All over the world, in Dutch clubs like the one Kok frequented, or Australian biker hangouts and Mexican drug safe houses, there is an underground trade of custom-engineered phones. These phones typically run software for sending encrypted emails or messages, and use their own server infrastructure for routing communications.

For MPC, the process of setting up the devices was relatively simple: MPC would take a Google Nexus 5 or Nexus 5X Android phone, and then add its own security features and operating system, according to social media posts from MPC and a source with knowledge of the process. MPC then created the customer’s messaging accounts, added a data-only SIM card (which MPC paid about £20 a month for), and then sold the phone to the customer at £1,200. Six-month renewals cost £700, the source added. MPC only sold around 5,000 phones, the source said, but that still indicates the business netted the company some £6 million. At one point, a version of MPC’s phones also used code from an open-source, security-focused Android fork called CopperheadOS, three sources said.
