TOOL 1: SHANNON — AUTONOMOUS WEB PENTESTER

Source: github.com/KeygraphHQ/shannon Score: 96.15% on XBOW source-aware benchmark (100/104 exploits) Model: Claude Agent SDK (Anthropic) Cost: ~$50/run | ~1-1.5 hours

What Shannon Finds

✅ IDOR — changes IDs across accounts, tests all API routes
✅ SQLi — error-based and time-based blind
✅ Command injection — OS separators in all inputs
✅ XSS — reflected + stored (confirmed in real browser)
✅ SSRF — webhook/fetch URL inputs, OOB callbacks
✅ JWT attacks — alg:none, RS256→HS256 confusion, weak keys
✅ Auth bypass — session fixation, forgot-password flaws
✅ Privilege escalation — viewer→admin, cross-tenant
✅ OAuth misconfigs — state parameter, redirect_uri

❌ Race conditions (sequential, not concurrent)
❌ Business logic (needs domain expertise)
❌ Smart contract bugs — use files 01-07 for these
❌ Novel techniques not in prompt templates

Setup

git clone https://github.com/KeygraphHQ/shannon
cd shannon && npm install
cp .env.example .env  # Add: ANTHROPIC_API_KEY=sk-ant-...
npm run build

# Direct mode (simple):
node dist/index.js --config configs/my-target.yaml

# Docker (includes nmap, subfinder, whatweb):
docker run --env-file .env \
  -v ./configs:/app/configs \
  keygraph/shannon:latest \
  --config configs/my-target.yaml

Config Template

# configs/target.yaml
target:
  name: "DeFi App Frontend"
  url: "https://app.DEFI.com"
  source_path: "/path/to/frontend/clone"  # white-box = much better
  additional_context: |
    DeFi app. Users connect MetaMask wallets.
    Focus on: IDOR in /api/portfolio?address=0x...,
    GraphQL introspection, JWT handling, SSRF via webhooks.
    DO NOT interact with smart contracts.

authentication:
  login_type: form  # form | sso | api | basic
  login_url: "https://app.DEFI.com/login"
  credentials:
    username: "attacker@test.com"
    password: "testpassword"
  login_flow:
    - "Fill in username field with $username"
    - "Fill in password field with $password"
    - "Click the login button"
  success_condition:
    type: url
    value: "/dashboard"

test_accounts:
  - username: "attacker@test.com"
    password: "testpassword"
    role: "viewer"
  - username: "victim@test.com"
    password: "victimpassword"
    role: "admin"

scope:
  include: ["https://app.DEFI.com/*"]
  exclude: ["https://app.DEFI.com/admin/destroy-all"]

The Shannon Workflow

YOUR PLAN:
1. Setup config + 2 test accounts (15 min)
2. Run Shannon (90 min) → do MANUAL business logic testing while it runs
3. Review Shannon findings (30 min) → verify each PoC manually
4. Manual hunting for what Shannon misses: race conditions, business logic, contract layer (60 min)
5. Write reports adapting Shannon's PoC to Immunefi/H1 format (30 min)

Shannon + manual = 4 hours → coverage that takes 2 days manually.

WARNINGS:

NEVER run on production without explicit written authorization
Check program rules: many prohibit automated scanning → instant rejection + ban
Only worth it for targets with max bounty ≥ $5K (costs ~$50)
Always verify findings manually before submitting — LLMs can hallucinate

TOOL 2: LUAN1AO — DUAL-GRAPH AUTONOMOUS PENTESTER

Source: github.com/SanMuzZzZz/LuaN1aoAgent Score: 90.4% on XBOW Benchmark (beats commercial XBOW at 85%) Architecture: Causal Graph + Plan-on-Graph (PoG) | P-E-R (Planner-Executor-Reflector) Cost: $0.09 median per exploit

What Makes LuaN1ao Different

Causal Graph: Every action requires evidence → no hallucinated attacks
Plan-on-Graph: DAG that rewrites itself mid-test → parallel independent paths
Reflector: L1-L4 failure attribution → learns from failures mid-run

Evidence Chain Example

Port scan → 3306/tcp open
  → Hypothesis: MySQL running (confidence 0.8)
  → Validated: banner confirms MySQL 5.7
  → Vulnerability: empty root password
  → Exploit: mysql -h target -u root -p

Setup

git clone https://github.com/SanMuzZzZz/LuaN1aoAgent && cd LuaN1aoAgent
python3 -m venv venv && source venv/bin/activate
pip install -r requirements.txt
cp .env.example .env
# Edit .env: set LLM_API_KEY + LLM_API_BASE_URL

# Build RAG knowledge base (one-time, ~5 min):
mkdir -p knowledge_base
git clone https://github.com/swisskyrepo/PayloadsAllTheThings knowledge_base/PayloadsAllTheThings
cd rag && python -m rag_kdprepare && cd ..

# Run:

For Web3 / DeFi Targets

python agent.py \
  --goal "Audit Ern protocol smart contracts for:
    1. Missing access control on distributeRewards() and harvest()
    2. Accounting desync between totalDeposited and aToken balance
    3. Any role never granted (permanent lock bugs)
    4. Reentrancy in harvest→distributeRewards sequence
  Target: github.com/[ern-repo]" \
  --task-name "ern_audit"

# HITL injection during run:
# "Check if harvest() can be called before any deposit — divide by zero?"

TOOL 3: CAI FRAMEWORK — OFFENSIVE SECURITY AGENT

Source: github.com/aliasrobotics/cai Score: Top-1 in HTB "Human vs AI" CTF | 3,600× faster than humans in CTF benchmarks Used at: HackerOne, Mercado Libre, Ecoforest, MiR Industrial

Bug Bounty Workflow

# Step 1: Recon
CAI_AGENT_TYPE=bug_bounter CAI_DEBUG=1 cai
# "Target: target.com — enumerate all endpoints, check Shodan, find exposed services"

# Step 2: Hunt specific class
# "Focus on /api/v2/ endpoints. Look for IDOR in user ID params.
#  Test authenticated vs unauthenticated. Document each finding."

# Step 3: Validate before submitting
CAI_AGENT_TYPE=retester cai
# "Validate this finding: [paste finding]. Confirm exploitable."

# Step 4: Generate report
CAI_AGENT_TYPE=reporter CAI_REPORT=pentesting cai
# "Generate bug bounty report for: [paste validated findings]"

For Smart Contract Investigation

# Tell CAI to use cast/foundry:
"Use cast and foundry to analyze this contract:
 0x9f76037494092aceac5b23e21c20b1970a866ef5

 Check:
 1. What roles exist? cast call addr 'getRoleMember(bytes32,uint256)' ROLE_HASH 0
 2. Who has DISTRIBUTOR_ROLE? cast logs with RoleGranted topic
 3. Can distributeRewards() be called without DISTRIBUTOR_ROLE?
 4. Any MEV opportunity in harvest→distribute flow?"

Key Agents

Agent	Use For
`bug_bounter`	General recon + vulnerability discovery
`retester`	Validate findings, eliminate false positives
`web_pentester`	HTTP analysis, JS surface extraction, GraphQL
`red_teamer`	Offensive ops
`reporter`	Auto-generate CTF/pentesting/NIS2 reports
`bb_triage`	Bug bounty discover → validate → deduplicate → report

Burp Suite + MCP:

CAI>/mcp load http://localhost:9876/sse burp
CAI>/mcp add burp bug_bounter
# Now has: send_http_request, proxy history, intruder, repeater, +16 more

TOOL 4: SMARTGUARD — MULTI-AGENT SOLIDITY AUDITOR

Source: github.com/advaitbd/smartguard Pipeline: Slither → RAG → 5 agents → Foundry PoC → auto-run → self-fix loop

What It Does

AnalysisAgent: Runs Slither, returns JSON of potential vulns
RAG Enhancement: Retrieves similar findings from DeFiHackLabs
ValidationAgent: Filters false positives (checks context, access control)
SkepticAgent: Kills findings that require impossible preconditions
PlannerAgent: Creates exploit strategy
ExploitRunnerAgent: Writes + runs Foundry PoC, self-corrects failures

Setup

git clone https://github.com/advaitbd/smartguard && cd smartguard
pip install -r requirements.txt
cp .env.example .env
# Set OPENAI_API_KEY or ANTHROPIC_API_KEY

Usage

# Audit a file
python main.py --contract src/Vault.sol

# Audit a directory
python main.py --contract src/

# Audit deployed contract (fetches from Etherscan)
python main.py --address 0x9f76... --network mainnet

# Output: console (default) or JSON
python main.py --contract src/Vault.sol --output json > findings.json

When to Use SmartGuard

First-pass scan before manual review (catches 60-80% of standard bugs)
Generate PoC scaffolding for bugs you found manually
Validate whether a finding is exploitable before writing full PoC
When you have many contracts to triage (batch scan)

TOOL 5: HUNTING AI-GENERATED CONTRACTS

Source: SolAgent paper (arxiv.org/abs/2601.23009) — AI writes 64% pass@1 vs 25% vanilla Solidity

Why AI-Written Code Is Vulnerable

AI code generators (SolAgent, Copilot, Cursor) pass basic tests but consistently miss:

Cross-function reentrancy — CEI in function A, shared state with function B
Off-by-one at boundaries — tests cover normal range, not boundary+1
Missing state on error path — happy path updates state, revert path doesn't
Sibling function access control — one function has guard, sibling doesn't
Constructor role grants missing — role defined but never assigned

Signatures of AI-Generated Code

# AI code is longer and more complex than human code (1.45× lines, 1.56× cyclomatic complexity)
# Look for these patterns:
grep -rn "// AI generated\|// Generated by\|// Copilot" src/ --include="*.sol"

# AI code: comprehensive NatSpec but missing edge cases
grep -rn "@notice\|@param\|@return" src/ --include="*.sol" | wc -l
# High NatSpec count but low test coverage = likely AI-generated

# AI code: defensive redundancy (lots of require statements)
grep -rn "require(" src/ --include="*.sol" | wc -l

# AI code: modifier + CEI pattern used correctly, but misses CROSS-FUNCTION case
grep -rn "nonReentrant" src/ --include="*.sol"
grep -rn "modifier only\|onlyRole" src/ --include="*.sol"
# Then check: do sibling functions that share state also have nonReentrant?

Hunt Strategy for AI-Written Contracts

# Step 1: Find all state variables that two+ functions write
grep -rn "^\s*\(uint\|int\|bool\|address\|mapping\|bytes\)\b" src/ --include="*.sol"
# For each: which
