What astounds and upsets me is that we've been studying this for months, wondering about it and wanting to prevent it. Personally, I'm not in the intelligence service, but on December 15, 2021, I found a document on the web about the APT31 attack campaign.
Honestly, I would have expected the Communications Security Establishment, or CSE, to give us the details and the techniques. The newspaper Le Monde describes how APT31 works. That's why, for me, it's important to know when you knew, but also whether the techniques were clear. You can find out by doing the research yourself.
The CSE could have corrected the situation. Are you satisfied with the service provided at this time, in an emergency situation?
