Review Questions

• How does ransomware exemplify the evolving nature of cybercrime and the tactics used by cybercriminals?
  • Ransomware exemplifies the evolving nature of cybercrime by showcasing how attackers adapt their methods to exploit technological vulnerabilities. Unlike traditional theft, ransomware leverages encryption to lock users out of their own data, creating a sense of urgency for victims. The use of cryptocurrency for ransom payments further highlights the innovative tactics employed by cybercriminals, allowing them to operate anonymously and evade law enforcement efforts.
• What steps can organizations take to protect themselves from ransomware attacks and mitigate potential damages?
  • Organizations can protect themselves from ransomware by implementing multi-layered cybersecurity strategies, which include regular software updates, employee training on recognizing phishing attempts, and using strong firewalls. Regular data backups are crucial; they should be stored offline to prevent them from being compromised during an attack. Additionally, having an incident response plan helps organizations respond effectively if they fall victim to ransomware.
• Evaluate the implications of ransomware on society and the economy, considering both immediate effects and long-term consequences.
