ReFrameworker is a general purpose Framework modifier,used to reconstruct framework Runtimes by creating modified versions from the original implementation that was provided by the framework vendor.ReFrameworker performs the required steps of runtime manipulation by tampering with the binaries containing the framework's classes,in order to produce modified binaries that can replace the original ones.
It was developed to experiment with and demonstrate deployment of MCR (Managed Code Rootkits) code into a given framework.
Among its features:
- Performs all the required steps needed for modifying framework binaries (disassemble, code injection, reassemble, precompiled images cleaning, etc.)
- Fast development and deployment of a modified behavior into a given framework
- Auto generated deployers
- Modules: a separation between general purpose "building blocks" that can be injected into any given binary, allowing the users to create small pieces of code that can be later combined to form a specific injection task.
- Can be easily adapted to support multiple frameworks by minimal configuration (currently comes preconfigured for the .NET framework)
- Comes with many "preconfigured" proof-of-concept attacks (implemented as modules) that demonstrate its usage that can be easily extended to perform many other things.
