Persistent, enterprise-class spyware is an underestimated problem on mobile devices. However, targeted attack scenarios against high-value mobile users are a real threat. Citizen Lab (Munk School of Global Affairs, University of Toronto) and Lookout have uncovered an active threat using three critical iOS zero-day vulnerabilities that, when exploited, form an attack chain that subverts even Apple’s strong security environment. We call these vulnerabilities “Trident.” Our two organizations have worked directly with Apple’s security team, which was very responsive and immediately fixed all three Trident iOS vulnerabilities in its 9.3.5 patch.

All individuals should update to the latest version of iOS immediately. If you’re unsure what version you’re running, you can check Settings > General > About > Version. Lookout will send an alert to a customer’s phone any time a new update is available. Lookout’s products also detect and alert customers to this threat.

Trident is used in a spyware product called Pegasus, which according to an investigation by Citizen Lab, is developed by an organization called NSO Group. NSO Group is an Israeli-based organization that was acquired by U.S. company Francisco Partners Management in 2010, and according to news reports specializes in “cyber war.” Pegasus is highly advanced in its use of zero-days, obfuscation, encryption, and kernel-level exploitation.
