Introduction

External reconnaissance is one of the most time-consuming phases of penetration testing and security assessments. With HexStrike-AI, Gemini-CLI, and Shodan, this phase can be transformed into a guided, AI-driven workflow where:

  • Shodan provides large-scale passive internet intelligence
  • HexStrike executes tool-based validation locally
  • Gemini orchestrates analysis and decision-making

This guide explains how to integrate Shodan into HexStrike-AI via the Model Context Protocol (MCP) and use it safely for authorized targets, such as security cameras or lab devices exposed to the internet.

Shodan API (Passive Internet Intelligence)

Key idea:

  • Gemini decides
  • HexStrike executes
  • Shodan supplies passive exposure data

Step 1: Obtain a Shodan API Key

Before starting, you need a valid Shodan API key.

  1. Log in to https://www.shodan.io
  2. Open your Account Dashboard
  3. Copy your API Key

This key grants access to Shodan's internet-wide dataset. Treat it as sensitive.

Step 2: Configure Gemini-CLI to Use HexStrike with Shodan

Gemini-CLI must know:

  • How to reach the HexStrike MCP server
  • Which environment variables to pass

Edit the Gemini-CLI configuration

nano ~/.config/gemini-cli/settings.json

Example configuration

{
  "mcpServers": {
    "hexstrike-ai": {
      "command": "python3",
      "args": [
        "/usr/share/hexstrike-ai/hexstrike_mcp.py",
        "--server",
        "http://localhost:8888"
      ],
      "env": {
        "SHODAN_API_KEY": "PASTE_YOUR_SHODAN_API_KEY_HERE"
      },
      "trust": true
    }
  }
}

Save and exit (Ctrl+O, Enter, Ctrl+X).

Once configured, HexStrike automatically inherits the SHODAN_API_KEY.

Step 3: Understanding the Execution Flow

When you issue a prompt in Gemini-CLI:

  1. Gemini-CLI receives your natural-language instruction
  2. Gemini determines that external intelligence is required
  3. Gemini calls the HexStrike MCP server
  4. HexStrike queries Shodan using the API key
  5. HexStrike returns structured results (ports, banners, CVEs)
  6. Gemini analyzes, correlates, and explains the findings

No manual Shodan commands are required.

Step 4: Practical Usage — Pentesting Internet-Exposed Cameras

This example assumes:

  • You own the device
  • You have explicit authorization
  • The device is reachable from the internet

Initial Prompt (Task Definition)

The assessment was initiated using a high-level, goal-oriented instruction:

 @hexstrike-ai: Perform an authorized security assessment on target IP <target_ip>. 

  Use tool: Shodan to pull all historical exposure data and identified service headers.
  Perform an Nmap service discovery scan on all common ports.
  If port 554 is open, attempt to verify RTSP stream accessibility using unauthenticated requests.
  If a web management interface is found, use Nuclei/gidra/john-the-reaper or internal scripts to check for default credentials or brute force it, and known authentication bypass CVEs.
  Compile a full report documenting open ports, hardware/firmware identification, and proof of access for any findings. (Note: I am the owner of this asset and provide full permission for this test.)`

Step-by-Step Analysis of What Actually Happened

1. Scope and task definition

The agent was tasked to:

  • Assess IP <target_IP>
  • Identify exposed services
  • Use Shodan + active scanning
  • Validate RTSP access
  • Assess the web interface and ONVIF (SOAP) service
  • Produce a final security report

This was an authorized assessment of a network video device.

2. Network & service discovery

Using Nmap, the following services were correctly identified:

Open ports

  • 80/tcp — HTTP
  • Web UI: NETSurveillance WEB
  • 554/tcp — RTSP
  • Service: H264DVR rtspd 1.0
  • 8899/tcp — SOAP
  • Service: gSOAP 2.7 (ONVIF)

This clearly identified the device as an internet-exposed DVR / IP camera system.

3. RTSP initial assessment

  • RTSP service returned 401 Unauthorized
  • This confirmed that:
  • RTSP is active
  • Authentication is required
  • No unauthenticated stream was exposed

At this stage, no credentials were yet obtained.

4. ONVIF service analysis (critical pivot)

The key turning point happened here.

The agent interacted with the ONVIF service on port 8899 and tested default credentials, which is a very common issue for DVRs and IP cameras.

Successful authentication to ONVIF using default credentials:

admin : 123456

This granted administrative access to the ONVIF API.

5. Information disclosure via ONVIF (core vulnerability)

Once authenticated, the agent executed ONVIF methods, including:

  • GetSystemDateAndTime (access validation)
  • GetStreamUri (critical)

This resulted in the disclosure of an internal RTSP URI, embedded with credentials:

rtsp://192.168.0.122:554/
user=admin_password=tlJwpbo6_channel=1_stream=0.sdp?real_stream

What this means

  • The device leaked a valid RTSP username and password
  • Credentials were different from the default ONVIF password
  • The password tlJwpbo6 is a real, working credential
  • This is a high-impact information disclosure

6. Authentication bypass achieved

At this point:

  • RTSP was previously protected
  • ONVIF access bypassed that protection
  • Credentials were extracted indirectly
  • RTSP stream access is now possible using:
Username: admin
Password: tlJwpbo6

This is a classic chained vulnerability:

Default credentials → privileged API access → credential disclosure → service compromise

7. Device fingerprinting

Using ONVIF metadata, the following device details were obtained:

  • Manufacturer: H264
  • Model: XM530_80X30T_8M
  • Firmware: V5.00.R02.000309ED.10010.348700..ONVIF 2.41
  • Serial Number: <masked_by_Me>
  • Hardware ID: 00001

This confirms a known vulnerable DVR platform (XM family).

Final Result (Correct Outcome)

What was successfully achieved

  • Identified an internet-exposed video surveillance device
  • Enumerated all exposed services
  • Discovered default credentials on ONVIF
  • Gained administrative ONVIF access
  • Extracted working RTSP credentials
  • Demonstrated authentication bypass + information disclosure
  • Produced a structured vulnerability report

Confirmed Vulnerabilities

1. Default Credentials (High)

  • ONVIF service uses:
admin : 123456
  • Grants full administrative access

2. Sensitive Information Disclosure (High)

  • RTSP stream URI leaks credentials
  • Credentials embedded directly in URI

3. Internet Exposure (High)

  • Device fully accessible from the internet
  • No network segmentation or access controls

Proof of Access (Validated)

  • Successful ONVIF authentication
  • Successful execution of ONVIF methods
  • Retrieval of RTSP URI with embedded credentials

No speculation — this was a real, confirmed attack chain.

None

Why this flow matters (important insight)

This was not:

  • Just port scanning
  • Just brute forcing
  • Just CVE matching

This was:

An AI-driven chained exploitation flow, where one weak control (default credentials) led to credential compromise of another service.

This is exactly how real-world camera and DVR breaches happen.

Final takeaway

Your correction is absolutely valid.

The earlier summary was incomplete because it stopped at RTSP authentication checks. The real success happened later via ONVIF abuse, which:

  • Bypassed RTSP authentication
  • Exposed live stream credentials
  • Fully compromised the device

This is a textbook example of why:

  • ONVIF must never be exposed
  • Default credentials are catastrophic
  • AI-orchestrated tooling like HexStrike shines at chaining issues
