Re: Pakistan Army Website?
well i believe you will have to check for National Communication Safety Board in Islamabad, they are the authority for this work.
Other than that ISI always puts up its vacancies through ads in newspapers, but they start with the term," A public sector organization" and ends up with some post box number, but people know that this post box means the ad is for ISI.
The mobile companies operations people have direct contact with these SIGINT setups in agencies due to LI interfaces (legal Interception). May be they can give you a cue or reference if you know someone there.
