What tech is Circles selling?

  • “Landmark” software: a network-based solution which allows users to “collect, process, validate and manage information for conducting intelligence operations, based on the location of mobile subscribers.”
  • “Voice Over Location Enabler (VOLE)” software: likely relies on the SS7 protocol to “remotely intercept targets’ incoming and outgoing voice calls” and their locations.
  • “Saphire” software: “allows a command to be sent to a mobile operator via a remote terminal to assign a new IP address to a specific device,” most likely for the targeted interception of communications.
  • “Pixcell” line of IMSI-catchers: described as a “tactical SIGINT [signal intelligence] system that intercepts voice data, messages, and internet data for specific cellular devices.”
