COOT ransomware (Decryption Steps Included) - Free Guide

What is COOT ransomware?

COOT ransomware is the strain of Djvu malware that is too new to be decrypted with freshly released Emsisoft decryption tool

The article's culprit is the newer version of the Djvu virus that was released in October, so it is not decryptable. COOT ransomware is the version of cryptovirus that demands up to $1000 for locked files when photos, documents, and video, audio files get encrypted using the RSA encryption algorithm. Although recently, the new version of the STOP virus decrypter got released, the tool helps for 148 older versions.

This Djvu virus variant appends locked files with .coot marker and is 175 variant what makes it non-decryptable. Unfortunately, when victims' files get encrypted using ONLINE keys, there is no opportunity to get data recovered by public decryption tools released in the past.

But there is a possibility that this ransomware virus is going to get a decryption utility released later on. So your first step while dealing with the malware can be storing those cryptovirus-related files on an external device for later decryption. Then you can rely on the anti-malware program suitable for proper virus termination and clean the machine.

Once core files of the ransomware get deleted, data can be replaced with backups from your archives or cloud database. You shouldn't even think about paying the ransom or contacting criminals via salesrestoresoftware@firemail.cc, salesrestoresoftware@gmail.com. There is no need to keep in contact with people that only care about profiting from you.

Cryptovirus infections are unique on their own, but when it comes to a particular family of malware, it starts to get specific. This article's culprit is the malware that, for the most part, uses the AES encryption algorithm but recently introduced the RSA method as well. This change made a huge difference in the difficulty of the file locking and left fewer opportunities for file decryption.

COOT ransomware encrypts files either using offline keys or online keys. This feature is the one that determines if the decryption tools can work or not. The offline keys are easier to crack, and those automatic tools mainly rely on this coding. Decryption tool developers can easily update the device with new offline keys and provide new victims with possible ways to fight malware.

Unfortunately, this cryptovirus and other more recent DJVU virus versions mainly rely on RSA and online keys, so it is harder to crack and decrypt. Researchers try to keep track of new releases and develop tools for possible termination. However, it takes time, so you should remove the malware and don't even think about paying the ransom.^[2]

Victims may fall for the ransom-demanding message that ransomware displays on the screen and pay the amount asked for the alleged decryption tool. We recommend staying away from the threat creators and focusing on cleaning the system.

Cryptovirus renames all personal data when encrypting it and drops a ransom note. COOT virus delivers the message with claims and offers to create trust with the victim and trick people into paying the ransom once they fall for the scammy note. However, you shouldn't believe a word found on the _readme.txt that shows the following:

The initial display of the ransom-demanding message is masking some other processes the malware runs in the background. You need to note that this family delivers additional trojans, information-stealing malware, and does that after the initial encryption.

Fortunately, you can perform an automatic COOT ransomware removal and eliminate all the additional files loaded by the cryptovirus, malware installed as a secondary payload, and even fix the alterations that came about due to scripts and programs installed or disabled.

The best tip we can give you is to rely on expert^[3] suggestions and user reviews online, official sources, and the creator website. You might need a tool like FortectIntego that can help with virus damage to further ensure that ransomware is eliminated before you recover your data.

Cryptovirus uses the RSA algorithm to make users' files useless and locked so its developers can demand the ransom.

Files with malicious script load ransomware on the system

Although the more common technique for ransomware is loading malicious documents or executables as attachments in phishing email campaigns, virus scripts can be placed on almost any type of file and hidden in packages with other data. However, infected files get placed as document attachments on spam emails as often as those malicious malware scripts get attached to pirated software installers.

This particular ransomware family is known for abusing this method while spreading versions of the cryptovirus, especially the more recent ones. Users have complained online that malware appeared on the computer after software crack installer, video game cheat code package downloads. Pirated software can be laced with anything and everything, so you should be aware of this method.

Also, this is a method widely used by many threat actors, so other malware can get installed on the system if you rely on torrent sites as the sources of your programs. Trojans, worms, and other malware can load ransomware payload on the system as a secondary payload and infect the machine further.

Make sure to terminate the malicious COOT ransomware virus with all the additional scripts

When it comes to malware that focuses on encryption like COOT ransomware virus, it is important to note that these cyber threats can run in the background without any additional symptoms and cause more damage than you think. The file marking takes attention from background processes and system folders, so cryptovirus can disable programs or add its own files to launch processes.

This is why we recommend staying away from thoughts about manual ransomware removal because you should find all the related files and programs yourself, which is barely possible without the help from anti-malware tools. Security software like SpyHunter 5Combo Cleaner, Malwarebytes should give you the opportunity to find all intruders and delete them once and for all. Finally, finish the process with FortectIntego to ensure that there is no virus damage left.

It is possible that when you decide to remove COOT ransomware, the virus interferes with the system, AV tools, and disables functions, programs that could help with the system cleaning process. This is why we included additional tips below that can help during the initial anti-malware scan.
