Researchers Show How Europe's Data Protection Laws Can Dox People (vice.com) 52

An anonymous reader quotes a report from Motherboard: Europe's controversial privacy law, the General Data Protection Regulator -- better known as GDPR -- has been hailed by some as a solution to tech companies' pervasive data collection and tracking. What maybe no one saw coming is that GDPR can become another tool in the arsenal of enterprising and malicious social engineers, hackers, and people who want to dox and harass others. That's what Ph.D student and cybersecurity researcher James Pavur discovered when he and his fiance -- and co-author on their paper -- Casey Knerr made an unusual wager about using GDPR's right of access requests -- a mechanism that allows Europeans to ask any company about what data they have on themselves -- with the goal of extracting sensitive information.

Along with his fiance Knerr, who also works in the infosec industry -- and with her full consent -- Pavur devised a clever, yet very simple experiment. He started with just Knerr's full name, a couple of email addresses, phone numbers, and any other low-hanging fruit that he could find online. In other words, "the weakest possible form of attack," as he put it in his paper. Then, he sent requests to 75 companies, and then to another 75 using the new data -- such as home addresses -- he found through the first wave of requests using an email address designed to look like that of Knerr. Thanks to these requests, Pavur was able to get his fiance's Social Security Number, date of birth, mother's maiden name, passwords, previous home addresses, travel and hotel logs, high school grades, partial credit card numbers, and whether she had ever been a user of online dating services.
"Pavur and Knerr said 25 percent of companies never responded. Two thirds of companies, including online data services, responded with enough information to reveal that Pavur's fiance had an account with them. Of those who responded, 25 percent provided sensitive data without properly verifying the identity of the sender.

Another 15 percent requested data that could have easily been forged, while 40 percent requested identifying information that would've been relatively hard to fake, according to the study.

        I’m not so sure the cookie law had a lot to do with good intentions. Everyone remotely knowledgable about IT warned beforehand that the law would only lead to annoyance while solving nothing.

        The GDPR is another matter. And what TFA deceives is not so much a problem of the law, but of companies not properly verifying identities or even understanding basic authentication or security. It’s nothing new either, hackers used similar methods to obtain SIM clones from providers in order to hijack high profile social media accounts. The solution is not do do away with the GDPR.

        So what would be your solution? Not allowing me to ask companies what data they have on me? Also, note that providing the personal data to someone else than the data subject is clearly a violation of GDPR - so to me, it does not seem like a failure of the legislation.

        Silly generalisations aside (no it doesn't "always happen") this is not the result of this law but rather a complete lack of due diligence by companies. The likes of Facebook and Google have policies to hand over your data long before GDPR existed. All the GDPR did was mandate a similar mechanism. Likewise we have had an endless string of social engineering attacks in the past 10 years handing over complete control over an account to some 3rd party, in some cases with quite public effects such as the releas

    This has nothing inherently to do with the GDPR, and everything to do with companies not having a proper, legally approved process for handling Subject Access Requests or simply not following their approved processes - it's pretty much certain that these same companies that failed in this test would have failed under the older UK Data Protection Act requests as well (which are broadly similar in terms of Subject Access Requests as the GDPR).

    In short, it's a hit piece on the GDPR - the same would have happened under the UKs pre-GDPR data laws as well.

        There is copious guidance given by the EU and various individual governments on how to implement these checks.

        And when businesses have been fucking up with peoples data and privacy so badly like they have ever since the internet became a thing, the government certainly has business getting involved in business - the GDPR is a good thing, businesses need to understand that my data is no longer theirs to do with as they wish. The American ideal of "the market will sort itself out" is patently false and broken when it comes to consumer protections.

            This would be unpractical to the point of making the GDPR moot. Most people from, say, Romania wouldn't be able to just make a trip to Irland to appear in person at the Facebook offices there to prove their identity. And that's just looking at the GDPR within the EU. The GDPR also governs companies from all over the world that do business within the EU. Travelling to the States or to Asia just to prove ones identity would be impossible to practically everyone.

          In Europe especially you have to hold a lot of information by law. Whether it's tax law, employment law, terrorism law, copyright law - most transactions are required to be kept track of in great detail so the government can later demand them directly or report on them.

          Point in fact, if you read the GDPR you are required to keep track of any data used just to make a query whether the data exist. So even if you don't keep data if anyone, if anyone asks, you are now required to keep track of their data just s

        I have no sympathy for these companies. They had years to get their systems straightened out, the rules are clear and compliance isn't difficult at all. They just didn't bother, and even a few years down the road are often incapable of servicing these legal requests properly.

        That tells us that they probably aren't handling our personal data properly either. We need to get to a point where personal data is properly protected, and any company that can't reach that low bar needs to stop processing it.

        I've submitted nearly 100 SARs so far. Some of them are very smooth and properly managed, but many are not. I had trouble with PayPal, for example, because they needed me to log in to make the request. I don't have an account. That one had to go through two national regulators to get fixed. Apple had the same problem but were able to fix it rather more quickly.

          Having a single IP address in your server logs is enough to require GDPR compliance. And then, as I said, you are required to collect more information just to keep track of that IP address just so later some SJW or criminal can demand whether you have any information on their (perhaps illegal) actions and delete it, which you can't because of EU terrorism and copyright regulation.

          • Having a single IP address in your server logs is enough to require GDPR compliance.

            If he IP address isn't sufficient to identify a person then no you don't have to. And if you're worried, then don't log it forever. There is no requirement under the GDPR to instantly respond to any deletion requests, so delete your logs and you're fine.

        It's not up to the government to change your diapers. When we live in a world of a government that actively prevents you from being negligent through regulation that is called a "nanny state" and it's a bad thing.

        The government should not end up holding the cost. I'm no fan of the USA "sue everyone" approach, but I do wish in Europe people would take a more active role at punishing companies who are negligent (such as handing over your data without due diligence) and not rely on governments to do it.

    • You mean private companies don't magically run themselves with the same accountability as government employees just because someone passed a law? NO WAY. INCREDIBLY SHOCKING.

      The submissions point is damn important. The EU has "legislated" a mechanism with checks to actually ensure it isn't being abused. They might as well be legislating that the sky should be sunny--they'd have a higher compliance rate in most countries.

      • Yeah, fuck legislation, it doesn't solve anything. Let's get rid of it. All of it.

        Companies that fail to do proper identification checks for Subject Access Requests can be referred to the information commissioners office and face large fines - fines designed to actually threaten a companies existence if they continually fail to act properly.

        So yeah, the EU legislated, and they also legislated teeth for it. Like a legislative body should.

    Europe's controversial privacy law, the General Data Protection Regulator -- better known as GDPR

    Two problems with that line...

    1. The R in GDPR stands for regulations, not regulator.

    2. The GDPR is about as uncontroversial as it gets.

    A large part of the public does not care about it. Those of them who had, immediately dropped it when they found it was "to do with computers" and they think that phones are something else. They haven't clocked that it applies to paper, CCTV and all sorts of other stuff.

    Those of us who work in information systems do not find it very controversial either. Certainly, it is a hassle, but so are speed limits, planning rules and waste recycling rules. I can follow them quite happily (even the speed limits if I am paying attention) as they exist for good reason. GDPR is a positive update of previous laws.

    The only objections I come across to GDPR are from websites in the USA who object to the idea that their misuse of my data might be curtailed. There are some who have just not got round to dealing with it. After all, it is not much more than 3 years since the whole thing was finalised and made available. It is only 12 months since it went live...

  • What a shock. GDPR not only fails to provide any benefit, costs tech companies millions, and, oh yeah, provides a new attack vector to malicious actors.
