Snippet 25: Demonstration of Bluetooth Classic Inquiry in Bastille Office

A quick real-world example from Bastille’s own office: inquiry packets flooding a conference room turned out to be the room’s computer endlessly searching for its Bluetooth keyboard. Unplugging it cleared the 2.4 GHz spectrum immediately.

Key Takeaways

• Bluetooth inquiry floods show up in ordinary offices, not just in attack scenarios
• The source was a conference room computer continuously searching for a missing keyboard
• RF monitoring with location data made the anomaly visible and fast to track down
• Even benign device misbehavior degrades the shared 2.4 GHz spectrum

Quick plug for Bastille. I was in the office the other night and noticed that we had inquiry packets in our conference room in the upper right. So I went into the room and immediately to figure out what was going on because that's strange. You don't want these inquiry floods in your environment. And it turned out, the conference room computer was looking for its keyboard. As soon as I unplugged the computer, these inquiry packets stopped and all was well in our 2.4 Ghz spectrum.
