I would think hacking was very rare skill in Clans. (future of the 80s sort thing.) I would think it was tech/scientist caste task to do. Not a Warrior.
I could see hacking as a necessary Dark Caste skill as they are trying to get information on where Clan raids will be, where Clan supplies are located, etc.
The Clans have to defend themselves against that sort of 'attack', so have their own team organization:
Warriors: in charge of the operation
Scientist: detailed computer programmers/forensic analysts, who create new programs for the technicians to use and automated systems to monitor their networks, while performing detailed breakdown on whatever the Technicians find and aren't able to identify
Technician: uses the computer programs and tools that the Scientists have developed to make sure the Clan computer networks are secure, along with tracing any connections back to see where the hack originated.
The problem is when senior Warriors wonder if the Computer security personnel are worth their resources and start to openly question the need for the group:
Star Colonel: "Your technical team has not spotted any attacks against our computer networks in the past two months. Is your team still necessary?"
Star Captain: "Are you saying that my team should only be allocated their resources when a Dark Caste attacker is attacking, quineg? Or does my team have to demonstrate what might happen if they were not standing guard over our computer systems?"
Star Colonel: "Ah, neg."
Star Captain: "Think of it this way. In a Mech duel the winner will come back with most of their armor remaining. Was that armor a waste since it was not used?"
Basically the Warrior in charge has to balance the complaints of:
"Everything is working fine, why did we allocate these resources to you?" and "Nothing is working, why did we allocate these resources to you?"
