The Finding That Matters

👻 GHOST AGENT DETECTED
   Workload:   trading-bot (Deployment/default)
   Connected:  api.openai.com — LIVE
   SaaS:       openai — confirmed active connection
   Source code: None found in scanned repositories
   Owner:      Unknown — no deployment record, no code review

👻 GHOST AGENT DETECTED
   Workload:   shadow-agent (Pod/kube-system)
   Connected:  api.anthropic.com — LIVE
   SaaS:       anthropic — confirmed  |  gcp — active socket
   Blast radius: HIGH (cloud provider access confirmed)
   Source code: None found in scanned repositories
   Owner:      Unknown — no deployment record, no code review

An AI system is making real API calls — consuming tokens, potentially accessing sensitive data — and your engineering team has no record of it. No code, no deployment, no owner. AgentDiscover Scanner finds these in under 60 seconds.

That's the problem. Your engineering team thinks they know what AI systems are running. They don't.

---

What Makes This Different

Most security tools tell you what's in your code. AgentDiscover Scanner tells you what's actually running — and crucially, what's running that has no business being there.

The GHOST classification is unique: an AI system observed making real API calls with zero corresponding source code. No other static analysis tool can find this. No SIEM will alert on it. It only appears when you watch the runtime and cross-reference it against your codebase simultaneously.

As of v2.3.0, every detected agent also carries a SaaS blast radius — a live-observed map of which services it's actively connected to, derived from network traffic not just configuration files.

crewai-agent (CONFIRMED)
  saas_connections:
    anthropic: confirmed  ← active_connection observed
    github:    medium     ← open socket
  risk_flags: [cloud_credentials_present]
  blast_radius: 70/100

Agent Classifications

Classification	What It Means	Risk
👻 GHOST	Runtime AI activity — no source code found	Critical
✅ CONFIRMED	Detected in code AND observed running	High
⚠️ UNKNOWN	Found in code, not yet observed at runtime	Medium
🖥️ SHADOW AI	Known app using AI without governance	Medium
☠️ ZOMBIE	Was active, no longer observed	Low

GHOST agents are the most dangerous finding. An AI system is making real API calls — consuming tokens, potentially accessing sensitivneering team has no record of it. No code, no deployment, no owner.

Quick Start

pip install agent-discover-scanner
agent-discover-scanner scan-all /path/to/your/code --duration 30

For Kubernetes environments:

curl -fsSL https://raw.githubusercontent.com/Defend-AI-Tech-Inc/agent-discover-scanner/main/install.sh | sudo bash
agent-discover-scanner scan-all /path/to/code --daemon --output /var/log/defendai

To upload results to the DefendAI platform:

agent-discover-scanner scan-all /path/to/code \
  --platform \
  --api-key YOUR_API_KEY

How It Works

AgentDiscover Scanner runs four detection layers simultaneously and correlates them into a single agent inventory. Each layer sees something the others can't.

Layer 1 — Source Code Analysis

Static analysis of Python and JavaScript/TypeScript. Detects LangChain, LangGraph, CrewAI, AutoGen, direct OpenAI/Anthropic/Gemini API usage, and any HTTP client targeting LLM endpoints. Handles import aliasing and iirect usage patterns. Generates SARIF output for CI/CD integration.

Layer 2 — Live Network Monitoring

Passive observation of outbound connections to AI providers — OpenAI, Anthropic, Google Gemini, Mistral, Cohere, Azure OpenAI, AWS Bedrock, and vector stores. No packet capture. Identifies which process is making each connection, enabling per-agent SaaS attribution.

Layer 3 — Kubernetes Runtime (eBPF)

Kernel-level visibility into pod behavior via Tetragon. Identifies which workloads are actively making AI calls — including workloads with no corresponding source code. Works with any CNI. Falls back to Kubernetes API discovery if Tetragon is unavailable.

Layer 4 — Endpoint Discovery

Scans developer machines, CI/CD runners, and workstations via osquery. Finds installed AI packages, desktop AI applications (ChatGPT Desktop, Claude Desktop, Cursor, GitHub Copilot), active connections, browser-based AI usage, and VSCode extensions.

SaaS Blast Radius Detection (v2.3.0+)

After correlation, each agent receives a saas_connections profile built from all four layers:

{
  "detected":  ["anthropic", "gcp", "github"],
  "confirmed": ["anthropic"],
  "evidence": {
    "anthropic": ["active_connection", "open_socket"],
    "gcp":       ["open_socket"],
    "github":    ["vscode_extension_detected"]
  },
  "confidence": {
    "anthropic": "confirmed",
    "gcp":       "medium",
    "github":    "medium"
  },
  "has_cloud_provider": true,
  "has_llm_provider":   true
}

confirmed means the connection was live-observed during the scan — not inferred from config files. This is the difference between "this agent is configured to use Anthropic" and "this agent is calling Anthropic right now."

 Classification  | Count | Description
-----------------|-------|--------------------------------------------------
 CONFIRMED       |   2   | Active — detected in code and observed at runtime
 UNKNOWN         |   3   | Code found — not yet observed at runtime
 SHADOW AI       |   0   | Known app using AI — review for governance
 ZOMBIE          |   0   | Inactive — code exists but no recent activity
 GHOST           |   1   | ⚠ Critical — runtime activity with no source code

Risk Breakdown:
  ● Critical: 1

Daemon Mode

Run continuously as a background service, updating the agent inventory every 30 seconds:

agent-discover-scanner scan-all /path/to/code \
  --daemon \
  --output /var/log/defendai \
  --platform \
  --platform-interval 5    # upload to platform every ~2.5 minutes

With --platform, the daemon syncs to the DefendAI platform every N correlation cycles (default: every 5 cycles ≈ 2.5 minutes) and always uploads a final snapshot on shutdown.

Install as a systemd service:

sudo bash deployment/systemd/install-service.sh /path/to/code
systemctl status defendai-scanner

---

Customizing Known Applications

By default the scanner classifies common desktop applications (browsers, Office 365, Cursor, Slack, Claude Desktop, etc.) as Shadow AI rather than GHOST when they make AI API calls. To add your own internal tools:

mkdir -p ~/.defendai
echo "my-internal-ai-tool" >> ~/.defendai/known_apps.txt
echo "company-llm-client" >> ~/.defendai/known_apps.txt

See docs/known-apps-example.txt for the full format.

When connected to the DefendAI platform (--platform flag), the tenant-managed list is downloaded automatically on startup and merged with your local overrides.

---

DefendAI Platform Integration

The scanner is the discovery layer. The platform is where discovered agents become governed agents.

agent-discover-scanner scan-all /path/to/code \
  --platform \
  --api-key YOUR_KEY \
  --duration 30

When connected to the platform, each scan triggers the correlation engine which builds a living identity map across every machine, every environment, and every scan:

• Agent Identity Resolution — the same CrewAI agent on a laptop, in staging k8s, and in prod k8s is recognized as one agent at different lifecycle stages
• Behavioral Drift Detection — agent added has_code_execution=true since last week? That's a signal. Platform tracks it.
• Cross-Machine Intelligence âagent seen on 3 machines and crossed from dev into prod? Automatic risk escalation
• SaaS Blast Radius — platform aggregates confirmed SaaS connections across all scans and computes blast radius score

After aew scans, the DefendAI platform report shows:
