The Undeclared War is a new drama series about a widespread hack on the UK’s computer networks. Here’s what experts say could really happen, including lethal drinking water, runs on banks and panic buying:
: “Imagine queues at petrol stations, now replicated at cash machines, as people panic to get money out because they’re worried that an attack against the banks could stop them accessing their funds. If all of a sudden tomorrow, our cards stopped working.
Fortunately, a worker spotted what was happening live on-screen and intervened, but the fact that hackers were able to break in, remotely, to a physical and crucial part of state infrastructure showed vulnerabilities in the system. Some months later, the Colonial Pipeline, which carries nearly half the US east coast’s fuel supplies, was disrupted by a cyber attack in a similar way.
Earlier this year, i has learnt, the NHS carried out a “tabletop” wargaming rehearsal of a major nationwide cyber attack, codenamed Exercise Denim, and will repeat this later this year. Mr Moles said: “If you haven’t already planned, how are you going to respond when you’re hit? David Mahdi, chief strategy officer at cyber company Sectigo and an adviser on cyber security to the Canadian government, said of the UK’s preparedness: “Do I think they’re ready? No. Do I think they have an idea of where they need to go? Yes.”
The “five eyes” group of intelligence-sharing between the UK, US, Canada, Australia and New Zealand was created to focus on preventing physical war but this has now extended to tackling cyber war, Mr Mahdi said. The “bad actors” are typically hostile states, such as Russia, Iran and North Korea, as well as underground hacking groups or “families” that often work hand in hand with those countries.
Bill Conner, who has advised GCHQ, Interpol and Nato on cyber security and is president and CEO of SonicWall, told: “When you look at what’s happened here in the States, like Colonial Pipeline, our water system, our electrical grids – even though our electrical grids are very different than the UK – they’re still very vulnerable. Our healthcare systems are vulnerable.”
