Groupe 3R ransomware disrupts radiology services and reschedules examinations

Groupe 3R suffered a ransomware attack on April 30, 2026 that encrypted administrative data and rendered medical examination results inaccessible. Patient-care operations were materially affected, particularly on May 1 and May 2, with delays and some examinations rescheduled or redirected to other facilities. Access to historical examinations and related systems remained impaired during recovery.
