“Terror Contagion” opens at Montréal’s MAC. Centre stage is Forensic Architecture’s Digital Violence: How the NSO Group Enables State Terror, which probes the Israeli technology firm behind Pegasus, malware used to monitor the calls, emails, texts, and sensor data of activists and dissidents worldwide. At MAC, these findings are presented in an immersive installation featuring data sonification by Brian Eno and narration by Edward Snowden, and complemented by Laura Poitras’ latest film, documenting the research.
