Cryakl Ransomware Removal Guide

Do you know what Cryakl Ransomware is?

Cryakl Ransomware is a typical ransomware-type infection but one that needs an in-depth analysis nonetheless. From the outset, we advocate for removing this infection instead of paying the ransom that its developers want you to pay for the decryption key. The thing is, its developers might not send you the key on purpose as all they care about is making money. However, there is no way of decrypting the files using a third-party decryption tool either because it does not exist and it is unlikely that it will even do because this ransomware’s encryption is very strong.

This ransomware uses a hybrid AES and RSA encryption algorithm with a 2048-bit key length. Therefore, this encryption is very hard to break, if not impossible. While encrypting, this ransomware has been configured to add or email address to the beginning of the file name and the .cbf file extension at the end. Furthermore, it is capable of encrypting almost all file types, so this means that it can also encrypt your documents, images, videos, audio files and so on. docx, .doc, .odb, .odc, . png, .jpeg, .txt, .rar, .m4a, .wma, and .avi are just a handful of file formats that can be encrypted by this ransomware.Cryakl Ransomware Removal GuideCryakl Ransomware screenshot

Once your files have been encrypted, your desktop wallpaper will be changed to an image that acts as the ransom note. However, the note is in the Russian language so it may be unintelligible. The ransom note states the obvious — your files have been encrypted, and you need to write an email to or The ransom asks you to send one encrypted file to the cyber criminals within a week, or your files will remain encrypted forever. The criminals should also provide you with instruction on how to pay the ransom. They will most likely ask that you pay it in Bitcoins as other payment methods can be traced to the criminals.

According to our researchers, Cryakl Ransomware is set to drop its main executable either in %TEMP%, %PROGRAMFILES% or %PROGRAMFILES(x86)%. The main executable is named service.exe, but the name can be random as well. Furthermore, this malicious application will create a registry string in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run which is referred to as the point of execution. The string is named pr and its value data should look something like C:\Program Files (x86)\service.exe, for example. You have to delete these files to restore your computer’s security. However, before we get to that, let us discuss how this ransomware is distributed.

Our security analysts have discovered that Cryakl Ransomware is being disseminated via email spam. They say that the emails are disguised as business correspondence, and they contain text that says the following:
