In this post, we will develop an exploit for the HW driver. I picked this one because I looked for some real-life target to practice on and saw a post by Avast that mentioned vulnerabilities in an old version of this driver (Version 4.8.2 from 2015), that was used as...
Video & additional notes for StreamIO, a medium difficulty Windows machine on HackTheBox that involves manual MSSQL Injection, going from file inclusion to RCE and in this case getting the SeImpersonate privilege back to get SYSTEM via an EFS-based potato.
Video & additional notes for Resourced, an intermediate difficulty Windows machine on PG-Practice that involves password spraying and an RBCD attack.
Acute is a 40-point Active Directory Windows machine on HackTheBox. I'm going to use it to show some techniques which can be useful in other scenarios and keep it short on the things that are not that important.
This part will look at a Use-After-Free vulnerability in HEVD on Windows 11 x64.
In the last post, we looked at a Stack Overflow in HEVD on Windows 11 x64, now are going to continue with a Type Confusion Vulnerability.
After setting up our debugging environment, we will look at HEVD for a few posts before diving into real-world scenarios. HEVD is an awesome, intentionally vulnerable driver by HackSysTeam that allows exploiting a lot of different kernel vulnerability types. I think this one is great to get started because...
In this series about Windows kernel exploitation, we will explore various kernel exploit techniques & targets. This short first part will deal with the VM setup for the rest of the series.
In the last post we explored how to exploit the rainbow2.exe binary from the vulnbins repository using WriteProcessMemory & the "skeleton" method. Now we are going to explore how to use VirtualProtect and instead of setting up the arguments on the stack with dummy values and then replacing them, we...
In this post I will show an example on how to bypass DEP with WriteProcessMemory. This is a bit more complicated than doing it with VirtualProtect but nonetheless an interesting technical challenge. For the target binary I will use rainbow2.exe from my vulnbins repository.
