Rankiteo Explanation : Attack with significant impact with customers data leaksDescription: Ascension Michigan notifies some of its patients of a data breach that happened between Oct. 15, 2015, and Sept. 8, 2021. It noticed suspicious activity in its electronic health record and upon investigation found that an unauthorized individual accessed its patient information. The compromised information included full name, date of birth, address(es), email address(es), phone number(s), health insurance information, health insurance identification number and medical records, Social Security numbers. The Ascension Michigan offered free credit and identity theft protection-monitoring services to the affected patients. | |||||||
| Ascension | Breach | 100 | 5 | 5/2025 | ASC220051225 | Link | |
Rankiteo Explanation : Attack threatening the organization's existenceDescription: Ascension, one of the largest private healthcare systems in the United States, experienced a data breach that exposed the personal and healthcare information of over 430,000 patients. The incident, disclosed in April, involved a data theft attack impacting a former business partner in December. Attackers accessed personal health information related to inpatient visits, including physician names, admission and discharge dates, diagnosis and billing codes, medical record numbers, and insurance company names. Personal information such as names, addresses, phone numbers, email addresses, dates of birth, race, gender, and Social Security numbers were also compromised. The breach was linked to a vulnerability in third-party software used by the former business partner, likely part of widespread Clop ransomware attacks. | |||||||
| Ascension | Ransomware | 100 | 7 | 6/2024 | ASC1012070724 | Link | |
Rankiteo Explanation : Attack that could injure or kill peopleDescription: Ascension faced a ransomware attack resulting in severe disruptions across 140 hospitals, implicating patient care and treatment schedules. The recovery was hindered by the need for 'assurance' letters to reconnect systems with suppliers, adding to the operational chaos. The impact extended to canceled appointments and surgeries, and pushed medical staff to revert to manual processes. The organization's swift action towards transparency and reconnection of supplies post-attack mitigated prolonged delays. | |||||||
