Britain and the United States today released a rare joint statement warning of "malicious cyber activity" carried out by the Russian state.
The technical alert was issued by the UK's National Cyber Security Centre, the US Federal Bureau of Investigation and Department of Homeland Security. It warned everyone from internet service providers to home office customers to heed the warning, after the government agencies found cyber attacks targeting
devices such as internet routers.
They cited cybersecurity research organisations and other governments as providing evidence of such attacks, without providing details of their timing or scale. The joint statement comes amid worsening relations between the two countries and Moscow after Washington and London launched coordinated strikes against Russia's ally Syria.
