What Type of Malware Is the Ransomware

Ransomware in general has been a growing trend with infection and particularly effective. It prays primarily on those users who do not have a backup of their important files. The Ransomware encrypts your important documents, music, videos, pictures, archives and other data, making them no longer effective. The files cannot be opened after they have been attacked by the Ransomware and they have the .krab extension added to their names.

Faktisk, the infections with ransomware, just like have become so massive that you can be sure that at the moment somebody somewhere in the world is either opening a suspicious spammed e-mail attachment, believing it is legit or clicking on a malicious web link.

But the ransomware can also be spread completely automatically, similar to the WannaCry virus which was spread via a worm infection, causing the data of over 200,000 computers to be encrypted. The creators of ransomware who are involved in this act as if they have nothing to lose and do not mess around. They have invested a lot in their attacks and organized them so that as many inexperienced users as possible become victims.

In addition to this, the GANDCRAB V4.1 ransomware also adds a ransom note file to extort victims into paying the ransom. The note, is called KRAB-DECRYPT.txt and has the following contents:
