Pcap2air

Pcap2air is a part of airbase suite of products. As the name suggests pcap2air tool injects the packets in pcap file on to the air i.e. wireless IEEE 802.11 interface. The input to pcap2air tool will be the file containing wifi packets in standard pcap format. Pcap2air will read those packets and inject them on to the 802.11 wireless interface specified in the command line options.

While injecting the packets pcap2air also provides the option for changing the bssid, source address and destination address of the user’s choice. This way it becomes easy for the wireless researchers and wireless engineers to test their products. For the process of cracking the WEP key, lots of packets with different IVs are required. With the help of pcap2air tool, one can keep on generating such packets for which AP or station will respond (e.g. ARP request packet) and every time the response will be with new IV. This way cracking process can be stimulated by orders of magnitude.

The video demonstrates the use of pcap2air tool and also comments on the different command line options supported.

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
