Free CTF and Digital Forensics Resources

Are you interested in the forensic side of information security? Want to hone your pen testing skills but not sure where to start? Heard of reverse engineering, but it seems like a black art?

This article is a link dump (so it might go out of date, sorry) of free tools and resources to help you along the way. It started from an email I sent to a security analyst who was interested in learning more about this field.

My interests lie more in cybersecurity risk and management, rather than this low-level, detail-orientated stuff. Yes, that is my way of saying, “No way would I be good enough to reverse engineer malware.” But if I were going to get into this field, this is where I would start.
