So what I am basically doing here is to pre-create a rules file on a stand-alone Windows 10 enterprise computer. To do that we first need to generate a wildcard rule that we will later plant on the machine we are attacking, Let me show you in this GIF. These files are used by AppLocker when you execute files to determine if the files should be blocked or not.Īnother way of doing this is to manipulate the files that AppLocker places on disk under c:\windows\system32\applocker. When AppLocker (Application Identity Service) processes the Group Policies it places “AppLocker rule” files in c:\windows\system32\AppLocker. Using a GUI is not always an option especially if you are working through a shell, so here I will go over a different method. Īdding your own rules – with no GUI – (Stealthy as well) Yeah, not ideal – I recommend considering adding this to remove any local rules added. When AppLocker applies the rules it combines the rules defined in the Central Group Policy with the rules defined in the local policy on the host.
So, what you are basically doing here is to add AppLocker rules locally on that host. The GUI way of doing this is to start gpedit.msc on the host itself and adding them like showed in this GIF: If you are a local admin on a host there is nothing stopping you from adding your own rules. The rest of the rules are defined with the default AppLocker rules (* under Windows and * under ProgramFiles). In these bypass technique examples the AppLocker Executable rules defined centrally are as follows (Default rules, without the admin rule): My goal with this post is to document that technique better, but also give you a new technique that has not been showed before, that you need to be aware of. The first technique that uses the GUI was briefly discussed in a tweet I posted a while back: AppLocker cannot enforce rules if this service is not running.I thought it would be useful to have a blog post about two different techniques you can use to bypass AppLocker if you are an admin on a host that has AppLocker enabled. This command is to make sure the Application Identity service is enabled, set to Automatic, and running. Copy and paste the command below into the elevated command prompt, press Enter, and close the elevated command prompt when it has finished. You must be signed in as an administrator to use AppLocker.ĮXAMPLE: "This app has been blocked by your system administrator" message when any user opens a blocked executable (.exe and. com) files to run for all or specific users and groups in Windows 10 Enterprise and Windows 10 Education.
