Ransomware has evolved from a nuisance into one of the most devastating cyber threats facing governments and institutions worldwide.
How Modern Ransomware Works
Today's ransomware operators use a multi-stage approach:
- Initial Access — Phishing emails, exposed RDP ports, or unpatched vulnerabilities
- Lateral Movement — Spreading across the network to maximize impact
- Data Exfiltration — Stealing sensitive data before encryption (double extortion)
- Encryption — Locking files and demanding payment
