TISAK Virus 🔐 (.TISAK Files) — How to Remove?

The Tisak virus belongs to the ransomware type of malicious agent. A harmful program of this type encrypts all user’s data on the computer (photos, documents, excel tables, music, videos, etc) and appends its own extension to every file, leaving the Tisak_Help.txt text files in each directory which contains the encrypted files.

Tisak virus: what is known so far?

Tisak will append its own .Tisak extension to every file’s name. For instance, an image named “photo.jpg” will be renamed to “photo.jpg.Tisak”. Just like the Excel table named “table.xlsx” will end up as “table.xlsx.Tisak”, and so forth.

In each directory containing the encoded files, a Tisak_Help.txt text file will appear. It is a ransom money memo. Therein you can find information about the ways of contacting the racketeers and some other remarks. The ransom note usually contains instructions on how to buy the decryption tool from the racketeers. You can get this decrypting software after contacting [email protected] by email. That is it.

How did my machine catch Tisak ransomware?

There are many possible ways of ransomware infiltration.

Nowadays, there are three most popular methods for malefactors to have ransomware working in your digital environment. These are email spam, Trojan infiltration and peer-to-peer file transfer.

• Another option for ransom hunters is a Trojan virus scheme. A Trojan is an object that infiltrates into your computer pretending to be something legal. For example, you download an installer for some program you need or an update for some service. However, what is unpacked reveals itself a harmful agent that encrypts your data. Since the update wizard can have any name and any icon, you’d better be sure that you can trust the resource of the things you’re downloading. The best thing is to trust the software developers’ official websites.
• As for the peer-to-peer networks like torrent trackers or eMule, the threat is that they are even more trust-based than the rest of the Internet. You can never know what you download until you get it. Our suggestion is that you use trustworthy websites. Also, it is reasonable to scan the directory containing the downloaded objects with the anti-malware utility as soon as the downloading is done.

How to remove ransomware?

It is important to inform you that besides encrypting your files, the Tisak virus will most likely install Vidar Stealer on your computer to get access to credentials to different accounts (including cryptocurrency wallets). That program can derive your logins and passwords from your browser’s auto-filling data.

How to avert ransomware injection?

Tisak ransomware doesn’t have a superpower, neither does any similar malware.

You can protect your PC from its infiltration in several easy steps:

• Never open any emails from unknown mailboxes with unknown addresses, or with content that has nothing to do with something you are waiting for (can you win in a lottery without participating in it?). If the email subject is more or less something you are expecting, scrutinize all elements of the questionable email carefully. A hoax letter will surely have a mistake.
• Avoid using cracked or untrusted programs. Trojan viruses are often shared as an element of cracked products, possibly as a “patch” which prevents the license check. But potentially dangerous programs are very hard to tell from reliable software, as trojans may also have the functionality you need. You can try to find information about this program on the anti-malware message boards, but the optimal solution is not to use such software.
