Redbot Security IoT Device Testing is a manual penetration testing service that assesses both hardware and software components of connected IoT devices. The service covers the full device lifecycle, from initial deployment through decommissioning, using a structured methodology that includes information gathering, threat modeling, vulnerability identification, exploitation, and detailed reporting with remediation guidance. Testing areas include: - Embedded Firmware Security: Analysis of firmware binaries for hardcoded credentials, insecure update mechanisms, and buffer overflows. - Hardware Interface Testing: Assessment of physical ports and interfaces such as UART, JTAG, and SPI to prevent unauthorized access or tampering. - IoT Network Communication: Evaluation of protocols including MQTT, CoAP, HTTP(S), and proprietary implementations for weak encryption, improper authentication, and data leakage. - Mobile & Cloud App Integration: Testing of mobile applications and backend cloud APIs for insecure API calls, authentication issues, and weak authorization. - Bluetooth & RF Protocol Testing: Analysis of Bluetooth Classic, BLE, Zigbee, and other RF protocols for insecure pairing, sniffing risks, and unauthorized control. - OTA Update Security: Validation that over-the-air firmware update processes are encrypted, signed, and properly verified. - Device Lifecycle Assessment: Review of secure boot, data wiping, and end-of-life protections. The service is applicable across industries including healthcare, automotive, smart home, manufacturing, retail, utilities, agriculture, and logistics.
