(Reuters) – The United States and Britain on Monday accused Russia of launching cyber attacks on computer routers, firewalls and other networking equipment used by government agencies, businesses and critical infrastructure operators around the globe.

Washington and London issued a joint alert saying the campaign by Russian government-backed hackers was intended to advance spying, intellectual property theft and other “malicious” activities and could be escalated to launch offensive attacks.

It followed a series of warnings by Western governments that Moscow is behind a string of cyber attacks. The United States, Britain and other nations in February accused Russia of releasing the “NotPetya” virus, which in 2017 crippled parts of Ukraine’s infrastructure and damaged computers across the globe, costing companies billions of dollars.

The Kremlin did not immediately respond to a request for comment. But Russia’s embassy in London issued a statement citing British accusations of cyber threats from Moscow as “striking examples of a reckless, provocative and unfounded policy against Russia.”
