IT Risk Advisory Services: Ransomware

IT Risk Advisory Services

Ransomware Prevention, Detection and Recovery Services

Ransomware is malicious software (malware) used in a cyberattack to encrypt the victim’s data with an encryption key that is known only to the attacker (external threat agent), thereby rendering the data unusable until a ransom payment is made by the victim(1).

The ransom is usually paid in a crypto-currency because of the available anonymity for the external threat agent.

Key characteristics of modern ransomware (2)

  • Unbreakable encryption so you can’t access the files
  • File name scrambling so that you don’t know which file is which
  • Demands for payment in Bitcoin because it’s untraceable
  • Ransom demands with time limits
  • Complex evasion techniques to bypass endpoint and perimeter protection
  • Recruitment of infected PCs into a botnet to distribute malicious code
  • Capability to spread instantaneously across organizational networks
  • Data exfiltration techniques – extracting confidential data for use by cybercriminals
  • Geographical targeting – using location-specific information, such as false IRS demands in the US, so that the threat seems more troubling

An external threat agent usually gets access to your systems via

  • Social engineering/phishing
  • Exploiting a vulnerability on an internet facing application or service
