Ransomware

An overview of ransomware, its risks, protective measures, and real-life examples.

Ransomware is a type of malicious software (malware) that is designed to encrypt a victim's files or lock them out of their computer system, rendering their data inaccessible. The attackers then demand a ransom payment from the victim in exchange for providing the decryption key or unlocking the system.

Protection

General recommendations

  1. Regular backups: Maintain regular backups of critical data and systems. Make sure backups are stored offline or in a secure, isolated environment to prevent them from being compromised during an attack. Test your backups periodically to ensure they can be restored successfully.
  2. Update software: Keep your operating systems, applications, and security software up to date. Many ransomware attacks exploit known vulnerabilities in outdated software.
  3. Network segmentation: Segment your network to limit the lateral movement of attackers. This can help contain the impact of a ransomware attack.
  4. Incident response plan: Develop and regularly update an incident response plan that outlines the steps to take in case of a ransomware attack. This can help minimize the impact and recovery time.
  5. Least privilege: Follow the principle of least privilege, ensuring that users have only the necessary permissions to perform their tasks. Limiting privileges can mitigate the impact of a ransomware infection.
  6. Employee training: Train employees on how to identify and report suspicious emails, links, and attachments. Regularly test employees with simulated phishing exercises to reinforce training and identify areas for improvement.
