Show 99 – I Always use a VPN – Thomas d’Otreppe – Aircrack-NG – OpenWIPS-NG

This week we are talking to Thomas d’Otreppe, author of Aircrack-NG and OpenWIPS-NG about his Open Source project and what they do ?



“Aircrack-ng is an 802.11 WEP and WPA-PSK keys cracking program that can recover keys once enough data packets have been captured. It implements the standard FMS attack along with some optimizations like KoreK attacks, as well as the all-new PTW attack, thus making the attack much faster compared to other WEP cracking tools. In fact, Aircrack-ng is a set of tools for auditing wireless networks.”



“OpenWIPS-ng is an open source and modular Wireless IPS (Intrusion Prevention System). It is composed of three parts:

  • Sensor(s): “Dumb” devices that capture wireless traffic and sends it to the server for analysis. Also responds to attacks.
  • Server: Aggregates the data from all sensors, analyzes it and responds to attacks. It also logs and alerts in case of an attack.
  • Interface: GUI manages the server and displays information about the threats on your wireless network(s).”

Components of Aircrack-NG:

  • Aircrack-ng (cracking WEP, WPA/WPA2)
  • airodump-ng
  • airmon-ng
  • airbase-ng
  • aireplay-ng
  • airtun-ng

General Topics

  • Comparison of Kismet and Aircrack-NG and OpenWIPS-NG.
  • use case and features for Wireless and Network Security Engineers.
  • Call for volunteers on the project! You can also find more about Thomas at WiFu

MEME: I don’t always use wireless at the airport…but when I do, I use VPN.
