@Ziggurat I don't know of any system which does this. BUT my gut reaction is to simply make any kind of "hacking" skill less broad.
Requiring the player to either gain profeciency with the hacking skill towards different kinds of tech; as they advance.
OR
Breaking it down into less broad skills. I.E.
* Cryptography (decrypting encrypted data)
* Network Access/Device Penetration (getting into a device at a distance)
* Privilege Escalation (Your into the system, but now you need to trick it your an admin.)
* Scripting/Programming (Your miscellaneous reprogramming a device skill).
@subtext Something I've used in a handful of campaigns. is the "Deck of Many Answers".
It appears as a deck of blank faced tarot sized cards. If discarded, the card vanishes and returns to the deck.
If a player asks a question before drawing a card, the card contains a hand drawn sketch attempting to illustrate the answer to the inquiry, but never with text or numbers. However, the deck is not omniscient and it's answers getting increasingly symbolic and open to interpretation the more abstract or game breaking; the players inquire.
Usually found by players, with no instructions.
Figuring out the shtick usually provides a lot fun, and they end up being MILDLY useful should players get the hang of them.
