Understanding Ransomware
Ransomware is malicious software that encrypts files and demands payment for decryption. It's one of the most damaging cyber threats facing organizations today.
Common Attack Vectors
- Phishing emails with malicious attachments
- Exploit kits targeting software vulnerabilities
- Remote Desktop Protocol (RDP) attacks
- Malicious websites and drive-by downloads
Prevention Strategies
- Regular backups: Maintain offline, encrypted backups
- Patch management: Keep systems and software updated
- Email filtering: Block malicious attachments and links
- Network segmentation: Limit lateral movement
- User training: Educate staff about ransomware risks
- Endpoint protection: Deploy anti-malware solutions
- Access control: Implement least privilege principle
Incident Response
If you suspect a ransomware infection:
- Isolate affected systems immediately
- Activate incident response team
- Document everything
- Assess the scope and impact
- Do not pay the ransom (FBI recommendation)
- Restore from backups if available
- Report to authorities
- Conduct post-incident review
