The digital systems used to control the railways , such as signalling , are under threat from cyber attacks with potentially fatal results , according to Alexander Gordeychik , a researcher at Kaspersky Lab in Moscow . There were four cyber attacks on the UK rail network during 2015 , although they were all exploratory and did n't attempt to cause any disruption , private security firm Darktrace said . " State - sponsored attackers are already inside critical infrastructure , " said Gordeychik . " And this is scary. In case of any maybe warfare , it could be an option to a cyber weapon against civil infrastructure . "
