Summary

In the Mira hormone monitor device firmware v1.7.1.47 build 01070147, a remote unauthenticated attacker within BLE range (approximately 10–30 meters) can silently rebind the device to an attacker-controlled account, extract stored hormone measurements in cleartext, cause a denial-of-service via malformed or undocumented command opcodes, and passively track the user via a static random BLE address that never rotates.
