtained for one of the versions. Victim keys got generated once for all the people affected by the same sample. However, developers got advanced methods and started to use proper RSA encryption[3] methods, so online keys got employed, meaning that each victims' ID is unique and randomly generated by connecting to the C2 server controlled by criminals.

So make sure to react as soon as you receive the following ransom message in the file _readme.txt that Mool ransomware developers plant in every folder with affected data:

ATTENTION!

Mool ransomware virus
Mool ransomware is the threat that can be detected by AV tools when the software is not disabled or blocked by additional processes that malware initiates in the background.
You cannot decrypt files that virus encodes on the machine, but you need to remove Mool ransomware as soon as possible, so you can avoid issues with system files and features. Ransomware starts the attack with the encryption process and when those files get affected, it can freely run in the background and inject files in system folders or disable functions of the machine that revolve around security and file restoring purposes.

Mool ransomware removal is possible with proper anti-malware tools that can detect potentially malicious programs, files that are related to harmful processes and terminate the threat completely. Make sure to choose the reliable program and trustworthy tool developer for this, so you can be sure that virus elimination is successful. 

Users shouldn't pay the demanded ransom under any circumstances. Do not consider contacting these criminals also because Mool ransomware developers can trigger other malware scripts by sending you the injected file instead of the decryption tool. This software that supposedly restores encrypted files may not even exist.

Unfortunately, anti-malware tools are not a program that does everything, so when you get rid of the Mool ransomware, you need to target the particular virus damage that can be caused by the threat in the background and affect all the possible data recovery options. To do so, you should install a reliable PC repair program or a system optimizer like Reimage Reimage Cleaner Intego and run it to check the affected or damaged parts of the machine.

Then you can worry about encrypted files and restore damaged data using your data backups or third-party recovery software that can help you. Mool ransomware can always run the secondary encryption process on newly added files, so make sure to clean the machine fully. As for encoded data, check the bonus tips and suggestions below the atticle.  Mool files virus
Mool ransomware - file-encoding malware that affects various data found on the machine, so people have no other options just to pay up for the alleged decryption tool.

Pirating and other illegal activities can lead to even more harmful malware

The more common methods used for spreading these threats like ransomware and trojans involve misleading content and silent drops of the malicious script that triggers system damaging procedures. These techniques rely on malicious files or directly infected data, websites that trigger silent worm installation.

However, this particular ransomware family is known for spreading their versions around with the help of pirating services and torrent sites. When the person goes for such a source and downloads a software package, cracks, game cheats, and similar material, malicious files can be directly injected in the installation process and drop the ransomware directly on your system.

You can avoid such infections if you stay away from these sources and other illegal activities or delete suspicious emails once received, but the infiltration process cannot be noticed, unfortunately. So once the maliciosu macros-filled document or an infected crack gets loaded ransomware attack begins. Keep AV tools on the machine to check any suspicious email attachment or installation before allowing malware on the PC.

Avoid any interaction with criminals and terminate Mool file-locking virus now

Mool ransomware virus is the threat that encrypts files and demands payments from victims, but you shouldn't even consider that option because contact between you and any cybercriminal can cause more serious issues regarding the security state of your device and even privacy. Since paying cannot ensure that you will get your files back this is the way to lose your data and money at the same time.

You need to remove Mool ransomware without even thinking about paying the ransom, so your device is not permanently damaged by this threat. Get SpyHunter 5Combo Cleaner, or Malwarebytes, and clean the system from any traces of malware, potential threats, and remote tools of the malicious attackers. 

Mool ransomware removal process should also be followed by a proper system check that is focused on damage and file repairing. AV tools not supposed to tackle virus damage, so rely on system optimizers or cleaners like Reimage Reimage Cleaner Intego. Then you can sure that virus damage is eliminated and you can freely restore encrypted data. If you need additional tips for that – check below.
