How to protect yourself from cyberattacks
U.S. military and other intelligence agencies have been tracking hackers for years, and now it appears they are using new tools to target their own networks.
The U.K. National Cyber Security Centre said Tuesday that it had detected an unusual spike in cyberattacks from the Russian state-backed Cyber Army, which has long been targeting American companies and government agencies.
Cyber Army is also known as Fancy Bear, a nickname used by Russia and the U.s. government to label its most active adversaries.
U.N. Secretary-General Antonio Guterres condemned the attacks, which he called an act of war.
U.S.-Russian relations were damaged further in November when Russia announced it was deploying advanced cyber weapons in Syria.
