Kuub is a malicious software working as common ransomware. Michael Gillespie, the widely known virus researcher, first found this new name in the DJVU ransomware family.
Kuub was created for the sole function to encrypt all popular file types. Rationally, as quickly as the encryption is effectively achieved, the users are unable to get access to them. Kuub virus includes its own “.kuub” to all the encrypted files. For instance, the file “price_list.xls”, once crypted by Kuub, will be titled as “price_list.xls.kuub”. When the file encryption is achieved, Kuub puts its own special text file (_readme.txt) into all the folders that store the encrypted files.
The message stated by _readme.txt requesting for the random os really similar to the notices offered by other ransomware risks coming from the DJVU family. The warning basically indicates that the information has been encrypted and the only service to get access to it is to use a special standalone key. Regretfully, this declaration is absolutely real.
The technique to secure the files utilized by Kuub is not entirely looked into. However, there is no doubt that each computer owner may be provided an unique decryption key, which is absolutely unique. It is extremely difficult to recover the information without the suitable key in location.
One more peculiarity of the Kuub virus is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the complete control by the criminals who have introduced the Kuub infection into the internet. In order to acquire the key and bring back the essential data, the users are told to connect with the frauds via email or by telegram and to pay the ransom in the amount of $980.
The message also states that individuals must call the Kuub authors within 72 hours upon the minute of the data encryption. The alert suggests that by doing so individuals will get a 50% discount rate, for that reason, the ransom amount drops down to $490.
