Collaborate Disseminate
I’ve been looking more into the techniques behind stack/buffer overflow lately, and after much investigation, found myself learning assembly and writing my own shellcode. It has been a educational experience so far, especiall… Continue reading Why is this shellcode not working? Writing to code/text segment possible culprit?
The Apple II was the popular darling that truly kicked off the ascention of the company that would later bring you darlings such as the iMac, iPod, and iPhone. The brainchild of the legendary Steve Wozniak, it was a low-cost home computer that made use of some interesting compromises to create video output with the bare minimum components. This can make it difficult if you want to output full-bitmap graphics on the Apple II – but it is certainly possible.
[cybernesto] set about completing this task, and released VBMP on GitHub. Programmed in assembly, it builds upon the work of …read more
Background:
First time user of libemu for shellcode detection and emulation, I was only able to find a few and limited resources on the web.
Used a simple loader shellcode to test, and the two instruction (pop ecx and ret)… Continue reading Lib Emu – how to simulate dummy input data/network data
imagine that if i wanted to find a vulnerability in a program that is used by a lot of people in order to exploit it.
the program is open source and is written in C/C++ . would this even be possible (fuzzing excluded) as go… Continue reading is it possible to craft exploits for non-open source C/C++ software without fuzzing?
Surface mount is where the action is in the world of DIY PCBs, and deservedly so. SMDs are so much smaller than through-hole components, and fewer holes to drill make surface-mount PCBs easier to manufacture. Reflow soldering is even a snap now thanks to DIY ovens and solder stencils you can get when you order your boards.
So what’s the point of adding another stencil to the surface-mount process? These component placement stencils are [James Bowman]’s solution for speeding up assembly of boards in production runs too small to justify a pick and place robot. [James] finds that placing small …read more

I was browsing the shell code page in exploit-db website and I have a question, what is the use of these all different shellcode and why should we write them?
Thank you

I know how to use most of the tools in Kali like msfvenom and msfconsole and I can safely call myself a script kiddie.
I learned the basics of C# and that helps me understand some of the things in C, but I still get easily lo… Continue reading I feel like it’s impossible to learn reverse engineering
I am a beginner at buffer overflows been studying this subject from a few days and i found this exercise (code from: here)
I think understand the basic concept i write more than 64 bytes characters and the gets function over… Continue reading Overflowing the buffer yet not jumping to address
Hackaday pages are rife with examples of robots being built with furniture parts. In this example, the tables are turned and robots are the masters of IKEA pieces. We are not silly enough to assume that these robots unfolded the instructions, looked at one another, scratched their CPUs, and began assembling. Of course, the procedure was preordained by the programmers, but the way they mate the pegs into the ends of the cross-members is a very human thing to do. It reminds us of finding a phone charging socket in the dark. This kind of behavior is due to force …read more

I want to learn assembly, but I am not sure what instruction set (if that is correct term?) I should learn?
I have prior experience in programming, and I did a degree in Computer Science but amazingly it was never covered.
