I'm studying x86 architecture and assembly in order to have the basis for studying reversing and exploit development. I'm following a course on opensecuritytraining.info. I see a Hello World example: push ebp mov ebp, esp push offset aHelloWorld; "Hello world\n" call ds:__imp__printf add esp, 4 mov eax, 1234h pop ebp retn This code was generated by Windows Visual C++ 2005 with buffer overflow protection turned off and disassembled with IDA Pro 4.9 Free Version. I'm trying to understand what each line does. the first line is push ebp. I know ebp stands for base pointer. What is its function? I see that in the second line the value in esp is…

Read/Write ProcessMemory of Private block
by kincses- 18 replies
- 7.4k views
Hi. Making a new thread for this, but is actually a sub-problem coming from my other thread. I'm trying to make a loader (now in c++), which would use the ReadProcessMemory API. The process is created by the loader with CreateProcess(address,NULL,NULL,NULL,FALSE,CREATE_SUSPENDED,NULL,NULL,&startup_info,&process_info) I noticed, that while it reads the memory of an "Imag" memory block, it returns 0x00 (or 0xCC ?) when trying to read from a private memory area. How is this bypassable?

Lets say I have only one tab so then the thumbtrack should take the entire place in the hscroller and if I add more tabs then it should get smaller and smaller etc like in Notepad app for example.Next problem are the positions to set them correctly + calculate the right value to adjust everything you know.I made a example for testing.Maybe you can check this. invoke GetDlgItem,hWnd,IDC_HSCROLL mov…

Hi guys, I have again found a problem and dont know whats the reason for this.I have a PC with a onBoard grafic 1 GB so I told this before on other topic.The problem I have is that I always have any kind of flickering / delay on the screen if I move any window or resize it also with any notepad file it happens.Its more worst if I do it in my Sandbox or also in VM too.Next problem is watching videos so there I always see any not vissible line moving from bottom to top (looks like a scissors cut) especially if there is much moving action in the video.I am really not sure why it is so and whether the onBoard grafic is the problem or not or whether any setting in the BIO…

[C] Wrong strlen of array

Hi, I'm reading about some egg hunter shellcode and noticed a weird thing. If I remove the 'egg tag' in front of my actual payload i'm getting wrong strlen sizes? Why so? The shellcode isn't working in the second example without the egg tag (of course) but this has nothing to do with the strlen function, has it? shellcode1.c (Egg-tag is "Egg-Mark" without "", correct strlen of array) #include <stdio.h> #include <string.h> unsigned char egg[] = { 0x40, 0x81, 0x78, 0xf8, 0x45, 0x67, 0x67, 0x2d, 0x75, 0xf6, 0x81, 0x78, 0xfc, 0x4d, 0x61, 0x72, 0x6b, 0x75, 0xed, 0xff, 0xd0 }; unsigned char payload[] = { 0x45, 0x67, 0x67, 0x2d, 0…
