An interesting article on how pictures could be used to comprise your "secure" computer, I've heard it could be done, but here is an explanation of how it works, and of course how to prevent it.

Great - thanks for sharing David

Nice find, David. I knew image files could be embedded with malicious code but, like you, never really looked into how.

Well I knew if I used stumble upon long enough, they would slip something interesting in between the endless parade of fictitious pie charts, inside jokes over celebrity pictures, top 10 this, best 30 of that, and how to use social media sites to sell your awesomness.

Listen up people... James T. Kirk has it, and he aint selling it!!!
