Tool name: Rebel.NET
Rating: 5.0 (1 vote)
Author: Daniel Pistelli                        
Website: http://ntcore.com/rebelnet.php
Current version: 1.0.0.1
Last updated: April 25, 2008
Direct D/L link: http://ntcore.com/Files/RebelDotNET.zip
License type: Free
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.

License type: Freeware
Description: The CFF Explorer was designed to make PE editing as easy as possible, but without losing sight on the portable executable's internal structure. This application includes a series of tools which might help not only reverse engineers but also programmers. It offers a multi-file environment and a switchable interface.

Also, it's the first PE editor with full support for the .NET file format. With this tool you can easily edit metadata's fields and flags. If you're programming something that has to do with .NET metadata, you will need this tool. The resource viewer supports .NET image formats like icons, bitmaps, pngs. You'll be able to analyze .NET files without having to install the .NET framework, this tool has its own functions to access the .NET format.

Also includes a cool new scripting engine!

Description: This is a program to dump .NET packed applications. Of course no serious .NET protection relies on packing. In fact, this software shows how easily you can unpack a protected assemly. This .NET Generic Unpacker was written in a couple of hours and despite of the fact that it's very simple, it might turn useful having it: otherwise you have to unpack manually, which is also very easy.

License type: Free / Open Source
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).

Tool name: PEBrowse Professional
Rating: 0.0 (0 votes)
Author: SmidgeonSoft                        
Website: http://www.smidgeonsoft.prohosting.com/pebrowse-pro-file-viewer.html
Current version: 9.2.5
Last updated: 28 December, 2007
Direct D/L link: http://www.smidgeonsoft.com/download/PEBrowse.zip
License type: Free
Description: PEBrowse Professional is a static-analysis tool and disassembler for Win32/Win64 executables and Microsoft .NET assemblies produced according to the Portable Executable specifications published by Microsoft. For Microsoft Windows Vista, Windows XP, Windows 2000, and others. (We have received reports that the software also works on other OSes, including Wine (!) and Windows CE.)

With the PEBrowse disassembler, one can open and examine any executable without the need to have it loaded as part of an active process with a debugger. Applications, system DLLs, device-drivers and Microsoft .NET assemblies are all candidates for offline analysis using PEBrowse. The information is organized in a convenient treeview index with the major divisions of the PE file displayed as nodes. In most cases selecting nodes will enable context-sensitive multiple view menu options, including binary dump, section detail, disassembly and structure options as well as displaying sub-items, such as optional header directory entries or exported functions, that can be found as part of a PE file unit. Several table displays, hex/ASCII equivalents, window messages and error codes, as well as a calculator and scratchpads are accessible from the main menu.

While the binary dump display offers various display options, e.g., BYTE, WORD, or DWORD alignment, the greatest value of PEBrowse comes when one disassembles an entry-point. An entry-point in PEBrowse is defined as:

* Module entry-point
* Exports (if any)
* Debug-symbols (if a valid PDB, i.e., program database file, is present)
* Imported API references
* Relocation addresses
* Internal functions/subroutines
* Any valid address inside of the module

Selecting and disassembling any number of these entry-points produces a versatile display rich in detail including upper/lowercase display, C/Pascal/Assembler suffix/prefixing, object code, color-coded statements, register usage highlighting, and jump/call target preview popups. Additional information, such as variable and function names, will also be present if one has access to a valid PDB file. Disassembly comes in two flavors: linear sweep (sequential disassembly from a starting address) and recursive traversal, aka, analysis mode (disassembly of all statements reachable by non-call statements - extended analysis disassembles all internal call statements as well). The latter mode also presents local variables with cross-referencing, highlighting, and renaming options. If one adds/changes variable name or adds comments to specific lines, these can be displayed in a session file which will record and save all currently opened displays.

PEBrowse Professional will decompile type library information either embedded inside of the binary as the resource "TYPELIB" or inside of individual type libraries, i.e., .TLB or .OLB files.

PEBrowse Professional also displays all metadata for .NET assemblies and displays IL (Intermediate Language) for .NET methods. It seamlessly handles mixed assemblies, i.e., those that contain both native and managed code.

Finally, PEBrowse can be employed as a file browse utility for any type of file with the restriction that the file must be small enough that it can be memory-mapped.

Current version: 5.0.50.0 (with autoupdate feature)
Last updated: Frequently

License type: Free
Description: From website:

"Reflector is a very powerful class browser, explorer, analyzer and documentation viewer for .NET. Reflector allows to easily view, navigate, search, decompile and analyze .NET assemblies in C#, Visual Basic and IL."


This is one of the most powerful .NET decompilers that you can't buy - just download :)
Many of the popular commercial tools achieving the same goal "suddenly" got a boost when this masterpiece of work saw a daylights (and besides that those are commercial, still have hard time with obfuscators).

Just give it a try, it will last literally five minutes - load some well known assembly of yours, choose target .NET language (!) and let'em work. Then compare it with the original.

You'll surely not forget this one.
