Are droids hackable in the Star Wars universe?
For example, theoretically,
- could an Imperial hacker hack into C3P0's memory (let's say while the poor robot is in pieces in the Cloud City, before Chewie finds and rebuilds "him")? Could said hacker read and possibly alter C3P0's memories? Could he install "subliminal suggestions", in other words, viruses?
- could the Rebels hack, in the very beginning of "The Empire Strikes Back", into the Imperial Probe's AI remotely (via a WiFi or similar channel) and alter either or both the droid's perception (so that it sees only the snow fields, not the Rebel Base) and the signals it sends out, back to the Imperial recon divisions?
- could Imperial hackers aboard the Death Star hack into the attacking X-Wings' astromech droids (R2s) and cause the starfighters to crash into the walls or at least malfunction?
I know the idea itself feels somewhat strange to the world -- even though R2D2 does hack into the systems of the Death Star in "A New Hope", finding out where Leia is held captive and stopping the walls of the trash compactor before it would kill the "party" --, yet this day and age brings up such "technological updates" questions unavoidably as quite a number of the fans of the SW universe think about computers and systems with an up-to-date mindset.
Note: Should you feel interested, I have asked practically the same Q on rpg.SE with roleplaying games in focus.
