French is the official language in 29 countries around the world, and millions of people speak it. Jigsaw Ransomware (.fun extension) is targeted at all of those people.

The infection was created to encrypt files, and, unfortunately, it is likely to do that successfully if it gets the chance. What you want to do is strengthen your operating system’s defenses against this malware to keep it away.

That being said, we hope that you learn from this attack and remember to keep yourself and your system protected at all times.test

How does Jigsaw Ransomware (.fun extension) work?

You can identify Jigsaw Ransomware (.fun extension) by the extension is adds to the files that it corrupts. You should notice the “.fun” extension appended to .jpg, .jpeg, .raw, .tif, .gif, .png, .docx, .pdf, .xls, .avi, .mov, .mp4, and various other types of files across your entire operating system. The infection does not care about which files it affects – as long as they are not important system files – because it simply wants to back you into a corner. Once you realize that your files are “locked” and that you cannot open them normally, you should start looking for ways to restore them. At the time of research, legitimate software that could solve the problem did not exist, and decrypting these files manually is not possible, especially if you are not an expert at encryption. In the eyes of Anti-Spyware-101.com researchers, decrypting files corrupted by Jigsaw Ransomware (.fun extension) is not possible, but that is not what the creators of this infection want you to know. That is because they use this disgusting situation to blackmail you into paying money for a tool that, allegedly, could restore your file.

After the files are encrypted, Jigsaw Ransomware (.fun extension) launches a window with a timer (counts down 1 hour) and a ransom message in French. It urges the victim to pay a ransom of 300 EUR in Bitcoin. This crypto-currency is extremely popular amongst cyber attackers who need an anonymous platform to receive and realize ransom payments without getting in trouble. The note also warns that the ransom would grow if it was not paid in the given time. Where’s proof that you will get a decryptor you need to restore your files? You don’t have it, and that is why you must understand that paying the ransom would be a huge risk. We do not recommend taking it. Even if you pay, you are likely to remain stuck with your personal files locked up. If that happens, take this as a lesson to take better care of your files and your virtual security overall.
