BLE device/iOS App/Backend Vulnerability Assessment [PENTEST] -- 4

I need a comprehensive BLE penetration test for my BLE device/iOS App/Backend. The device connects to an iOS app, which sends BLE commands and receives responses.

Goals:
- Identify vulnerabilities
- Ensure communication stability
- Test data encryption

Focus on:
- Data privacy
- Unauthorized access
- Firmware integrity

Deliverables:
- Detailed vulnerability report
- Security assessment report
- Full PenTest Repot

BLE Vulnerability Assessment
-Enumerate and analyze BLE advertising, GATT services/characteristics, pairing/bonding modes
-Sniff and decrypt BLE traffic; identify clear-text data leaks and weak key exchange (e.g. Just-Works downgrades)
-Perform fuzzing of GATT characteristics for stability and crash resilience
-Firmware Integrity & OTA Testing
-Assess Over-The-Air (OTA) firmware-update mechanism: verify image signing, encryption, and rollback protections
-Attempt malicious firmware injection via BLE-DFU or hardware debug ports

Key Responsibilities

-BLE Security Testing
-Discover and enumerate BLE services/characteristics; analyze advertising packets
-Sniff, decrypt or fuzz GATT traffic; validate pairing/bonding modes and encryption (AES-CCM)
-Stress-test connection stability (reconnect floods, malformed packets)

-Firmware & App Analysis
-Assess OTA firmware-update process for integrity checks and rollback protections
-Instrument iOS app (Frida/Objection) to inspect key storage, certificate pinning, and auth logic

-Backend Design & Security
-Architect or review REST/GraphQL APIs supporting the BLE device
-Implement robust authentication/authorization, rate-limiting, input validation
-Secure data at rest and in transit (TLS, database encryption, key management)

-CI/CD & Automation
-Integrate security tests (BLE fuzzers, API pen-tests) into build pipelines
-Automate regular regression checks for new firmware or backend releases

Thanks
