Ransomware is one of the most damaging cyber threats facing businesses today. It encrypts your data, locks you out of your systems, and demands payment—often in cryptocurrency—in exchange for a decryption key.
For small and mid-sized businesses, the results can be devastating. Critical files become inaccessible, operations stop, and the recovery process can take days or weeks.
Attackers know that smaller organizations often lack the resources and security tools to respond quickly.
But if your business becomes a target, you are not powerless. Taking the right steps—immediately and methodically—can reduce damage, protect your data, and help your company recover faster.
What Ransomware Does
Ransomware infects systems through phishing emails, malicious links, or compromised software updates. Once inside, it encrypts files on computers, servers, and sometimes entire networks.
Common ransomware types include:
- Crypto ransomware: Encrypts data and demands payment for a decryption key.
- Locker ransomware: Locks users out of their systems completely.
- Double extortion ransomware: Encrypts data and threatens to publish it online if payment is not made.
Even if you pay the ransom, there is no guarantee you will get your data back. That is why immediate and strategic action is critical.
Step 1: Isolate the Infection Immediately
Your first move is containment. Ransomware spreads quickly across connected devices and networks. The faster you isolate infected systems, the less damage it can cause.
Take these actions right away:
- Disconnect infected computers from the network.
- Disable Wi-Fi and unplug network cables.
- Turn off shared drives and external storage devices.
- Disable remote desktop connections.
If you have a managed IT provider, contact them immediately. They can remotely isolate systems and prevent the ransomware from spreading further.
Step 2: Notify Your IT Team or Managed Service Provider
Do not try to fix the problem on your own. Alert your internal IT staff or Managed IT Services Provider (MSP) as soon as possible.
They will begin:
- Identifying the type of ransomware
- Determining the infection source
- Scanning unaffected systems for signs of compromise
- Preserving logs and evidence for analysis
Professional IT teams use forensic tools to understand how the attack occurred and what data may have been affected.
Step 3: Communicate Internally but Carefully
Keep communication controlled and organized. Inform key staff about the situation, but do not use potentially compromised channels like company email.
Use secure, offline communication methods such as phone calls or external chat platforms that are not connected to your business network.
Only authorized individuals should know details about the ransom or recovery progress to avoid confusion or misinformation.
Step 4: Assess the Damage
Once containment is in place, your IT team will evaluate the impact:
- Which devices or servers were affected
- Which data was encrypted or stolen
- Whether backups are available and clean
- Whether sensitive customer or employee data was compromised
This assessment helps determine whether you can restore data or if you need to rebuild certain systems from scratch.
Step 5: Do Not Pay the Ransom
It is tempting to pay in hopes of recovering your data quickly, but paying a ransom is never guaranteed to work.
Here is why experts, including the FBI and CISA, strongly discourage payment:
- Criminals may not provide the decryption key.
- Payment encourages future attacks.
- Your data may already be copied or sold.
- Some ransomware groups are sanctioned, making payment illegal.
Instead, focus on recovery using backups or professional decryption tools.
Step 6: Restore from Backups
If you have recent, clean backups, you can restore your systems without paying the ransom.
Follow these steps carefully:
- Verify that backups were not infected before the attack.
- Wipe infected systems completely.
- Reinstall operating systems and applications.
- Restore files from backup to clean environments.
- Reconnect systems only after testing for malware.
For businesses without reliable backups, data recovery becomes more difficult and may require professional assistance.
Step 7: Report the Incident
Reporting helps protect your business legally and may assist others in preventing similar attacks.
You should:
- Notify local law enforcement.
- Report the incident to the Cybersecurity and Infrastructure Security Agency (CISA) or the FBI Internet Crime Complaint Center (IC3).
- Contact affected clients if sensitive data was compromised.
If your business operates under compliance regulations such as HIPAA or PCI DSS, you may also need to report to regulatory bodies within a specific timeframe.
Step 8: Strengthen Security Before Reconnecting Systems
Do not reconnect to your network until your IT team confirms all traces of ransomware are gone.
After cleanup, take additional steps to prevent future attacks:
- Update all operating systems and applications.
- Change every password company-wide.
- Implement Multi-Factor Authentication (MFA) for all users.
- Review and restrict user permissions.
- Segment your network so future infections cannot spread easily.
This is also the ideal time to create or improve your incident response plan for faster action in the future.
Step 9: Review Your Backup Strategy
A strong backup strategy is your best defense against ransomware. Ensure your systems follow the 3-2-1 backup rule:
- 3 copies of your data
- 2 stored on different types of media
- 1 stored off-site or in the cloud
Use automated, encrypted backups that run daily or continuously. Test your recovery process quarterly to ensure it works when needed.
Step 10: Train Employees to Prevent Future Attacks
Most ransomware infections start with a human mistake, such as opening a phishing email or clicking a malicious link. Training employees is one of the most effective ways to reduce risk.
Your awareness program should include:
- Recognizing suspicious emails and attachments
- Verifying sender identities
- Avoiding public Wi-Fi for business tasks
- Reporting potential security incidents quickly
Frequent, short training sessions keep security awareness high and reduce the likelihood of repeat incidents.
How Managed IT Services Help You Recover and Prevent Ransomware
Working with a Managed IT Services Provider (MSP) like AIS provides both immediate support and long-term protection.
An MSP offers:
- 24/7 monitoring to detect threats early
- Automated backups and disaster recovery plans
- Patch management to close software vulnerabilities
- Incident response support during active attacks
- Cybersecurity training for employees
The Cost of Ransomware vs. the Cost of Prevention
The average cost of a ransomware incident exceeds $200,000 when accounting for downtime, data loss, and reputation damage. Prevention, on the other hand, is a fraction of that cost.
Regular updates, employee training, and reliable backups are simple, affordable steps that prevent catastrophic losses.
Next Steps: Schedule a Cybersecurity Risk Assessment
If you are unsure how prepared your business is for ransomware, start with a Cybersecurity Risk Assessment.
AIS evaluates your systems, identifies vulnerabilities, and creates a plan that includes threat monitoring, backup management, and recovery solutions.
You cannot control every threat, but you can control how ready your business is to respond.
