Reverse SSH shell to WSL2 WLS2 is configured by default in a NAT network.That means we can't generally reach it from the outside.  To connect to it externally, let us configure WSL 2 for reverse shell Prerequisite Another SSH server that acts as gateway. This server should be accessible from the outside. For this exercise we will be using 192.168.2.30 as the gateway IP. Step 1: Enable SSH on WSL2 $: sudo ssh-keygen -A Then start SSH: $: sudo service ssh start Step 2: Verify connection from WSL2 to the gateway SSH server $: ssh -R 2222:localhost:22 u1@192.168.2.30 Below is an example connection to Kali SSH server From Kali gateway server, verify that we can connect to port 2222, like: $: ssh u2@localhost -p 2222 By default WSL2 does not allow SSH connection using password, you will get an error like below. u2@localhost: Permission denied (publickey). To fix this, change /etc/ssh/sshd_config on WSL2, ensure that:  PasswordAuthentication is set to yes ChallengeRespo

This is closely related to debugging COM server using CDB/WinDbg combination .  Debugging startup or registration of out of process COM server can be tricky as the process is being started by the COM infrastructure (RpcSs). To debug a COM server called myserver.exe, do run the following: c:\> reg.exe ADD "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\myserver.exe" /v debugger /t REG_SZ /d "vsjitdebugger.exe" /f The next time myserver.exe is activated the Visual Studio debugger will popup and provide an option to run a new instance or attach to an existing session. Note that same technique applies to Windows service.

The Assembly Binding Log Viewer(fuslogvw.exe) displays details for assembly binds. This information helps you diagnose why the .NET Framework cannot locate an assembly at run time. These failures are usually the result of an assembly deployed to the wrong location, a native image that is no longer valid, or a mismatch in version numbers or cultures.  If you don't have Visual Studio installed and you wanted to run it (fuslogvw.exe), do: Download Windows 10 SDK installer .  Install Windows 10 SDK and ensure Open fuslogvw.exe in C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.8 Tools
