What is Ransomware? 
Ransomware is a sophisticated piece of malware that blocks the victim’s access to his/her files, and the only way to regain access to the files is to pay a ransom.
There are two types of ransomware in circulation:
  1. Encryptors, which incorporates advanced encryption algorithms. It’s designed to block system files and demand payment to provide the victim with the key that can decrypt the  blocked content. Examples include CryptoLockerLockyCrytpoWall and more.
  1. Lockers, which locks 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 still ask for a ransom to unlock the infected computer. Examples include the police-themed ransomware or Winlocker.
  1. Some locker versions infect theMaster Boot Record (MBR). The MBR is the section of a PC’s hard drive which enables the operating system to boot up. When MBR ransomware strikes, the boot process can’t complete as usual and prompts a ransom note to be displayed on the screen. Examples include Satana and Petya families.
Crypto-ransomware, as encryptors are usually known, are the most widespread ones, and also the subject of this article. The cyber security community agrees that this is the most prominent and worrisome cyber threat of the moment.











May 12th 2017 saw the biggest ever cyber attack in Internet history (yes, bigger than the Dyn DDoS).  A ransomware named WannaCry stormed through the web, with the damage epicenter being in Europe.

In the first few hours, 200,000 machines were infected. Big organizations such as Renault or the NHS were struck and crippled by the attack.
Ransomware has been a growing trend for the past two years, and this is just a culmination, a grand reveal to the wider world of just how big of a threat it is. But we’ve been writing about this for a while now.
Some time ago, a delivery guy walked into our office. While we signed for the package, he realized that we work in cyber security and asked:
My entire music collection from the past 11 years got encrypted by ransomware.
WannaCry leveraged a vulnerability in Windows OS, first discovered by the NSA, and then publicly revealed to the world by the Shadow Brokers.


Ransomware has some key characteristics that set it apart from other malware:
  • It feature sunbreakable encryption, which means that you can’t decrypt the files on your own (there are various decryption tools released by cyber security researchers – more on that later);
  • It has the ability to encrypt all kinds of files, from documents to pictures, videos, audio files and other things you may have on your PC;


  • It can scramble your file names, so you can’t know which data was affected. This is one of the social engineering tricks used to confuse and coerce victims into paying the ransom;
  • It will add a different extension to your files, to sometimes signal a specific type of ransomware strain;
  • It will display an image or a message that lets you know your data has been encrypted and that you have to pay a specific sum of money to get it back;
  • It requests payment in Bitcoins because this crypto-currency cannot be tracked by cyber security researchers or law enforcements agencies;



  • Usually, the ransom payments have a time-limit, to add another level of psychological constraint to this extortion scheme. Going over the deadline typically means that the ransom will increase, but it can also mean that the data will be destroyed and lost forever.
  • It uses a complex set of evasion techniques to go undetected by traditional antivirus (more on this in the “Why ransomware often goes undetected by antivirus” section);
  • It often recruits the infected PCs into botnets, so cyber criminals can expand their infrastructure and fuel future attacks;

  • It can spread to other PCs connected to a local network, creating further damage;
  • It frequently features data exfiltration capabilities, which means that it can also extract data from the affected computer (usernames, passwords, email addresses, etc.) and send it to a server controlled by cyber criminals; encrypting files isn’t always the endgame.
  • It sometimes includes geographical targeting, meaning the ransom note is translated into the victim’s language, to increase the chances for the ransom to be paid.
