The Remote Exploit Development Team has just announced BackTrack 4 Beta. BackTrack is a Linux based LiveCD intended for security testing and we’ve been watching the project since the very early days. They say this new beta is both stable and usable. They’ve moved towards behaving like an actual distribution: it’s based on Debian core, they use Ubuntu software, and they’re running their own BackTrack repositories for future updates. There are a lot of new features, but the one we’re most interested in is the built in Pico card support. You can use the FPGAs to generate rainbow tables and do lookups for things like WPA, GSM, and Bluetooth cracking. BackTrack ISO and VMWare images are available here.

OpenSuse and Ubuntu are perfectly serviceable Linux distros, but we’ve had a soft spot for BackTrack from the very start. Good news for us, since yesterday was the long awaited release of BackTrack 3 Final. It uses the same 2.6.21.5 kernel as before (to maintain WiFi injection compatibility) and Nessus is still out, but it is not without a great deal of other improvements. Its forensic capabilities are better than ever, largely due to included apps like a fully functional version of SAINT and a special version of Maltego made just for BackTrack. The download is free, but Remote-Exploit is asking users not to distribute it without notifying them first, because they’re trying to keep track of the number of downloads.
