TransUnion Says Hackers Stole 4.4 Million Customers' Personal Information (techcrunch.com) 70

An anonymous reader quotes a report from TechCrunch: Credit reporting giant TransUnion has disclosed a data breach affecting more than 4.4 million customers' personal information. In a filing with Maine's attorney general's office on Thursday, TransUnion attributed the July 28 breach to unauthorized access of a third-party application storing customers' personal data for its U.S. consumer support operations.

TransUnion claimed "no credit information was accessed," but provided no immediate evidence for its claim. The data breach notice did not specify what specific types of personal data were stolen. In a separate data breach disclosure filed later on Thursday with Texas' attorney general's office, TransUnion confirmed that the stolen personal information includes customers' names, dates of birth, and Social Security numbers. [...] It's not clear who is behind the breach at TransUnion, or if the hackers made any demands to the company.

        Because not everyone who has credit today had credit back then. It's important to fix this recurring problem today for the benefit of future generations. "A society grows great when old men plant trees whose shade they know they shall never sit in." (Greek proverb)

        Monopoly? There's also Equifax and Experian. If anything, credit bureaus make the lending industry more competitive by centralizing the risk management aspect at in independent third party. Without them, you'd end up with a cartel of banks that shared risk information between members and any new competition would be locked out.

            If it really bothers you, start a grassroots movement to have a law passed to require them to delete your data upon request. No credit is effectively just as bad as bad credit, so if that's what you really want, have at it.

          They co-operate and are owned by the same people. Think oligarchy and corporatocracy. From one perspective, the entire 'credit score' industry is basically centralized economic surveillance, no one gets credit unless they agree to being financially surveilled and classified. This is exactly what classism looks like.

          • no one gets credit unless they agree to being financially surveilled and classified.

            Which is exactly the same thing banks would do on an individual level without some sort of centralized risk repositories. You want to see what credit looks like without credit checks? Those businesses do exist, but you'd likely want nothing to do with them because they're even scummier than the major banks that pull your credit.

    • If the whole dataset is 4.4M, that suggests it's more direct customers, rather than third party reporting. I'm guessing TransUnion has third party data on most Americans who have ever used credit, so that would be way more than 4.4M.

      It's probably closer to the number of people who sign up for credit reports.

    • From the summary, this appears to have been a deliberate act by an employee, who used unauthorized software. It's not clear that the company itself, or its security policies or regimens, are actually at fault here.

    The safety of a normal building is ensured in part because we require by law that it follow a building code, and that it be inspected, with fines if they don't fix it. Otherwise buildings would be built cheaply and shitty and falling down on us all the time.

    We need a building code for the technology that critical companies (like the credit bureaus) use. Otherwise they will just keep having shit security and we will all be hacked constantly forever.

    • Yep. And once upon a time, before building codes, buildings used to be built that way. Building codes took centuries (millennia!) to develop. It was not immediately obvious what needed to go into them, and the politics of the whole matter complicated things further. Computer system codes will likely take the same, at least, since computer systems are not as simple as buildings.

    • isn't that basically what PCI, HIPAA and such were supposed to be?

    • Buildings are all generally the same and are built according to plans that are formalized in advance. Every piece of software is unique and evolves.

      Builder: How many floors do you want in your building?
      Customer: We're not really sure. Start with two, and we'll see how many more we need after we start moving in.

      Years later, a 50 story building collapses because it's made of wood.

    • Building codes exist for two reasons:

      insurance companies got tired of the expense of covering death traps.

      those buying a house don't want to buy a death trap - or more specifically the banks making the big loans to buy a house didn't want to be stuck losing everything when that death trap falls apart or goes up in flames killing the 'owner' leaving the bank with nothing but land with a junk pile.

      Sure, codes indirectly protect your life - but make no mistake they exist primarily so that your debt ca
    • You don't need codes. You need liability and insurance.

      Say - for example - a builder wants build a 4 bedroom $1M house. They might have to attach a bond to that build before sale that would cover $1M for the house replacement, $250k for restoration/cleanup of the property in case of total loss, $1M for each bedroom in life insurance, and $250k for property inside, totalling a $5.5M insurance policy on the build.

      That bond would stay with the house for 30 years, after which the bond and any interest accrued g

      • I'm a fan of liability.

        The media industry had a fine law passed (https://www.law.cornell.edu/uscode/text/17/504 [cornell.edu] that set minimum statutory damages at $750 to $30,000 per copyright violation. It could, of course, be more.

        I think that the same law should be written for personal information - statutory damages of $1000 to $10,000 per event, set by the type of personal information leaked. You leak my name and email address? You pay me $1000. You leak my name, credit card numbers and CVNs, you pay me $5000.

        • Liability is so much better than regulation.

          In my utopian society, corporations would actually be treated like people. And when those people commit crimes, they would go to prison. If no one can figure out who at the company is directly responsible, the whole C-suite and board have to serve time.

        • It gets tricky though. Who is liable?

          Say I write some software, and sell it to other company. It is complicated software, and requires expertise to operate it in a secure manner. Comapny A buys my software, and uses it fine (they have behaved responsibly - proper testing, risk-assessments, etc.). Company B also uses my software, and has a data leak using it (they are slap-dash - no testing, no third party testing, etc.).

          Am I liable here? Company A's situation suggests that my software is fine when properly

      • Except the insurance is just a means to escape or reduce liability, while also creating middlemen who's sole job is to encourage gambling by those liable.

        I.e. Cost of liability is X million, but with insurance that drops to Y million.
        If X > Y then the company will probably avoid the violation.
        If X < = Y then the company will probably consider it a cost of doing business, especially if their premiums don't go up in response. Or they can find some other way to offset the cost. (Pass it along to cons
    • We have them, standards like SOC2, PCI, etc.

      The problem is, like building codes themselves, these standards can easily be circumvented.

      When I was in college, my university built a new auditorium. For aesthetic reasons, they wanted the railings to be lower than was allowed by building codes in effect. So they waited for the inspectors to sign off on the building codes, then lowered the railings to where they wanted them.

In every company where I've worked, the audits only cover specific software that the company builds, and excludes other "legacy" software that the company intends to retire one day. But they never get around to retiring that legacy software, leaving themselves exposed, and effectively lying to their customers about their certification. Further, those auditors often have no clue what they are doing. They ask questions from a script, writing d

  • It's not like anyone chooses Transunion, or Equifax. They have your stuff whether you like it or not.

Switch to some other agency?

    TransUnion sells identity protection services that monitor for exposure of exactly the same kinds of data (name, DOB, SSN) that were themselves stolen in the breach. In other words:

    What they promise to watch for unauthorized exposure of your personal identifiers.

    What hackers actually took from them those same identifiers.

    That’s a bit like a lock company being robbed of its own keys.

    It highlights a fundamental problem: once those “static” identifiers (SSN, DOB, etc.) are stolen, they can’t really be changed. Unlike a password, you can’t just “reset” your Social Security number.

    That’s why breaches at credit bureaus are particularly concerning — they’re custodians of the most sensitive personal data, and when they get breached, the damage is both widespread and long-lasting.

    • Don't worry, if your info was part of this breach, and you paid for their identity protection, they'll send you a nice email saying that your data has been breached. Isn't that worth the money you paid for your subscription?

      • Only if you're a subscriber :-)

        They should put up a page on their site where you can check if your information was in the breach, and if it was, give you, free, more than a year of monitoring (like 5+ years).
        It shouldn't be too difficult to find who it was that did the "unauthorized access of a third-party application storing customers' personal data"... why is the information stored by a third party? It should be stored on a rack of servers in the broom closet, behind like three firewalls on battery backu

  • This seems like the least of our problems when the difference between this incident and TransUnion's entire business model is that they didn't get paid to provide the records this time.

    There FTFY.

  • Life was better for everyone before credit scores were a thing.
    • Was it?

      Before credit scores, it was much harder to get loans, including mortgages. Credit cards weren't a thing (for better or worse). Underwriting processes took much longer. Credit was granted or denied based on whatever whims the lender thought were important, whether they were fair or not. With credit scores, many more people can get funding, than could before credit scores, and the decision making for lenders is much more transparent and data-driven.

      • Except that data-driven narrative falls apart when the data points are stolen and used to manipulate the lenders based on the "credit" of others.

        Those loans are also a lot more exploitative of the person taking them out. (More info for the lender to use during negotiations that isn't easily countered by some random individual.) In some cases allowing the lender to overleverage them.

        • The fact that theft is possible, doesn't negate the value of credit scores. Before credit scores, theft of cash was possible too, and happened very frequently.

          The fact that some people misuse credit or do business with predatory lenders, also doesn't negate the value of credit. You are essentially arguing that the availability of CREDIT is a bad thing, not the credit scores themselves. Credit, like money itself, can be misused. But the availability of credit greases the wheels of the economy and of personal

  • Transunion is a bureau that also offers credit monitoring when your info is leaked in a breach. I wonder if this leak affects those using the monitoring services, effective being leaked twice.

    I also wonder if they will ironically offer those affected by the break a free year of credit monitoring through Transunion.
