🔧 How It Works

Analysis Pipeline (5 Phases)

Phase 1: Client Detection (0-25%)
├─ Scans ARP table for connected devices
├─ Matches clients to WiFi networks
├─ Resolves hostnames
└─ Looks up manufacturers via OUI

Phase 2: Rogue AP Detection (25-40%)
├─ Detects evil twins (duplicate SSIDs)
├─ Flags suspicious SSID patterns
├─ Identifies weak encryption
└─ Checks for unauthorized APs

Phase 3: Channel Analysis (40-60%)
├─ Groups networks by channel
├─ Calculates utilization percentage
├─ Measures interference levels
└─ Identifies optimal channels

Phase 4: Vulnerability Scan (60-80%)
├─ Checks for open networks
├─ Detects WEP/WPA weaknesses
├─ Identifies default SSIDs
└─ Checks for KRACK vulnerability

Phase 5: Historical Update (80-100%)
├─ Updates network history records
├─ Tracks first/last seen timestamps
├─ Records channel observations
└─ Saves to persistent storage

🔍 Detection Algorithms

Evil Twin Detection

Group networks by SSID
If same SSID has multiple BSSIDs:
  → Flag as Evil Twin (HIGH severity)

Client Detection

Read ARP table → Get all local IPs + MACs
Match IP subnet to network
Lookup manufacturer from MAC OUI
Estimate signal strength

Channel Utilization

Utilization = (network_count × 15%) + (avg_signal_strength / 2)
Interference = network_count mapping:
  1 network   = None
  2 networks  = Low
  3-4 networks = Medium
  5-7 networks = High
  8+ networks = Severe

Security Scoring

Base Score = 100
Penalties:
  - Critical Alert: -20 points
  - High Alert: -10 points
  - Rogue AP: -15 points
  - Vulnerability: -5 points

Grade:
  90-100: A
  80-89:  B
  70-79:  C
  60-69:  D
  0-59:   F

🐛 Known Limitations

Current Implementation

Limitations:

  1. Client Detection: Based on ARP table (only shows local subnet clients)
  2. No Packet Capture: Doesn't sniff WiFi frames (requires monitor mode)
  3. No Deauth Detection: Can't detect active deauthentication attacks
  4. No GPS Tagging: Location tracking not implemented
  5. Single Subnet: Only analyzes 192.168.1.x subnet clients

Why These Limitations:

  • macOS doesn't expose raw WiFi packet capture to apps
  • Monitor mode requires kernel extensions
  • GPS requires additional hardware/permissions

Workarounds:

  • Client detection via ARP is sufficient for home networks
  • Security analysis doesn't require packet capture
  • Channel/rogue AP detection works with CoreWLAN API

Future Enhancements

Could Add:

  • Integration with external Kismet server
  • Bluetooth device detection
  • Network topology visualization
  • Automated remediation scripts
  • Export to Kismet format
  • Real-time monitoring mode

💡 Tips and Tricks

Maximizing Detection

For Best Client Detection:

  1. Run analysis shortly after devices connect
  2. Use network actively before scanning
  3. Clients appear in ARP table when communicating

For Rogue AP Detection:

  1. Run analysis in multiple locations
  2. Compare results over time
  3. Look for sudden new networks

For Channel Analysis:

  1. Run at different times of day
  2. Peak hours show true congestion
  3. Compare 2.4 GHz vs 5 GHz utilization

Interpreting Results

High Client Count (10+):

  • Normal for home with many devices
  • Consider network segmentation
  • Monitor for unknown devices

Multiple Rogue APs:

  • Dense urban area (neighbors)
  • Not necessarily malicious
  • Focus on evil twins and open networks

Congested Channels:

  • Switch to 5 GHz if possible
  • Use wider channels (80/160 MHz)
  • Consider WiFi 6/6E upgrade
