What is ransomware?

Ransomware is a type of malicious software that jeopardizes the victim’s data and perpetually blocks users access to his/her data on his/her computer, unless a ransom fee is paid.  Ransomware often infiltrates a PC as a computer worm or Trojan horse that takes advantage of one of the open security vulnerabilities.

Most of the Ransomware attacks are a result of clicking an infected email attachmentspam emails, visiting hacked or malicious websites like pornographic sitesbetting sites or random hookup sites. While some simple ransomware may lock the system in a way which is not difficult for a knowledgeable person to reverse, more advanced malware uses a technique called cryptoviral exaction. In this technique the Ransomware encrypts the victim’s files, making them inaccessible and demands a ransom payment to decrypt them. This ransomware also gives a timer in which you have to pay that amount or else they will increase the ransom amount. These days ransomware doesn’t just affect desktop machines or laptops; it also targets mobile phones.

There are two types of Ransomware?

  1. Encrypting Ransomware: It incorporates advanced encryption algorithms.It is designed to block your access to system files and demands ransom to provide you with the key that can decrypt the blocked content.
  2. Locker ransomware: – Itlocks the victim out of the operating system, making it impossible to access the desktop and any apps or files. The files are not encrypted in this case, but the attackers of ransomware still ask for a ransom amount to unlock your infected computer. Some locker versions can even taint the Master Boot Record (MBR). The MBR is the section of a PC’s hard drive which enables the operating system to boot up and keeps a track of the files on the hard drive. When MBR ransomware strikes, the boot process can’t complete as usual and prompts a ransom note to be displayed on the screen.

How does a ransomware infect your system?

  1. Spam emails is a most common way to sneak into your system. It contain malicious links or attachments.

  4. Visiting Websites that have malicious code injected in their browser or web pages.
  5. Security exploits in vulnerable software.
  6. Dropbox links, advert on web pages or by clicking hyperlink.
  7. It uses an anti-sandboxing mechanism so that the antivirus won’t detect it.
