Medical Devices Patients Rely on Most Are Least Prepared for Quantum Attacks

Post-Quantum Security Gap Leaves Healthcare IoT Devices Behind

Forescout research shows healthcare IoT and operational technology devices are far less prepared for post-quantum cryptography than conventional IT, creating major challenges for upgrading legacy medical infrastructure securely.

Medical devices patients rely on most are least prepared for quantum attacks

Threat actors are exploiting IT, IoMT, OT and IoT devices across healthcare delivery organizations (HDOs) to deploy ransomware, demand payments and monetize stolen patient data, according to Forescout’s Post-Quantum Cryptography (PQC) in Healthcare: From Data Risk to Migration Readiness report. Researchers analyzed a dataset containing more than 2.5 million devices across more than 50 HDO networks. Separately, between January and August 2026, th…

Critical IoT healthcare systems are not Quantum-Ready!

DarkReading.com reported that “IT and Internet of Things (IoT) systems across the healthcare sector appear largely unprepared for the post-quantum cryptography (PQC) era, leaving sensitive data potentially vulnerable to “harvest now, decrypt later” attacks.”  The October 6, 2026 article entitled “Critical Healthcare Systems Aren’t Quantum-Ready” (https://www.darkreading.com/iot/exposed-healthcare-systems-quantum-ready) included these comments: T…
