Coot Virus (.coot File Ransomware) – How to Remove + Restore Data

This is a Coot virus removal guide. The article is made to help you understand what is Coot Virus, what are Coot files and how you can remove this ransomware from your computer. Shortly said, you will learn how to remove Coot virus from your PC.

Coot Virus is the name of a ransomware infection that has recently started to hit computers. At the time of writing this, there are numerous registered infections around the world. The malware aims to get into your computer system, encrypt your files and then set the .coot file extension to appear at the end of their names. The files can no longer be opened and this is the main reason why victims are extorted to pay a ransom fee to open them again. The amount of this ransom is around $1000 USD and hackers require it to be paid anonymously via BitCoin.

Read this article to learn how to remove Coot virus and how to try and get your files to work again.

Coot Virus – Update October 2019

The latest information about Coot virus ransomware indicates that the malware uses pirated software to infect computers. What happens is that victims could be downloading the following files which could lead to an infection:

  • Cracks.
  • Patches.
  • Torrents.
  • Keygens.
  • Software activators.
  • Pirated games or movies.

As of recent, the researcher Michael Gillespie (@demonslay335) has tweeted that the Coot virus is officially a variant v0175 from the STOP Ransomware virus family. The researcher has tweeted about the virus using the .coot extension and the _readme.txt note:

The tweet has sparked a lot of discussions with victims asking for solution. The sad news apparently are that this variant of STOP Ransomware may have online encryption keys. For those who are unfamiliar with this problem, STOP Ransomware variants use two types of keys for encrypting files via the AES 256 (Advanced Encryption Algorithm) cipher:

  • Offline keys.
  • Online keys.

The offline keys are easier to crack by researchers and the decryptors for the malware get updated to be able to decrypt specifically those offline keys. However, in the case of Coot ransomware and other viruses, most variants have online keys, that are significantly harder to decrypt, due to the fact that they cannot be detected and factorized as easy. We will keep track of the .coot virus situation and will have new updates and instructions in case this virus is effectively decrypted.

Coot Virus – How Did I Get It and What Does It Do?

Typical to other variants of STOP Ransomware, just like in the case of Coot Virus, the methods of infection do not differ much. These methods aim to trick you to trigger the Coot download process. The primary method being used for infection is spam e-mails that carry e-mail attachments. The attachments are in fact the virus infection file. These attachments carry around malicious macros and exploit kits that are programmed to bypass any relevant Windows and antivirus protection. Such files can pretend to be the following important documents in your inbox:

  • Invoices.
  • Receipts.
  • Order confirmations.
  • Letters from your bank.
  • Some important hospital data.
  • Ticket or hotel reservations.

Either way, when you download and run the virus, infection with Coot virus is inevitable. The virus begins to assume administrator rights and may perform the following activities on your computer:

  • Create mutexes.
  • Modify or create entries in the Windows registry entries.
  • Drop the ransom note _readme.txt and the virus files in the %AppData% or other system directories.
  • Check if its running on a real machine and if not, shuts down.

When the Coot Virus has done all its preparation processes, it is ready to start encrypting target files. It does this by scanning for your personal files, based on their type. These file types can turn out to be:

→ .JPG, .PNG, .BMP, .GIF, .PPTX, .DOC, .DOCX, .DOCM, .RAR, .ZIP, .7Z, .VM, .ISO, .AVI, .MP4, .3GP, .TIFF and other often used files.

The encryption process is very fast and your PC may slow down during these few seconds time. You will quickly notice that your files become no longer usable and get stripped out of their icons. Files, encrypted by Coot Virus begin to assume the following appearance:

For example, the file Document.txt will has the following name and look Document.txt.coot

The virus drops its _readme.txt ransom note, which contains the ransom demands of the cyber-crooks behind it:
