While we observed multiple iterations of this lure, metadata shows that the original document was created by a speaker at the Nuclear Deterrence Summit and then modified by the threat actors. The content of this lure suggests that it was likely targeted towards conference attendees and/or others who had an interest in what took place at the conference. This particular document was previously referenced in a report by ESTSecurity, and its embedded domain was included in a report by the Agence Nationale de la Sécurité des Systèmes d'Information (ANSSI). This indicates that the Autumn Aperture campaign was likely a continuation of a previously reported activity from this threat group.
