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
- 7.4k 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…

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…
