Terrorising banks: Sure, no biggie -- right up until it happens for the eleventy-seventh time this year at YOUR bank, and you can't use your ATM/debit card/credit card...
Disrupting transit: Similar to above, but add in the perceived risk of actual physical harm.
Deliberately wrecking transit: "Highly unlikely"... like, say, crunching an airplane into a building on purpose?
Publishing false stories: Good thing bogus stories don't get spread by word of mouth as rumors...
Disrupting news sources: Unless, of course, one (or more) of them happens to be one you've come to use.
Penetrating Govt systems: Maybe not DoD, but how about something less "critical", like all the HEW records going into the bitbucket? Or hurricane predictions at the start of the season?
Actually GETTING secret govt data: Trusting soul, aren't you? What if Tim McVeigh and buddies had known where to steal some radioactive trash to add to their ANFO bomb?
Health services, et al: a hospital in England had to shut down for a while just from getting the Conficker worm; how much worse if somebody started screwing with meds? On a wide-spread basis? Or even just Operating Room scheduling, or billing? Hell, just patient admissions records?
Power grid: Hell with taking it down -- how about just borking it with unscheduled rolling brownouts, overvoltages, intermittently tripping random control relays, and so forth? Or just pushing supplies to borderline with a DDoS against the CoOps and the like?
Telecom systems: How happy would YOU be with a phone system that intermittently connected you to someone OTHER than the person you called? Or cell towers that randomly went out of service for varying periods of time? And if neither the phone company NOR the government or law enforcement could do anything about it?
TFA said that cyberterrorism isn't a credible threat yet -- which implies that it IS some threat, now. Me, I'm hoping they're not just whistling in the dark...
