Xcvf – Ransomware
Xcvf is a malicious software application working as typical ransomware. Michael Gillespie, the well-known malware researcher, first discovered this new name in the DJVU ransomware family.
Xcvf was developed for the sole purpose to encrypt all popular file types. Rationally, as quickly as the encryption is successfully accomplished, the users are not able to get access to them. Xcvf virus adds its own “.xcvf” to all the encrypted data. For example, the file “price_list.xls”, as soon as crypted by Xcvf, will be titled as “price_list.xls.xcvf”. When the encryption is accomplished, Xcvf puts its own special text document (_readme.txt) into all the folders that keep the encrypted files.
The alert stated by _readme.txt requesting the random os very similar to the alerts given by other ransomware dangers coming from the DJVU family. The warning essentially shows that the files have been encrypted and the only option to get access to it is to use a distinct standalone key. Regretfully, this declaration is absolutely real.
The approach to secure the files utilized by Xcvf is not totally researched. Nevertheless, there is no doubt that each computer owner may be issued an unique decryption key, which is definitely special. It is extremely hard to recuperate the data without the suitable type in place.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Xcvf ransomware is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the total control by the crooks who have launched the Xcvf ransomware into the internet. In order to get the key and bring back the important information, the users are told to connect with the frauds through email or by telegram and to pay the ransom in the amount of $980.
The message likewise says that the people ought to contact the Xcvf 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 quantity drops down to $490.
