Sermo’s Data Breach Investigation
Sermo, a knowledge platform connecting healthcare professionals globally, recently disclosed a data breach after an unauthorized actor, identified as the Black Basta ransomware group, gained access to its network. The breach occurred between March 19, 2024, and April 10, 2024, following a power outage at Sermo’s data center in Denmark, which led to the discovery of the incident.
Upon learning of the suspicious activity on April 10, 2024, Sermo immediately took action to secure its network and retained cybersecurity professionals to investigate the breach. The investigation revealed that the ransomware attack involved the unauthorized access and acquisition of files from Sermo’s systems.
Black Basta took responsibility for the attack and later posted the stolen data on its dark web leak site. Sermo made multiple attempts to download the data, but due to the slow nature of the leak site, it wasn’t until September 20, 2024, that the full dataset was downloaded. The data was eventually removed from the site on January 27, 2025.
Sermo’s investigation into the leaked data confirmed that the personal information of several individuals was impacted, including the Social Security numbers of five Maine residents. Although Sermo has stated that there is no evidence of identity theft or fraud as a result of the breach, they are offering identity monitoring services to affected individuals as a precautionary measure.
When Did This Breach Occur?
The breach occurred between March 19, 2024, and April 10, 2024. The suspicious activity was detected on April 10, 2024, with the full data being downloaded by September 20, 2024. The data was no longer accessible after January 27, 2025, when Black Basta’s leak site was taken down.
What Information Was Breached?
The information that may have been compromised includes:
Sermo has emphasized that while medical records or detailed health information were not specifically mentioned, there may have been health-related data accessed as part of the breach. However, Sermo believes that identity theft or fraud has not occurred from this data breach as of now.
