Using my dictionary and some research, I've found that there seems to be three words for "hacker" in Chinese. 黑客，骇客，and 红客. The first two look to just mean "hacker," while the third is a word for the implicitly state-supported private citizen in the PRC who hacks foreign enterprise out of nationalism. But does anyone know how to describe the verb for what these people do? My dictionary says to simply use 黑 or 骇, but what of the specific grammar cases when I need a two-syllable verb? Surely there's a better verb.
EDIT: After further searching, perhaps 侵入 would work? It seems to be a word with military connotations for "invade," but apparently can also mean to "gain unauthorized access."
