Medusa Ransomware Group Has Attacked 500+ Critical Infrastructure Orgs

When the cybersecurity advisory was first issued in March 2025, the authorizing agencies determined that Medusa had conducted more than 300 attacks on critical infrastructure entities between 2021 and February 2025.

CareCloud Data Breach Affects 3.75 Million Individuals
When we last reported on the CareCloud data breach in early August, it was starting to become clear from breach notifications to state attorneys general that the cybersecurity incident involved a major breach of patient data. The scale of the breach was difficult to determine, as many state attorneys general do not make data breaches affecting state residents public, and of those that do, only a few state how many individuals have been affected. The data breach has now been added to the HHS’ Office for Civil Rights breach portal, showing that this was one of the largest healthcare data breaches of the year, involving unauthorized access to the electronic protected health information of 3,756,469 individuals. While CareCloud has confirmed that a threat actor claimed to have stolen sensitive data, no threat group appears to have publicly claimed responsibility for the attack.
