UNM Health

A cyberattack detected October 26, 2026 knocked out electronic systems across UNM's Health Sciences Center, diverting ambulances for two hours and canceling surgeries and appointments. UNM says the intruder reached only end-user devices, never core servers; how it got in, and whether patient data exited, goes unsaid. Byod, a new ransomware group, claims 36,000 systems and Cerner EHR rosters. Even with its core intact, the hospital stopped, because the failure domain was the desktop, and the desktop ran the clinic.
