pdgmail: Backtrack: Forensics: RAM Forensics Tools: pdgmail

We received a request for an article for pdgmail which is a Python script that analyzes Windows and Linux browser process dumps where the browser had Gmail open. I was able to test on 32-bit Windows 7, 64-bit Ubuntu 10.04 LTS, and 32-bit Ubuntu 10.04 LTS. Unfortunately the methods I was using did not work properly on the 64-bit Ubuntu however it worked perfectly on both 32-bit operating systems I tested. Below I describe how pdgmail can be used to dump Firefox process memory using Process Dumper on Backtrack Linux which is technically Ubuntu 10.04 LTS.

PHP Script Using Exec Function & Launched From Crontab Hogging Server Memory

While working on a PHP script on a CentOS Linux server that runs from crontab I ran into an issue where PHP was bogging the server down because of memory use. The script has a lot of output that is not necessary to store though when using the exec function within the PHP script it was storing the unneeded output to an away which I believe was causing the memory usage problem. At first I thought I simply needed to modify the memory_limit setting within php.ini however that was not the true issue at hand. Below I describe two items to look at modifying if you run into a similar issue.

How To Delete A Profile On Xbox 360

Over the past couple of years I have had many friends use my Xbox 360 and in doing so they added their profiles to the device. Every time I want to login I have to sort through multiple profiles to locate the one I want to login with so I finally decided to clean up all of the profiles except for the primary one I use. You would expect the Xbox 360 interface to have a delete option directly from where the profiles are listed however it probably is not included there to cut down on accidentally deleting the incorrect profile. Below are instructions on how to delete profiles from your Xbox 360.

Install Backtrack 4 On Windows 7 In A Virtual Machine Using Windows Virtual PC

I have been using a Windows 7 laptop for quite awhile as my daily driver and recently wanted to install Backtrack 4 in a virtual machine so I wasn’t required to dual boot or use a different laptop for BT4. I thought about using VMware as Martin wrote an article a couple months ago about installing Backtrack in a VM on Windows 7 but a couple months ago I discovered Windows Virtual PC during a Windows XP VM install. So far I have been really happy with Windows Virtual PC and decided to try installing Backtrack 4 in a Windows Virtual PC virtual machine. Below are the details on how to setup the Windows Virtual PC virtual machine and then information on how to install Backtrack 4 in that VM.
