AppDomainManager Injection

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.

How to use a function pointer in VBA by Akihito Yamashiro

VB6 and VBA come with no support for function pointers.

Also, when you wish to execute a function in a dll using the Declare function, you can only call functions created by the Steadcall calling conversation.

These constraints can be avoided by using the DispCallFunc API. The DispCallFunc is widely used in VB6 when erasing the history of IE. Although the DispCallFunc is known as API for calling the IUnknown interface, in fact, you can also perform other functions other than COM by passing the NULL to the first argument.

As explained in the http://msdn.microsoft.com/en-us/library/ms221473(v=vs.85).aspx , the DispCallFunc argument is as follows.
