Ever located an old capture file and you weren’t sure what was in it or needed to grab some quick statistics about another capture file? What about needed to run statistics on multiple capture files and present them via a database or a spreadsheet? Well if you have ever run into any of these scenarios then capinfos is worth a look. The capinfos command is available via the Backtrack CLI and provides statistic information about cap files. This is one of the gems located on Backtrack that nobody ever hears about.
Recently some pretty major advances have come around in the world of GPU based hash cracking. Up untill now there was not much for Linux which would utilize multi GPUs to crack password hashs. This has been changed with the release of Oclhashcat. The release of oclhashcat signifies a signifigant jump in the speed on linux based GPU systems. There is also a cpu based version called hashcat but for this article I will be reviewing oclhashcat
make: *** No rule to make target -largtable2, needed by ../../bin/linux/release/CUDA-Multiforcer. Stop.
When attempting to compile the CUDA Multiforcer on CentOS Linux I ran into an error because the argtable2 package was not installed on the server. The CUDA Multiforcer application is a security audit tool used to check the strength of MD4, MD5, NTLM, and SHA1 password hashes. The CUDA Multiforcer attempts to brute force one of those types of hashes by attempting every combination of characters specified such as lowercase only characters, lowercase characters and numbers, etc. This tool can be extremely beneficial for checking the strength of user passwords for various operating systems and/or applications that store their passwords in a MD4, MD5, NTLM, or SHA1 hash. As you can see in the below error the issue appears to be with argtable2 which is not a package available with the default yum repositories on CentOS. Below I display the error and describe what repository to install to be able to use yum to install the argtable2 RPM package.
