Implantable Cardiac Device Wireless Attack Range Simulator (2D)

Pacemakers and implantable defibrillators exchange telemetry with an external programmer over a short-range radio link, and how far away that link can be intercepted is pure RF physics — a log-distance path-loss model, not guesswork. This 2D top-down simulator lets you drag an attacker marker anywhere on a floor-plan map around a patient with an implanted device, live-computing the received signal strength and capture probability at every position while an orange ring marks the real −85 dBm detection-range boundary, and a companion graph plots the exact RSSI-vs-distance curve for the current transmit power. Toggling AES-128 telemetry encryption shows the actual security consequence: with encryption on, captured frames are unreadable ciphertext and a replay attack fails; with it off, a captured command can be re-sent and accepted by the implant, exactly the class of vulnerability behind real FDA safety advisories on implantable device firmware.
