The files got removed immediately after being created but I managed to capture them and the only content that was in them the was the number one: 1 Troubleshooting this a little bit more I noticed that they are not signed and since they are located in "AppdataLocalTemp" we did not want to allow them by path (since the user have writing rights in that folder). The script itself ran as expected but the 2 PSScriptPolicyTest scripts was blocked in the log at the same time. In my case I had a PowerShell logon script that was signed and allowed in AppLocker. The full name is something like _PSScriptPolicyTest_1 where the name is _PSScriptPolicyTest_.ps1/psm1 Checking the event viewer log for AppLocker events you will see that the logged on user tried to run 2 different scripts starting with _PSScriptPolicyTest and the extensions. If you are using AppLocker (which you should) and have enabled the function "MSI and Scripts" in AppLocker to whitelist only signed PowerShell scripts you will get some errors in the event log even though your scripts are signed. Htt ps:///7/applocker-and-powershell-how-do-they-tightly-work-together/ Found another good article discussing the topic further:.The filehash is not reported in the eventlog for these event for me anymore (might just be my labsetup that is incorrect though)."# PowerShell test file to determine AppLocker lockdown mode " The content of the ps1,psm1 file is no longer "1" but rather.It seems there have been some changes in how these files are used by Windows sometime since I wrote the original post and now. This also means that the hash no longer is static and cannot be excluded by mistake (which is good since you shouldn't have done that in the first place). "# PowerShell test file to determine AppLocker lockdown mode 15:15:08".Or, for a filter or search, you could also do something like Any Event (or Alert).ProviderSID = Microsoft-Windows-AppLocker* to see all events from AppLocker.As noted by user bbk in the comments, in recent versions of Windows 10 the script no longer have a static content but rather a dynamic one where part of the content includes date and time. In a filter or rule you could OR them together to see all of them. Correlation/filter/search criteria: ProcessWarning.ProviderSID = Microsoft-Windows-AppLocker 8004.Correlation/filter/search criteria: ServiceWarning.ProviderSID = Microsoft-Windows-AppLocker 8003.Correlation/filter/search criteria: ProcessInfo.ProviderSID = Microsoft-Windows-AppLocker 8002.So, for the 3 you identified, you could build a rule for each, or one rule for all of them. There are some other detailed fields like WarningMessage that include more detailed reasons on some of these. "(application) was not allowed to run.".ProviderSID "Microsoft-Windows-AppLocker 8007".ProviderSID "Microsoft-Windows-AppLocker 8005"."(application) was prevented from running.".ProviderSID "Microsoft-Windows-AppLocker 8004"."(application) was allowed to run but would have been prevented from running if the AppLocker policy were enforced.".ProviderSID "Microsoft-Windows-AppLocker 8003".ProviderSID "Microsoft-Windows-AppLocker 8002".EventInfo: "The AppLocker policy was applied successfully to this computer".ProviderSID: "Microsoft-Windows-AppLocker 8001".Looking at the connector, those events will be: Any Event.ProviderSID = *8003* OR Any Event.ProviderSID = *8004* OR Any Event.ProviderSID = *8002* - Any Event might be called Any Alert but same thing). Of course, it'll only trigger when the event does (e.g. In its simplest you might build a filter or use nDepth to search for anything with ProviderSID containing any of those numbers. Applied only when the Enforce rules enforcement mode is set either directly or indirectly through Group Policy inheritance. dll file would be blocked if the Enforce rulesenforcement mode were enabled.Īccess to is restricted by the administrator. was allowed to run but would have been prevented from running if the AppLocker policy were enforced.Īpplied only when the Audit only enforcement mode is enabled.
