If you take only the movies as canon, hacking is mostly not part of the Star Wars universe. Only highly specialised droids like R2-D2 are seen doing it, and he is shown to be a highly exceptional droid at that (there are many R2 units around, but R2-D2 is shown to impress other characters with its resources, showing he is "above average R2"). Among other things, droids do not seem to be networked unless explicitly and physically connected: wireless communications are only used as a holographic substitute of the telephone (there are cables everywhere in Star Wars).

In the expanded universe, however, there are some examples of movie-like hacking.

If your question is mostly about the mechanics, the Star Wars RPG by WEG (usually called Star Wars D6) has the Technical -> Computers (p62) and Technical -> Droids (p63) skills precisely for this kind of actions. Note that it is assumed that droids and computers are different things, and that the hacker needs physical access to the system: "The programmer must have access to a computer or datapad, which must be jacked directly into the droid's memory for programming" (p63). All page numbers refer to the 2nd edition revised rulebook.

Unfortunately I do not have my d20 rulebooks handy, but there is probably one or two skills for that too in Star Wars d20 (SAGA or not), probably depending on Intelligence and trained only.
