Hello everyone I have an EXE file packed by ASPACK. I want to write to a memory byte in real-time using asm code "mov byte ptr ds:[xxxxxxxx],xx" but when I do so, I get access violation error. I checked the EXE with some PE editors, code section flags was set to read/write/execute. so this won't gonna help me. what I need to do is, changing memory access in real time by using asm codes or any other way. when I load the EXE in olly and set memory mapping to full access, there will be no access violation error. I'll be pleased if anyone help me. thanks in advence

Writing a program that recurses depends heavily on the stack; Is this a true fact? Example of a program is the legendary Towers of hanoi. //------------ //dexter #include<iostream> //the c++ standard library for stream input output #include<cstdio> //the c standard library for standard input output #include<cstdlib> //for the exit function using namespace std; class arr //arr class that holds each stag { public: int a[100],b[100],c[100]; int topa,topb,topc; }hanoi; int move=1; //counts the no. of moves int main() { void tower(int ,int *,int *,int *,int *,int *,int *); //function prototype void show(int); //function prototype int i; …

HashTable Library for MASM32
by diablo2oo2- 11 replies
- 11.2k views
I was missing a comfortable way to manage complex data structures in MASM. Java coders will know the HashTable class, which is very useful to store data. i coded something similar with more functions for MASM and other programming languages. features: -it will organize memory itself (will use the windows Heap functions) -like in java you can access items via a key which can be a String or an integer -support for nested hashtables (so you can create very easy complex data trees) -save/load the hashtable to disk or memory (with nested hashtables) the example will show how to create following hashtable structure: ; ht_1 ; | ; +-0-->"hello 1" ; +-1-->"hello 2" ; …

NSF player DLL for NES music files. 1 2
by mudlord- 26 replies
- 17.2k views
Here is a DLL I have been working on. I intended this for my keygens and patchers, but figured I make it public. Calling conventions are _cdecl, iirc. Included is a example in C. Basically, this is a Nintendo Entertainment system music playback dll, for NSF/NSFE files.Due to the emulator used, the file size is quite big, but UPX does help somewhat. The emulator emulates all extension chips used for NES audio, including Sunsoft's expansion chips, as well as the VRC6/7 and Namco N-106 chips. EDIT: Also did a SNES SPC-700 emulator DLL. Same parameters as the NSF dll, same calling convention. Uses a much more accurate (cycle-exact) emulator then the dll "SNESAPU.DLL" thats fl…

Making fun with the IT teacher at school...
by mrexodia- 22 replies
- 11.9k views
Hello everyone, I was really bored and had a stupid idea: why not make a program that steals passwords from the users who use it? Before you continue reading you should know that we have about 32 computers at school who all run windows XP and require the user to log-in. The profile data is retrieved from a server and the teacher watches you (not going to sites like failblog.com) with a program called UltraVNC. To continue with this uber-lifeless post: I had the idea to make a program that looks exactly like the windows logon screen which steals passwords by storing them in a mysql database (freemysql.net). The funny thing is that the teacher behind his pc will see a login…

MSVC08 & code optimizing
by deepzero- 3 replies
- 4.4k views
hi, i am writing a function in c++ (msvc2008 pro), which has to be "portable" (ie. no calls to other functions or APIs) and fast. At one point i am using something like while(tlen++ < total) *str++ = leChar;which works fine, but msvc choses to "optimize" it to a crt-memset call. :/ I generally noticed msvc is very keen on replacing code with crt calls to memset, even my custom memset-function, which uses an inlined REPMOV (and serves the sole purpose of making me independant from the crt...). Is there anyway i can turn off this specific optimization feature? I tried all sorts of linker switches; none of which worked properly.

Hello. This is in relation to a patch I'm working on. The description is based on IDA's output. There is a word area in data section called 'Time'. It's used like so: mov eax, Time What I want is a short way to assign a value to 'Time' before the above is executed. The data to use, I can make available through another register. If I try something like: mov Time, ebx it works when I run the program under IDA, but of course fails when run on its own. How can I avoid the relocation problem and do the assignment in as few bytes as possible, say 5? (No more room in the surrounding area). The above is for 32-bit but if you also have a 64-bit way that would be great. Thanks in a…

[Question] Statically linking TitanEngine?
by mrexodia- 1 follower
- 11 replies
- 8.6k views
Hello everyone, I'm currently coding a project that uses TitanEngine, but because of portability issues I want to link everything statically... The problem is that the guide provided here doesn't really work At first I tried compiling the original DLL version, to test if the code was correct. It wasn't (1>.\TitanEngine.rc(10) : fatal error RC1015: cannot open include file 'afxres.h'.) and I "fixed" it by replacing "afxres.h" by "windows.h"... After that another error popped up because the author forgot to do: "#define IDC_STATIC -1". I defined it and the DLL compiles (and runs) without errors... Then I changed the output type to .lib (Static Library), compiled wi…

Hi everyone, Instead of writing IDC script with IDApro, i would like to integrate what IDApro can do into a simple c++ interface using TitanEngine. TitanEngine is a good tool with detailed SDK which can perform disassembling, PE modification, hooking etc. I would like to know how i can retrieve all the addresses of user-defined functions in a C++ .exe program using TitanEngine. If i am to create a dummy c++ file with 3 functions: void func1(), void func2(), void func3(), which API can i use to retireve the 3 functions after disassembling with TitanEngine? IDAPRO has flirt signature and name view which automate the analyzing of all user-defined functions... Is there a byt…
