AMSTERDAM (AP) — A Dutch newspaper and television show are jointly reporting that the Netherlands' spy service broke into the computers used by a Russian hacking group often nicknamed Cozy Bear and may be sitting on evidence relating to the hack of the U.S. Democratic National Committee.

Reports carried in the respected daily Volkskrant and the current affairs show Nieuwsuur say hackers working for the Dutch General Intelligence and Security Service penetrated the network used by the Russian cyberspies in mid-2014 and watched them for at least a year, even managing to catch the hackers on camera.

Cozy Bear is one of two Russian espionage groups that cybersecurity firm CrowdStrike says broke into the DNC ahead of the 2016 presidential election; the other is usually called Fancy Bear.

The Dutch intelligence service declined to comment on the reports Friday.
