US, British and other nuclear weapons systems are increasingly vulnerable to cyber attacks, according to a new study by the international relations thinktank Chatham House.
The threat has received scant attention so far from those involved in nuclear military planning and the procurement of weapons, the report said.
It blames this partly on failure to keep up with fast-moving advances, lack of skilled staff and the slowness of institutional change.
“Nuclear weapons systems were developed before the advancement of computer technology and little consideration was given to potential cyber vulnerabilities. As a result, current nuclear strategy often overlooks the widespread use of digital technology in nuclear systems,” the authors of the study said.
