After being in production for almost 6 months and on time for a Black Hat, Vegas release, BackTrack has been updated. It is called the BackTrack 4 R1 “BlackHat Edition”. This was released a few days ago at the BH Vegas.
“BackTrack is a Linux-based penetration testing arsenal that aids security professionals in the ability to perform assessments in a purely native environment dedicated to hacking. Regardless if you’re making BackTrack your primary operating system, booting from a LiveDVD, or using your favorite thumbdrive, BackTrack has been customized down to every package, kernel configuration, script and patch solely for the purpose of the penetration tester.“
This is the update log:
- A New kernel (2.6.34)
- Massively improved hardware support

Consider Grimwepa a front-end to many famous Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA) password auditors. We haven’t been able to use this one as we have been very busy with various assignments. But, still this is worth a mention.
Grimwepa is a password cracker for both WEP and WPA-encrypted access points (routers). It is written in Java and is intended for use with the Linux Operating System, more specifically for the BackTrack distro’s. It has only two modes: Crack WEP-encrypted access points (routers) and crack WPA-encrypted access points. It can search for new targets, and auto-selects your cracking method! Pretty much everything is done for you.
Grimwepa uses the following applications and suites:
- aircrack-ng suite:
o aircrack-ng, to crack WPA and WEP;
o airodump-ng, to capture packets and find access points;
o airmon-ng, to enumerate devices in monitor mode;
o aireplay-ng, to forge and replay packets;
o packetforge-ng, to create replay packets.
- iwconfig, to see if devices are in monitor mode;
- xterm, to show output to user;
- ifconfig, to get the MAC address of devices;
- macchanger, to change MAC address of wifi cards.
Since these applications exist on the current distribution of BackTrack, you can use this application without having to install all these.
A sample screen shot of Grimwepa:
The author built Grimwepa because the default cracker on BackTrack 4 did not work from him. It supports a lot of attack methods. Those are:
Attacks for WEP-encrypted Access Points:
- ARP-Replay attack
- Chop-chop attack
- Fragmentation attack
- p0841 attack
- Cafe-Latte attack
Cracking options:
o aircrack-ng is able to crack just about any WEP password after about 20,000 IV (Initialization Vector) data packets have been captured. The capture usually takes about 2 minutes, and the crack another 2-3 minutes.
Attacks for WPA-encrypted Access Points:
Basic de-authorization attack to get handshake.
Cracking:
o GRIM WEPA includes a 2MB default password list containing approximately 250,000 commonly-used passwords.
o Wordlist / Dictionary / Brute-force attack: Currently, there is only one consistent method of cracking WPA, and that is by brute force.
This is a Java application and so it could work on almost all *Nix distributions. Executing Grimwepa is also pretty simple. Just execute the following command:
java -jar grimwepa_X.X.jar
Here X.X is your version of Grimwepa.

It is yet another copy of Backtrack for GNU lovers! Most, or should we say all the tools list has been taken from Backtrack making it more like Backtrack but with different look and feel, which we can customise. For all lazy bones like us, this one is a good back up option if Backtrack is not able to boot under some circumstances.
GnackTrack is based on Ubuntu there is obviously going to be loads of references to Ubuntu throughout the distro.
There is not much to write about it now.
File size is about 1.25 Gb
