Unlike active scanners, Kismet operates in passive monitor mode, making it undetectable to the networks being assessed. It captures raw 802.11 frames, identifies access points, clients, probe requests, and encryption types without transmitting any packets. This skill covers deploying Kismet for comprehensive wireless security assessments, identifying rogue access points, detecting weak encryption, mapping hidden networks, and analyzing client behavior.\n\n\n## When to Use\n\n- When conducting security assessments that involve performing wireless security assessment with kismet\n- When following incident response procedures for related security events\n- When performing scheduled security testing or auditing activities\n- When validating security controls through hands-on testing\n\n## Prerequisites\n\n- Linux system (Kali Linux, Ubuntu 22.04+) with Kismet 2023+ installed\n- Wireless adapter supporting monitor mode (e.g., Alfa AWUS036ACH, TP-Link TL-WN722N v1)\n- Written authorization for wireless assessment (legal requirement)\n- GPS receiver (optional, for geolocation mapping)\n- Target environment wireless network documentation\n\n## Core Concepts\n\n### Kismet Architecture\n\nKismet uses a client-server architecture:\n\n- **kismet** - Main server process that captures and processes packets\n- **kismet_cap_linux_wifi** - Capture source for Linux WiFi interfaces\n- **kismet_cap_linux_bluetooth** - Capture source for Bluetooth\n- **Web UI** - Browser-based interface at http://localhost:2501\n\n### Wireless Frame Types\n\n| Frame Type | Purpose | Security Relevance |\n|------------|---------|-------------------|\n| Beacon | AP announces its presence | SSID, encryption, vendor |\n| Probe Request | Client searches for networks | Reveals preferred networks |\n| Probe Response | AP responds to client probe | Hidden SSID disclosure |\n| Authentication | Client authenticates to AP | Auth type identification |\n| Deauthentication | Disconnects client from AP | Potential attack indicator |\n| Association | Client joins network | Client-AP relationship |\n\n### Encryption Assessment\n\n| Encryption | Status | Risk |\n|------------|--------|------|\n| Open (No encryption) | Insecure | Critical - all traffic visible |\n| WEP | Broken | Critical - crackable in minutes |\n| WPA-TKIP | Deprecated | High - known vulnerabilities |\n| WPA2-PSK (CCMP) | Acceptable | Medium - depends on passphrase strength |\n| WPA2-Enterprise (802.1X) | Recommended | Low - certificate-based |\n| WPA3-SAE | Best practice | Low - resistant to offline attacks |\n\n## Workflow\n\n### Step 1: Prepare Wireless Adapter\n\n```bash\n# Identify wireless interfaces\niwconfig\n\n# Check adapter capabilities\niw list | grep -A 10 \"Supported interface modes\"\n\n# Kill processes that may interfere\nsudo airmon-ng check kill\n\n# Enable monitor mode\nsudo ip link set wlan0 down\nsudo iw dev wlan0 set type monitor\nsudo ip link set wlan0 up\n\n# Verify monitor mode\niw dev wlan0 info | grep type\n```\n\n### Step 2: Configure and Launch Kismet\n\nEdit `/etc/kismet/kismet.conf`:\n\n```ini\n# Data sources\nsource=wlan0:name=WiFi-Monitor,channel_hop=true,channel_hoprate=5/sec\n\n# Logging configuration\nlog_types=kismet,pcapng\nlog_prefix=/opt/kismet/logs/assessment\n\n# Enable all 802.11 channels (2.4GHz and 5GHz)\nchannel_hop_speed=5\nchannel_list=IEEE80211:1,2,3,4,5,6,7,8,9,10,11,36,40,44,48,52,56,60,64,100,104,108,112,116,120,124,128,132,136,140,149,153,157,161,165\n\n# GPS configuration (if available)\ngps=gpsd:host=localhost,port=2947\n\n# Alert configuration\nalert=ADVCRYPTCHANGE,5/min,1/sec\nalert=BSSTIMESTAMP,5/min,1/sec\nalert=CRYPTODROP,5/min,1/sec\nalert=DISASSOCTRAFFIC,10/min,1/sec\nalert=DEAUTHFLOOD,10/min,2/sec\nalert=PROBENOMFP,5/min,1/sec\n```\n\nLaunch Kismet:\n\n```bash\n# Start Kismet server\nsudo kismet -c wlan0\n\n# Access web interface\n# Open browser to http://localhost:2501\n# Default credentials: kismet / kismet (change immediately)\n```\n\n### Step 3: Conduct Assessment Scans\n\n**Rogue Access Point Detection:**\n\n```bash\n# Export device list via Kismet REST API\ncurl -u kismet:kismet http://localhost:2501/devices/summary/devices.json | \\\n    python3 -m json.tool > all_devices.json\n\n# Filter for access points\ncurl -u kismet:kismet \\\n    'http://localhost:2501/devices/summary/devices.json' \\\n    -d 'json={\"fields\":[\"kismet.device.base.macaddr\",\"kismet.device.base.name\",\"kismet.device.base.type\",\"kismet.device.base.crypt\",\"kismet.device.base.channel\",\"kismet.device.base.manuf\",\"dot11.device/dot11.device.advertised_ssid_map/dot11.advertisedssid.ssid\"]}' \\\n    > access_points.json\n```\n\n**Client Probe Analysis:**\n\nProbe requests reveal networks that clients have previously connected to, which can indicate:\n- Corporate devices connecting to insecure home networks\n- Devices searching for known-evil SSIDs (evil twin susceptibility)\n- Unauthorized personal devices in corporate space\n\n### Step 4: Analyze Results\n\nPython analysis script for Kismet database:\n\n```python\n#!/usr/bin/env python3\n\"\"\"Analyze Kismet capture database for wireless security findings.\"\"\"\n\nimport sqlite3\nimport json\nimport sys\nfrom collections

] Rogue/unauthorized APs identified and located\n- [ ] Encryption types documented for all SSIDs\n- [ ] Hidden SSIDs discovered and documented\n- [ ] Client probe requests analyzed for sensitive patterns\n- [ ] Evil twin susceptibility assessed\n- [ ] WPS status checked on all APs\n- [ ] Signal coverage boundaries mapped\n- [ ] Guest network isolation verified\n- [ ] Management interfaces not exposed on wireless\n\n## Best Practices\n\n- **Written Authorization** - Always obtain signed authorization before performing wireless assessments\n- **Passive Only** - Use Kismet in passive mode; do not transmit deauth frames or probe requests\n- **Comprehensive Channel Coverage** - Scan both 2.4GHz and 5GHz bands including DFS channels\n- **Multiple Locations** - Perform captures from multiple physical locations for complete coverage\n- **Time Duration** - Capture for at least 30-60 minutes to observe intermittent devices\n- **GPS Mapping** - Use GPS to create heat maps for signal boundary analysis\n- **Baseline Comparison** - Maintain an authorized AP inventory and compare against each assessment\n\n## References\n\n- [Kismet Documentation](https://www.kismetwireless.net/docs/)\n-
