Several places, including Arik’s blog, Haaretz, and Schneir’s blog covered the case of Israeli industrial espionage using trojan horses transmitted to targetted companies. Apparently proprietary information was stolen from these companies via the trojan horse.

Quite interesting, take a read. But the part I love is that the guy got caught because he used to trojan horse to target his ex-father in law after a nasty divorce. Beautiful. High tech spy stuff, foiled by the basic human need to screw over the ex-wife.
