Alaxione : 6,8 millions de patients revendiqués

A hacker claims to have stolen data from 6.8 million patients and over 10.1 million appointments from Alaxione, alleging a series of prior intrusions and exploitation of a pre-production environment. The hacker claims to have gained access to the data through multiple development environments, culminating in a complete database from a pre-production instance. This incident follows a pattern of data leaks dating back to 2025, including a SQL database leak in January 2026 and a CSV file in March 2025. The hacker says they alerted Alaxione two days before publishing the information and contacted journalists, receiving no response until the disclosure. The incident highlights a common challenge in cybersecurity: correlating successive data leaks to determine the scope and origin of a recent compromise.
