Security by Candlelight - Crypto Games on teh Interwebs
Security sometimes seems like a hard and long journey
But properly equipped it will be just like snapping with your fingers. I'm afraid we will not have a "Babylon Candle" to get us there but at least it will be much more fun to travel in a group and talk about the things and wonders we see along the road.

In Jan 2012 an image with cryptic content was posted to 4chan /b/, imgur and other internet channels, most of them infamous for little control of the content and very loose interpretation of what could be accepted for a public audience.
It turned out that steganographic content was embedded in the image and soon a hunt began, with lots of speculations and conspiracy theories emerging. None was ever prooved.
We want to take look at some of the cryptographis methods and how they were broken.

A few months later, in Mar 2012, ominous messages were posted on spreaker.com, a web radio channel. It soon spread to (again) 4chan, this time to /x/ the board about conspiracies, paranormal activities, to reddit-sub-boards etc...
The web-casts mostly consisted of a series of numbers, spoken by a female voice. The numbers (in most cases) were encrypted messages with different crypto-algorithms and decryption keys that had to be broken by brute force, crypto-analysis, solving previous challenges or deducting keys from hints found in material referenced or provided.
Again we want to look at some of the methods and how they were broken.
