PowerSploit:

Powerview.ps1 – Queries the Domain Controller and attempts to check if you (current Windows user) have admin privileges on other hosts. If so, we can psexec to get Admin.

Windows Priv-Esc Exploit Suggestor:

Github Repository is linked above but, if you’re lazy, here it is again.

On Windows Host:

systeminfo > systeminfo.txt

Transfer the file back to kali to be run against the python exploit suggester.

On Kali host:


Windows “at” Scheduler:

This command can be used locally to get System privileges since the at system executes commands as system.

Scheduled Tasks:


Unquoted / Trusted Service Paths:

It happens when a developer fails to enclose the file path in quotes if that path has a space. File paths that are properly quoted are treated as absolute and therefore mitigate this vulnerability.

So if we find a file without quotes, like below, it’s vulnerable:

C:\Program Files\Some Folder\1\Service.exe

Windows would try to execute:

C:\Program.exe

C:\Program Files\Some.exe

C:\Program Files\Some Folder\Service.exe

So if we have write access on some target directory we can write a file on that directory:

Check for AlwaysInstallElevated Group Policy Setting:

This setting installs all .msi packages with system privileges for everyone.

/quiet = Suppress any messages to the user during installation
/qn = No GUI
/i = Regular (vs. administrative) installation


Password Spraying:

A loop that iterated over all the users in users.txt and tries all the passwords listed in
pass.txt . Can be used with the net user /domain command listed above for every user in the domain.


Using Procmon.exe to check for “NAME NOT FOUND” dll’s:

Long story short, windows native software and non-native software have updates. There’re updates can render some DLL’s extinct, however, the code that loads such DLL’s handles the exception when the dll is not found rather than a software developer commenting out or removing the dll load code altogether. In such a case, we can use this as a dll hijacking avenue.

  1. Download procmon.exe
  2. execute on Windows machine and set the following filters:

Procmon.exe Dll Hijacking


Check the UPNP Server on Older Machines:


Windows XP and Older:

If you have a GUI with a user that is included in Administrators group you first need to open up cmd.exefor the administrator. If you open up the cmd that is in Accessories it will be opened up as a normal user. And if you rightclick and do Run as Administrator you might need to know the Administrators password. Which you might not know. So instead you open up the cmd from c:\windows\system32\cmd.exe. This will give you a cmd with Administrators rights.

From here we want to become SYSTEM user. To do this we run:

First we check what time it is on the local machine:

Vista and Newer:
