Cyberbreach at Rideau Hall was ‘sophisticated’ intrusion, internal documents reveal

Jim Bronskill reports:

Newly disclosed documents reveal the breach of an internal computer network at Rideau Hall was described to senior government officials as a “sophisticated cyber incident” in the days before the public was told of the security lapse.

Internal government emails, obtained by The Canadian Press through the Access to Information Act, also say officials were “unable to confirm the full extent of the information that was accessed.”
