Wireless Communications

Last year we told about not so well know tool called MDK, as part of the “Cracking WEP key - Acces Point with pree-shared key (PSK” concept. Alot of time has passed by since then and now we have well workiong stable version even with GUI extension Charon. It was not much of a deal in Fall 2007, but the situation has changed. The autor has also decidedd to eneble the Destruction Mode in the menu. The extension is written in Java and is very stable. If you have not encountered the MDK tool before, it is a proof-of-concept tool from the authors of the PTW implementation in aircrack-ng (Darmstadt Lab). It tses 8 concepts of attacking wireless networks. b - Beacon Flood Mode sends beacon frames and confuses the client by creating fake APs. This is able to make AP scanning applications and devices unusable a - Authentication DoS mode sends auth frames to all APs in range. This results in freezinig or restarting devices p - Basic probing a ESSID Bruteforce mode sends probe requests to APs and

Finally there exists a way how to solve packet injection with driver for wifi card Intel WiFi Link 4965AGN – operating system Linux. The one modified is the original driver iwlwifi (included for example in distribution Backtrack Linux). Be aware that the packet injection is functional but still it is an experimental thing (develop version). Besides the complicated compilation and occasional unstability so far (September 2008) the aireplay-ng attack -9 (t.j test injection) does not work on 100%. Tutorial for packet injection Intel Pro Wireless 4965AGN (iwl4965) What do you need: - kernel 2.6.25 or higher*, - kernel sources, - compat-wireless-2.6 packet, - aircrack-ng (=””> RC1), - basic development tools (make, gcc, …), - injection patche for driver. Be aware that the instruction is for generic Linux. Your distribution, mainly in case of advanced packet administration (Debian, Ubuntu, etc.), can include required packets in source (then you don’t have to compile it manually from so
