    When using OllyDbg as a portable version (e.g. on an USB stick) there are always problems with the UDD/Plugin path not being set correctly. The features: DLL, which sets Plugins, UDD and win32.hlp paths automatically Dummy export so it's easy to add the DLL to your olly mod Open source Attached is DLL + Source, I hope it's useful for somebody. Feel free to modify to your needs, just credit where you think it's needed. P.S. To add the DLL to your mod: Use CFF explorer to add the import "dummy" (which does nothing) to ollydbg.exe, this will execute the DllMain function (which can be considered illegal) and set the paths in the INI file. OllyPath2.dll must be in the same directory than ollydbg.exe

    This is my 2nd tutorial for BiW-Reversing that will discuss about MUP with ollydbg + ollydump. BTW, my 2nd tute should be about the truth lies behind a keygen. But i need more time to get as much as ideas to discuss about it deeply. For this tute, i just want to unpack UPXed file and as a bonus, FSG 1.33 packed one. I assume the reader has a little knowledge about PE like Entry Point (EP), Original Entry Point (OEP) in packed PE executables. BTW, I want to recommend you to read 'Peering Inside the PE: A Tour of the Win32 Portable Executable File Format' by Matt Pietrek, but other manual/docs about PE also recommended to read (and to learn too).

    This project I made by myself, because I needed to constantly consult the opcodes to several of the assembly codes at the same time, wasting my attention from what I really needed to accomplish. Now with only one opened window I have access to all opcodes that I use when I am working in reversing engineering or developing, I hope it is useful for you. If you have some opcode that you want that I place in this help file, please send the text file. Intel 8086 Family Microsoft .NET Java SQLite

    The default windows API functions to load external libraries into a program (LoadLibrary, LoadLibraryEx) only work with files on the filesystem. It's therefore impossible to load a DLL from memory. But sometimes, you need exactly this functionality (e.g. you don't want to distribute a lot of files or want to make disassembling harder). Common workarounds for this problems are to write the DLL into a temporary file first and import it from there. When the program terminates, the temporary file gets deleted. In this tutorial, I will describe first, how DLL files are structured and will present some code that can be used to load a DLL completely from memory - without storing on the disk first.

    The goal of this project is to create a .NET decompiler. Decompiler is a tool that translates machine code back to source code. That is, it does the opposite of a compiler – it takes the executable file and it tries to recreate the original source code. In general, decompilation can be extremely difficult or even impossible. Therefore this project focuses on something slightly simpler – decompilation of .NET executables. The advantage of .NET executables is that they consist of processor independent bytecode which is easier to decompile then the traditional machine code because the instructions are more high level and the code is less optimized. The .NET executables also preserve a lot of metadata about the code like type information and method names. Note that despite its name, the .NET Framework is unrelated to networking or the Internet and it is basically the equivalent of Java Development Kit. To succeed, the produced decompiler is required to successfully decompile a console implementation of a quick-sort algorithm back to C# source code.

    This article is the obvious culmination of the previous effort of writing the Rebel.NET application and the first of a two series of articles about the .NET framework internals and the protections available for .NET assemblies. The next article will be about .NET native compiling. As the JIT inner workings haven't been analyzed yet, .NET protections are quite naïf nowadays. This situation will rapidly change as soon as the reverse engineering community will focus its attention on this technology. These two articles are aimed to raise the consiousness about the current state of .NET protections and what is possible to achieve but hasn't been done yet. In particular, the current article about .NET code injection represents, let's say, the present, whereas the next one about .NET native compiling represents the future. What I'm presenting in these two articles is new at the time I'm writing it, but I expect it to become obsolete in less than a year. Of course, this is obvious as I'm moving the first steps out from current .NET protections in the direction of better ones. But this article isn't really about protections: exploring the .NET framework internals can be useful for many purposes. So, talking about protections is just a means to an end.

    Decompilation is the process of converting executable binary code ready for execution on a physical or virtual machine into comprehensible high-level language code. Typically compilation has been to the instructions executed by the CPU of the target architecture, e.g. x86, ARM etc. Another possibility is to compile to an intermediate 'virtual machine', which then interprets each instruction one at a time or compiles it to the underlying machine code in a process known a Just In Time compilation (JIT). One of the earliest examples of this is the O-code machine, developed by Martin Richards in the late 1960s to give platform independence to BCPL. The most prevalent example of this sort of virtual machine in existence today is the Java Virtual Machine (JVM), written by Sun Microsystems to execute intermediate code compiled from their Java language. When a program is compiled to the machine instructions of the underlying architecture, it becomes very difficult for someone to understand the code if they only have the binary — this is after all the whole reason compilers exist. Decompilation is the process of converting a binary back to some high-level language, although not necessarily the same language that the code was compiled from. Compilation almost always loses information such as local variable names and explicit identification of control structures. As well as this many compilers perform optimisations which cause the compiled code to bear even less resemblance to the original code. For example, loop unrolling is a technique used to remove the number of branches a program must make.

    Sometimes after you manual unpack a .NET program when you run the program will complain that some dlls are missing, we simply get .NET dlls using a .NET Generic Unpacker (also we could dump the memory of them from Olly) while native dlls are still missing. This tutorial will teach you how to dump native dlls from any .NET packed program. The basic rule: we should stop when the dll is under memory and we should dump the dll before is executed the entry point of him; is not absolutely necessary to stop exactly at entry point of dll.

    As you know, the main purpose of using packers was to decrease the size of executable files, but nowadays most of packers are protectors too! For 32bit packed executables, reversers usually use OllyDbg to unpack them, but OllyDbg is only able to debug 32bit PE files. So what we can do in case of .NET targets? In this short article you'll see how to unpack .NET EXEs in few steps using great OllyDbg. Believe me, it's piece a cake.

    Anti-unpacking tricks can come in different forms, depending on what kind of unpacker they want to attack. The unpacker can be in the form of a memory-dumper, a debugger, an emulator, a code-buffer, or a W-X interceptor. It can be a tool in a virtual machine. There are corresponding tricks for each of these, and they will be discussed separately. - A memory-dumper dumps the process memory of the running process, without regard to the code inside it. - A debugger attaches to the process, allowing single-stepping, or the placing of breakpoints at key locations, in order to stop execution at the right place. The process can then be dumped with more precision than a memory-dumper alone. - An emulator, as used within this paper, is a purely software-based environment, most commonly used by anti-malware software. It places the file to execute inside the environment and watches the execution for particular events of interest. - A code-buffer is similar to, but different from, a debugger. It also attaches to a process, but instead of executing instructions in-place, it copies each instruction into a private buffer and executes it from there. It allows fine- grained control over execution as a result. It is also more transparent than a debugger, and faster than an emulator. - A W-X interceptor uses page-level tricks to watch for write-then-execute sequences. Typically, an executable region is marked as read-only and executable, and everything else is marked as read-only and non-executable (or simply non-present, depending on the hardware capabilities). Then the code is allowed to execute freely. The interceptor intercepts exceptions that are triggered by writes to read-only pages, or execution from non-executable or non-present pages. If the hardware supports it, a read-only page will be replaced by a writable but non-executable page, and the write will be allowed to continue. Otherwise, the single-step exception will be used to allow the write to complete, after which the page will be restored to its non-present state. In either case, the page address is kept in a list. In the event of exceptions triggered by execution of non-executable or non-present pages, the page address is compared to the entries in that list. A match indicates the execution of newly-written code, and is a possible host entrypoint.

    Anti-debugging is the implementation of one or more techniques within computer code that hinders attempts at reverse engineering or debugging a target binary. Within this paper we will present a number of the known methods of anti-debugging in a fashion that is easy to implement for a developer of moderate expertise. We will include source code, whenever possible, with a line by line explanation of how the anti-debugging technique operates. The goal of the paper is to educate development teams on anti-debugging methods and to ease the burden of implementation.

    The Immortal Descendants started out as members of an IRC group on irc.prodigy.net called "Deadmen.Society" way back in 1995. As we gained skills, we realized that there were better, and more productive ways to spend our time. We (TR0YB0Y, Volatility, Raven, Mortis, Yakuza) left the Deadmen.Society and formed a new group, with new principles and theologies under the name "Immortal Descendants". Our goal for this new group, was a collective for friends to learn, and showcase their talent together. Things were good for awhile, but people lost interest, and three of the founding members, Yakuza, Raven And Mortis disappeared. TR0YB0Y and Volatility kept things running for a while, but eventually "REAL LIFE" caught up with them. March 1998, The Immortal Descendants Were No More. ...Seven months later... Volatility signed back online, and regained interest while looking through the old site. What you see now, is a "re-birth" of the Immortal Descendants. We've come a long way since the old lame IRC group days, to become a premiere knowledge group. Update 10-23-2001. Sadly as interest waned, The Immortal Descendants have moved forward onto other endeavors. Treasure this knowledge, expand on it, be inspired to share your knowledge with others.
