What is Ransomware?
Ransomware — Ransomware is a type of malware that encrypts a victim's files or locks their systems, then demands a ransom payment — typically in cryptocurrency — in exchange for the decryption key.
Ransomware Explained in Detail
Ransomware attacks have evolved from opportunistic "spray-and-pray" campaigns into highly targeted, multi-stage operations. Modern ransomware groups operate as businesses — complete with customer support, affiliates, and even SLAs.
Common Ransomware Kill Chain
- Initial access — Phishing email, exposed RDP, or exploited vulnerability.
- Lateral movement — Attackers move through the network, escalating privileges.
- Exfiltration — Sensitive data is stolen before encryption (double extortion).
- Encryption — Files are encrypted and a ransom note is displayed.
- Extortion — Threat to publish stolen data if ransom is not paid.
Prevention
Key defences include regular backups, network segmentation, endpoint detection and response (EDR), patch management, and employee security awareness training.
