So, another hidden thing in the game:
Successfully hacking stuff with your specialists, increases their hacking stat. It increases it by 5 and I'm told that it's only limited to one increase per mission, however, it does work. It's somewhat hidden because the game lies to you - you can only see the true hacking stat while hacking - the one you can pull up while viewing the soldier is NOT accurate. Hacking terminals and guard towers, as well as skullmining all count for the purpose of the increase, however, Haywire doesn't.
