Medical Management, Inc.

Medical Management, Inc., operating under the alias MMI, is an organization headquartered in the United States specializing in healthcare administration services. Its core operations involve handling electronic claims processing, a critical function within the healthcare payment system. This service necessitates the management of sensitive data, specifically protected health information (PHI) and health insurance details belonging to patients. The nature of this work places MMI within the healthcare sector, acting as a processor or administrator facilitating transactions between healthcare providers and insurers. Handling such regulated data subjects the organization to stringent compliance requirements concerning data security and privacy.

The organization gained public attention due to a significant cybersecurity incident. On November 3, 2020, MMI fell victim to a ransomware attack perpetrated by the Maze Team threat actor group. This attack involved not only the encryption of systems but also the confirmed exfiltration of sensitive electronic claims processing files containing PHI and health insurance information. The attackers publicly disclosed the stolen data on their dedicated leak site, demonstrating unauthorized access and exposure of patient records. Despite clear evidence of this sensitive data breach, MMI did not issue any public statements acknowledging the incident, file regulatory breach notifications, or communicate directly with affected individuals. Furthermore, the organization did not respond to external inquiries regarding its breach response efforts, leaving its handling of the incident undocumented in the public domain. This event underscores the critical data security responsibilities inherent in MMI's role processing healthcare claims.
