Hackers destroy blast furnace in German steel mill
A recent report by Germany's Federal Office for Information Security reveals that hackers caused "massive" damage to an unnamed steel mill. They did so by manipulating and disrupting control systems to such a degree that a blast furnace could not be properly shut down. The report doesn't name the plant or indicate when the breach occurred.
This is only the second confirmed case in which a wholly digital attack caused physical destruction of equipment. The first case, of course, was Stuxnet, the sophisticated digital weapon the U.S. and Israel launched against control systems in Iran in 2008 to sabotage centrifuges at a uranium enrichment plant. Industrial control systems have been found to be rife with vulnerabilities, though they manage critical systems in the electric grid, in water treatment plants and chemical facilities and even in hospitals and financial networks.

And there's nothing special about USB... ANY WAY you get data into a secure network, from the un-secured rest of the world, is an attack surface. DVD-Rs are just as vulnerable as USB thumb drives. Glue-shut all the ports you want, and you'll still need to exchange data, and however you do that will leave you open to attack.
