What is Tisc Ransomware
Tisc is one of many ransomware versions issued by the STOP/Djvu family. Just like older versions, Tisc Ransomware encrypts PC-stored data and demands crypto ransom for unique decryption software that will unlock this data. Most often, malware like Tisc will scout through the available files and block access to the most valuable ones. The list of such usually consists of images, music, videos, and documents containing important information. After locating these files, the file-encryptor will write strong cryptographic algorithms over the targeted files to prevent users from manually approaching their decryption. Victims infected with this ransomware version will see their data changed with the .tisc extension. This means a compromised file like
1.pdf will change to something like
1.pdf.tisc. Then, Tisc developers set up their virus to create the _readme.txt file that features decryption guidelines.

They say victims can recover the data only by paying for a special decryption kit (a tool and key) stored by the developers. Unfortunately, this is the only way to decrypt files unless ransomware contains some serious vulnerabilities that help third-party tools crack open the ciphers. Despite this, your files can be recovered in case you possess backup copies held on virtual (cloud) or physical (USB) storage. In all other cases, the decryption of Tisc files is hardly possible unless the aforementioned. The cost of decryption offered by cybercriminals is 980$, but can be reduced down to 490$ if victims contact developers within 72 hours after getting infected. Communication between victims and ransomware developers is written to be established via one of the e-mail addresses (email@example.com or firstname.lastname@example.org). In addition to that, frauds behind Tisc Ransomware and the entire STOP/Djvu family offer the victims to send 1 file with no valuable information for free decryption. This is why ransomware developers will prove their capability of decrypting your data. Unfortunately, whatever they do to elevate their trust and push victims into performing the requested steps is still not enough to be 100% sure about their trustworthiness. Just like other fraudulent figures, they may be able to fool you and not send any decryption tools even after paying the ransom. If you do not have money to pay the ransom, or simply do not want to risk your money, we recommend using backup copies as mentioned above. It is also possible some victims do not have very important data encrypted, so they can afford to lose it without regrets. However, if you are the opposite case and willing to decrypt your data without having any backup copies, you can give it a try nonetheless. Along with removal instructions, we have prepared a list of the most popular and effective tools able to decrypt compromised data in some scenarios down below.

How to protect computer from viruses, like Tisc Ransomware, in future
1. Get special anti-ransomware software
Use ZoneAlarm Anti-Ransomware
Famous antivirus brand ZoneAlarm by Check Point released a comprehensive tool, that will help you with active anti-ransomware protection, as an additional shield to your current protection.
