Remove Tisak Virus (.Tisak Files Ransomware)

Tisak – Ransomware

The Tisak mean a ransomware-type infection. Tisak was elaborated specifically to encrypt all major file types. When the file is encrypted people are not able to use them. Tisak adds the “.Tisak” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by Tisak, will be renamed into “myphoto.jpg.Tisak“. As quickly as the encryption is completed, Tisak places a special text file into every folder containing the encrypted data.

The message given by Tisak text file asking for the ransom is definitely the same as the statements given by other ransomware representatives. It actually discusses that the info is encrypted and that the only way to bring back it is to use a a special decryption key. Unfortunately, this is definitely true. The kind of cryptography mechanism used by Tisak is still not appropriately examined. Still, it is absolutely certain that each victim may be given the specific decryption key, which is absolutely unique. It is difficult to bring back the files without the key available.

Another trick of Tisak is that the victims cannot gain access to the key. The key is saved on a specific server run by the frauds related to Tisak ransomware. To get the key and recover the important info people have to pay the ransom.

Nevertheless, irrespective of the requested amount, people need to keep away from paying the ransom. Cyber frauds are not fair, so they tend to completely disregard what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom normally does not give any positive result and people simply waste their money for absolutely nothing.

We strongly encourage that you do not contact these crooks and definitely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Tisak ransomware and to recover the information data free of charge. Thus, the only best decision is to recover the lost information from the available backup.
