Unpackers
I hate LANDESK and McAfee. I have been given a laptop with a pretty decent config but with these 2 pre installed. I can't remove these ( technically I can ).
However, this is about, unpacking and unraveling some techniques.
LANDESK helps in maintaining the IT infrastructure fairly decently, but i hate it because of the fact that it is loaded with so many shit.
Let us say you are assigned with the new machine and it gets into electronic record books, and there is a set of applications for your function / department that you must use on the machine, LANDESK will push these applications and get those installed silently in your machines. For pushing these, bigger applications are packed and stored in a central repository. This is replicated across geographical locations.
I would not get into detail of how these gets pushed etc... however, with the help of landesk and logon scripts, it is also easily possible to find what unnecessary applications are installed, and eventually removed too.
The crux lies in accessing the packs, unpacking those. Entire application setup with necessary customizations is converted into single executable. These executable get downloaded to your local temporary directory, and get installed silently. These packages have extra small utilities to report the installation to appropriate owners for that pack.
To safely use these, one needs to unpack the single large exe to source from which the pack was made,most of the time Universal Extractor ( legroom.net ) will work.
With the latest packages were not working. I was not able to find a PE investigator which would tell me the details about packing.
Far Manager (farmanager.com) came in handy which helped me to look through / extract as though the exe was like a zip file ( in a way yes ). However, using far manager is tedious, since it is CUI application.
Happy!!I got what i wanted :)
