AireplayNG (Part 1)

AireplayNG is a part of AircrackNG suite of products and is used for re-injecting wireless 802.11 frames on to the specified channel. The main aim of aireplay-NG is to generate large amount of traffic so that it can be used later for cracking the WEP or WPA-PSK keys with the help of aircrack-NG. The input to Aireplay-NG will be either the pcap file which needs to be injected or the interface name, as aireplay-NG is even capable of capturing packets on the wireless interface.

There are 4 types of command lines options that can be given to aireplayNG.

• There are 4 types of command lines options that can be given to aireplayNG
• Filtering options: Used on packets captured on interface/ read from file
• Replay options: Used while re-injection
• Attack method: The attack to be used while re-injection

In this Aireplay-NG tutorial video series, this video explains the process of WEP cracking in detail and explains the exact role of aireplay-NG in WEP cracking. Following 4 videos talk about the correct usage of the above options and also demonstrate all the options in detail.

Amit Vartak, 27 is working in wired and wireless security fields since last 3-4 years. His current area of interest includes IEEE 802.11 (Wi-Fi) suite of protocols, vulnerabilities in these protocols and countermeasure for those vulnerabilities. Working on cutting edge tools and technology always keeps him busy. He has contributed from concept level to final prototyping for the presentations in Defcon 2007 (The Emperor Has No Cloak - WEP Cloaking Exposed) and Toorcon 2007 (Caffe latte attack). He holds 2 patents with USPTO (current status: Patent Pending) and a few papers in IEEE journals on wireless protocol vulnerabilities. Prior to this, he was working on MEMS (Micro Electro Mechanical Systems) and has published a few papers in SPIE and ICMAT. (Yeah… kindda orthogonal fields… but technology really doesn’t limit the talent :) He did his masters in Electrical Engineering from one of the premier institutes in India, Indian Institute of Technology, Bombay (IIT-Bombay) and his under graduation, from University of Mumbai in Electronics and Telecommunication Engineering. He is currently working with AirTight Networks Inc. as a team lead in technology group since last 3 years.You can get in touch with him at amitcv[at]gmail[dot]com
