It’s pronounced like the title says.
Anything else is just wrong. You heard me Killswitch.
I had some requests to provide my take on the OSI model separately from the presentation I made at PwnSchool, so here you go… the most comprehensive, authoritative version of the OSI model ever presented.
Two posts in one night, because I’m catching up on some backlog items. I’ve been teaching/training a team on PenTesting lately, and it’s caused me to think through some personal truths and approaches that I’ve taken for several years. While going through that process I came to realize that I’d never really formally codified them; this is my attempt to do just that. It all comes down to what I’m now going to call the “Four Three Rule of Team PenTesting”.
I realized I didn’t have any good notes on Radio Frequency Identification (RFID) tags/badges/etc, so I figured it was time to compile that and update it while I’m at it. This post is just a quick run-down of the frequencies, types, and common cards/IDs. If you don’t know what an RFID is, for the purposes of most pentesting it’s a security badge or a key fob, like you can see in the image at the top of this posting.
I have to teach some folks how to find, isolate, and analyze signals tomorrow, which of course means this is the perfect time to document some quick steps for my own reference. I started the build out from the DEFCON 26 Hardware Hacking Village Kali Live Build. If you don’t have it your mileage may vary… on to the buildout.
I’ve been taking photos of all the badges/SAOs/Challenge Coins/etc I collected at DEFCON 26. I’m sure I’ve missed a few, but in no particular order here are the images so far, with a quarter for size reference. I’ll be making very high resolution images of most in the future, but now these will work.
I made a presentation a few months ago based on a simple question I relieved… “What is all that stuff in your backpack?” I normally carry, well, more than I really need. Full list with links is below, or here’s the presentation for those who want to see it in all its original, horrible glory. Ever wonder what types of stuff I normally carry when on a pentest? Well, now you know. Enjoy!
I maintain a modified version of Kali I use as the basis for my testing which includes a variety of extra tools, preference, references, etc. If you want a copy yourself, you can find one here:
Each version is named for a different character played by Henry Winkler, for the record.
