The Intuitive WiFi hacking GUI app for Ubuntu Linux

Ubuntu Linux černé logo Lets look at an interesting and 100% functional graphic extension for WEP/WPA crack pack of applications, aicrack-ng (airodump-ng, aireplay-ng, aircrack-ng). The application was tested in the reality, in the operating system Ubuntu 10.04 LTS Lucid Lynx. USB WiFi card used for the test is Alfa AWUS050NH. This card was bought thanks to your donations (check out text five wireless adapters for wireless hacking). The used driver is the original part of  Ubuntu Linux (rt2800USB). Besides the pack aircrack-ng and MDK3 there are specified for the error free functioning mentioned dependances: gtk-sharp2, libncurses5-dev, monodevelop, libqyoto4.5-cil, qyoto-dev.

Utilizing multiple CPU cores for password cracking

Cowpatty cracker logoAs the market with CPU has moved to multi-core solutions as a alternative method to increase computation power, intensive computing applications are not adapting to this fact so quickly. A Lot of people still don’t know that the system is not able to split tasks into more threads and distribute the work evenly upon the cores. This task is on the application developer who has to implement the multi-thread supporting mechanism.

Evilgrade Toolkit helping with fake updates

Evilgrade iconFrom the word compound of evil and grade, you see there will be something evil about this piece of software and upgrades. It is a modular framework for supplying clients with fake updates that can contain a wide scale of payloads. The problem of poorly implemented actualization routines has been well know for quite some time now, but it seems it has been greatly overlooked. In the time of creation Evilgrade (summer 2008), very popular software has been vulnerable to this kind of exploit such as

Aircrack-ng optimalization for CPU with SSE2

Aircrack logo There is a nice modified version of aircrack-ng I found on their website aircrack-ng.org. It is optimized for CPUs with the SSE2 instruction set (what is SSE2?). For classic dictionary attack on WPA key, it is able to speed things up to 500% compared a not optimized version. I made a test using BackTrack 3 with CPU Intel Core2Duo P8400 2.26 GHz, cowpatty 4.3, aircrack-ng 1.0 rc1 and aircrack-ng-wpa-sse2. For this test I will use a dictionary and a handshake (wpapsk-linksys.dump) from Cowpatty package. The results are on the screenshots.

Capturing WPA-PSK handshake

wpa-psk handshake WLAN Hacking – WPA-PSK handshake. The deauth atack with Aireplay-ng -0 wants to disconect the client from Access Point and after reconnecting get by tapping the handshake. But the process fails. Now what? Be aware that there is another (maybe better and easier) way how to get the data for crack WPA. Wireshark is a strong application and the technology that will be described can be used in other ways like for universal sniffing of the net traffic.

Aircrack 1.0 BETA .lzm BackTrack

backtrack pack aircrack-ng New lzm pack released. What is Aircrack? 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.

WEP Crack – video tutorial for beginners

video tutorial camera The “security audit” video tutorial posted from user of the airdump.net server. About 10 minutes long video shows step by step how to crack a WEP key. This most widely used airodump-ng, aireplay-ng & aircrack-ng attack can get under control everybody, so watch learn and try to crack your first WEP key. Tutorial mastered with the linux movie application xvidcap, on the operating system Backtrack 2. WiFi card used in the tutorial is Atheros based chipset hardware. For details see the video.

Intel Centrino Packet Injection WiFiSlax and ipw3945

wifislax logo Distribution used in the tutorial Wifislax 3.0. There is available a new version 3.1. Hardware: Intel Pro Wireless – centrino ipw3945. Program and applications Compiled aircrack-ptw and live distro wifislax. Target pentesting, wep key crack. Wifislax is a special pentest of a distribution that is developed by a spanish group called Seguridad Wireless. Primarily it fills the gap created by the development and by the new wifi chipset sales.
