API's (How to run an Express GraphQL Server)

-
This example builds off of the other initial GraphQL setup and initialization so I will begin from the end of that article. I already have an Ubuntu virtual machine in the cloud with Node.js & GraphQL. The cloud server initial setup is done at this point. So now, I am going to continue configuring and modifying a few things to turn this virtual machine into an Express GraphQL Server.

 I installed express from the command line with: 


Next I modified the original server.js file I had created. Here I now have a new module which is 'express'.  This will help me to be able to run a webserver and then will mount a GraphQL API server on the HTTP endpoint I have assigned of "/graphql" on my Ubuntu cloud virtual machine.



And now things are beginning to get more interesting. I now have a visual interface with which I can send queries to the API HTTP endpoint. So here when I send a query for '{ hello }' the contents of the variable within my function are returned in GraphQL syntax which works in a very similar manner to JSON. One additional note is that this data exists within an HTTP API endpoint so it can also just be called directly from the URL as:

 http://'theSpecificIP':'thePortNumber'/graphql?query={hello}.

Using the GraphiQL interface to issue queries.

Automated Exploitation of a Bluetooth vulnerability that leads to 0-click code execution

This blog post covers an interesting vulnerability that was just discovered earlier this year and an open source free tool that was created to automate testing for this vulnerability in Bluetooth devices.  I will preface this with the warning that this is of course done in my personal testing lab environment with my own devices for learning and demonstration purposes. I am in no way encouraging that these tools, snippets of code or techniques be used maliciously as there can be very serious legal consequences for those that use these hacking tricks nefariously. However, in a personal testing lab environment I think this is great for learning and allows someone to quickly be able to confirm or deny if their personal devices are truly standing up to the Bluetooth CVE of CVE-2023-45866 . CVE-2023-45866 is described as an issue where the " Bluetooth HID Hosts in BlueZ may permit an unauthenticated Peripheral role HID Device to initiate and establish an encrypted connection, and accept

Raspberry Pi WiFi Honeypot 🍯

This was a fun project to work on and build out. I learned a few new interesting tricks along the way. I started with this tutorial from 2013 by Andy Smith . However, a few things have changed with hostapd that I had to figure out through debugging. Also, the configuration of the nginx server as well as dnsmasq were slightly different for me using the new Raspbian Buster for Raspberry Pi 4.  This should save you some time if you follow my trick tips later on in the article that I found by searching through various message boards and googling error messages as I did debugging to get this working properly. I have gone over setting up nginx servers in previous articles so if you need help with getting started these may be helpful. So first things first. I started with a canakit and assembled the raspberry pi with the appropriate heat sinks and a little fan set to a standard speed. The speed is adjusted by how you install the wiring. If you haven't done this before you can follow the
