Reader challenge: Obfuscated messages

I'm under the impression that some people are actually reading this blog. So, for the amusement of my readers, here are some little puzzles to be solved.

Send your solutions to windyoona at gmail dot com and I'll post your name or handle under the puzzle(s) you solved!

The challenge is over now. For more problems like this, take a look at Oona's puzzle corner in PoC||GTFO 0x09.

II. Shouldn't be very hard either

III. Might take some effort

  1. Okay, I'm kinda beat for the second one. Other than believing the bit stream to be 180bps on a 1365Hz carrier, I can't seem to decipher anything. Maybe my PLL implementation is screwy or I'm way off track.

    1. I want you know I got a hand cramp doing the second one.

    2. It's not to be taken too seriously!

  2. Hello Oona, I seem to be really bad at this... the first challenge looks like a subtitution cipher, but the language is not English..?

    1. You're nowhere as bad as you think.

  3. Will you be publishing solutions (later in the month)?

  4. Please don't post it directly!

    Some of us need time. :-(

    This is really a great site!

    1. Sure you did... where's your name up there? lol

    2. Any chance we could get a hint on the last one, maybe the last week before your post? (seeing as nobody seems to have figured it out yet)

    3. Good question, I sent my answers in. Oona, did you get my email?

      Delete
    4. No, you'll have to start all over.

  7. Hi Oona,
    Did you get my email with solutions? I've sent the first 2 last weekend... Maybe check the gmail spam folder. Anyway, I've posted a pastebin at http://pastebin.com/zEE6qGRX.

    Thanks

    1. Yes, I got them - I've been a bit busy and not able to respond to emails. I will read them eventually.

  8. That last one is annoying. I keep thinking I've found something, then turns out to be nothing. I bet it's really simple too. -Phil

  9. I had a great time trying to solve these puzzles and I'm sure I'm not the only one holding their breath for the follow-up post explaining the solutions. Don't get me wrong, it's not impatience that making me type this comment, it's lack of oxygen.

  11. In late '90s I stumbled upon a challenge website consisting on some 100 pages which you would have to solve to get to the next. Some had source code hints, others where simple decryption challenges. I was too young at the time to have gotten too far, but if it were still up today and I would find it, I'd do it happily. Thanks for reminding me of that!
