Download Applocker Windows

Another way of doing this is to manipulate the files that AppLocker places on disk under c:\windows\system32\applocker. 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.

Okay, so now we got the rule file, lets go ahead and plant it on a client that is protected (remember, you need to be an admin for this to work). For this to work you also need to reboot the client. I have not found a magic service to stop and start to get it to work without a boot. All you need to do is to copy the Exe.AppLocker file and replace the one in c:\windows\system32\applocker and then reboot.

The sweet thing (for an attacker) about doing it this way is that it does not show up in the GUI on the client, so you must manually inspect the files under c:\windows\system32\applocker to find this.

This can be detected if you monitor changes to the files under c:\windows\system32\applocker. Updates to these files as far as I know is only updated if a group policy changes centrally or if you add your own local rules with gpedit. The timestamps on these files should also be the same. If there are variations it could indicate that someone placed a file there to bypass AppLocker. Another indication can be if one of these files are removed.

The third option fixed the problem but after deleting the files inside Windows\System32\AppLocker and re-run the clear powershell, just to mention that I had this problem in windows 11 (after upgrading from windows 10), Thank you so much for your help.

thanks this worked but i recommend everyone perform every step. i stopped short of the final step of deleting the files in the system32 directory because it looked like windows was behaving again (the fundamental issues were fixed anyway like start menu etc) but a couple days later i tried to run a tool in my PATH in cmd and i got a group policy block alert! so i came back here and did the final step and now everything seems fine

Update2: -us/topic/kb5024351-removal-of-windows-edition-checks-for-applocker-e3a763c9-6a3e-4d9c-8623-0ffe69046470 finally confirms the change. So AppLocker is now supported on Win10 2004 and higher running the October 30, 2022 updates.

Hi I have tried this on mine following a clean install of Windows 11 22h2 and yep applocker is being enforced on pro from gpedit! I have not run any script. I noticed something was odd as I was getting events in event viewer (had always been blank before) when I had not even touched the feature. But yes enforced on mine too (stop no longer work)

so, i have now retest it, make new master image, and see now it works great. i see also now some events in the applocker eventviewer, so now i get a window, applications can not started or so, but it works. maybe WEM Cache or something other have problems

Windows Applocker is a function that was introduced in home windows 7 and windows server 2008 r2 as a method to restrict the usage of unwanted Programs. Windows AppLocker lets administrators control which executable files are denied or allowed to be run. With this policy, administrators are able to generate rules based on file names, publishers or file locations on unique identities of files and specify which users or groups can execute those applications.

Now you'll need to create a parser under $ARCSIGHT_HOME/user/agent/fcp/windowsfg/windows_2008 following the WUC documentation. I've got a basic setup so I'm happy to send that out to you if you need one to get started.

I did the same thing with the registry as you did, where the applocker event log would stop logging. With some help from the Windows team, we were able to tweak it a bit to get it working again. However, we had event forwarding set up to a centralised server (to avoid collecting directly from workstations), and the registry entry didn't work on any events that didn't originate on the server.

The native windows event forwarding is very easy to set up, I'm sure if you work with your Windows team you wont have any trouble. You are also able to filter by Windows event ID at the source workstation, to prevent bandwidth utilisation etc.

We are only interested in applications running that would have otherwise been prevented if the applocker policy were enforced (8003), but I have included both 8002 and 8003 events in the parser file below.

I have created a deny rule in AppLocker and define * in the path and also added Program files & Windows in exception in the deny rule.

now I also want to prevent program files and windows for any unknown type of execcution.

Hi Sandy,

Thank you for writing this article, as this helped me a lot on deploying app locker on win 10. But I found that this only works on win 10 build 1903 & above. On all Windows 10 below 1903 it always generate 8008 error on applocker event log. I use the same ps script as yours to deploy the rule. Is it true that this method only applies to win 10 build 1903 & above? or is there any prerequisite for these builds? e24fc04721
