With so much of life shifted online, it’s natural that elements of warfare will follow. From Michael Gallagher at the BBC:

“‘Sophisticated cyber attackers could do things like derail trains across the country,’ says Richard A Clarke, an adviser on counter-terrorism and cyber-security to presidents Clinton and Bush.

‘They could cause power blackouts – not just by shutting off the power but by permanently damaging generators that would take months to replace. They could do things like cause [oil or gas] pipelines to explode. They could ground aircraft.’

Clarke’s worries are fuelled by the current tendency to put more of our lives online, and indeed, they appear to be borne out by experiments carried out in the United States.”
