Easy step by step Coot ransomware removal guide
Coot is a dangerous ransomware-type infection that aims to get into computer system and encrypt the stored files and demand huge ransom payment from the victim for making the files in their original accessible condition. Basically, when you try to access the locked file, a ransom note appears on the screen whose main aim is to convince you for paying the ransom money in exchange of decryption key. This ransom note namely “_readme.txt” is stored in every folder that contains the locked files. The extension of the infected files gets changed with an additional .coot extension. For example, an infected file named as sample.jpg will get changed to sample.jpg.coot.
The Cybercriminals working behind this threat demands ransom in around $980 which is to be paid in Bitcoin or other form of Crypto currency. They offer a discount of 50% is you contact the developer within 72 hours or encryption.

Some More Techincl Details on Coot Ransomware
As of recent, Cyber researcher Michael Gillespie officially tweeted that Coot ransomware is a variant from STOP/Djvu ransomware family. For those who are not familiar with this virus family, STOP ransomware encrypts files using AES 256 algorithm with two types of keys -offline and online. Out of the two, the offline keys are easier to crack by Cyber researcher. But the problem with this variant is that the files are encrypted using online keys that cannot be easily factorized and thus it is significantly harder to decrypt.
Following to successful infiltration, Coot ransomware begins administrator rights and performs its primitive function files encryption after running a series of modules to modify window registry entries, gather data or inject viruses. For the files encryption, it uses AES 256 algorithm after scanning them by their extension. Following are the major targeted files:
.JPG, .PNG, .BMP, .GIF, .PPTX, .DOC, .DOCX, .DOCM, .RAR, .ZIP, .7Z, .VM, .ISO, .AVI, .MP4, .3GP, .TIFF and other often used files.
The ransomware changes the name of these files. All of them will receive .Coot appendix at the end of their name. Following to this, the .coot file virus creates _readme.txt file to show ransom demanding message. Here is the complete text presented on the file:

Negotiating with the Coot ransomware developers is risky. These people never provide the decryption key what they promised in the ransom note even if all their demands are fulfilled. The safe way is to remove Coot ransomware and recover the files using existing backup, if there has one been created before files encryption. The backup data should be available in some external hard-disk or in some remote storage drives. The backup in the same infected files may not work because when the rasnomware scan the hard-disk, it will encrypt the backup files as well.
Multiple sources can be used to spread ransomware
Cybercriminals are implementing various possible tactics for spreading ransomware and infect as much computers as possible. Hacked RDPs, Phishing emails, infected files, exploit kits, outdated software or just fake software program updates and cracking tools can be used as a source for computer infection. However, the most common and popular one with ransomware distribution is spam email campaign. In this, spam emails are designed and distributed. Such emails have some malicious attachments -payload dropper is spread through this way. Users are asked to open the attachments presenting as a legit and important. If opened, the payload activates and runs malicious scripts to cause malware download/installation.
