Physical system compromise via empty-password account
Published Jul 24, 2025 · Updated Mar 27, 2026
Empty-password authentication in Medtronic MyCareLink monitors before June 25, 2025 allows physically proximate attackers to alter functionality. A built-in user account accepts an empty password, permitting login without credentials and exposing system functions and sensitive data. Exploitation requires physical tampering with model 24950 or 24952; it enables system compromise, data access, and functionality manipulation but no direct patient harm.
