Hello all,

At Insomni'Hack 2011, we created a challenge dedicated to static reversing of Symbian executables (using SDK S60 Ed3 FP1). Sadly, nobody found the full solution, so we finally decided to put it online for you to try, until November 1st, 2011. We will then post the winner's solution on this blog, along with the 'official' solution. To help you out - if needed - this post will be updated with a hint in a few days.

Challenge prize? the winner (first good solution) receives ... fame and glory :)) i.e. nothing besides marketing goodies, if desired :D

Challenge steps:

  • retrieve the archive here

    sha256 => B74D50104499C35EE9544A77A0DD491646991CD2B3780A7571377152A5F65BD0 P@55 => *Dneige

No username. 7z archive contains an IDA disassembly, an executable, some snapshots and a readme

  • find the secret sentence

  • send us an e-mail at FORTIChallenge@fortinet.com with the secret sentence and explain the solution you used.

That's all for today, happy RE !
