VB2015 'Steganoprague' competition

Posted by   Virus Bulletin on   Sep 30, 2015

Use your steganography-detection skills and win a pile of books.

As VB2015 is about to begin, we announce the second part of the 'Steganoprague' competition. In this part, you will have to find URLs hidden by others inside an image provided by us.

The puzzle can be played by anyone, but if you are attending VB2015, you can win seven books on computer security. The winner will be the person who finds the greatest number of URLs or, if people find an equal number of URLs, the person who does so in the shortest time.

Once you've found a URL, send it by email to martijn.grooten@virusbtn.com. The deadline for the competion is 12:30 Prague time on Friday. The winner will be announced during the closing address later on Friday.

Please see the description of the puzzle for the rules and for the original image.

The three images for the competition are:
