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."
Facebook privacy violation? *shockface* I'm sure glad I don't use Facebook.

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.
You do not have a moral or legal right to do absolutely anything you want.
I wonder what constitutes a "private photo" for Zuckerberg, my guess is he has no photos that would be even remotely interesting since he knows the ins and outs of FB, and why does spell check want to turn "zuckerberg" into "rubbernecker"?
It's all related somehow...
"If any question why we died, Tell them because our fathers lied."
I saw a link to the forum discussing this somewhere. From the description of the "hack", I was certain this is a hoax. 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.
So it really sounded like a hoax to me to have people go around reporting private profiles of hot girls (or even boys I guess), and I am surprised it is a real security flaw. Not that you can call something on facebook a security flaw, since that would require security in the first place, right?

Wasnt Zuckerberg himself who said some years ago that whoever wants to have privacy is guilty of something?
A squirrel dying in front of your house may be more relevant to your interests right now than people dying in Africa. -Mark Zuckerberg
No Mark,
The private pics of the girl I crush on, yes, those are more relevant to my interests than people dying in Africa. Thank you for giving me occasional glimpses of hope with your privacy blunders.
Yours Sincerely,

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.

Inconveniently, tiny networks are dubiously useful for most of the purposes to which people put facebook, network effects and all that.
It's not my cup of tea; but the notion that one could usefully improve one's security by simply replacing facebook with a personally implemented private network is roughly similar to the notion that one can usefully improve one's security by severing one's LAN from the internet.
Both are true; but not terribly useful for most users.
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.

I decided it was real when I saw someone post Zuck's photos.
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.
The pictures.
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.
