AI Agent Security Testing Framework — multi-phase scan campaigns with knowledge graph tracking

ZIRAN 🧘 — AI Agent Security Testing

Test AI agents for vulnerabilities using Romance Scan methodology and knowledge graphs.

ZIRAN systematically discovers security weaknesses in AI agents — not just LLMs, but agents with tools, memory, and multi-step reasoning.

🎯 What Makes ZIRAN Different

Unlike traditional LLM testing tools (PyRIT, Garak), ZIRAN is built for AI agents:

	ZIRAN	PyRIT	Garak	Snyk Evo
Tool Chain Analysis	✅	❌	❌	❌
Multi-phase campaigns	✅	Partial	❌	❌
Knowledge graph tracking	✅	❌	❌	❌
Agent-aware (tools + memory)	✅	❌	❌	Partial
Framework agnostic	✅	✅	✅	❌
Open source	✅	✅	✅	❌

Core Differentiators

• 🔗 Tool Chain Analysis — Automatically detects dangerous tool combinations (e.g. read_file → http_request = data exfiltration). No other tool does this.
• 🧪 Romance Scan Methodology — Multi-phase trust exploitation campaigns that build rapport before testing boundaries — like a real attacker.
• 🗺️ Knowledge Graph Tracking — Visual attack progression analysis with interactive graph visualization.
• 🔌 Framework Agnostic — Works with LangChain, CrewAI, Bedrock, MCP, and custom agents.

🔍 What ZIRAN Finds

Prompt-Level Vulnerabilities

• Prompt Injection — Direct and indirect instruction override
• System Prompt Extraction — Leaking system instructions
• Memory Poisoning — Persistent manipulation across turns
• Chain-of-Thought Manipulation — Hijacking reasoning steps

Tool-Level Vulnerabilities

• Tool Manipulation — Tricking agents into misusing tools
• Data Exfiltration Chains — read_file → http_request
• Privilege Escalation Paths — search_db → update_permissions
• SQL to RCE — sql_query → execute_code

Dangerous Tool Chains (Unique to ZIRAN)

ZIRAN automatically analyzes your agent's tool graph to find dangerous combinations:

⛓️  Dangerous Tool Chains:
┌──────────┬─────────────────────┬─────────────────────────────┬──────────────────────────────────────┐
│ Risk     │ Type                │ Tools                       │ Description                          │
├──────────┼─────────────────────┼─────────────────────────────┼──────────────────────────────────────┤
│ critical │ data_exfiltration   │ read_file → http_request    │ File contents sent to external server│
│ critical │ sql_to_rce          │ sql_query → execute_code    │ SQL results executed as code         │
│ high     │ pii_leakage         │ get_user_info → external_api│ User PII sent to third-party API     │
│ high     │ file_manipulation   │ read_file → write_file      │ Files read and arbitrarily modified  │
└──────────┴─────────────────────┴─────────────────────────────┴──────────────────────────────────────┘

🧪 Romance Scan Methodology

ZIRAN's multi-phase campaign mirrors real-world social engineering:

#	Phase	Goal
1	Reconnaissance	Discover capabilities, tools, and data sources
2	Trust Building	Establish conversational rapport with the agent
3	Capability Mapping	Deep understanding of tools, permissions, data access
4	Vulnerability Discovery	Identify attack paths and weaknesses
5	Exploitation Setup	Position for attack without triggering defenses
6	Execution	Execute the exploit chain
7	Persistence	Maintain access across sessions (opt-in)
8	Exfiltration	Extract sensitive data or capabilities (opt-in)

Each phase builds on knowledge from previous phases, tracked via a live knowledge graph.

📊 Reports

ZIRAN generates three report formats:

• Interactive HTML — Knowledge graph visualization with clickable nodes, attack path highlighting, and dangerous chain callouts
• Markdown — Clean summary with tables for CI/CD integration
• JSON — Machine-parseable for programmatic analysis

⚙️ How It Works

ZIRAN treats agent security testing as a stateful, multi-phase campaign — not a one-shot prompt check. Here's the pipeline:

Your Agent                    ZIRAN
─────────                    ────

                    └──────────────────────────┘

Step by step

1. Discover capabilities via the adapter layer. You provide a thin BaseAgentAdapter (≈4 methods). ZIRAN calls discover_capabilities() and sends reconnaissance prompts through invoke(). The adapter abstracts the framework — LangChain, CrewAI, MCP, or your own — so ZIRAN never talks to a specific SDK directly.

2. Build the knowledge graph. Every tool, data source, permission, and agent state becomes a node in a directed multigraph (nx.MultiDiGraph). Edges encode relationships: uses_tool, accesses_data, can_chain_to, enables. This graph accumulates state across all phases — later phases see everything earlier phases discovered.

3. Analyze tool chains. The ToolChainAnalyzer walks the graph looking for three kinds of dangerous composition:

Chain type	What it finds	Example
Direct	A has an edge to B, and (A, B) matches a known pattern	read_file → http_request → data exfiltration
Indirect	A reaches B through ≤3 intermediate nodes	read_file → transform → http_request
Cycle	A circular path that enables repeated exploitation	read_file → write_file → http_request → read_file

Pattern matching is substring-based so tool_read_file still matches the read_file pattern. Each chain gets a 0–1 risk score that factors in base severity, chain topology, and graph centrality of the involved nodes.

4. Execute attack campaigns. The AgentScanner orchestrates multi-phase attacks. It pulls YAML-defined attack vectors from the AttackLibrary, renders prompt templates with context from the knowledge graph, sends them through the adapter, and evaluates responses using pluggable detectors. The Romance Scan methodology means ZIRAN builds trust first (like a real attacker) before testing boundaries — earlier phases produce low-suspicion probes; later phases attempt actual exploitation.

5. Score and report. Results are aggregated into a CampaignResult: vulnerability counts, trust score trajectory, dangerous chain list, and per-phase breakdowns. Reports are emitted as interactive HTML (with graph visualization), Markdown (for CI/CD), and JSON (for programmatic consumption). Every finding includes the full attack path, evidence, and remediation guidance.

🔌 Writing a Custom Adapter

Test any AI agent by implementing the BaseAgentAdapter interface:

from ziran.domain.interfaces.adapter import BaseAgentAdapter, AgentResponse
from ziran.domain.entities.capability import AgentCapability

class MyAdapter(BaseAgentAdapter):
    async def invoke(self, message: str, **kwargs) -> AgentResponse:
        result = await my_agent.run(message)
        return AgentResponse(content=result.text)

    async def discover_capabilities(self) -> list[AgentCapability]:
        return [...]  # Return agent's tools/capabilities

    def get_state(self) -> AgentState: ...
    def reset_state(self) -> None: ...
