One of the evidence items during the 2022 Magnet User Summit CTF was a full file system extraction of an iPhone running iOS 15. Recently the CTF creators made the evidence (and corresponding challenge questions) available at CyberDefenders.org. You can register for a free account and then download the evidence.

Version 6 of Magnet Axiom added support for YARA rules. By default the installation ships with the free Open-Source YARA rules from Reversing Labs. These YARA rules may be updated within Axiom periodically. In addition to the included rules, AXIOM supports adding your own YARA source folders.
If you need to update the included rules on demand, you can do so with a PowerShell script and the GitHub CLI. The script below can be used to update the included rules, as well as other YARA sources you may be using within Axiom.
Prior to running the script you’ll need to install GitHub CLI
Once installed run gh auth loginto establish authentication with GitHub
When running the script you will need to run as an Administrator in order for the file-copy to ~\ProgramFiles to be successful
Set the working directory to the local git repository for the YARA rules
