In this post, we will continue to explore driver exploitation, focusing on NULL pointer dereferences, and demonstrating how we can exploit this class of vulnerability on both Windows 7 x64 and Windows 10 x32.... Read More »
Following on from my earlier post [/windows-warbird-privesc/] in which we walked through creating an exploit for the WARBIRD vulnerability, over the next few posts I'm going to be looking at Windows kernel exploitation. If you haven't had chance to read it, I'd recommend that you pause and give it a quick glance as some of this walkthrough will rely on concepts introduced previously. This post will start off by laying the groundwork for future posts, and walking through a simple stack overflow ... Read More »
In this post I wanted to take a look at something which I touched on previously, and that is just how a Windows kernel based exploit achieves privilege escalation. Rather than take something like HackSys Extreme Vulnerable Windows Driver, I wanted to work on something a little bit different... Read More »
For many pentesters, Meterpreter's getsystem command has become the default method of gaining SYSTEM account privileges, but have you ever have wondered just how this works behind the scenes? In this post I will show the details of how this technique works, and explore a couple of methods which are not quite as popular, but may help evade detection on those tricky redteam engagements. Meterpreter's "getsystem" Most of you will have used the getsystem module in Meterpreter before. For those tha... Read More »
Recently I've been trying to make sure that my redteam knowledge is up to date, exploring many of the advancements in Active Directory Kerberos attacks... and there have been quite a few! I finally found some free time this week to roll up my sleeves and dig into the internals of some of these attacks, and hopefully document them for other people to learn. This post is the first in a series aimed at explaining what is happening under the hood when you execute your favourite Powerview or Mimikat... Read More »
