Facebook Flaw Exposed Private Photos

Velcroman1 writes "A security hole in Facebook allowed almost anyone to see pictures marked as private, an online forum revealed late Monday. Even pictures supposedly kept hidden from uninvited eyes by Facebook's privacy controls aren't safe, reported one user of a popular bodybuilding forum in a post entitled 'I teach you how to view private Facebook photos.' Facebook appears to have acted quickly to eliminate the end-run around privacy controls, after word of the exploit spread across the Internet. It wasn't long before one online miscreant uploaded private pictures of Facebook founder Mark Zuckerberg himself — evidence that the hack worked, he said."

      And no friend of yours uses facebook?
      And no one you ever was in a party with?
      And no one who has your adress in their gmail contact list?

      Facebook is a threat not limited to its users.

    If you upload something to Facebook, assume anyone can see it. Whether it's a genuine hack, somebody figuring out your password, or leaving a computer logged in while you go grab coffee, somebody will at some point have access to everything, so don't upload it in the first place. It's that simple.

    That means don't complain profusely about your boss every day, don't send explicit messages to you lover, and certainly don't use Facebook to archive those pictures of that wild bachelor party.

      But I hate my boss; he's a total asshole! And my boyfriend loves getting steamy messages (hey, Brian, I'm not wearing panties today. Surprise for when you get home after work! ;) ), and I archive all the bachelor parties that I perform at. I need to have a portfolio after all! How will the next bachelor party find out if they want me vs. that skank across town?

  5. A bug? In software? OH MY! by bennomatic · · Score: 5, Insightful

    Mistakes happen. Things get through QA. When a bug occurs, if it's in a flight control system, you might crash. If it's in a backup system, you might lose data. If it's in a social network, you might block users you didn't mean to, or you might open your data to unwanted eyes.

    Unless we're going to start regulating social networks like we do products for some other industries, then, well, there's a reasonable likelihood of this sort of thing happening on a regular basis. If you don't like it, don't share stuff on Facebook.

  6. Surprisingly weak architecture by matthaak · · Score: 5, Insightful

    I think this story is revealing about Facebook's security architecture. One would have hoped that security policies are defined within the application at a very low level and that all requests for information -- be it photos, posts, whatever -- must pass through that low-level security layer. What this story reveals is that the security architecture of Facebook is such that each developer of each separate function (in this case, the report-a-nude-photo function) is responsible for re-implementing security checks.

    Please know that on Facebook, whatever your privacy settings are, your photos are only secured by the obscurity of the URL. The Facebook servers that serve static content do so efficiently by doing nothing else. No cookies, no session management, etc. If you happen to know the url of an image (not the facebook url that wraps the image but the actual resource url) you can view it from anywhere whether or not you are logged in.

      In addition to that if you have the static URL to the photo it persists after the photo has been deleted as well. I tested this by loading a URL after a photo had been deleted from the profile and voila! Its still there.

      So creeps, grab those URLs from your cache while you can.

      If the deleted content is still there a week or more later, then you've got problems.

      We're talking about Facebook here. The content is never deleted, and that's by design.
