Depends on their resources, and their level of paranoia.
If the online game I'd had my last Hacker-adept in had run long enough, he'd'e ended up bugging everyone's commlinks, vehicles, lifestyles,
everything he could possibly have done. BEcause, well, he actually was
paranoid.

But other characters? They don't know, and more, they generally don't
want to know, outside of biz, and maybe going as far as "drinking buddies". The less they know about their team-mates outside the biz, the more they can justifiably conceal about
their own self in turn.
