Russian government spies are behind a broad hacking campaign that has breached U.S. agencies and a top cyber firm

The Russian government hackers who breached a top cybersecurity firm are behind a global espionage campaign that also compromised the Treasury and Commerce departments and other government agencies, according to people familiar with the matter, who requested anonymity because of the sensitivity of the matter.

The FBI is investigating the campaign by a hacking group working for the Russian foreign intelligence service, SVR. The group, known among private-sector security firms as APT29 or Cozy Bear, also hacked the State Department and the White House during the Obama administration.
