Let's turn Any .NET Application into an LOL Bin

We can do this by experimenting with .config files.

Many defenders catch/detect files that are renamed, they do this by matching Original Filename to Process Name

In this example, we don't have to rename anything. We simple coerce a trusted signed app to load our Assembly.

We do this by directing the application to read a config file we provide.

Using Hard Links to point back to attacker controlled location.

mklink /h C:\Windows\System32\Tasks\tasks.dll C:\Tools\Tasks.dll
Hardlink created for C:\Windows\System32\Tasks\tasks.dll <<===>> C:\Tools\Tasks.dll

This can redirect the search to an arbitrary location and evade tools that are looking for filemods in a particular location.
