Edge AIoT Pentesting

Traditional network pentesting changes paradigm when applied to edge devices executing AI models.

The Attack Surface

• Hardware Layer: JTAG/UART interfaces exposed on the PCB.
• Network Layer: BLE, Zigbee, LoRaWAN interception.
• Application Layer: Edge node API endpoints, often relying on weak authentication.
• Model Layer: Adversarial ML attacks to trick the edge AI.

Physical Exploitation

Using tools like Bus Pirate or a Logic Analyzer allows dumping firmware directly from the EEPROM/Flash. Once dumped, binwalk is your best friend.

binwalk -e firmware_dump.bin

Mitigation

Always implement secure boot and disable debug interfaces before final production shipment.
