Do you trust your local hospitals to keep care running during a cyberattack?
More than 115 Illinois hospitals and health systems participated Wednesday, November 4, in a statewide emergency preparedness exercise simulating a cyberattack powered by artificial intelligence. The virtual exercise, organized by the Illinois Health and Hospital Association, was titled 'Broken Trust: AI Takes Control.'
Why it matters
The simulated attack used AI to manipulate trusted information and disrupt staffing and clinical and business operations, reflecting the risk that such attacks could interrupt patient care and communications. The exercise aims to help hospitals identify weaknesses in emergency plans before a real incident occurs.
More than 115 Illinois hospitals and health systems participated in the exercise, which is described as the largest AI-focused hospital emergency preparedness exercise ever held in the state. The exercise's findings and any identified gaps in hospital readiness have not been reported.
The players
Illinois Health and Hospital Association
The Illinois Health and Hospital Association is the statewide trade association representing hospitals and health systems in Illinois, and it organized this exercise.
Tarian Group
Tarian Group is a firm whose representatives Keneatha Johnson and Stephen Weiler led the virtual training for the exercise.
The details
Hospital teams worked through scenarios testing emergency response plans, communication systems, and patient care continuity in the virtual exercise. The training was led by Keneatha Johnson and Stephen Weiler of Tarian Group and addressed responses to false AI-generated information and safe restoration of affected systems.

Cybersecurity Preparedness
The exercise extends the Illinois Health and Hospital Association's hospital emergency preparedness work into AI-powered cyber threats, testing whether hospitals can keep patient care running when trusted information is manipulated. It is positioned as preparation for a threat type that existing cyber drills may not have covered.
Patients at Illinois hospitals depend on systems that keep care, records, and communications running during an outage. The exercise is meant to reduce disruption to those services if an AI-driven attack ever reaches a hospital.
The takeaway
Hospitals and health systems can reduce the impact of cyber incidents by rehearsing how staff will keep patient care going when trusted information is compromised. Testing emergency plans before an attack is one practical way to find gaps early.
