Ransomware WannaCry is basically a worm that spreads by exploiting vulnerabilities in the Windows operating system. Once installed, it encrypts files and demands a payment to decrypt them. Ransom WannaCry is a worm that delivers a ransomware payload.

It has two primary components. A worm module used for self-propagation and a ransom module used for handling the ransom extortion activities. In WannaCry ransomware attacks, victims have been sent ransom notes with “instructions” in the form of ! Please Read Me!.txt files, linking to ways of contacting the hackers. WannaCry changes the computer’s wallpaper with messages such as asking the victim to download the ransomware from Dropbox before demanding hundreds in bitcoin to work. Once inside the system, WannaCry ransomware creates encrypted copies of specific file types before deleting the originals, leaving the victims with the encrypted copies.
