🚀 Bot Analyzer Enhancements (v3.0)

Attack Vector Detection

OLD: Only detected SQL injection and generic scanners

NEW: Detects 6 attack types:

💉 SQL Injection       - UNION, SELECT, hex encoding
🌐 XSS Attacks         - JavaScript injection, event handlers
📁 Path Traversal      - Directory traversal, LFI
📤 RCE/Shell Upload    - PHP shells, backdoors
🔍 Info Disclosure     - .git, .env, config files
🔓 Login Bruteforce    - wp-login, xmlrpc attacks

Threat Scoring System

NEW Feature: Each IP gets 0-100 risk score

Example Output:

[1] 143.244.57.123 - RISK: 98/100 🔴 CRITICAL
    648 requests - Action: BLOCK IMMEDIATELY + INVESTIGATE
    Attack vectors: SQL-Injection RCE/Upload Login-Bruteforce DDoS-Pattern

Score Components:

  • Request volume: up to 10 points
  • Attack patterns: up to 70 points
  • Behavioral signals: up to 20 points

Time-Series Analysis

NEW: Hourly traffic visualization

Bot Traffic Timeline (hourly):
  14:00-15:00: ████████░░ 8,240 bot requests
  15:00-16:00: ███░░░░░░░ 3,120 bot requests
  16:00-17:00: ██████████ 12,450 bot requests ⚠️ SPIKE

Response Code Intelligence

NEW: Shows what bots are finding

200 (Success):     18,432 (62%) ✓ Bots are getting data
404 (Not Found):    7,891 (27%) ⚠️ Scanning for vulnerabilities
403 (Forbidden):    2,103 (7%)  ✓ Blocked by existing rules
500 (Server Error):    12 (0%)  🚨 Check if exploit triggered

False Positive Detection

NEW: Auto-identifies legitimate services

⚠️ Whitelist Recommendations:
  65.181.111.155 - 11,515 requests - Identified as: Pingdom Monitoring
    → Action: VERIFY OWNERSHIP then whitelist

Detects:

  • Pingdom, UptimeRobot, StatusCake
  • WordPress cache preload (WP Rocket, Hummingbird)
  • Backup services (Jetpack, VaultPress)

Server IP Detection

NEW: Auto-detects and excludes server's own IPs

5 Detection Methods:

  1. hostname -I (network interfaces)
  2. ip addr show (Linux IP command)
  3. ifconfig (legacy fallback)
  4. External services (public IP)
  5. cPanel mainip file

Output:

✓ Detected 2 server IP(s) - excluded from threat analysis

🖥️  Server IPs Detected:
  • 127.0.0.1
  • 67.227.199.95

Bandwidth Cost Estimation

NEW: Shows financial impact

💰 Bandwidth Impact:
   Total bot bandwidth: 847 MB (0.85 GB) - 14.2% of total
   Estimated cost: $0.08 (at $0.09/GB CDN pricing)

Prioritized Blocklists

OLD: Random order, no context

NEW: Sorted by threat score with annotations

# IPs sorted by risk score (highest first)
Deny from 91.92.243.107  # Risk score: 98/100
Deny from 34.192.124.246  # Risk score: 85/100
Deny from 4.245.190.15    # Risk score: 72/100

Performance Optimization

MASSIVE Speed Improvement:

Dataset Old Method New Method Speedup
1,000 IPs / 50K entries ~2 minutes ~2 seconds 60x
10,000 IPs / 250K entries ~10 minutes ~10 seconds 60x
25,000 IPs / 500K entries ~30 minutes ~30 seconds 60x
50,000 IPs / 1M entries ~2 hours ~60 seconds 120x

How?

  • Eliminated 275,000 grep operations
  • Pre-count requests (single pass)
  • Hash table lookups (O(1) vs O(n))
  • Smart caching
