Xbtl was created for the sole purpose to encrypt all popular file types. Rationally, as soon as the encryption is successfully accomplished, the users are unable to get access to them. Xbtl ransomware adds its own “.xbtl” to all the encrypted files. For instance, the file “price_list.xls”, as soon as crypted by Xbtl, will be titled as “price_list.xls.xbtl”. As soon as the encryption is accomplished, Xbtl puts its own unique text document (_readme.txt) into all the folders that keep the encrypted files.
The message mentioned by document asking for the random os very comparable to the notices provided by other ransomware threats coming from the DJVU family. The caution essentially shows that the information has been secured and the only option to get access to it is to use a special standalone key. Regretfully, this declaration is definitely real.
The method to encrypt the files utilized by Xbtl is not totally looked into. However, there is no doubt that each computer system owner may be issued an unique decryption key, which is definitely special. It is very difficult to recover the information without the appropriate key in place.

One more peculiarity of the Xbtl infection 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 crooks who have released the Xbtl virus into the internet. In order to acquire the key and bring back the important information, the users are informed to get in touch with the frauds through email or by telegram and to pay the ransom in the amount of $980.
