THE DJI ROMO ROBOVAC HAD SECURITY SO POOR, THIS MAN REMOTELY ACCESSED THOUSANDS OF THEM

Summary from the TLDR InfoSec newsletter

A security researcher found that DJI's Romo robot vacuum lacked MQTT authentication, allowing any client to connect to DJI's servers and pull telemetry from roughly 7,000 devices across 24 countries. Live camera feeds, microphone access, 2D floor plans, and serial numbers were all available. In under 9 minutes, the researcher cataloged over 6,700 devices and collected more than 100,000 MQTT messages, revealing precise home layouts and approximate device locations via IP geolocation. DJI has reportedly closed the immediate access gap. Still, the deeper problem remains: the device-to-cloud channel trusts any authenticated session as a legitimate owner, a fundamental IoT authorization failure.
