Clawdbot Scanner

A comprehensive TypeScript-based scanner for probing, fingerprinting, and analyzing Clawdbot Gateway instances. Built with a multi-agent architecture to validate honeypots by comparing them against real Clawdbot instances.

Overview

This scanner was designed to discover, probe, and analyze Clawdbot Gateway services across the internet to detect honeypots with high accuracy. It uses protocol-level fingerprinting, behavioral analysis, and comparative validation to identify deviations from legitimate Clawdbot instances.

Current Status: ✅ Fully functional with 62.5% method coverage and 74% honeypot detection accuracy + enhanced security, reliability, and resilience features

Architecture

Built using a 4-agent parallel development approach:

1. Protocol Agent - WebSocket client, handshake, 32 methods
2. Discovery Agent - Shodan API + mDNS discovery
3. Analysis Agent - Fingerprinting + honeypot detection
4. Report Agent - Database, dashboards, multi-format exports

See ARCHITECTURE.md for detailed architecture documentation.

• state - State updates from server

Fingerprinting Features

The analysis engine extracts 8 categories of features:

1. Protocol Features - Method support, error patterns
2. Behavioral Features - Response times, event frequencies
3. State Features - State versioning, snapshot behavior
4. Event Features - Tick intervals, event types
5. Error Features - Error codes, error messages
6. Timing Features - Connection latency, response patterns

• ❌ Missing type field in request frames
• ❌ Wrong handshake format

After Protocol Fix

• ✅ 20/32 methods working (62.5% success)

Programmatic Usage

import { ClawdbotProtocolClient } from './protocol/client';
import { Fingerprinter } from './analysis/fingerprint';
import { HoneypotComparator } from './analysis/comparator';

// Create client
const client = new ClawdbotProtocolClient({
  debug: true,
  connectionTimeout: 10000,
  requestTimeout: 5000
});

// Connect and authenticate
await client.connect('178.62.226.116', 18789);
const handshake = await client.connectHandshake();

// Probe all methods
const results = await client.probeAllMethods();

// Listen for events
client.on('tick', (event) => {
  console.log('Tick:', event);
});

// Analyze for honeypot indicators
const fingerprinter = new Fingerprinter();
const fingerprint = fingerprinter.analyze(results);

const comparator = new HoneypotComparator();
const analysis = comparator.compare(fingerprint, knownFingerprints);

console.log(`Confidence: ${analysis.confidence}%`);
console.log(`Assessment: ${analysis.assessment}`);

// Cleanup
client.disconnect();
