There’s a designer named Bradán Lane who makes some excellent hardware, and one of my favorite things he’s created is a set of challenge coin circuits. I won’t go into too much detail on them other than to note they have a fun story line, a series of challenges, and you have to exercise some basic hardware hacking skills to participate. If you’d like more details, please check out the listing for the coin on Tindie. But what if you don’t know how to get started? Well, a friend of mine (Visual) and I recently played through this, and thought we’d document how to get started for anyone who needs a little extra help. Let’s get started!Continue reading “Starting the 2020 eChallenge Coin Redux”
So… I got a Proxmark3 RDV 4 for Christmas. It’s great. It’s tiny, svelte, and… had a bunch of errors right out of the box. Naturally that means it’s time to reflash it, but as it turns out the default wiki instructions for Kali Linux aren’t quite right for the RDV 4 now. Let’s fix that, shall we?
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 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 bought a pile of DigiSpark devices on a whim (they’re less than $2 each), and the following are just my notes on how to get things up and running with them to do simple testing. I’ll also note that this was based on the DigiStump connecting tutorial, but I found some gaps in their approach and wanted to document my variations here for posterity.
This is a quick-hit post because as I’ve been working on some hardware hacking efforts I realized that while there are a lot of good resources on identifying JTAG interfaces and standards, there wasn’t really a good single page view of them. With that in mind, I lifted the following images from the excellent resource at http://www.jtagtest.com/pinouts/ and put them into a single page view. Full credit to JTAGtest… I just wanted something I could quickly reference.
