Bluetooth/BLE Penetration Testing Toolkit for Automotive IVI Systems

Python 3.10+ License GPL-3.0 Version 2.6.3 101 Modules 37 CVEs Linux

Documentation · CLI Reference · CVE Matrix · Changelog


Blue-Tap is a Bluetooth Classic and BLE security assessment framework designed to find both known and unknown vulnerabilities in Bluetooth stacks. It targets automotive IVI systems, mobile devices, IoT endpoints, and embedded firmware — anything with a Bluetooth radio. 101 modules across 6 families cover the full pentest lifecycle from device discovery through 0-day hunting via protocol-aware fuzzing. A DarkFirmware capability on RTL8761B controllers extends testing below the HCI boundary into the Link Manager and Link Controller layers, reaching the 40-45% of the Bluetooth attack surface that host-only tools cannot see.

Features

Discovery & Reconnaissance — Classic and BLE device scanning, SDP/GATT enumeration, L2CAP/RFCOMM channel probing, device fingerprinting, HCI capture, BLE/LMP sniffing, capability detection, and cross-probe correlation. Guide

Vulnerability Assessment — 25 CVE detections (behavioral + compliance) and 11 non-CVE posture checks covering L2CAP, BNEP, SDP, AVRCP, GATT, HID, SMP, and pairing protocols. CVE Matrix

Exploitation — KNOB (CVE-2019-9506), BIAS (CVE-2020-10135), BLUFFS (CVE-2023-24023), CTKD (CVE-2020-15802), encryption downgrade, SSP downgrade, connection hijack, and PIN brute-force. Guide

Denial of Service — 9 CVE-backed crash probes and 21 protocol stress tests across L2CAP, SDP, RFCOMM, BNEP, HFP, OBEX, LMP, and pairing with automatic recovery monitoring. DoS Matrix

Post-Exploitation — Phonebook extraction (PBAP), message access (MAP), call audio (HFP), audio streaming (A2DP), media control (AVRCP), file push (OPP), Bluesnarfer (OBEX), and AT command probing. Guide

Protocol Fuzzing — 16-protocol mutation fuzzer with coverage-guided, state-machine, targeted, and random-walk strategies. Crash database, payload minimization, CVE reproduction, and live Rich dashboard. 6,685+ seeds. Guide

DarkFirmware (Below-HCI) — RTL8761B firmware patching for LMP injection, link-layer monitoring, and controller memory R/W. Reaches the 40-45% of Bluetooth CVEs invisible to host-only tools. Hardware Setup

Reporting & Sessions — Professional HTML and JSON reports with 11 per-module adapters. Persistent sessions for multi-phase assessments. Guide

Installation

Prerequisites

  • Linux (Kali recommended)
  • Python 3.10+
  • BlueZ 5.50+ (bluetoothctl, hcitool, btmon)
  • An RTL8761B-based USB dongle (e.g., TP-Link UB500) — Blue-Tap currently gates all live operations behind RTL8761B detection. Stock firmware is fine; DarkFirmware unlocks below-HCI features.
  • Root privileges for Bluetooth operations

Inspection commands that work without root and without an adapter: --help, --version, doctor, demo, session list/show, report (including report <dir>), fuzz crashes list/show/export, fuzz corpus list/minimize, fuzz minimize, run-playbook --list, search, info, show-options, plugins. Anything that touches the Bluetooth stack — discover, recon, vulnscan, exploit, dos, extract, fuzz campaign, auto, fleet, adapter, spoof, run-playbook (without --list) — needs sudo and an RTL8761B dongle.

Via PyPI

pip install blue-tap

From Source

git clone https://github.com/Indspl0it/blue-tap.git
cd blue-tap
pip install -e .

Verify Installation

blue-tap --version          # prints 'blue-tap, version 2.6.3'
blue-tap doctor             # check prerequisites — no root, no hardware needed
blue-tap session list       # list past sessions — no root, no hardware needed
blue-tap demo               # full pipeline against simulated data — no hardware needed
sudo blue-tap adapter list  # enumerate live HCI adapters (needs root + RTL8761B)

See the full Installation Guide for detailed setup, including DarkFirmware flashing.

Usage

Blue-Tap follows a phase-verb workflow that mirrors a real-world Bluetooth pentest:

discover  →  recon  →  vulnscan  →  exploit  →  dos  →  extract  →  fuzz  →  report

Quick Start

# 1. Find nearby Bluetooth devices
sudo blue-tap discover classic -d 20

# 2. Deep recon on a target
sudo blue-tap recon 4C:4F:EE:17:3A:89 sdp
sudo blue-tap recon 4C:4F:EE:17:3A:89 fingerprint

# 3. Scan for vulnerabilities (25 CVE + 11 posture checks)
sudo blue-tap vulnscan 4C:4F:EE:17:3A:89

# 4. Exploit a confirmed vulnerability
sudo blue-tap exploit 4C:4F:EE:17:3A:89 knob --yes

# 5. Extract data post-exploitation
sudo blue-tap extract 4C:4F:EE:17:3A:89 contacts --all

# 6. Generate HTML report
blue-tap report --format html --output report.html

Automation

# Full automated assessment against a single target
sudo blue-tap auto 4C:4F:EE:17:3A:89 --yes

# Fleet scan — discover and assess all IVI devices in range
sudo blue-tap fleet --duration 20 --class ivi

# Run a bundled playbook (see `blue-tap run-playbook --list` for all)
sudo blue-tap run-playbook --playbook ivi-attack 4C:4F:EE:17:3A:89

Fuzzing

# Multi-protocol fuzzing campaign (needs hardware)
sudo blue-tap fuzz campaign 4C:4F:EE:17:3A:89 -p sdp -p rfcomm --duration 2h

# Crash analysis (no root, no hardware needed — pure on-disk crash database)
blue-tap fuzz crashes list --protocol sdp --severity HIGH
blue-tap fuzz crashes show CRASH_ID
blue-tap fuzz crashes export -o crashes.json

# Get help for any fuzz subcommand
blue-tap fuzz crashes --help
blue-tap fuzz campaign --help
