Creating Website Cookies For Return Customers

-
Session cookies are small pieces of data that a website sends out to user's web browsers. They can be used to store stateful information or to record the user's browsing activity. This is usually used by sites to either ensure security by making a user's account information only visible when they are logged in. I can make the cookies and access expire upon logging out. Alternatively, I can use the browsing activity records to do targeted advertisements or offer targeted discounts to customers.

 For this simple cookie I am calling "site_cookie_1" I want to track returning customers. The cookie also has a built in expiry of one day upon which it will in essence self destruct.


Next I wrote in PHP to reflect to the screen whether the user has a cookie or not. Once the cookie is set there is a visual confirmation with the cookie name echoed back to the user. This can also be sent to a text file for logging purposes.


So now when I first visit the cookies.php page I am greeted with a warning that I have not yet had any cookies set on my account.


Now I reload the page and the cookie script runs. Now a cookie is set and the value is reflected to the screen.

And here reviewing the application details I can see that I indeed have a site cookie named site_cookie_1 with the value of return+customer coming from the server which in this case is localhost and it has an expiry date of one day from now.

Return customer cookie is set.

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 🍯

-
Image
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 ...
