It’s pretty much my first time playing around with a buffer overflow exploit. I’ve written a simple C program that is vulnerable to buffer overflows:
#include <stdio.h>
#include <stdlib.h>
#include <string.h&g… Continue reading What lies behind this complicated shellcode on linux?
I am trying to exploit the vulnerability in the following program by causing a buffer overflow:
#include <stdio.h>
#include <string.h>
int main (int argc, char ** argv){
char message[20];
Good evening,
I’m trying to exploit the application as indicated at https://www.exploit-db.com/exploits/39939/. I run the application in a vm:
Linux ubuntu 3.13.0-100-generic #147~precise1-Ubuntu SMP Wed Oct 19 00:07:19 UTC … Continue reading iSQL 1.0 – isql_main.c Buffer Overflow
I have written a shellcode to unlink a file from the system, but when I extracted the hexcode off the binary file, it consists of \x0a byte, because the sys call number for unlink function is 10, so it is essentially being treated as new l… Continue reading Eliminating 0x0a from ShellCode for unlink file
The demoscene is a hotbed of masterful assembly programming, particularly when it comes to platforms long forgotten by the passage of technology and time. There’s a certain thrill to be had in wringing every last drop of performance out of old silicon, particularly if it’s in a less popular machine. It’s that mindset that created Don’t Mess With Texas – a glorious megademo running on the TI-99/4A.
Entered in the oldskool demo contest at Syncrony 2017, the demo took out the win for [DESiRE], a group primarily known for demos on the Amiga – a far more popular platform in …read more

I am practicing exploit development and trying to remake this exploit by myself in the same environment:

Can we prevent unauthorised access of assemblies using windows user login in .Net framework ? I have heard that using .Net Runtime security model we can achieve it. Is it possible and how ?

We’re used to reflow soldering of our PCBs at the hacker level, for quite a few years people have been reflowing with toaster ovens, skillets, and similar pieces of domestic equipment and equipping them with temperature controllers and timers. We take one or two boards, screen print a layer of solder paste on the pads by using a stencil, and place our surface-mount components with a pair of tweezers before putting them in the oven. It’s a process that requires care and attention, but it’s fairly straightforward once mastered and we can create small runs of high quality boards.
But …read more
I need to produce a presentation on buffer overflows for a college class. I managed to create a simple buffer overflow where i inject the address of a specific function on the EIP and the function gets executed as expected.
… Continue reading Shellcode doesn’t execute despite correct address on EIP
[Bisqwit] has feelings about games that use exclamation points in his idiosyncratic walkthrough of all the nuances of the passwords in the famous Punch Out Bang Bang.
As he states in his deeply weird (though in no way wrong) channel intro, when he’s not driving a bus or teaching Israeli dance, he works hard to understand the things around him. Naturally, a mysterious phone number shaped set of digits in a favorite game was a secret worth extracting.
The digits can represent every possible state in the game. It uses a pretty simple decoding and encoding scheme, which he walks …read more
