back to article Boffins find new ways to slurp private info from Facebook addicts using precision-targeted ads

Facebook’s advertising platform is riddled with loopholes that can help miscreants obtain private information on individual users, according to a recent study. Personally identifiable details – such as someone's email address, full name, date of birth, and home address – are used with their likes and dislikes to slot them into …

    Does the data provide ENOUGH resolution?

    For instance, would it identify someone who, when presented with targeted advertising - or, iindeed any of the mindless trash that gets hawked around - would be quite happy to rip the authors head off and defecate down their neck?

    We might be on to something

    missing the point?

    The platform was designed to invade privacy(paraphrasing Zuckerberg's early quote "dumb fucks"), as were pretty much if not all other social media platforms.

    I'm sure google goes even further they just haven't been exposed to the extent facebook has been yet.

    It is unfortunate that so many people are happy to give up all of this info in exchange for using these services. I saw one headline on a news site I think it was from a U.S. senator saying "facebook should be paying US(the users) for this data!", obviously went over their head that they are giving you value back in "free" usage of the platform, paying for all those developers and servers and data centers etc.

    I would pay money to see what data facebook and google have gotten on me but even if they did offer that service(I think google does to some small extent), I have too much fear that they would then validate "that is me" in their data by me doing such a thing. (I have never had a facebook account, I do have a google accounts for android(I don't use gmail, and use firefox as my browser, and am careful about what apps get installed), and I do have a google account for work for google docs(rarely use))

      Google ?

      Oh they are capturing much more information. So much so, that they don't need to use cookies.

      Ask yourself why do many well known sites still use google analytics? ;-)

      But overall, none of this should be a shock to anyone.

      You are the product. Without you, FB would be nothing.

      Unfortunately even if you don't have a FB account, they are tracking you too.

        If he's a US resident, then his data doesn't belong to him, and whilst he has the right to bear arms he has no right to privacy. And wandering off topic, I suspect the Founding Fathers actually meant "the right to bare arms", intending to confer the freedom to wear tee shirts, instead of every man-jack wandering around shooting people with assault rifles.

    microtargeting

    I wonder what kinds of nefarious things can be done with THAT...

    a) spear phishing

    b) harassment

    c) manipulation

    d) blackmail

    e) evil gossip

    f) get target to show up someplace at a given time

    g) get target to take pictures doing specific things

    h) all of the above

    I can think of many ways to do "all of those", if given the ability to make this happen. Good thing I'm a 'white hat' [ok maybe a slight touch of grey]

    consider what 419eater has been able to do, for example, with 419 scammers. And I really liked that 'Africa' video with the song 'Africa' by Toto. It was a crowning moment of awesome!

      Re: microtargeting

      Now combine that with the users Google credentials and any other accounts assigned to their smartphone along with imei, location data, IP address, phone contact list, photos, musical taste, installed applications (like banking apps) etc etc that can be gleaned by a dodgy Android app and the developer has unlimited possibilities.

      Facebook's Graph and unscrupulous advertising SDK's embedded in apps have created the largest single attack vector ever.

      The Graph API allows advertising SDK's to push advertising and other data into the users Facebook feed and I have seen advertising SDK's that actively view the source code of shared web pages to inject javascript to make users phones vibrate and pop up fake virus warnings to trick users into downloading even more dodgy apps.

      The fake virus warnings or other annoying persistent ads that pop up on Android devices are (almost) impossible to trace because they originate from unsuspecting users devices as they share content on Facebook that has been modified by the SDK's within apps on the sending users device without their knowledge.

      An Android user that views a shared Facebook link or video sent by a user that has a dodgy app installed will be redirected to a full screen fake virus warning while their phone vibrates and usually links to a.dodgy "antivirus" app on the Google Play store to remove the non-existent "viruses" thus continuing the spread of modified Facebook links if the victim installs the dodgy "antivirus" app.

      In order for this to work the person receiving the modified Facebook page or link must also meet certain criteria as far as what apps are installed on their device.

      Most of the offending advertising SDK's I have documented that do this are from foreign countries such as China.

        Re: microtargeting

        I recently implemented a system for a client that used Facebooks advertising API to do some clever tracking.

        The client wanted to track every user who clicks from a Facebook ad and purchases something. He also wanted to track every user who started the checkout procedure but didn't complete.

        This is possible with Facebook pixels. The client wanted to re-advertise ads to all users who had made a purchase. He also wanted to hound the users who didn't complete the checkout procedure.

        How did he do this you might ask?

        Lets say for example my client is selling beds. User clicks through to purchase but for some reason doesn't complete. These are what's called lukewarm leads. The client wanted these users to see ads that promoted reviews, or articles, to warm the user into purchasing. For users who do purchase he then promotes accessories, and related products.

        His idea worked and his business is making a serious amount of money solely from these aggressive marketing tactics.

    Hold on a moment..

    "The minimum number of people in a custom audience is, right now, 20. It’s a low number compared to 1,000 for Google, 300 for LinkedIn, and 500 for Twitter. By peppering in 19 fake or complicit accounts, for example, advertisers, and anyone else curious, can narrowly target and snoop on just a single person, or a group of people by going through them one at a time."

    Yes Facebook might allow a custom audience of 20 - but that's just "interesting"

    Even taking that upper number of 1000. You think there's somebody out there employing a copy-writer to design custom adverts for 1000 unique people?

    Is Zuckerberg embarrassed by how manipulative his baby has become:

    Verification

    Is it too late to get several fake profiles and data past FB's sign on processes?

    Surely, it's time for the authorities to force FB to prove that every one of their claimed 13bn ( ok, ok 2bn) accounts is actually genuine.

    And as for asking for their data ...

    My mate : Hey Facebook, do you hold any data on me?

    FB : Well, click on this link, fill in the form and we'll get back to you.

    My mate : Clickety click. Well do you hold any data on me?

    FB : We do now.

      Re: Verification

      I created a fake fb account many years ago using one of my garbage collecting email accounts that I use to sign up for stuff that I don't care too much about. That account has no friends, and when I check the email to dump it all in the trash it is filled with friend suggestions that are exclusively attractive young women.

      I guess that is because the only profile info they would have is that I'm male and have no friends, so how about you friend this hot, young Romanian "woman", I sure she would be interested in a friendless loser with no apparent job or interests.

    That means advertisers can zero in on their products' ideal buyers, and, say, sling expensive pet food ads at rich dog owners. However, these systems can also be exploited by scumbags to potentially slurp sensitive records.

    Both of which sound bad to me.

    I don't get special ads

    I don't make an effort to block Facebook ads, this is so I can keep an eye on how well-targetted the ads are hence how much they know about me. The ads are not targetted at all; vaguely aligned with my lifestyle for example they have obviously figured out I work in IT but that's about it. Although I can't say I use their system much therefore perhaps they have less to work with.

    Maybe they are not all-knowing, maybe that is just what they pretend to their advertisers?

    Well if personal data is passed to 3rd parties without given consent that constitutes a breach of GDPR and a 4% smack of a fine. Facebook isnt going to be able to take too many of those before it decides to secure personal data better.

    So i'm more than happy that companies will concentrate on spamming us citizens in america rather than those in Europe.
