Endlich ist der zweite Teil von diesem Artikel erschienen. Lange mussten wir warten, aber ich bin sehr ueberrascht. Zwar kurz gehalten, aber immer noch hohes Niveau und verdammt interessante Theorien.
WEP: Dead Again, Part 2 (http://www.securityfocus.com/infocus/1824)
In part one we examined the latest generation of passive WEP cracking tools that use statistical or brute force techniques to recover WEP encryption keys from captured wireless network traffic. This time, in the second and final article, we take a look at active tools that use 802.11 transmissions to attack WEP networks.
All of these active wireless attack techniques discussed in this article require the ability to inject arbitrary packets onto a wireless network. Although a variety of injection methods are available, most require Linux, are unsupported, and use hacked drivers that have support and availability problems. All of them require at least one wireless PCMCIA card based on the Prism2 chipset (such as the Senao 2511-CD-PLUS). Fortunately, the Auditor Security Collection live cd-rom can save you a number of headaches as it includes ready-to-use drivers for several active attack tools.
Beware of network disruptions that can be caused by active attacks. Using these tools may have unpredictable effects in various environments. In my testing, I have encountered a few systems that had to be rebooted in order to function again after being bombarded with injected packets.
