Ransomware recovery enables businesses to restore essential data and systems without paying the ransom, minimizing financial losses and operational disruptions. Without a solid recovery strategy in place, ransomware attacks can cripple operations, compromise sensitive data, and cost companies millions.
While prevention is best, every organization needs a plan B. This article will guide you through the steps of ransomware recovery to help protect business-critical data and operations. While we hope you never need to implement these measures, being prepared can make all the difference in the face of an attack.
What Is Ransomware Recovery, and Why Does It Matter?
Ransomware recovery is the process of restoring systems and data after a ransomware attack without paying the ransom. It involves a series of steps to regain control of your systems and restore data. This process is crucial for maintaining business continuity and protecting your organization’s assets and reputation.
A recent report highlights the importance of an effective recovery strategy: only 63% of organizations successfully restore their data after a ransomware attack—even though 92% of them have backups. That means almost 1 in 4 companies will lose their data and be forced to negotiate with the hackers. And even if they pay up, there is no guarantee that the organization will get their data back.
What Does a Ransomware Recovery Plan Include?
A ransomware recovery strategy needs to be a well-planned, tested, and efficient process that can be quickly implemented in a crisis. This includes:
- Backup systems
- Data restoration
- Communication plans
- Legal and compliance considerations
- Post-incident analysis and learning
How To Recover From a Ransomware Attack
Ransomware attacks can be devastating, but with the right approach, recovery is possible. Whether you’re using a specialized solution like ProLion DataDefense or following manual recovery steps, here’s a guide to help you navigate the process:
DataDefense by ProLion is the easiest, fastest, and best way to prevent and recover from ransomware. It continuously monitors your storage systems, detecting and blocking unusual activities in real time.
1. Use DataDefense for quick and efficient recovery (Recommended)
If an attack does manage to get through (such as via an insider threat), DataDefense’s Single File Restore feature allows you to pinpoint and restore only the affected files in one click. This is much faster than restoring the entire system.
Plus, DataDefense’s comprehensive data access transparency enables you to trace exactly what changes were made, when, and by whom. This makes it easy to figure out which files you need to restore.
If you don’t have DataDefense, here’s what you need to do:
2. Isolate and Contain the Threat
Immediately disconnect all infected systems from the network to contain the ransomware. This includes turning off Wi-Fi, unplugging Ethernet cables, and disabling Bluetooth on affected devices. If possible, disconnect network storage devices and external hard drives. For cloud-based systems, revoke user access and change authentication credentials. This containment step is crucial to prevent the ransomware from spreading to other systems or backup stores.
Tip: Check out our guide to ransomware containment to learn how to stop ransomware spreading through your system.
3. Assess the Damage and Identify the Ransomware Strain
Conduct a thorough inventory of affected systems, applications, and files. Look for ransom notes or changed file extensions to help identify the specific ransomware strain. You might need to use ransomware identification tools or consult with cybersecurity experts. Understanding the type of ransomware will inform your recovery strategy and help prevent future incidents.
Tip: Document everything for later analysis and potential legal or insurance purposes.
4. Report the Incident
You might need to notify relevant authorities, especially if personal data of customers and employees has been compromised. It’s a good idea to get legal guidance first to understand reporting obligations. At this point, you’ll also want to contact your cybersecurity insurance provider, if you have one.
5. Communicate with Stakeholders
Clear communication is crucial during a crisis. Inform employees about the situation and provide guidance on necessary precautions. Notify affected customers and partners as required by law or contracts. Be transparent about the incident, but avoid sharing sensitive details that could compromise the recovery efforts or ongoing investigation.
All external communications should be carefully considered and approved by legal counsel to avoid making the situation worse.
6. Restore from Clean Backups
To restore from your backups, you’ll first want to verify their integrity. Use offline or air-gapped backups if available, as online backups are more likely to have been compromised.
Checking your backups is crucial to ensure you’re not reintroducing malware or using corrupted data.
Begin by locating your backup files and checking their timestamps to ensure you’re using versions from before the ransomware attack. Next, use file integrity verification tools to confirm that your backup files haven’t been corrupted or tampered with and then mount the backups in an isolated, sandboxed environment to inspect their contents without risking your clean systems. Then run a thorough malware scan on the mounted backups to ensure you’re not accidentally reintroducing the ransomware into your system.
Once you’ve verified your backups, start by restoring the most critical systems and data first.
Tip: Hackers often target backups because they know working backups are essentially your get-out-of-jail free card. Check out our guide to learn how to protect your backups from ransomware.
7. Conduct a Post-Incident Review
After recovering your data, a comprehensive post-incident review is crucial. This review should aim to identify how the attack succeeded and what vulnerabilities were exploited. Analyze system logs, interview staff involved, and if possible, examine the initial infection vector.
8. Strengthen Security Measures
Once you’ve identified the root cause, it’s time to ramp up your ransomware prevention to ensure it doesn’t happen again. Your specific actions will depend on the nature of the attack.
For example, if the ransomware entered through a phishing email, focus on enhancing your email security and offer staff regular cybersecurity training. If the attack stemmed from an access issue, consider strengthening your access controls like multi-factor authentication (MFA) and the principle of least privilege.
Remember, improving your cybersecurity is an ongoing process. By addressing the specific vulnerabilities exploited in the attack, and any other vulnerabilities, you can improve your organization’s resilience against future ransomware incidents.
Tip: While these steps can help in recovery, ProLion DataDefense can significantly simplify and expedite the process, providing better protection and faster recovery in the event of an attack.
