Ransomware Attack Response Playbook
Purpose:
This playbook provides guidelines for an effective response to ransomware attacks, aimed at minimizing damage, facilitating recovery, and preventing future incidents.
Scope:
The procedures apply to all organizational units impacted by ransomware, detailing steps from initial detection to recovery and post-incident analysis.
Team Roles and Responsibilities:
- Incident Response Manager: Leads the response efforts, ensuring coordination across teams.
- Security Analysts: Conduct initial investigations, malware analysis, and assist in containment and eradication.
- IT Support: Manage system isolation, data restoration, and ensure continuity of IT operations.
- Communications Officer: Responsible for internal and external communications regarding the incident.
- Legal/Compliance Officer: Address legal and compliance issues, including data breach notifications and interaction with law enforcement.
Phase 1: Identification
- Detection Tools: Utilize endpoint detection and response (EDR) tools, antivirus programs, and network monitoring to identify signs of a ransomware infection.
- Alert System: Implement automated alerts for suspected ransomware activity to ensure rapid response.
- Employee Reporting: Encourage employees to report suspicious activity or inaccessible files immediately.
Phase 2: Containment
- Network Isolation: Disconnect infected systems from the network to prevent the spread of ransomware.
- Account Disablement: Temporarily disable affected user accounts to limit access to network resources.
- Traffic Segmentation: Use firewall rules and segmentation to isolate network segments impacted by the attack.
Phase 3: Eradication
- Malware Removal: Employ specialized tools to remove ransomware from infected systems. Confirm the removal with multiple scans.
- System Cleanse: Wipe and reformat hard drives where the ransomware was active to eliminate any traces of the malware.
Phase 4: Recovery
- Data Restoration: Restore data from backups that are confirmed to be free of ransomware. Test restored data to ensure it is intact and malware-free.
- System Reintegration: Gradually reintegrate cleaned systems into the network, monitoring for signs of lingering issues.
- Continuity Measures: Implement interim solutions to maintain business operations during the recovery phase.
Phase 5: Post-Incident
- Root Cause Analysis: Investigate how the ransomware entered the network, and identify any security weaknesses that were exploited.
- Lessons Learned: Hold a debriefing session to gather insights from the incident, documenting outcomes and recommendations for strengthening security.
- Regulatory Compliance: Ensure compliance with relevant regulations by reporting the incident to necessary authorities and affected parties if required.
- Awareness Training: Enhance ransomware awareness and training programs to educate employees about preventive measures and the importance of security hygiene.
Tools and Resources Needed:
- Endpoint detection and response (EDR) tools
- Antivirus and anti-malware software
- Network security appliances (firewalls, IDS/IPS)
- Data backup and recovery solutions
- Secure communication platforms for incident management
