Facebook Flaw Exposed Private Photos 201

Posted by Soulskill from the somebody's-having-a-bad-day-at-the-office dept.
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."

    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.

      I used to think this, but there are some pretty convincing arguments in The Net Delusion that have caused me to rethink that position. There are a lot of Facebook users, and dissident groups cannot avoid using Facebook to reach people, simply because of the large number of people on Facebook. If Facebook does not take privacy seriously, the risk to dissidents who try to contact their fellow citizens on Facebook will grow.

      The point here is that yes, it is a problem when Facebook unexpectedly opens its users' data to the world against their wishes. There are legitimate reasons why someone might use Facebook but want to keep their account data private.

        You do realize that Facebook privacy terms only apply to other users who use Facebook for free, and follow the terms of service, right? Facebook hackers, bots, and government agencies (and likely some large corporations) have full access to Facebook data. So does Facebook. Not only is your "private" Facebook data fair game, so is the "hidden" Facebook data, such as your access log, answers to security questions, access patterns (when you did what), etc.

You see, the idea is that the hack is to report the user with private pictures to facebook as having "nude/pornographic" images, and in the image flagging process it shows you private-only pics as well.

    The other day I finally got around to configuring those privacy settings that everyone has been so on about. Facebook sure doesn't make them easy to find.

    I was shocked to find that my account granted access to about three dozen apps that I never even heard of. There were only two or three that I signed up for with my own conscious knowledge. I don't have the first clue how I got signed up for all the rest.

    That just pissed me off. As I was no longer actually using the two or three apps that I did voluntarily use, I deleted all three dozen from my account.

    You may be completely unaware that a whole bunch of private companies that are not affiliated with Facebook have access to your personal data. Even if you want to use a particular Facebook app, you should configure that particular app's privacy settings to grant it access only to the data you voluntarily want it to have. If you are no longer using an app, or don't recall ever requesting the use of it, you should delete it from your account completely.

    Here's what you do:

    Log in to your Facebook account. (Heh, when I did that just now, I found my account locked. It turned out to be because I had deleted my cookies, not because Facebook caught me spreading the word about how to dump what Facebook considers to be its real customers!)

    At the top-right is your username, "Friends", "Home" and a small triangle. Click on the small triangle then select "Privacy Settings".

    Click on "Edit Settings" to the right of "Apps and Websites". You may need to scroll down a little bit.

    Click on "Edit Settings" to the right of "Apps You Use".

    I no longer use any apps so I can't continue from here, but at this point it should be pretty clear what to do.

    Some apps really will require access to your details so they can function. If so, be certain that you really want to continue using those apps. Give them the minimum level of access that you really want them to have. Delete all the rest.
