Password compromise via unrestricted API brute force
Published Dec 4, 2025 · Updated Dec 8, 2025
Improper authentication throttling in Medtronic CareLink Network before December 4, 2025 allows remote attackers to determine valid passwords. An API endpoint permits repeated unauthenticated web requests to test passwords without sufficient restriction, though Medtronic has not disclosed the exact endpoint or limiting logic. No account is required, and successful exploitation exposes valid credentials and user information within the non-medical service without directly controlling implanted devices.
