Mono.Cecil Patch
by high6- 2 replies
- 16k views
Open "Mono.Cecil.Cil/CodeWriter.cs" Find "ComputeMaxStack" Add this line above it "if (!CodeWriter.FixedMaxStack)" Add field to the CodeWriter class "public static bool FixedMaxStack = false;" CodeWriter.FixedMaxStack = true; Reason for this patch is because otherwise Cecil will attempt to recompute the MaxStacks. It does not work on obfuscated code. For example ldc_i4 0 ldc_i4 0 ldc_i4 0 ldc_i4 0 br lb2 lb1: ret lb2: ldc_i4 0 ldc_i4 0 ldc_i4 0 ldc_i4 0 br lb1Cecil will compute it as 5 when it really is 8. Causing a stack overflow (InvalidProgramException) when it runs.

ASP.NET: ASM to IL compiler
by sirp- 1 reply

Lately we have been swamped with Bill Gate's new .NET vision. Once again even respectable people are crying out that C++ and assembler programmers will become extinct dinosaurs. My reaction to that is: "It's not fair!" Why are they always picking on assembler programmers? We don't do a lot of harm! Just because we like to have total freedom and like to be close to our hardware doesn't make us bad people. Go pick on someone else (like LISP programmers. I don't like them). Frankly, I was getting a little tired of this whole discussion, so I decided to do something about it - by bringing x86 assembler programming into the .NET age. Well, at least to allow ASP.NET pages to be…

BlackMagic -- Managed Memory Manipulation This is a class library to make process, thread, and memory manipulation a bit easier from a managed application. It takes care of most of the Win32 imports and a lot of the methods and tricks for you, making memory reading, writing, injection, execution, and DLL injection a snap, among a bit else. It uses ManagedFasm for JIT assembly, as well. Take a look through the code, the included examble, and the documentation. Most everything should be pretty easy and intuitive to use. If you have any questions, comments, or suggestions, please do not hesitate to post. Attached are the source, the documetation, and the binary class library…

Hooking to defeat hardware breakpoints
by FlySky- 3 replies
- 7.7k views
Hey guys, New to the forum and wondering the following. Been doing reversing for a while now and recently jumped into unpacking. What I am facing atm is that a lot of packers are detecting hardware breakpoints. I am currently on Windows 7 64 bit version and none of the Ollydbg plugins are working for me, so I started looking in writing my own hooks. Been programming / coding for a couple of years in assembly and I am hoping you guys could push me in the right direction about hooking to prevent hardware breakpoint detection. The hardware breakpoint detection is accessed and controlled from an exception handler. So I read up about it and found out an area to hook could be h…

HWID Protection System

Been learning to code on this few months and saw some pay2cheat websites using HWID protection system. I was wondering how did they code these. I'm trying to learn on how the HWID system is coded. Any source to review with? Been googling for few hours and return with no result, most of the HWID protection system found on google were using Visual Basic instead of Visual C++. A source for an example would be great. Questions 1. How to generate the unique ID for every computers? 2. How did they host the HWID on the internet?

Well i have been coding in assembler from the very first day i started in the scene. but now i am really getting mad with this situation... I was reversing a software (my ideas here are doing a keymaker and cracked dll here). basicall this thing uses cryptopp - yeah big pain in the ***. what it does is ECDSAsignatureberify("OCDE"+username,signature).the signature is your serial number. i know this seems easy... that was what i thought too. but when i looked at it closer... omg the cryptopp libs are a total NIGHTMARE there are not any clear manuals anywhere where i really can know how this works. the signature produced by cryptopp for ecdsa is an array of bytes - how can t…
