Russian hackers have breached networks belonging to the US government and private organizations worldwide in a widespread espionage campaign that uses the global software supply chain to infect targets.

The US Treasury and Commerce departments are among the US government agencies hit in an operation that multiple news outlets, citing people familiar with the matter, said was led by Cozy Bear, a hacking group believed to be part of the Russian Federal Security Service or FSB.
