Writing Beacon Object Files Without DFR
Beacon Object Files have become very popular for red teams to add additional capabilities on the fly without needing to include the overhead of a reflective DLL or .NET assembly. This advantage comes at the cost of Beacon Object Files being a little bit awkward to develop. One development quirk is the need to prefix imported symbols with the associated library name where the symbol can be found. This concept, known as Dynamic Function Resolution (or DFR), is how the BOF tells the BOF loader where to find external symbols.
What if I told you that you do not need to write these DFR prototypes in your code when developing BOFs? Writing Beacon Object Files Without DFR
