From Crisis to Control: How to Handle a Cybersecurity Breach Efficiently

Leslie Babel • July 16, 2024

As the founder of Digital Fire, I’ve seen my fair share of cyber incidents. Let me tell you, getting hacked is no walk in the park. But with a clear, actionable plan, you can navigate through the storm and come out the other side even stronger. Based on our years of expertise, here's what I recommend:

Key Takeaways

  • Stay Calm and Document: Keep a cool head and record every action taken.
  • Alert and Isolate: Inform your team and disconnect affected systems.
  • Evaluate and Recover: Assess the damage and begin the recovery process.
  • Communicate Transparently: Inform all relevant parties about the breach.
  • Learn and Improve: Review your response and update your plans for the future. 

Stay Calm and Document Everything

Step 1: Remain Calm

First things first—stay calm. I know, easier said than done, right? I remember the first time one of our clients got hacked. It was chaos. Phones ringing off the hook, emails flying in every direction. But we took a deep breath and got to work. Your team will follow your lead, so keep cool and carry on. 

Step 2: Document Everything

Next, document every little detail. This isn't just busywork; it’s crucial for understanding what went wrong and for reporting purposes. Think of it as your own personal detective story—minus the trench coat and magnifying glass. 

Immediate Response Actions

Step 3: Alert the Appropriate People

Additionally, make sure to notify your insurance provider(s) and legal counsel as soon as possible. Their guidance and support can be crucial in navigating the aftermath of a ransomware attack.

Step 4: Take Everything Offline

Disconnect from the internet and the internal network, but don’t power off the machines. This step stops the attackers in their tracks. I’ve seen cases where shutting down a system too soon destroyed vital evidence. It’s like stopping a movie halfway through—no one likes that. 

Assess and Contain the Damage

Step 5: Hold an Emergency Meeting

Gather your team—legal, insurance, communication, and IT staff — and assign roles for investigation, recovery, and communication. This isn’t just a fire drill; it’s a coordinated effort. During one of our incidents, we found that having a clear communication plan for customers and stakeholders saved us a lot of headaches.

Step 6: Identify Compromised Systems

Investigate to find out which systems are affected. Identify the type of attack and the IP addresses involved. This step is crucial for understanding the breach and planning your next moves. Remember, knowledge is power.

Step 7: Isolate Infected Accounts or Machines

Isolate any compromised accounts or systems to prevent further spread. Think of it like quarantining a patient with a contagious disease. You want to contain the problem before it infects the whole hospital.

Step 8: Keep the Evidence:

Insurance, legal counsel, and an IT forensics company will need to access the original accounts, drives, machines, and data as it was. As you prepare for recovery, it is tempting to format, delete, and start from scratch to ensure clean systems. However, keep in mind that evidence of what happened is crucial so that an appropriate response can be crafted. If you don't have clear evidence or if during your recovery process, you destroy the evidence then you can't prove what happened. And if you can't prove what happened then the insurance company and legal counsel will have no choice but to assume the worst. And thus the response will be as if the worst hack had happened. This may involve things like rebuilding every single server, computer and system in the organization from scratch and contacting every single customer. If however, the specific scope of the incident is known, then an appropriate response can be initiated that may be more palatable than the response to a worst-case scenario.

Recovery and Clean-Up

Step 9: Evaluate the Damage

Conduct a thorough evaluation to understand the extent of the damage. Identify all entry points and backdoors used by the attackers. This will inform your recovery efforts and help you secure your systems against future attacks. 

Step 10: Begin Recovery

Activate your disaster recovery and business continuity plans. These plans will guide you in maintaining business operations and recovering lost data. Make sure everyone in your organization knows their role in this process. 

Step 11: Clean Your IT Systems

Begin the clean-up process by removing any malware or viruses and remediating vulnerabilities. Update your firewall policies and software to close security gaps. Use backups to restore your systems and create new logins for added security. 

Communication and Future Prevention

Step 12: Disclose the Breach to Necessary Parties

Inform the relevant authorities, such as law enforcement and regulatory agencies. Communicate transparently with your legal counsel, insurance companies, customers, and stakeholders. Honesty and transparency will help maintain trust and comply with legal obligations.

Step 13: Evaluate Your Performance

After resolving the immediate crisis, take time to evaluate your response. Identify any weaknesses in your plan and make necessary adjustments. Update your incident response plan and educate your employees on their roles. Continuous improvement is key to enhancing your cybersecurity posture.

By following these steps, you can manage a security breach effectively and protect your business from future threats. Stay calm, document everything, and take decisive action to secure your systems. With the right approach and expert support, you can turn a crisis into an opportunity to strengthen your cybersecurity.
