Change Healthcare recently reported "Change Healthcare Cyberattack", a noteworthy cybersecurity incident.

A cyberattack on Change Healthcare in 2024 disrupted patient care and cost hospitals billions, exposing critical vulnerabilities such as the lack of multi-factor authentication and encryption.

The disruption is felt across the environment, and exposing Medical data, plus an estimated financial loss of Billions (hospitals).

Formal response steps have not been shared publicly yet.

The case underscores how teams are taking away lessons such as Critical vulnerabilities in healthcare cybersecurity, including lack of multi-factor authentication and encryption, must be addressed to prevent future disruptions, and recommending next steps like Adopt mandatory multi-factor authentication, encryption, and establish grants for cyberattack preparedness and response planning. Improve coordination among federal agencies and develop a comprehensive incident response plan.

Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.

The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.
