CC10 – Building a Ransomware Incident Response Plan
Step 1: Set Up Defense Systems
Build strong defenses to reduce risks and speed up recovery. These measures help ensure quick detection and containment of threats.
Write Your Response Plan
Create a detailed response plan that includes:
- Emergency contacts: List key personnel, their roles, and contact details.
- Response procedures: Outline clear steps for containment and recovery.
- Communication templates: Prepare pre-approved messages for stakeholders.
- Recovery priorities: Highlight critical systems that need immediate attention.
- Decision authority: Define the chain of command for making critical decisions.
Set Up and Test Backups
Having dependable backups is essential for recovery. Stick to these guidelines:
- Encrypt backups: Use encryption to protect all backup data from unauthorized access [1].
- Follow the 3-2-1 rule: Maintain three copies of your data, store them on two different media types, and keep one copy offsite.
- Test regularly: Schedule monthly test restorations to ensure backup integrity.
| Backup Type | Storage Location | Testing Frequency |
|---|---|---|
| Primary | Local encrypted storage | Weekly |
| Secondary | Cloud-based solution | Bi-weekly |
| Tertiary | Offsite physical storage | Monthly |

Train Staff on Security Basics
Educate your team to:
- Spot and report suspicious emails.
- Use safe browsing habits.
- Create strong and unique passwords.
- Handle sensitive data responsibly.
- Report any security concerns without delay.
Step 2: Spot and Assess the Attack
Detecting and understanding a ransomware attack quickly is essential for limiting the damage. Recognizing the signs and determining the extent of the breach will help you plan your next steps effectively.
Look for Warning Signs
Be alert for these key indicators of a ransomware attack:
| Warning Sign | What to Check | Urgency Level |
|---|---|---|
| File Access Issues | Problems opening files, strange file extensions | High |
| System Behavior | Sluggish performance, unexpected reboots, odd pop-ups | High |
| Network Activity | Unusual outgoing traffic, encrypted connections | High |
| Storage Changes | Sudden disk usage spikes, missing files | High |
| User Reports | Locked screens, ransom notes, encrypted files | Critical |
Use system logs and security tools to monitor activity. If you notice antivirus alerts or disabled security features, investigate immediately. Once you confirm these signs, move on to assessing the extent of the attack.
Check Which Systems Are Hit
Understanding which systems and data are compromised will shape your response. Here’s how to start:
1. Run Network Scans
Perform a thorough network scan to identify affected devices. Record all compromised IP addresses and hostnames for your response team.
2. Inspect Critical Systems
Focus on your most essential systems first:
- Database servers
- File shares
- Email systems
- Backup storage
- Domain controllers
This will help you prioritize containment efforts.
3. Document Everything
Keep a detailed record of:
- Encrypted files and their locations
- Affected user accounts
- Disabled security tools
- Impacted business applications

Step 3: Stop the Spread
Once you’ve assessed the attack, your next move should be to contain the damage by isolating the affected systems.
Here’s how you can do that:
- Disconnect infected devices: Remove them from all networks to prevent the issue from spreading to other systems.
- Separate backup systems: Unplug backups from the primary network and double-check their integrity to ensure they’re not compromised.
- Keep detailed records: Log action timestamps and assign responsibilities to team members for accountability and tracking.

Step 4: Remove the Ransomware
Get rid of ransomware using reliable methods and tools.
Identify the Ransomware Type
Start by figuring out which ransomware variant has infected your system. Look at encrypted file extensions, the ransom note, system behavior, and the types of files targeted.
Tools like ID Ransomware or Crypto Sheriff can help pinpoint the exact strain. Knowing this is key to choosing the right removal approach.
Use Removal Software
Here’s how to tackle the ransomware:
- Boot in Safe Mode: Restart your computer in Safe Mode with Networking to stop the ransomware from running during the cleanup process.
- Update Your Security Software: Make sure your antivirus and anti-malware tools are fully updated with the latest definitions.
- Run a Full System Scan: Perform a deep scan using the updated tools to locate and remove the ransomware.
For businesses, services like Computer Mechanics Perth offer professional-grade tools and expert assistance to safely remove malware while protecting important data.
After the scan is done, double-check to ensure no traces of the ransomware remain.
Verify Your System Is Clean
Once the removal process is complete, confirm that your system is free of any lingering infections.
Check this by monitoring system performance, reviewing network activity, verifying file integrity, and running additional scans. This ensures your system is fully restored and secure.
Step 5: Restore Systems and Data
Once the threat is removed, the next step is to get your systems and data back up and running.
Load Clean Backups
Carefully restore backups to avoid any chance of reinfection:
- Check the integrity of your backups to ensure they haven’t been tampered with.
- Focus on restoring the most critical systems and data first.
- Test by restoring a small set of data in isolation to confirm everything works as expected.
Use an isolated network segment during the restoration process to keep potential threats contained. After restoring, double-check the data to confirm it’s complete and accurate.
Verify Data Accuracy
Make sure the restored data matches its pre-attack state. Use tools like file checksum checks, database tests, and functionality validations to confirm everything is in order.
Once you’re confident in the data, it’s time to reinforce your security measures.
Strengthen Security Measures
Before fully resuming operations, take steps to improve your defenses:
- Apply all software updates and patches.
- Reset passwords and credentials across the board.
- Enable advanced monitoring tools.
- Segment your network to better protect critical systems.
For ongoing security, consider using services like Computer Mechanics Perth. They offer managed IT solutions, including continuous system monitoring, automated backups, and threat detection to help protect your network from future attacks.
Finally, conduct a thorough security assessment before returning to normal operations. Regular updates and active monitoring will ensure your systems remain secure.
Step 6: Tell Everyone Who Needs to Know
Once the threat is under control and recovery efforts are underway, it’s time to communicate promptly and effectively.
Share key details about the incident, such as:
- Timeline: When the incident occurred and how it was discovered.
- Compromised Data: What types of information may have been affected.
- Scope: The number of impacted individuals or records.
- Actions Taken: Steps implemented to control the situation and address its effects.
- Recovery Status: Progress on restoring systems and mitigating risks.
