I’m sure almost everyone saw dramatic and scary images of “Hurricane Sandy” like this one that went round my friends’ Facebook timelines yesterday:

As you’ve probably guessed from the title, this is a ‘shopped image. RJS Security has a quick primer on detecting doctored images using this example:

Whenever a major media event happens (like Hurricane Sandy), we are inundated with news. Sometimes that news is useful, but often it merely exists to create FUD… Fear, Uncertainty and Doubt. While I have not personally seen any malware campaigns capitalizing on the event yet, it is inevitable. The pattern is generally as follows:

  1. Event hits the news as media outlets try to one-up eachother to get the word out.
  2. People spread the warnings, making them just a little bit worse each time they are copied.
  3. Other people create hoaxes to ride the wave of popularity.
  4. Still other people create custom hoaxes to exploit the disaster financially.

A few minutes ago, at least in my little corner of the internet, we hit stage 3 when this image was posted
