WashiI thought it was time to show off some of #AsmResolver's new #native #PE #patching API. In this blog, we discuss how to programmatically inject code into an arbitrary PE, and learn how to construct new import directories as we go.
Injecting Code using Imported Functions into Native PE Files
Patching PE files is easy. Injecting new code that uses functions from external modules, however, is more complicated. In this post, we are implementing a method for rebuilding import directories, such that we can inject any type of code in an arbitrary PE file.
