On Monday, the US Department of Homeland Security, the Federal Bureau of Investigation and the UK's National Cyber Security Center jointly issued a technical alert.
The months-long campaign saw hackers attempt to compromise "millions" of devices - including routers, switches, firewalls and network intrusion detection systems - and officials have that the sustained effort could have been used for espionage, the theft of intellectual property or for "use in times of tension".
"We have high confidence that Russian Federation has carried out a coordinated campaign to gain access to enterprise, small office, home office routers known as SOHO routers and residential routers, and the switches and connectors worldwide", said Rob Joyce, special assistant to the President and cybersecurity coordinator at the White House, speaking to journalists.
Russian government-sponsored hackers are compromising the key hardware of government and business computer networks in like routers and firewalls, giving them virtual control of data flows, the USA and Britain warned Monday.
"When we see malicious cyber activity, whether it be from the Kremlin or other malicious actors, we're going to push back", Joyce said.
It's warned that a Russian government campaign to exploit these devices threatens safety, security, and economic well-being of the United States and the UK.
Today, we reported that UK Prime Minister Theresa May has been briefed on a possible incoming Russian-based cyberattack that could heavily compromise the country and release compromising information about the country's lawmakers.
While it the extent of the attack remains unclear, Ciaran Martin, head of the UK's NCSC, noted that numerous machines targeted had been "seized by hackers", adding that hacks were being tracked by British intelligence from a year ago. Lastly, the alert outlined what erratic hardware behavior should indicate if a device has been already compromised.
Ciaran Martin, head of the NCSC, said Russian Federation was: "our most capable hostile adversary in cyber-space, so dealing with their attacks is a major priority for the National Cyber Security Centre and our U.S. allies".
Russian Federation is being accused of a massive campaign to undermine the security of firewalls and routers in a bid to support espionage and future attacks. Jeremy Fleming, the Director of United Kingdom intelligence agency GCHQ also recently called out Russia's actions in cyberspace.
