hello all...i'm a bit n00b to this but... i wonder if there are docs around showing how to write down shellcodes for win32 systems.... not an advanced docs.. only for the basics.... so that i can start playing a bit with it

if needed also an ASM quickstart guide is wellcome

thnx in advice

http://www.metasploit.com/shellcode.html

might help

This is gonna help very much thnx a lot m8...

i hope it's easy to understand... coz well... i can be compared to a housewife who starts learning this stuff for the first time and i need to learn the basis first of all like how to create my own shellcode with easy examples not necessary usefull for binding shells and so on
for example how to write a shellcode for writing hello world in a dos terminal and so on.... just to understand how to do my own stuff by myself and how to implement it in C code and execute it.... but basically how to bring an asm code and convert it into a shellcode.......

there is also another thing i can't understand.......
why a shellcode is always fragmented into different parts?

for example

Well, If you see it well, the best scode has 16 columns....

Like when you open an archive to edit it (in HEX mode)

Programmers understand better this metod (i think xD)

And its better for debug, and not to make errors in writing in memory/stack.

16/4 --> 4 addresses of MEM.

Sorry for this bad explanation and for my really bad english

ic ic i understhood it all thnx m8.... and about the docs?
^^

Hey,


I am looking for a shellcode for win32, altho my requirement are very specific.
I need a shellcode (bind or reserver) with a size under 241bytes... This is very small, altho if possible, i will have a brand new xploit for you guys


Thanks,
Lemongreen

that's cool.... well
but i dunno how to code it :(else i would have posted it here in a couple of secs

check out www.metasploit.com for the shell code. Not sure about the size but you should find something there. If not www.hack.co.za should have something.
Good Luck.
