Protect Your Business from Ransomware: Lessons from Change Healthcare

The Change Healthcare ransomware catastrophe serves as a sobering reminder of the devastating impact cyberattacks can have on businesses and critical services. With healthcare providers unable to process claims, fill prescriptions, or access critical data, the attack caused widespread disruption and financial strain.

This incident underscores the urgent need for businesses to adopt more effective cybersecurity measures, moving from a reactive "detect and respond" approach to a proactive "isolation and containment" strategy.

Key Lessons from the Change Healthcare Attack

1. Importance of Business Continuity and Disaster Recovery (BCDR) Plans: The Change Healthcare incident demonstrated that merely having backups is insufficient. An effective BCDR plan should include comprehensive data backups, recovery procedures, and regular testing to ensure preparedness for cyber incidents​.

2. Paying Ransoms Is Not a Solution: Change Healthcare reportedly paid $22 million in ransom, yet attackers retained sensitive data, exposing the company to ongoing risks and potential regulatory penalties. This illustrates that paying ransom rarely guarantees resolution and often perpetuates further extortion attempts​​.

3. Human Error and Third-Party Risks: Human error remains a primary cause of ransomware attacks. The attack on Change Healthcare, initiated through stolen credentials and lack of multifactor authentication (MFA), highlights the critical need for employee training and stringent access controls. Additionally, the heavy reliance on third-party vendors significantly increased vulnerability, emphasizing the need for robust third-party risk management​.

4. Holistic Cybersecurity Strategies: A layered security approach is crucial. This includes deploying firewalls, intrusion detection systems, data encryption, and regular employee training. Organizations must ensure that their cybersecurity measures extend beyond their immediate environment to encompass external threats and partner vulnerabilities​​.

5. Robust Endpoint Protection: One of the most effective ways to prevent such incidents is through robust endpoint protection solutions like AppGuard. Unlike traditional antivirus software that relies on detecting threats, AppGuard employs a unique "isolation and containment" strategy, preventing malware from executing in the first place.
