Dutch spies 'caught Russian hackers on tape'

American spies were so grateful they sent the Dutch cake and flowers, reports say.

The Dutch spy service broke into computers used by a powerful Russian hacking group and may be sitting on evidence relating to the breach of the US Democratic National Committee, reports say.

Respected daily newspaper Volkskrant and TV current affairs show Nieuwsuur said hackers working for the Dutch General Intelligence and Security Service penetrated the computers used by the group, often nicknamed Cosy Bear, in mid-2014 and watched them for at least a year, even catching them on camera.
