Ransomware: Prevention and Response
What is Ransomware?
Ransomware is a type of malware that locks or encrypts files and demands payment (usually in cryptocurrency) to restore access. These attacks are often triggered through malicious email links, unsecured networks, or software vulnerabilities.
Ransomware can cripple your business within minutes. Without a proper response plan, recovering from such an attack can be slow, costly, and potentially devastating.
Common Ransomware Delivery Methods
Phishing Emails
Compromised Websites
Remote Desktop Protocol (RDP) Exploits
Infected USB Devices
How to Prevent Ransomware
Backups: Regularly back up your data to secure, off-site or cloud locations.
Patch Management: Keep operating systems and applications updated to close security holes.
Access Controls: Limit access to sensitive systems using role-based permissions.
Security Software: Use up-to-date antivirus and anti-malware tools.
User Awareness: Train employees to avoid suspicious links and report incidents immediately.
What to Do If You’re Infected
Disconnect infected devices from the network.
Notify your IT support or security team immediately.
Do not pay the ransom, there's no guarantee of data recovery.
Restore data from a secure backup.
Conduct a post-incident review to improve your security.
