As 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.

From 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
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.
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.
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.
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.
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.
Update. The project is stopped for now (last check and the news last update in september 2008 ). Be patient and hope ‘ll be continue. In the forum you can view topic with screenshots and url to interesting GUI application for Windows users called AiroWizard. It’s graphic tool (interface) for Windows aircrack-ng suite and applications included in the pack. It provide GUI interface for manipulating with card and applications in the pack.
