Sniffing and Controlling Unpaired Bluetooth Low Energy (BLE) Devices

This hands-on post shows how to sniff, analyze, and actively control unpaired Bluetooth Low Energy (BLE) devices using low-cost hardware: a Sonoff Zigbee 3.0 USB Dongle Plus (CC26x2-based) re-flashed as a BLE sniffer with NCC Group’s Sniffle, and a Nordic nRF52 USB mini dev board to connect and write to GATT characteristics. Because many cheap gadgets don’t use pairing/bonding, their ATT/GATT traffic is unencrypted;...

🔧 Technical Details

Off‑path BLE connection sniffing for unauthenticated control: When devices don’t pair/bond, GATT is cleartext. Use a CC26x2 Sonoff re-flashed with Sniffle to follow connections and filter Wireshark on _ws.col.info contains "Sent Write Command" to identify the exact handle/value pairs that trigger actions (e.g., handle 0x0b, values 0x01/0x00).

Replay/control via generic BLE clients: After learning the t...

🤖 Agent Actions

I analyzed the blog and the HackTricks repository and found that while there is an existing BLE page (in Radio Hacking), it lacked practical content on off-path BLE sniffing with Sniffle, Wireshark triage filters, and active control via Nordic tools with automation (blatann). I updated the existing BLE page to include this hands-on exploitation workflow, preserving all existing content and structure.

What I did:

• Explored repository structure and relevant files:
  • src/todo/radio-hacking/pentesting-ble-bluetooth-low-energy.md
  • src/todo/radio-hacking/README.md
  • src/todo/radio-hacking/fissure-the-rf-framework.md
  • src/generic-methodologies-and-resources/pentesting-wifi/README.md
  • src/SUMMARY.md
• Determined the best location: The existing BLE page under “Radio Hacking” already ...
