Medical File listed on killsec leak site

The Mexico-based healthcare software company Medical File has been listed on a leak site by the threat actor known as killsec. The announcement, which was made on February 20, 2025, follows a claimed attack that occurred on the same day. This development marks a significant incident for the organization, as the threat actor has publicly declared their intent to release stolen information if specific conditions are not met.

Details of the alleged attack

According to the claims made by killsec, the group has successfully gained unauthorized access to the networks belonging to Medical File. The threat actor asserts that they have obtained approximately 500 GB of data during this intrusion. While the group has not disclosed the specific amount of the ransom demand, they have stated that they will proceed to publish the stolen data if the organization fails to meet their demands.

In an effort to demonstrate the validity of their claims, the group has shared some data samples as part of the announcement. These samples appear to consist of documents that are representative of the sensitive information handled by the company. The group has indicated that they expect the organization to engage in negotiations regarding the situation. This pattern is common in modern cyberattacks, where threat actors use public pressure to force a victim into a dialogue.

Data and affected information

The information disclosed in the announcement suggests that the breach involves highly sensitive documentation. Based on the screenshots provided by the threat actor, the data appears to include various types of medical and clinical records. The specific types of data identified in the listing include:

• Medical records
• Clinical reports

The presence of such information highlights the sensitive nature of the breach, as these documents are central to the operations of a healthcare technology provider.

About Medical File

Medical File is a technology platform that provides digital clinical record management and healthcare data solutions. It operates as an innovative electronic patient record system in the market, serving as a critical component for managing healthcare data and digital clinical records.

Risk assessment and industry implications

This alleged breach may pose a significant risk due to the potential inclusion of sensitive patient data within the healthcare sector. The exposure of such data may lead to privacy violations and secondary risks such as identity theft. Furthermore, the organization could face legal obligations under Mexican data protection regulations due to the nature of the information involved.

The killsec group is noted for having hacktivist origins and providing ransomware-as-a-service. Because of this profile, it is assessed that they may be inclined to utilize double-extortion tactics. Double extortion is a method where attackers not only encrypt a victim's data to disrupt operations but also steal the data beforehand to threaten its public release, thereby increasing the pressure to pay the ransom.

In such scenarios, organizations often face the necessity of conducting a comprehensive forensic investigation to determine the full scope of the data breach. Such investigations are vital for understanding how the perimeter was breached and what specific datasets were accessed. For organizations operating in the healthcare sector, maintaining robust security postures is essential to protect patient privacy and comply with regional data protection laws. Defensive measures typically involve continuous monitoring, strict access controls, and regular security audits to mitigate the risk of unauthorized network access and subsequent data exfiltration.
