  9. 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. • Two types of ransomware in circulation: • Encrypting Ransomware - which incorporates advanced encryption algorithms to lock victim out of files. Examples include CryptoLocker, Locky, CrytpoWall and more. • Locker ransomware, which locks the victim out of the operating system, making it impossible to access the desktop and any apps or files.  • Some locker versions can even infect the Master Boot Record (MBR). • Examples include Satana and Petya families.

  10. Key Characteristics of Ransomware • Unbreakable encryption • Ability to encrypt all kinds of files • Scramble your file names • Add a different extension to your files • An image or a message (ransom note) • Requests payment in Bitcoin • The ransom payments have a time-limit • Uses a complex set of evasion techniques • Often recruits the infected PCs into botnets • Can spread to other PCs connected to a local network • Frequently features data exfiltration capabilities
