iOS 14.x devices contain a hidden feature for sniffing decrypted HTTP/HTTPS traffic from all processes using the CFNetwork framework into an HAR format. To trigger this feature on a jailbroken device, you can simply place the correct configuration for com.apple.CFNetwork and trigger the com.apple.CFNetwork.har-capture-update notification.

Since this capture triggers syslog lines, which can be associated with their producing image name and pid, we can also connect each request-response to their corresponding process and the image name which triggered it.

This project is just a simple utility for using this feature.

iOS 13.x or under don't have this feature.

If you would like to build yourself using Theos, simply use make package.

I've already supplied with all the necessary binaries, so you don't have to. You can just install the .deb file found in the packages subdirectory, or use the compiled bin/harlogger.

After deploy, simply run on the remote device:

# trigger monitor HTTP/HTTPS traffic for the next 120 seconds
harlogger 120

# or just trigger for infinity. once this is done, it should be enabled even
# for software upgrades
harlogger --infinite

Now you can just run locally:

./remote_har_listener.py -o out.har

When hitting the Ctrl+C, the script should exit and dump all captured entries into given output file, if any.

The output should look like:
