AireplayNG (Part 2)

This video explains about the filter options and replay options provided by the Aireplay NG. Aireplay NG is always used with some attack vector and depending upon the attack, you will be interested in some specific packets only. With the help of filter options you can filter the required packets for re-injection. Similarly, while re-injecting the packets you might have to alter some fields of the fields. With the help of replay options you can change different fields in the packet like frame control word or source, destination and BSSID MAC and so on.

Through understanding these options is the key for using the aireplay-NG effectively to crack the WEP key in small amount of time.

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.

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
