    Right guys first one who completes this errr get the satisfaction of knowing your smarter than the rest of us lol :)

    The object of the exercise is,

    In the document I will give you there is a message I have placed there. Tell me the message and you win... simple isnt it, or not. I have used some form of cryptography to hide it. There are no clues, apart from you're best source of help when you find the message is here: http://www.google.co.uk

    File is located below and contains a mixture of both text and pictures. Now obviously don't pick a random string of words, think more imaginatively ;)

    After the first correct answer is said i'll let you know and you can post guesses in this thread.

    It's a bit crappy put together but i'll make a better one for you when I get time :)

    Nope, its more technical than that.


    Clue:

    For all you coder's out there that have made a keylogger before it should be easy once you've found the encrypted message. What does anyone who codes a 'logger have to know or at least look up if coding it from scratch excluding the language itself ;)

    I think you may get it from that, if not give me a shout and i'll try and give you a better clue as to where the info is in the doc.

    Alright guys i'm going to post the answer to this as no one has got back to me about the answer lol...

    Nearly all of the document is C&P from wikipedia, specifically "the stock market" page. If you look carefully and match up the bits I copied you will know that out of the three pictures on the page, only two came from wikipedia. The last 'graph/chart' I made, this holds the message.

    You might wonder what the message is? Well the clue I gave Xin is the best for this. You will see the completely random numbers down the side of the chart, in no particular order. You may need to zoom the page to see, ctrl+mouse scroll will do fine. A keylogger coder should really know at least some basic info about ASCII numbering. The numbers, starting from the 1st to the last when converted from ASCII to string give you the message "Hello-iexploit-members"

    Clues left in on purpose were, the hyperlinks and the random placement of the picture of which has no significance to anything in the artical. The hyperlinks all relate to wikipedia articles, which should have left you thinking it had been pasted from there.

    It was a slow day in systems analysis when I came up with this so it's not amazing :P
