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.
We are solving Anubis, a 50-point windows machine on HackTheBox which involves an ASP template injection, windows containers, and stealing hashes with Responder. Later we'll escalate privileges using noPAC.
Baby is an easy machine on Vulnlab that involves enumerating LDAP & spraying credentials. For SYSTEM we exploit SeBackup & SeRestore Privileges.
Rainbow is a medium difficulty machine that involves a SEH-based buffer overflow for user and a UAC bypass for root.
