What is ViiperWaRe Ransomware?
ViiperWaRe Ransomware is a file-encrypting malicious program created according to an open-source ransomware known as Hidden Tear. After carefully researching it, our researchers came to a conclusion, the malware might be still just a test version, so it is difficult to say whether users can come across it at the moment of writing. If you wish to know more, we invite you to read the rest of our report as we will explain what makes us think the infection is not yet fully developed. Of course, if ViiperWaRe Ransomware ever gets upgraded it might be useful to know how it could affect your system or how it could be erased. For this reason, we are adding step by step deletion instructions at the end of the text too.
Where does ViiperWaRe Ransomware come from?
Provided ViiperWaRe Ransomware is spread at all, the malicious program should enter the system after launching some suspicious data received from torrent or other unreliable P2P file-sharing networks, Spam emails, and so on. Therefore, the threats installer could be any recently downloaded file if it was launched just before the computer got infected. In order to guard the computer against such malware in the future, our researchers at Anti-spyware-101.com recommend installing a legitimate antimalware tool. Not just to check suspicious data before launching it, but also as an extra precaution because the tool can warn the user about various malicious threats. Besides a trustworthy security tool, we could suggest staying away from untrustworthy web pages, potentially dangerous programs, suspicious pop-up ads, Spam emails, etc.
How does ViiperWaRe Ransomware work?
The sample tested by our researchers targeted a single directory called %USERPROFILE%\Desktop\test. The name of the targeted folder suggests this current ViiperWaRe Ransomware variant might be just a test version released to see if the software works the way it is intended to. After testing our sample, we came to a conclusion the malware can encrypt pictures, photos, music files, videos, text or other documents, and some other data types. Plus, it looks like each encrypted file should be marked with an additional extension, e.g., picture.jpg.viiper, so if the infection manages to enter the system and ruin any files, the user should be able to identify such data immediately.
Furthermore, right after ViiperWaRe Ransomware encrypts its targeted data it should open a pop-up window. The message on it explains why the user might be unable to open his data, why it happened, and how to recover it for a suggested price. The interesting part is that there is a box allowing to change the text’s language. Even though it does not work at the moment, this might mean the malicious program’s creators intended to develop an infection they could distribute widely. Another thing we noticed while looking at the described pop-up window is that the hackers ask for a payment of €20,000. As you realize it yourself, probably no one would risk losing so much money even if the encrypted files were irreplaceable. Again, the large sum no one would be likely to pay shows the ransomware could still be being tested. The good news is you do not have to lose your files or risk your savings if you come across the test version. Our researchers say the data can be decrypted and we will explain how it can be done in the next paragraph.
How to eliminate ViiperWaRe Ransomware?
If your system was somehow infected with ViiperWaRe Ransomware, you may want to try to restore files that could have been encrypted afterward. In which case you should know it has to be done before removing the malware since later on it might be impossible to do this. The test version of this malicious program provides a decryption key you can submit to the pop-up window and unlock all encrypted data. We will explain how to do this in more detail in the deletion instructions you can find below this article. They will tell how to get rid of the ransomware manually too, although if you prefer erasing it with automatic features, we advise you to install a legitimate antimalware tool instead.
