UK's rail signal upgrades 'could be hacked to cause crashes'
A hi-tech signalling system that will eventually control all of Britain's trains could potentially be hacked to cause a serious crash, according to a scientist who advises the government. Network Rail, which is in charge of the upgrade, acknowledges the threat. "We know that the risk [of a cyber-attack] will increase as we continue to roll out digital technology across the network," a spokesman told the BBC.
"Certain ministers know this is absolutely possible and they are worried about it. Safeguards are going in, in secret, but it's always possible to get around them." He added that part of the reason that transport systems had not already been hacked as frequently as financial institutions and media organisations was that much of the technology involved was currently too old to be vulnerable. All of that will change in the coming years, as aircraft, cars and trains become progressively more computerised and connected, he said.
