I think others have testified in front of this committee, including the NSIA, who has been here before, and our deputy minister, and named some of the countries that are primarily involved in this. We've seen China and Russia involved in this. I think the committee has heard that on a number of occasions.
There is also a lot of public reporting. We have CSIS reporting on this. We also have a rapid response mechanism annual report that I believe is publicly available and has been shared. I think all of these actually give the committee a lot of nuancing about who those actors are and the types of tactics they're using.
