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. There’s several recommended tools listed in the challenge summary. For me the tools used were:
I had a wonderful time participating in the Magnet User Summit, both in person and virtually. After 2 years of participating virtually, it was my first time attending the Summit in person. It was great to meet for the first time in person, not just many of my coworkers, but many of the regulars in my Twitter stream as well. What a gathering of brilliant, yet equally humble, investigators.
During the Summit I participated on a panel about Bringing your Forensics Lab to the Cloud. I also had fun co-presenting on two talks, Walkthrough of a BEC (Business Email Compromise) and. Walkthrough of a Ransomware Investigation, where we looked at the examinations from a Law Enforcement and from a corporate perspective.
There was the surreal moment of realizing that the boss doesn’t just rock, he ROCKS!
This year there was an in person and a virtual CTF with separate evidence and challenges. For the in-person CTF we examined a Linux laptop and an iPhone. Also, the long anticipated Dark Mode is a treat for the retinas.
For the virtual CTF the evidence sources were a Windows image and an Android mobile device, and a Google TakeOut. I surprised myself with how well I did on the Android and that hasn’t been my area of expertise.
During the virtual summit I enjoyed sharing my presentation, Free Tools for DFIR Triage Collections. Special thanks to everyone who engaged with me during and after the presentations, and from all different time zones. Your support was very much appreciated.
