Vlff Virus – Details

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

Vlff was developed for the sole purpose to encrypt all popular file types. Rationally, as quickly as the file encryption is effectively accomplished, the users are unable to get access to them. Vlff virus adds its own “.vlff” to all the encrypted data. For instance, the file “price_list.xls”, as soon as crypted by Vlff, will be titled as “price_list.xls.vlff”. When the encryption is achieved, Vlff puts its own unique text file (_readme.txt) into all the folders that save the encrypted files.

The message stated by text file requesting the random os very similar to the notifications offered by other ransomware threats belonging to the DJVU family. The caution basically indicates 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 used by Vlff is not totally researched. However, there is no doubt that each computer system owner might be provided a special decryption key, which is absolutely unique. It is incredibly difficult to recuperate the data without the suitable key in location.

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

Don't worry, you can return all your files! virus

One more peculiarity of the Vlff infection 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 crooks who have introduced the Vlff ransomware into the web. In order to acquire the key and bring back the important data, the users are informed 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 individuals must get in touch with the Vlff authors within 72 hours upon the moment of the data file encryption. The alert suggests that by doing so the people will obtain a 50% discount, therefore, the ransom quantity falls to $490.

No matter what the amount of the ransom is, we strongly advise that you do not pay the ransom. There is no assurance that these online criminals will keep their pledges, so they might not care at all what the victims feel about the encryption, even when the amount of the ransom is gotten into their accounts. Hence, paying ransom typically does not result in an effective recovery. So, the users might just lose their money for nothing.

Likewise, we prompt you not to contact the scams as they advise. Do not move money into their wallets. There are no applications that might split the Vlff ransomware or bring back the information at no cost. Therefore, the only correct decision is to restore the information from possible backups (if available).
