And with Microsoft making technologies like Virtualization Based Security (VBS) and Hypervisor Code Integrity (HVCI) available, I wanted to take some time to understand just how vulnerable endpoints are when faced with an attacker set on escaping to Ring-0....

Recently I've been looking at the .NET CLR internals and wanted to understand what further techniques may be available for executing unmanaged code from the managed runtime. This post contains a snipped of some of the weird techniques that I found.... Read More »
In this post, we are going to look at the Application Proxy protocol, how it works, and show how we can recreate enough functionality to allow us to create a custom inbound proxy into a client environment for our C2 traffic.... Read More »
