Boflink: A Linker For Beacon Object Files
Intro This is a blog post written for a project I recently released. The source code for it can be found here on Github. Background The design of Cobalt Strike’s Beacon Object Files is rather unique when compared to other runtime code execution implementations. These are small programs compiled into COFF object files which are loaded and executed by a COFF loader. Another addition that Beacon Object Files make is the concept of dynamic function resolution or DFR which allows the COFF to invoke functions from external DLLs.
