SIGHORSIN' AROUND (legacv gets swept)
Hi! It’s legacv. It’s mid-late June of 2025 and Purdue Hackers has just put out their latest baby, SIGHORSE, or Special Interest Group in Horsing Around. You can read more about it here, but the goal is simple: make whatever you want, but make something.
I had a few options to join:
- A bookkeeping tool for pentests, because my note-taking is not up to par;
- A website (the one you’re looking at) – making it more usable (on my side) and understanding Jekyll;
- Reading through Practical Malware Analysis by Michael Sikorski and Andrew Honig and doing the labs;
- Modeling an ICS environment to learn about modbus, HMIs, PLCs, and how to pentest them
The last option was, naturally, the most appealing for this SIG. Problem is I know nothing about ICS, and my soft hands have never worked in a factory, warehouse, or power plant. I’ll be making a series of blog posts documenting my journey, this being the first; up next should be a document on how I found all my resources, including papers, software, and hardware.
If you know anything about ICS security (at all), please feel free to shoot me a PM on Mastodon – legacv@infosec.exchange.
Go join SIGHORSE! Have some fun!
