What is Troj/Jigsaw-M virus?

Troj/Jigsaw-M Summary

Summarizingly, Troj/Jigsaw-M virus actions in the infected PC are next:

  • Authenticode signature is invalid;
  • Encrypting the documents located on the target’s disk drives — so the victim cannot use these files;
  • Blocking the launching of .exe files of anti-malware programs
  • Blocking the launching of installation files of anti-malware apps

Ransomware has been a headache for the last 4 years. It is hard to realize a more damaging virus for both individuals and corporations. The algorithms utilized in Troj/Jigsaw-M (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need a lot more time than our galaxy actually exists, and possibly will exist. However, that malware does not do all these terrible things immediately – it may take up to a few hours to cipher all of your files. Hence, seeing the Troj/Jigsaw-M detection is a clear signal that you need to begin the clearing procedure.

Where did I get the Troj/Jigsaw-M?

Typical methods of Troj/Jigsaw-M distribution are basic for all other ransomware examples. Those are one-day landing web pages where victims are offered to download the free app, so-called bait e-mails and hacktools. Bait emails are a pretty new strategy in malware distribution – you get the email that imitates some normal notifications about shipments or bank service conditions changes. Within the e-mail, there is a corrupted MS Office file, or a link which leads to the exploit landing site.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Avoiding it looks pretty easy, however, still requires a lot of attention. Malware can hide in various places, and it is better to prevent it even before it gets into your system than to trust in an anti-malware program. Simple cybersecurity knowledge is just an important thing in the modern-day world, even if your interaction with a PC stays on YouTube videos. That may keep you a great deal of money and time which you would spend while trying to find a fixing guide.
