How to make the shellcode work. The stack is not correctly allocated, it gives a write-by-address error. I use msvc compiler. /Od /DYNAMICBASE:NO /MT /GS-.
Code:
#pragma code_seg(".text")
inline void stub()
{

I am developing a custom shellcode encoder in C++. It takes shellcode as a command line argument and generates encoded shellcode (unsigned char array) and the instructions to decode it (C/C++ code). I then use the output of my encoder into… Continue reading Decoding shellcode gets detected in memory on runtime

[Mike Engelhardt] is a name that should be very familiar to the hardcore electronics nerd. [Mike] is the developer responsible for LTSpice, which is quite likely the most widely used …read more Continue reading QSPICE Picks Up Where LTSpice Left Us
I’ve read that there are unsafe functions that we should try to avoid when writing C/C++ programs for example the gets() or strlen() functions.
Let’s say I compile a .cpp/.c file into an object file and then I run the following command (su… Continue reading Does the presence of an "unsafe" function in an object file pose a security risk
Database admins strive to ensure that large chunks of data are both accessible and stored with integrity. By using these programming languages, they can keep systems optimized. Continue reading 5 programming languages database administrators should learn
I have started with the book ‘Hacking: The art of exploitation!’. I know some of you might suggest that it’s pretty old… But I think great buildings withstand due to their strong foundational base. So, I have to get into what happened ba… Continue reading How do I prevent the random alignment of the instructions during debugging using gdb? Even tried turning off the optimization with -O0 in gcc

HP calculators, slide rules, and Forth all have something in common: reverse polish notation or RPN. Admittedly, slide rules don’t really have RPN, but you work problems on them the …read more Continue reading In Praise of RPN (with Python or C)
So I try to understand stack based buffer-overflow but now I am stuck. This is the vulnerable function (32 bit ELF).
int test(char* input)
{
char buf[100];
printf("Buffer is at %p\n", &buf); // leak helper
strcpy(… Continue reading bufferoverflow chars gets replaced on stack [closed]
