VH disassembler . Net is an open source software for Windows, Linux and Mac OS X that can be used to display all internal data structures of any given Visual Studio project. VH disassembler is primarily intended to aid reverse engineering software protection mechanisms that were designed with obfuscation or encryption in mind. Another use might be to analyze the debugging output of the debugging engine of a program, usually under the control of an EDA tool like Microsoft's WinDbg or OllyDbg. VH disassembler is primarily developed by David Southard who also develops several other tools, including !BuildTPI which was used for development on The Pirate Bay trial. In non-technical terms, the difference between a debugger and a disassembler is that a debugger was designed to step by step execute a program binary, with the ability to stop at any instruction and inspect data values. To achieve this, the debugger sets a special hardware flag that is used by the processor to interrupt program execution. A disassembler does not have this ability – it cannot execute program instructions itself. Instead, the disassembler reads raw binary data from an executable file and tries to interpret those bytes as opcodes of some specific processor architecture. In most cases it is only possible to approximate the meaning of those bytes – they might be completely wrong depending on how they have been obfuscated or encrypted. To handle disassemblers, most modern code-signing systems use a technique called 'payload signing' where the code-signing system's private key is used to sign the binary which is then encrypted using another key that is known by the developer or their license server. This way, even the disassembler cannot execute any instructions to retrieve the private key. This is not possible with 'public key signing' where no secret private key needs to be stored. One of the primary goals of VH disassembler is reverse engineering and patching binary files and files protected by commonly used software protection mechanisms like ZIP and RAR. The tool has been used to reverse engineer the PE files from the traffic analysis tool Wireshark, which is used for packet analysis. In 2011 David Hogue used VH disassembler to crack a zip file that was protected with a password that was stored in the header. In 2012, he was contacted by a developer of an anti-virus product who told him about a similar encrypted zip file which had been cracked using the same technique. The developer wanted to know how it had been done and gave him a copy of a decompressed executable file. VH disassembler was used on this binary and all data structures were successfully reconstructed, revealing two secret files in the process. In 2013 David Southard and David Hogue cracked a RAR file using VH disassembler. Original: The first thing disassembler does is to check if the program is protected by a code-signing system. If it is, disassembler tries to decrypt the binary using the public key contained inside of it. This will reveal another binary file with .NET header and containing all of the original program's internal data structures. With this information it is possible to display everything that happens inside of Visual Studio debugger or any other assembly level debugger. cfa1e77820
