Crack the Sig Challenge.

dlofnep · 03-11-2010 03:38PM #1

Hi guys,

I hope this is ok to post here

I've been running a security challenge in the past few weeks in my sig. I've had quite a few entries - some getting it, some getting half-way. I've released the second challenge today. So far - both have been relatively easy, but I plan to increase the difficulty as they progress. It's a fun and legal way to test yourself.

Also, make sure not to post the answers

Send them privately to myself. I will reveal the results of each challenge after enough time progresses.

Full details here: http://www.depleted.org/~penfold/

All the best,

D.

Great work to everyone who has entered! Have received a huge response. Challenge 3 is up for anyone who hasn't had a crack at it yet.

Silverfish · 04-11-2010 07:19PM

Challenge 3 already?

*gets cracking*

dlofnep · 04-11-2010 07:20PM

Indeedy! I'm sure it won't take you long.

Silverfish · 04-11-2010 07:40PM

I hope that was the right answer. That one was tougher!

dlofnep · 04-11-2010 07:41PM

Indeed it was!

Well done.

fergalr · 04-11-2010 11:31PM

These are good fun; straightforward so far, but I like where this is going.

Fair play to dlofnep

*waits for number 4*

dlofnep · 05-11-2010 03:51PM

Working on challenge 4. I'll stick it up later. I was hoping to add one a week, but you're all getting them so quickly - it's nearly turning into one a day

dlofnep · 05-11-2010 06:00PM

Ok.. Challenge 4 is up

It should be a little more difficult than the previous challenges, and a bit more fun too! Best of luck. If I can offer one hint, it's that 2 of the symbols look similar, but are not the same symbol! So be careful.

BaconZombie · 05-11-2010 06:31PM

Crap, heading to the Dublin 2600 meeting now so this will have to wait till tomorrow { or when I've drunk later tonight.}

typo? the second correct mark should be a snowflake shouldnt it ? PM on its way.

dlofnep · 05-11-2010 07:26PM

Yes - LoLth pointed out a typo in the letter. I have corrected it, and the updated version is now on the site.

Congrats btw LoLth

Very quick on the draw!

Redshift · 05-11-2010 07:46PM

Damn typo had me scratching my head , PM on the way. Enjoyed that

dlofnep · 05-11-2010 07:57PM

Well done

Good work. You guys are getting these quicker than I expected. Will need to up the difficult a bit more for the next one. Won't be for a few days though.

Jumpy · 05-11-2010 08:32PM

2,3 and 4 done.

Jumpy · 05-11-2010 08:33PM

I think I have the first one, but is it supposed to make sense?

It is if you have it - If you don't, it won't

dlofnep · 06-11-2010 09:21AM

For all those who have asked - Challenge 4 is not a pre-made font. It is custom.

dlofnep · 06-11-2010 01:01PM

Site freshened up a little bit, and I've added a bit more context to each of the challenges. I'll try to get up challenge 5 today or tomorrow. I have a really good idea

It's just a matter of implementing it.

Edit: Challenge 5 up

Eh ... is it

dlofnep · 06-11-2010 05:03PM

Sorry I took it back down for a few hours. There was a hint in the file-name, so I'm re-doing it and I'll upload it when I get home from work.

And there I was looking for something obliquely hidden in the source of the HTML...

dlofnep · 06-11-2010 05:10PM

LOL - I would have probably done the same

I'll upload it in about half an hour. Finished work at 4:30

Me too ... took all the pages down locally and was poring through the source :cool:

dlofnep · 06-11-2010 05:23PM

I was considering doing some SQL injection & javascript stuff - But I think the hassle of it all isn't worth it, as it's not my server or database - it's just a wee shell I have on a friend's box. I think I'll just stick specifically to cipher challenges, unless otherwise stated

dlofnep · 06-11-2010 06:03PM

Ok - challenge updated

dlofnep · 06-11-2010 06:19PM

Well done again Redshift. On the money as usual.
