Listed in categories: .NET Code Injection Tools, .NET Executable Editors

Most recent version:
1.3.0.1

Most recent release date:
February 19, 2009

Description:
Rebel.NET is a rebuilding tool for .NET assemblies which is capable of adding and replacing methods and streams.

It's possible to replace only a limited number of methods or every method contained in a .NET assembly. The simplicity of Rebel.NET consists in the replacing process: one can choose what to replace. For instance, one may choose to replace only the method code, instead of its signature or method header.

The interface of Rebel.NET is quite a simple one. As input it requires a .NET assembly to be rebuilded and a Rebel.NET rebuilding file. The Rebel.NET file contains the data that has to be replaced in the original assembly.

Rebel.NET can also create a Rebel.NET file from a given assembly. This is a key functionality, since some times the data of the original assembly has to be processed first to produce a Rebel.NET file for the rebuilding of the assembly. This sort of "report" feature can also be used to analyze the methods of an assembly, since reading the original data from a .NET assembly isn't as easy as reading a Rebel.NET file. It's possible to choose what should be contained in the Rebel.NET file.

All the Rebel.NET features can used through command line, which comes very handy when an automated rebuilding process is needed.

Rebel.NET is, mainly, a very solid base to overcome every .NET protection and to re-create a fully decompilable .NET assembly. As such, Rebel.NET has to be considered a research project, not an encouragement to violate licensing terms.

Tool Added: NetAsm

Listed in categories: .NET Code Injection Tools

Most recent version:
1.0

Most recent release date:
July 25, 2008

Description:
NetAsm provides a hook to the .NET JIT compiler and enables to inject your own native code in replacement of the default CLR JIT compilation. With this library, it is possible, at runtime, to inject x86 assembler code in CLR methods with the speed of a pure CLR method call and without the cost of Interop/PInvoke calls.

NetAsm can be used to integrate optimized native code using CPU extended instructions (SSE,MMX) into your managed code. The NetAsmDemo sample provides two benchmarks that unveil the power of using native code injection with NetAsm.

For more information about NetAsm, code injection techniques and recommendations, please consult the NetAsm-UserGuide.

Tool Updated: .NET Hook Library

2008-01-26T14:23:32Z

Listed in categories: .NET Code Injection Tools, Code Injection Tools

Most recent version:
2.1

Most recent release date:
May 30, 2002

Description:
.Net Hook Library is a library (with a sample tool) to manipulate functions in a .NET Assembly. It allows for insertion of arbitrary code at the beginning of each function called in a .NET assembly (whether executable or assembly). Also provides code that reads through metadata and dumps information on it.

The download contains detailed documentation about how it works and what it is.

I'm in the process of converting this from an executable to a library. That way, existing applications can use it to modify the .NET binaries (a.k.a assemblies).
