Collaborate Disseminate
It is a common problem these days. You have a piece of code in C or C++. Maybe it is older code. Or maybe you prefer prototyping your ideas using C. But, inevitably, someone now wants your code to run in a Web browser. The options for making this happen …read more
I am attempting to exploit HEVD kernel driver buffer overflow challenge:

However when running the below code my windows 7 machine doesn’t execute the desired shellcode (assign c… Continue reading Assigning memory address of shellcode to buffer (for buffer overflow input)
So I’m trying to design/make my own encryption algorithm and I believe it to be ok. I’m not saying it’s extra secure but I know it’s not useless so, what I was wondering is if there are any specific tests I can carry out in order to try an… Continue reading Are there any formal tests to estimate encryption strength? [migrated]
out(ECHO_SERV, names.c_str()); displays all of the data in names but on different lines.
The commented out code displays the concatstring iterations, but improperly, like such:
name,
name, name2,
name, name2, name3
name, name2, name3,name4… Continue reading how do i concatstring properly to display names on the same line in a sqlite while loop? [closed]
let say hacker want to come over the aslr or he want to call function that doesn’t exists in user program ,can he insert to the return address address to the share library function or this functions being load only when the user program c… Continue reading is it possible to call libc function with rop
I’m interested in becoming an ethical hacker someday. I’ve been reading articles saying the Python language is very popular in hacking activity because of the extent of its modules (including network).
Nowadays, lots of applications are we… Continue reading Is it important for an ethical hacker to know the C language in-depth nowadays?
Consider the following programme:
#include <stdio.h>
int main()
{
char buf[20];
scanf("%s", buf);
printf("%s", buf);
}
Is it possible to input the Null terminator ‘\0’ (or any other escap… Continue reading Injecting Null-terminator into scanf in C
So I hope I’m phrasing this right. I’m trying to exploit a piece of c code which you can see below.
#include <stdlib.h>
#include <unistd.h>
#include <stdio.h>
#include <string.h>
int user_age;
void secretClub(){

If I compile a code with gets, the compiler outputs a warning saying that the function shouldn’t be used:
<source>:5:13: warning: ‘char* gets(char*)’ is deprecated [-Wdeprecated-declarations]
gets(buf);

In file in… Continue reading Why does my compiler warn me about gets but not about scanf?
I have an excersise of making a buffer flow exploit for directing a function insinde another function without calling it. First I need to print "now inside entrance()" then print "now inside secret()"
I was able to prin… Continue reading How to avoid segmentation fault in a buffer overflow exploit
