Bitwise rotation with C/C++ and Delphi
by ghandi- 10 replies
- 13.3k views
Hi all, I posted this topic over on ARTeam forum and thought that maybe someone might find this useful here also? If not, disregard this post and forget you ever read it, . I recently tried converting some of my assembler code across to C and Delphi and it required bitwise rotations. Although the C compiler will optimise in rotations, natively they are not accessible that i am aware of. To use them you either have to use intrinsics or inline assembler, the other option is to define macros which use bitwise SHL/SHR and and OR to achieve a psuedo-rotation. I'm not sure whether or not the Delphi 7 compiler will place rotations in, but i know you can use inline assembler or…

A basic way using RtlAdjustPrivilege to detect the debugger (OllyDbg and IDA demo 6.6)As usually but not (enabled by default) for all debugger, the Debugger must acquiring debug privilege to work with its complete capacity. The snippet is simple and probably already used but I write it as simple as possible to get a clear ASM code inside the debugger.RtlAdjustPrivilege: Enables or disables a privilege from the calling thread or process. NTSTATUS RtlAdjustPrivilege ( ULONG Privilege, //[In] Privilege index to change. BOOLEAN Enable, //[In] If TRUE, then enable the privilege otherwise disable.

Hello everybody : ) I am looking for a good guide for learning assembly x86, so that later I could learn reverse engineering. I have a limited knowledge of assembly, and I could solve easy/medium Crackme,I solved several from: HackThisSite and etc.. When I open debuggers/disassembler and trying to solve, I understand that the main part, but there are parts of the margin (less important) that I do not understand, so I want to learn assembly in a "pure" so I know it everything. Can you recommend me a book / website that teaches assembly x86 ?

Hello. I recently started reading about anti debug, found great reference with tons of great ideas, but i cant get one to work. http://anti-reversing.com/Downloads/Anti-Reversing/The_Ultimate_Anti-Reversing_Reference.pdf The one i want to try is "Instruction counting", page 30. Most of them work simply by copying asm code int __declspec(naked) but this oen is different, and i couldnt get it to work this way, and i dont have experience in using structured exceptin handlers. Could someone try to rewrite this small piece of code? Please? Thanks in advance

Issues with TitanEngine StepInto()

As far as I can understand StepInto() function in titanengine steps into a instruction and contains a call back to execute after stepping into has been done. My code doesn't do what I want, wich is basically keep in a vector all instructions it executes until reaching handler_start. void vm::DoNothing(){ } std::vector<std::string> vm::fetch_handler(){ std::vector<std::string> handler; std::string disasm; static uint32_t eip_control = GetContextData(UE_EIP); void* dbg = 0; do { eip_control = GetContextData(UE_EIP); disasm.assign((const char*)Disassemble((LPVOID)eip_control)); handler.push_back(disasm); StepInto(&DoNothing); dump…

Hey guys, This is a small project I did for a friend some time ago, basically it's a DLL you inject into an engima process (by loader, or by inline) and it will put a hardware breakpoint somewhere and write a new HWID. Attached the full source code, you have to manually find the HWID patch offset, but for someone who works with Enigma often this should be no problem...

[Help] Authentication Login in executable

I have a theory in mind but do not know if this is possible today, we assume has a program that requires authentication from an online site (Login) if the User exists and has vip days, the action from behind the executable (form, main) appears after giving the Login form. There are possibilities for type an illusion, bypassing the system making him think that the User has vip (premium) and accept the program (executable)... I hope you understand. Usually people speak it in Fiddler is possible, but I have no idea how. I think normally it checks the type of User that it is in the forum (group), does anyone have any idea how? I'm not asking tutorial, the more you…
