After a little hunting, I found Digoo DG HOSA 433MHz 2G&GSM&WIFI Smart Home Security Alarm System Protective Shell Alert with APP which looked interesting so picked one up to tear apart. I was curious about how various communication methods were implemented. This is the first part of this adventure the next part will be exploring the firmware of the device.

Hashcat in AWS EC2
· β˜• 8 min read · ✍️ suidroot
Intro During my OSCP studies, I realized I needed a more efficient system for cracking password hashes. The screaming CPU fans and high CPU usage became a problem. I first tried using hashcat and the GPU on my MacBook Pro in OS X. There are some bugs and problems with hashcat on OS X that would make it crash in the middle of cracking a hash. Also, I was not interested in investing a server with a bunch of GPUs, the high costs to do this would outweigh the amount of time I need the system.

· β˜• 5 min read · ✍️ suidroot
I needed to set up and Meraki API key to test, well an Meraki API that was in beta. This is the process I used to get started with some of the basics of the Meraki API and getting a test environment up and running. There are lots of great references covering the basics of REST APIs like the REST API Tutorial. These resources will do a much better job then I can of explaining REST APIs.

Small Projects: Temperature, Humidity and Light Sensor
· β˜• 1 min read · ✍️ suidroot
This post is some free-ish form notes about a project that is either work in progress or complete. Description This project is a small sensor to monitor Temperature, Humidity, and Light levels. The project may end up in a toy Star Trek TNG Tricorder case at some point in the future, but I wanted to document where it is at a today. Originally I used an Adafruit Huzzah (ESP12) board, but after I determined I wasn’t going to use the wifi, I switched to the Adafruit Adalogger board.
