Remote Exploit – BackTrack 4 Beta released

BackTrack 4 BetaAfter demonstrating and still tweaking the nervously expected BackTrack 4 beta at shmoocon, it is now available for download from some number of official mirrors. There are several torrents named bt4 but believe they are full of malware. The Remote-Exploit encourages you to download it directly from them. They have made a big decision on this version – moved from from Slackware to (as we have seen) an Ubuntu server with

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.

Advanced Cross-Site Scripting

There have been some good papers in the past that should have woken folks up to the potential risks of XSS, but the problem is still prevalent and most security folks are not interested in the issue and its ramifications. I hope to change that perception with this paper and the release of a tool called XSS-Proxy that allows XSS attacks to be fully controlled by a remote attacker.

WPA broken PACSEC 2008 + Aircrack-PTW

WPA security brokenSecurity conference PACSEC 2008 that will be held in japanese Tokyo on 12th and 13th November 2008 has a great attraction. There will be presented a security research from Mark Tew as a next (not brute force), new implementation of the WPA-TKIP attack. WPA-TKIP security based on the dynamic key generation was supposed to be by laicks and professionals as unbreakable. Much more safe then funny WEP encription.

BackTrack Linux How to Extend battery life

BackTrack 3 Can your CPU do this? The idea is, I have a notebook and I want to extend the time of working on the nootbook without being pluged into the electric outlet. There are many possibilities how to do it. It definitely means that you have installed linux based operating system. You can save something by taking away modules that are unnecessary for hardware or by reducing the backlight of LCD. And what is the second biggest time glutton right after LCD?

Wired keyboard eavesdropping video

Sniffing keys Every press on the keyboard pruduces a small impuls of electromagnetic radiation. This radiation can be captured and easy (quickly) decoded. Even though the described attack effects only some keyboard models it is worth mentioning. Before the penetration test there was done a verification of eleven different keyboards. Each one was reciptive to one of four different methods of availabe attacks. As result see the videos bellow.

Naked Edimax EW-7318USg – Photogallery

edimax usb wifi adapter We were able to get pictures of USB wireless card Edimax EW-7318 USg taken to pieces. As you can see on the picture the hack antenna on the modele without connector for external antenna will be trivial. The mother board is at all models the same. If you have an older or “non-antenna” USB WiFi adapter Edimax you can go ahead doing modifications.No need to write more. The card without the driver modification works and injects almost at every Linux distribution.
