macOS Seatbelt/Sandbox Trace Script

macOS sandbox profiles used to be able to include a trace command that would write all the denied operations to a sandbox profile, allowing a profile to be iterativley built up. Apple removed that functionality for reasons explained below.

trace.sh examines the kernel log for the denied operations and creates the relevant allow rules in a sandbox profile, just like the sandbox profile trace command used to.

shrink.sh tries to reduce a sandbox profile to the minimum lines necessary.

It's very rough and ready at the moment (check the sed regex'es in the script to see what I mean) and needs more testing with a wider set of use cases.

# Ideally, wget -r should mirror a site, but modern websites are complex, this
# tries to fix the gaps of what is typically mixed.
# It's been tested on 3 or 4 sites, and likely needs more tricks added.

Using OSC7 to trigger a canary token in text files

macOS' Terminal.app supports the OSC7 escape code for notifying the terminal of the current working directory. It also supports the file:// URL scheme. This means you can embed a hostname in the instruction, and the host will perform a DNS lookup against it. It also won't visibly render in the terminal.

You can create the escape code like this: printf '\033]7;file://<hostname>\033\\'

I tested Terminal.app, Microsoft command shell, Windows Terminal and Alacritty and it only worked on Terminal.app. OSC7 support is contentious across other terminals according to various pull request discussions.

This was discussed in @stokfredrik's BlackHat/Defcon 2023 talk https://i.blackhat.com/BH-US-23/Presentations/US-23-stok-weponizing-plain-text-ansi-escape-sequences-as-a-forensic-nightmare-appendix.pdf
