Wireless Carrier Abuse Of Location Data Makes The Facebook, Cambridge Scandal Look Like Amateur Hour

from the we-need-outrage-symmetry dept

As we've noted a few times now, however bad the recent Facebook and Cambridge Analytica scandal was, the nation's broadband providers have routinely been engaged in much worse behavior for decades. Yes, the Cambridge and Facebook scandal was bad (especially Facebook threatening to sue news outlets that exposed it), but the behavior they were engaging in is the norm, not the exception. And watching people quit Facebook while still using a stock cellphone (which lets carriers track your every online whim and offline movement) was arguably comedic.

As the recent Securus and LocationSmart scandal highlights, wireless carriers pretty routinely sell your location data to a laundry list of companies, governments, and organizations with only fleeting oversight. And while some lawmakers are pressuring the FCC to more closely investigate the scandal (which resulted in the exposure of wireless location data of some 200 million users in the U.S. and Canada), few expect the same FCC that just killed net neutrality to actually do anything about it.

When the previous FCC tried to pass some pretty modest privacy protections last year requiring that ISPs be more transparent about all of this, ISPs quickly took advantage of a cash-compromised Congress to scuttle those protections before they could even take effect:

This collective apathy to routine telecom sector privacy abuses has been going on for decades. You might recall that multiple ISPs were accused years ago of collecting and selling consumer clickstream data. When they were pressed for details, many simply either denied doing it or refused to respond. As more sophisticated network gear like deep-packet inspection emerged, ISPs began tracking and selling your online browsing habits down to the millisecond, some even charging users extra if they wanted to protect their own privacy.

But things got immeasurably more profitable once wireless carriers began tracking user location data, which they now sell to everyone from urban planners to government agencies. Companies like Verizon Wireless were subsequently caught covertly modifying wireless user data packets to track users around the internet without telling them. It took security researchers two years to even discover this was happening and another six months of public shame before Verizon even provided an opt out option (a more powerful version of the tech is now being used by Verizon's Oath advertising brand).

And yet even in the wake of the LocationSmart fracas, which literally exposed the private data of nearly everybody in America, we're still somehow only seeing a fraction of the media, regulatory or public outrage we saw during the Facebook and Cambridge kerfuffle:

"You might think that the major wireless carriers would be facing intense pressure to account for their lax handling of customers’ data. You might think the story would be all over newspapers’ front pages and cable news. You might think their CEOs would be hounded by the media, as Facebook’s Mark Zuckerberg was after the Cambridge Analytica story broke. You might think they’d be dragooned into testifying before Congress.

You might think that, if you expected a reaction commensurate to the one that accompanied the Cambridge Analytica revelations. And it’s conceivable that it will still happen. But so far, there has been none of that."

It remains odd that the press and public still don't realize how deep this particular rabbit hole goes. And whereas the Cambridge scandal made headlines for months, the location data scandal has barely registered a fraction of the collective outrage in media coverage or in DC. Meanwhile, wireless carriers are effectively refusing to even acknowledge they work with companies like LocationSmart, and there's little to no indication accountability is heading their direction anytime soon.

Nearly Everyone In The U.S. And Canada Just Had Their Private Cell Phone Location Data Exposed

from the Whoops-a-daisy dept

A company by the name of LocationSmart isn't having a particularly good month.

The company recently received all the wrong kind of attention when it was caught up in a privacy scandal involving the nation's wireless carriers and our biggest prison phone monopoly. Like countless other companies and governments, LocationSmart buys your wireless location data from cell carriers. It then sells access to that data via a portal that can provide real-time access to a user's location via a tailored graphical interface using just the target's phone number.

Theoretically, this functionality is sold under the pretense that the tool can be used to track things like drug offenders who have skipped out of rehab. And ideally, all the companies involved were supposed to ensure that data lookup requests were accompanied by something vaguely resembling official documentation. But a recent deep dive by the New York Times noted how the system was open to routine abuse by law enforcement, after a Missouri Sherrif used the system to routinely spy on Judges and fellow law enforcement officers without much legitimate justification (or pesky warrants):

"The service can find the whereabouts of almost any cellphone in the country within seconds. It does this by going through a system typically used by marketers and other companies to get location data from major cellphone carriers, including AT&T, Sprint, T-Mobile and Verizon, documents show.

Between 2014 and 2017, the sheriff, Cory Hutcheson, used the service at least 11 times, prosecutors said. His alleged targets included a judge and members of the State Highway Patrol. Mr. Hutcheson, who was dismissed last year in an unrelated matter, has pleaded not guilty in the surveillance cases."

It was yet another example of the way nonexistent to lax consumer privacy laws in the States (especially for wireless carriers) routinely come back to bite us.

But then things got worse.

Driven by curiousity in the wake of the Times report, a PhD student at Carnegie Mellon University by the name of Robert Xiao discovered that the "try before you buy" system used by LocationSmart to advertise the cell location tracking system contained a bug, A bug so bad that it exposed the data of roughly 200 million wireless subscribers across the United States and Canada (read: nearly everybody). As we see all too often, the researcher highlighted how the security standards in place to safeguard this data were virtually nonexistent:

"Due to a very elementary bug in the website, you can just skip that consent part and go straight to the location," said Robert Xiao, a PhD student at the Human-Computer Interaction Institute at Carnegie Mellon University, in a phone call. "The implication of this is that LocationSmart never required consent in the first place," he said. "There seems to be no security oversight here."

The researcher notes that one of the APIs in the portal was not properly validating the consent response, making it "trivially easy" to skip the portion where the API sends a text message to the end user attempting to obtain consent (Brian Krebs, who first reported the vulnerability, has also confirmed the problem). Given the New York Times story had been making headlines since its May 10 publication, it's obviously possible that others discovered the vulnerability. LocationSmart has since pulled their location data tracking portal offline.

Meanwhile, none of the four major wireless carriers have been willing to confirm any business relationship with LocationSmart, but all claim to be investigating the problem after the week of bad press. That this actually results in substantive changes to the nation's cavalier treatment of private user data is a wager few would be likely to make.
