Craa was created for the sole purpose to encrypt all popular file types. Logically, as soon as the file encryption is effectively achieved, the users are not able to get access to them. Craa virus adds its own “.craa” to all the encrypted data. For instance, the file “price_list.xls”, once modified by Craa, will be titled as “price_list.xls.craa”. As soon as the encryption is achieved, Craa puts its own special text document (_readme.txt) into all the folders that save the encrypted files.
The alert mentioned by _readme.txt requesting for the random os very similar to the notices given by other ransomware dangers belonging to the DJVU family. The caution basically indicates that the information has been encrypted and the only service to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely real.
The method to secure the files used by Craa is not totally researched. Nevertheless, there is no doubt that each computer owner might be released an unique decryption key, which is absolutely distinct. It is exceptionally difficult to recuperate the information without the appropriate key in place.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Craa 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 crooks who have released the Craa infection into the world wide web. In order to acquire the key and restore the essential information, the users are informed to connect with the frauds by means of email or by telegram and to pay the ransom in the quantity of $980.
