Sweet QuaDreams: A First Look at Spyware Vendor QuaDream’s Exploits, Victims, and Customers - The Citizen Lab – 2023

Based on an analysis of samples shared with us by Microsoft Threat Intelligence, we developed indicators that enabled us to identify at least five civil society victims of QuaDream’s spyware and exploits in North America, Central Asia, Southeast Asia, Europe, and the Middle East. Victims include journalists, political opposition figures, and an NGO worker. We are not naming the victims at this time.
We also identify traces of a suspected iOS 14 zero-click exploit used to deploy QuaDream’s spyware.

The exploit was deployed as a zero-day against iOS versions 14.4 and 14.4.2, and possibly other versions. The suspected exploit, which we call ENDOFDAYS, appears to make use of invisible iCloud calendar invitations sent from the spyware’s operator to victims.
