XPCSniffer

XPCSniffer will dump XPC information to a file and the console.

Usage

• Open up the Console.app on macOS
• Search for XPCSniffer on your device
• Output will be +[XPCSniffer] Writing to /var/mobile/Containers/Data/Application/APP_UUID/Library/Caches/XPCSNiffer.log
• SSH into your device and tail -f /var/mobile/Containers/Data/Application/APP_UUID/Library/Caches/XPCSniffer.log

Notes

• Update the filter plist with the Bundles or Executables you want to dump.
• Set DEBUG to 1 or 0 inside the Makefile for logging.
• Use jlutil to parse the bplist16 data.
