Astris, commonly stylized as astris, is an internal macOS tool used for debugging EVT (Evaluation Validation Test) and DVT (Development Validation Test) iDevices (devices with CPFM 00 or 01). It's meant for use with a Kanzi Cable, Kong Cable, GorillaSWD cable, or KobaSWD cable. (See Category: Cables)

This program can be used to dump the SecureROM of an iDevice, provided you have a compatible internal cable, with commands such as this one.

Another possible use of this program is debugging the Application Processor of an iDevice, allowing you to run any software you want on them, however this requires both an internal cable compatible with your device's Application Processor and a device with CPFM 00 or 01 (or at least one where the Application Processor has been demoted to one of those values).
