   What does your discovery mean for internet users?   
      
   It means that there are advertising banners with "poisoned pixels" leading to   
   a new exploit kit, intended to enable the bad guys to remotely install malware   
   onto victims' computers. The victim doesn't even need to click on the   
   malicious ad content; all it takes is to visit a website displaying it. If the   
   victim's computer runs a vulnerable version of Flash Player, the machine will   
   be compromised via an exploited vulnerability automatically.

   Where are the poisoned pixels in this?   
      
   Well, the name "Stegano" refers to steganography[1], which is a technique the   
   bad guys used to hide parts of their malicious code in the pixels of the   
   advertisements' banners. Specifically, they hide it in the parameters   
   controlling the transparency of each pixel. This makes only minor changes to   
   the (color) tone of the picture, making the changes effectively invisible to   
   the naked eye and so unnoticed by the potential victim.
