Tisc Virus Removal Guide (+Decrypt .tisc files)

Tisc Virus – Details

Tisc is a malicious software application functioning as common ransomware. Michael Gillespie, the well-known virus researcher, first found this new name in the DJVU ransomware family.

Tisc was created for the sole purpose to encrypt all popular file types. Realistically, as soon as the encryption is successfully achieved, the users are not able to get access to them. Tisc ransomware adds its own “.tisc” to all the encrypted files. For instance, the file “price_list.xls”, as soon as modified by Tisc, will be entitled as “price_list.xls.tisc”. As soon as the encryption is achieved, Tisc puts its own unique text file (_readme.txt) into all the folders that keep the encrypted files.

The alert specified by document asking for the random os very similar to the notices offered by other ransomware threats belonging to the DJVU family. The caution basically shows that the files have 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 utilized by Tisc is not entirely researched. Nevertheless, there is no doubt that each computer owner might be issued an unique decryption key, which is absolutely special. It is incredibly difficult to recover the information without the appropriate key in place.

“Don’t worry, you can return all your files!”, from _readme.txt message:

One more peculiarity of the Tisc infection is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the complete control by the scoundrels who have launched the Tisc ransomware into the world wide web. In order to obtain the key and restore the crucial data, the users are told to connect with the scams through email or by telegram and to pay the ransom in the quantity of $980.

The message likewise states that individuals must get in touch with the Tisc authors within 72 hours upon the moment of the data encryption. The alert shows that by doing so individuals will acquire a 50% discount rate, therefore, the ransom amount falls to $490.

No matter what the quantity of the ransom is, we highly recommend that you do not pay the ransom. There is no guarantee that these online scoundrels will keep their promises, so they might not care at all what the victims feel about the file encryption, even when the quantity of the ransom is received into their accounts. For this reason, paying ransom frequently does not lead to an effective recovery. So, the users might merely lose their money for nothing.

For that reason, the only right decision is to bring back the data from possible backups (if available).
