What is Ransomware in Cybersecurity?
Malware that encrypts a victim's files or locks their system and demands payment (usually cryptocurrency) for the decryption key. Modern ransomware groups also steal data and threaten to publish it (double extortion). Ransomware spreads through phishing, exposed RDP, and supply chain compromises.
Why Ransomware Matters for Your Cybersecurity Career
Ransomware is the most financially destructive cybersecurity threat facing organizations today. Incident responders handle ransomware events as their highest-priority cases. SOC analysts monitor for ransomware indicators like mass file encryption and C2 traffic. CISOs must build ransomware preparedness programs including offline backups, tabletop exercises, and incident response retainers.
