Exploit Development - Abusing the Stack

Hello fellow eh.netters :)

I uploaded a new video and write-up to my website the other day to hope to raise the awareness of a how critical a program crash can be.

The video is available both on my website and on Google at http://www.youtube.com/watch?v=tJA4RyAJoU8 and all the files I refer to are included on my website as well as the full write.

On my blog website it can all be found here: http://www.thexero.co.uk/exploit-development/

Hope you enjoy it and hopefully some of you learn something new from this demonstration.

Regards,
TheXero

Re: Exploit Development - Abusing the Stack

Hi n3r,

It wasn't an easy process, but I used this video as a referrance guide http://www.youtube.com/watch?v=9_K4K89QbqM

I originally did it all without metasploit and did everything manually (finding EIP took 4 hours)

My first exploit took a total of 17 days from knowing nothing about it to getting my first exploit reverse shell, so I guess this is like documentation after that initial 17 days of pain back in January 2011 (before I started pwb).

You might find it helpful to also look through the writeup the write-up :)

Awesome, Nullthreat is a really cool guy who certainly knows a lot about Exploit Development, didn't know there was a video, must watch some time too  :)

About my first exploit, that also took a lot of time, but it was fun and the release of endorphins were massive when my exploit finally worked  :)

Anyway, good work TheXero, really cool video  ;)
