The FBI Issued the following challenge yesterday.
CAN YOU CRACK A CODE?
Try Your Hand at Cryptanalysis 12/29/08
Last year, we challenged you to crack a code created by the “crypt analysts” in our FBI Laboratory, who are experts in breaking ciphers of all kinds.
Tens of thousands of you did so.
Are you ready for round two? We hope so. But bear in mind, this year’s code is slightly more difficult.
Once again: if you want a primer on basic cipher systems and how to break them, see the article “Analysis of Criminal Codes and Ciphers.”
And if you’re a youngster, we suggest you start with the code on our Kids’ page.

It took me less than 10 minutes to crack it, come on FBI! Next time don’t make it so obvious, its a simple substitution cipher and you really shouldn’t need any hints because it is extremely easy. But in case you are wondering, look for a familiar pattern. Assume it is the most obvious answer and go from there. If you want to know what it says and how to crack it read on, but give it a try first it is really simple.
For those of you that are lazy or don’t have time, look closely at the code you will see the following line YYY.AHB.MSK/NSCDC.OFZ now if you have been alive for the past 15 years you will certainly recognize that pattern as a URL address. So assume the most obvious answer and you get WWW.FBI.GOV/*****.*** from there you can already substitute several letters in the rest of the cipher but as you probably noticed NSCDC.OFZ is not cracked yet. But again if you have been paying attention you will know that most Internet pages end in HTML, or HTM so assume the obvious again and you get WWW.FBI.GOV/*****.HTM now you have several letters to substitute around the code. Once you do this several patterns will emerge that will help you assemble words and the final result is below.
CONGRATULATE YOU ON
