Two healthcare organizations have each confirmed suffering data breaches impacting more than 100,000 people after being targeted in ransomware attacks.
One of them is Milwaukee, WI-based Bell Ambulance, which provides ambulance services in the area. The company revealed last week in a data security notice that it detected a network intrusion on February 13, 2025.
An investigation showed that hackers gained access to files containing information such as name, date of birth, SSN, and driver’s license number, as well as financial, medical and health insurance information.
Bell Ambulance did not say in its public notice how many individuals are impacted, but the Department of Health and Human Services (HHS) data breach tracker revealed on Monday that 114,000 people are affected.
The Medusa ransomware group announced hacking Bell Ambulance in early March, claiming to have stolen more than 200 Gb of data from its systems.
The second healthcare organization to confirm a data breach impacting more than 100,000 people is Birmingham, AL-based ophthalmology practice Alabama Ophthalmology Associates.
Alabama Ophthalmology Associates revealed on April 10 that the personal and protected health information of current and former patients was compromised. This includes names, addresses, dates of birth, driver’s license information, SSNs, medical information, and health insurance information.
The organization detected a network breach on January 30 and an investigation showed that hackers had access to its systems since January 22.
The notorious BianLian ransomware group took credit for the attack on Alabama Ophthalmology Associates on February 19.
The HHS healthcare data breach tracker showed on Monday that the incident, based on Alabama Ophthalmology Associates’ investigation, impacts more than 131,000 individuals.
According to HHS data, more than 700 healthcare data breaches were disclosed in the US last year. The total number of records compromised across these incidents exceeded 180 million.
