Several interesting things are to be reported. Firstly, the NET implant was designed first for the event, secondly, the maldoc are planned before the idea of the decoy document to download them. The Bipin account often comes up in Transparent Tribe campaigns, possibly it is responsible for the development of malicious tools, in this logic the other "Dell-R" account would be responsible for the templates of the decoys.The fact that the document is delivered after the celebration is not a problem in the logic that it should be given as a reward after the event, so the team could hang longer than if it would have an announcement related only to the day of the event.
