BELL Ambulance, a Milwaukee-based health care organisation, says nearly 238,000 individuals were affected by a February 2025 data breach that compromised personal, financial, medical and health insurance information. The network intrusion was detected on 13 February 2025 and disclosed on 14 April, about a month after the Medusa ransomware gang claimed responsibility; Bell Ambulance had previously said 114,000 people were impacted.
It notified the Maine Attorney General’s Office that hackers accessed its network between 7 and 14 February 2025, and has sent letters to 237,830 affected individuals. The organisation completed its investigation into the compromised information on 20 February 2026, and says the exposed data includes names, Social Security numbers, dates of birth and driver’s licence numbers, alongside financial account and medical/health insurance details.
Bell Ambulance is offering 12 months of free credit monitoring and identity protection to those affected. In March last year the Medusa group claimed theft of 219.50 GB of data and has since published allegedly stolen data, suggesting no ransom was paid, according to SecurityWeek. 11 March 2026
