Smash The Stack!

Hey guys,

Today I'll show you a cool challenge site, or rather, a real wargame - SmashTheStack (StS). It was keeping me busy the whole yesterday.

StS is all about Linux cracking/reversing/exploit - a skillset that I surely lack. At the moment they are hosting 5 games, 2 of which are active: io and apfel. Each game is a real system all set up for cracking. You start with a shell account with the lowest access level and by cracking/exploiting the insecure linux applications you can gain access to the next level. Kinda cool huh?

At the moment I, rhican, silkut and ch0wch0w are playing the games, but none has reached the top so far. So maybe you should join the race with us ;)

Need any tool to start the game? Here is a list of programs I used: strace, objdump, rec, and of course gdb. Read some articles about them and you'll get everything done.

Smashing the Stack for Fun and Profit by Aleph One is an excellent article to get you started too - I highly believe that the site name originated from that article, but don't quote me on that :P

dude I so did reach the top of io.sts, though they keep adding levels. beach has said he want's to create something like 30 levels there.

and at apfel, i'm pawn4 now, so you have some catching up to do! ;-)
