Another Hint: Think alphabetical.

It was posted on another forum and after several days we aint got a clue.
someone seemed to think it was something to do with binary.

Dunno if this helps … the first few things of the hint are the number keys without a shift. The whole string is: 12343578=6|`/8.4+15+2/=8.4+{/=]8|9/2~

Not sure if that helps. On the other hand, to continue the binary thought, take a look at this binary and ascii table http://www.prepressure.com/library/binhex.htm
to see if there is a pattern to it. I couldn’t find one. Is there a known solution?

What’s the context of the riddle, was it just given to you as that text string, or is there a little story around it?

Also, is it meant to be read as a single line, or spilt into lines as you’ve done here?

I thought it might be Base64 encoded (it does resemble it strongly), but according to this page, it isn’t.

OK, I threw the whoel thing into Notepad, and adjusted the page width until the MQ0K terms lined up vertically.

This gives:

MTEwMTExMDAxMDExMTAxMTExMDExMTEwMDAxMTAwMTAxMTAwMTEwMTAxMDEwMTAwMDExMDEwMTExMDAxMTAwMTExMTEwMTAxMTEwMTExMQ0K

MDAxMDAxMTEwMTEwMTExMTEwMDEwMDAxMDAxMTAwMTAwMTExMTAxMDAwMTAxMDAxMDAxMTExMDEwMTAxMDExMTEwMDAxMTAwMTExMDAwMQ

[Sorry about eating up the page width size]

Chucking that through QED’s base 64 decoder gives:

1101110010111011110111100011001011001101010101000110101110011001111101011101111

If someone can decipher the binary, I would be interested in seeing how it turns out, but I’m placing my bets with the accompanying clues.

Oooooooo…good job there. I hadn’t thought to adjust the alignment. Unfortunately according to this page that binary string decodes to:

If you substitute the four letter groups with numbers:

MDAw = 1
MDAx = 2
MDEw = 3
MDEx = 4
MTAw = 5
MTAx = 6
MTEw = 7
MTEx = 8

You get the following pattern:

78246847256576354382587678
MQ0K
82858278687684716838813253
MA0K
84476473647322558426361754
MA0K
22778732255861622836472581
MQ

Four groups of 26, each followed by an anomolous four letter group. The twenty-six group strings along with the second hint suggest there’s four substitutions for the alphabet.

That’s what I get for posting without proofreading. Obviously the last 26 character string isn’t followed by a four character group. If we split the anomolous groups, we get the following:

78246847256576354382587678MQ
0K82858278687684716838813253MA
0K84476473647322558426361754MA
0K22778732255861622836472581MQ

I’m not sure who thinks this is a riddle? or where it came from?

I would like a link to this cite before I proceed. Never mind…

It appears to be links to individuals websites via their provider. Perhaps some e-theft going on? Try cutting the message into strings of data and do a search on them. They all come back to profiles of members of www.hostobserver.com

Mods. not sure on the ethics and/or legal issues this may bring about. Perhaps I’m just wrong and this is a coincidence. Either way, delete this post if it’s problematic.

See ya~

I did that too, t-keela. The reason I think that happens is because Base64 is often used by websites to encode long strings of data in URLs.

Yes, these are definitely the ISP for hostobservers clients. Go to the top link in my first post and check out the new client list. Load a few of them and check their addresses. String all of them together and the “riddle” is found.

Perhaps but it seems funny that all of the new clients in the list are the same as the strings in the “riddle”.

Just the conspiracy nut coming out in me I guess.

That’s good detective work, t-keela. I never would have thought of that. I was stumped. Well done.

I really think the base64 thing is a red herring. Base64 generally comes up with high-entropy results, and these puzzle values are clearly very low entropy. Each 4 byte group has 4x7=28 bits = 268million possible values. And there seem to be only 8 actual values (perhaps 10 if you include the ending MA and MQ).

Yes, t-keela is clearly on to something, and perhaps this is the only answer. But there must’ve been some reason Host Observer picked these values, and it’s certainly not intuitive. They could’ve used simple unique integers for each company ID. There are many benefits to using an integer in their back-end coding. But they didn’t. There must be a reason.

Also, there’s this whole neat layout of 4 rows x 26 entries per line. I think there’s more to this, but I haven’t got it.

The original post is from www.riddleplanet.com

and it is exactly has I have posted.

question 5.25 btw.

Apparently you can’t see the riddle without answering all the previous riddles. I did find this in the www.riddleplanet.com forums though:

Pavlos, I’m skeptical about the accuracy of your OP as the forum discussions don’t match what you posted. In particular, there are references to "MDENCjAx, DQox, MQ0KMTEx, MDENCjEx
". Also, it apparently was posted not broken up as you posted here.

Please go to the page where the riddle appears, right click, choose “Properties”, where it says "address (URL), select the url with your mouse, type ctrl-c to copy. Then come here and paste the result here, so others can see the original. (I’m assuming you use Internet Explorer). It should look something like this:

BTW, for others, here is the discussion at riddleplanet. There are some interesting observations there about frequencies, etc.

It lokos like, having followed the thread through on riddleplanet, the riddle was actually changed at a certain point, so earlier discussion was related to a different sequence than was posted for this thread. fwiw, here are the original and subsequent versions, according to that message board:

As above.
I don’t know if it was changed at all, I only got there yesterday.
