Cyberwar is not coming to the US – it’s already here

As recent high-profile hacks show, cyberwar is a very real danger and is likely to get much worse, says a US security expert

As the recent hacks of the Democratic National Committee and presidential candidate Hillary Clinton's campaign have shown, cyberwarfare has reached US shores - and it's likely to get much worse, says Kenneth Geers, a senior research scientist with cyber security firm Comodo.

Speaking to an audience at this year's BlackHat security conference in Las Vegas, Geers declared cyberwar a real and present danger.
