UK's Trident nuclear submarines 'vulnerable to catastrophic hack'

Thinktank sceptical about MoD assurances, saying cyber-attack could lead even to 'exchange of nuclear warheads'

The UK's Trident submarine fleet is vulnerable to a "catastrophic" cyber-attack that could render Britain's nuclear weapons useless, according to a report by a London-based thinktank.

The 38-page report, Hacking UK Trident: A Growing Threat, warns that a successful cyber-attack could "neutralise operations, lead to loss of life, defeat or perhaps even the catastrophic exchange of nuclear warheads (directly or indirectly)".
