When I heard there was going to be a TV drama about cybersecurity, my initial reaction was that it was a brave thing to attempt. Trying to make what we do televisual is notoriously difficult. There is very little to see – just people tapping at keyboards and staring at screens, with most of the action going on inside their heads. So I have been pleasantly surprised by Peter Kosminsky’s Channel 4 series The Undeclared War (whose second episode airs tonight). I binge-watched the entire thing in a weekend.
The cyber-attack on the UK in episode one was all too credible. I initially thought they were going to be vague and melodramatic – “The internet’s gone down!” – but the script went on to explain how the BT infrastructure, which does run a huge chunk of web traffic in the UK, had been taken offline. They specified how 55% of web access had been lost and it was cleverly timed to be a disruptive attack, rather than a disastrous one with planes falling out of the sky. You can cause a lot of chaos by taking out any of these “Tier 1 networks”. We’ve seen it happen by accident – last October, Facebook managed to wipe itself by mistake – so it’s perfectly plausible an attacker could do the same.
