Kruu Virus Removal Guide (+Decrypt .kruu files)

Kruu – General Info

Kruu is a malicious software working as typical ransomware. Michael Gillespie, the well-known virus researcher, very first discovered this new name in the DJVU ransomware family.

Kruu was created for the sole function to encrypt all popular file types. Logically, as soon as the file encryption is successfully accomplished, the users are unable to get access to them. Kruu virus adds its own “.kruu” to all the encrypted files. For example, the file “price_list.xls”, once crypted by Kruu, will be entitled as “price_list.xls.kruu”. As soon as the file encryption is achieved, Kruu puts its own unique text file (_readme.txt) into all the folders that save the encrypted files.

The message specified by _readme.txt requesting the random os very similar to the alerts offered by other ransomware dangers belonging to the DJVU family. The warning essentially shows that the files have been secured and the only service to get access to it is to use a distinct standalone key. Regretfully, this statement is absolutely real.

The approach to encrypt the files utilized by Kruu is not completely researched. Nevertheless, there is no doubt that each computer system owner might be provided a special decryption key, which is absolutely unique. It is extremely difficult to recuperate the data without the suitable key in place.

“Don’t worry, you can return all your files!”, from text file message:

One more peculiarity of the Kruu virus is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the complete control by the criminals who have launched the Kruu infection into the internet. In order to acquire the key and bring back the essential information, the users are told to connect with the frauds through email or by telegram and to pay the ransom in the quantity of $980.

The message also states that individuals must call the Kruu authors within 72 hours upon the moment of the information file encryption. The alert indicates that by doing so the people will get a 50% discount rate, for that reason, the ransom amount drops down to $490.

No matter what the quantity of the ransom is, we strongly recommend that you do not pay the ransom. There is no warranty that these online criminals will keep their promises, so they may not care at all what the victims feel about the file encryption, even when the amount of the ransom is gotten into their accounts.

Therefore, the only appropriate choice is to bring back the data from possible backups (if offered).
