back to article All your base are belong to us: Strava exercise app maps military sites, reveals where spies jog

In November, exercise-tracking app Strava published a “heatmap” of user activity which it cheerily boasted comprised a billion activities, three trillion lat-long points, 13 trillion rasterized pixels and 10 TB of input data. It took a while, but late last week someone wondered “how many Strava users are members of the …

      There are all kinds of privacy setting the users could have employed. If they couldn't be bothered to switch any of them on you can't blame the service.

        Yes you can. You can blame them for not making the privacy setting default to something sensible. This amounts to an offence under GDPR.

            I'd be surprised if it isn't already an offence under the current regulations. They are a processor of sensitive data (where someone is) under DPA, and they cannot just publish all that information in such a way that it can be deanonymized. Obviously showing you coming out of your house is not very anonymous. They might also be in trouble over various national security legislation. Arguably this is material of benefit to terrorists, and its publication would then be an offence under UK law. (Find any route that goes into a military base, for example, and then wait along it.)

              "They are a processor of sensitive data (where someone is) "

              You can look up sensitive data on the ICO website:

              https://ico.org.uk/for-organisations/guide-to-data-protection/key-definitions/

              It doesn't include location.

              Excluding home addresses *is* part of the Strava sign up process. And Strava's privacy policy explicitly acknowledges that people may be identified from aggregate data:

              "If you make information or content publicly available on the Services, such information, even when aggregated, is capable of being publicly viewed and possibly associated with you"

              There are plenty of bad boys in the industry, but Strava isn't one of them.

              They have consent under current DPA for everything they do. They have consent under GDPR, although I don't think they need it (because storing location and deriving profiles from it is the whole reason for the service existing).

              Need to go now, time for my daily catch-up with the GDPR lawyers.

                Very much this, what surprises me is how many people miss it. I compared my friends house in LA with mine, he is obviously the only person living on his street to use the app despite a reasonable number of people using it as part of their running route. My house in a small town in the UK has apparently never been lived in by someone who has Strava even though I ran about 5 times the distance he did last year.

                What I did like was looking in Portsmouth harbour and seeing a feint outline of an aircraft carrier.

                    The Data Protection Act (DPA) applies to data controllers that are either:

        Strava is a data-collection site. That's what it does. You opt-in by uploading your stuff to jt, it doesn't magically track you without consent.

        When I signed up the privacy zone was in the initial setup wizard, so it's a little deceptive for the article to call it off by default. It has to be off as far as it is, because Strava doesn't know where to put it unless you tell it.

        Heatmap is just another example of it being really hard to anonymise through aggregation.

      It's not PII though. The fuzzy line shows where some of the millions of users have been. The only reason you know a line to a front door is your friend is because YOU have Personally identifiable info on your friend, like where they live and the fact that they use Strava. Without that information it may just as easily be the postman or a stalker, and the heatmap gives you no more useful information than that. "privacy experts" are driving me insane at the moment, GDPR is like cat nip for dipshits.

    Why people use and publish results from apps such as this.

    Every day I see on social media people posting their running/cycling etc details online. I can literally deduce their home address and what time they enter/leave from here. Even from people I don't know too well.

    I'm not a nasty guy, but plenty of people are and they can use this info for not so nice purposes. Seems like common sense isn't too common.

      The problem with Strava is by default it shares it with the world. If you're just sharing the data with your friends*, they probably already know where you live.

      Re: I've never understood

      I've seen this with some female Facebook friends, and pointed out to them that it makes it easy to figure out where they live. Some care, and correct it, others say "it isn't that hard to find out where someone lives" and don't worry about it.

      I suppose that's basically the same argument that you get against "security through obscurity".

      1. Pascal Monett Silver badge

        @ DougS

        You might remind your female friends of a basic difference : IRL, someone has to meet you, or at least be told about you, before they think of looking you up. I doubt that stalkers choose their victims by perusing the phone book. If they don't know your name, they can hardly look up your address and they'd have to follow you home before they can correlate an address to a name.

        Publishing personal info and travel data on a social site removes that sleuthing requirement. The stalker can just peruse the activities, select a woman he likes and dive into her life. Finding the address is trivial at that point.

        Security through obscurity works very well in real life. Do you know where US carrier fleets are at this time ? Hint : don't try finding out - that will land you in very hot water.

      Re: I've never understood

      There are basically two reasons. One is that competition is a strong motivator. For a lot of people, including me, leaderboards can motivate people to go out more, or to push faster/further than they might have otherwise. Another is helping to cheer each other on. I have three friends on MapMyRun, I know that the encouragement I get from them is helpful when I'm not doing so well and I certainly hope it works the other way too.

      That said, there are good and bad ways to share this data. For example, on MMR those three friends are the only ones who get to see exactly where I've gone, or whether I've gone at all on runs that don't earn me a place on a leaderboard. All anyone else sees is first name, last initial, time on that segment, and date. I *could* open up full sharing, but it's not a default. No heatmaps or anything like that, though I've kind of wished for that as a way to help people find routes worth trying. Overall, I'm pretty comfortable with MMR's approach. If I used Strava, I think I'd be a bit less comfortable.

      I also suffer from a terrible memory ("the worst case of sleep apnoea in someone of your age and build" means I literally spend half my time sleeping not breathing, so I never hit L3 sleep) so it's useful for tracking when I've been, how much I've done this month and should I do more.

          Just I download them to my computer only, and the data never leave it (of course, the photos with geoloc data are never uploaded to any site or cloud service...)

          The day those devices start to attempt to upload them to whatever cloudy destination, I'll stop using them.

          I don't really want someone could track where I'm while carrying several thousands $$$ of equipment...

      Good point, I don't share to social media as I see many do and I have security zones set around work and home to obfuscate to some degree where I live and work. Only "friends" can actually see my stream and I have to confirm each friend request (I believe by default the system allows anyone to follow you, it's an opt-in setting, but, shouldn't checking security settings be the first thing you look at when signing up to any online system, or is that just me?).

      As my use is mostly for, well, my use again I can see where my usage diverts from the majority of users. That all said, I don't think most care and it isn't really a big deal, those in government positions and especially armed forces should really be given a briefing on securing their online presence though and to think through usage of such platforms.

    In defense of former and current serving military members, they were encouranged to buy and use the devices to improve physical fitness. DoD even gave away 25,000 of the devices as I recall. So the fail isn't at lower ranks alone.

    This really bothers me. While I wore the uniform I spent quite a bit of time wandering around with an M1911A1 .45 calibre pistol strapped to my right hip. I made damned sure that I randomized my check-in times and routes to there and on the rest of my patrol. Really, really random. You never knew how I was going about my affairs. I wanted to remain alive, thank you ever so much. That a device whose use is encouraged by the chain of command negates all that, or at least puts some of the rest of my mates in danger is disturbing.

Any number of apps on an average smartphone will be sending back location data to the mothership, not just fitness apps like Strava, and the device itself by its nature is a portable beacon. I'd expect rules more like "OFF at all times while on duty or when on or within X km of the base, except in these designated areas".

          It beggars belief that the military aren't all over the security implications of personal mobile devices and rigorously training personnel ...

          Really? Since ages past, the military have handled both Adversaries and Enemies - The adversaries are the expected ones (Napoleon, Russia, China, Terrorists ....). Except, nothing big really happens there, so, when there is not in fact a hot war going on with everyone getting plenty of personnel, funding and glory showered upon them, all of the abundant military energy and ressources are firmly concentrated on the enemies - The Other Services! Nothing else matters!!

          "They" got all the names and such anyways:

          Adam 52 and Credas, it does beggar belief if you are a civilian. Frankly, this kind of opsec fail occurs regularly. Yes, the military does know how to do opsec, just look at the heat-map there. However, if you read the Washington Post article [https://www.washingtonpost.com/world/a-map-showing-the-users-of-fitness-devices-lets-the-world-see-where-us-soldiers-are-and-what-they-are-doing/2018/01/28/86915662-0441-11e8-aa61-f3391373867e_story.html?hpid=hp_hp-top-table-main_strava-415pm%3Ahomepage%2Fstory&utm_term=.a7e90c1ca729], you'll find out that use was encouraged. I got the number off freebies wrong by a factor of ten (2,500 not 25,000), usually don't make errors of magnitude but it was late here and meds kicking in.

          Any remember the flash drives with confidential files still on them sold in an Afgani bazaar? Sh*t happens and still, to this day, seeding flash drives in a parking lot is a fave for pentesters.

    What benefit is it to Strava to make this information public? I don't understand why they would do this unless they've also sold it to someone to use for advertising bicycle and running stuff on routes popular with people that exercise.

      It's a cool thing, just as a work of art.

      It's a nice little way to boast about the scope of their services.

      It's handy for traffic planners to see how runners/cyclists move about a city.

      I tend to use it when going somewhere new to find out where the good cycling is, and I've used it to get off the bog of a bridleway I was on onto something decent.

        Fair points, also useful to advertisers though.

          A long time ago I tried to sell a dataset giving the demographics and rough volume of people passing particular sites (advertising billboards and retail sites, but it could have been anywhere). I had a few people interested but nobody actually bought it.

      There's no such thing as bad publicity*. Now all sorts of people who'd never heard of it before, know about Strava.

    Great news!

    In May 2015 many news sites carried a story that the silly Chinese army had banned it's forces wearing smartwatches and other 'wearable tech' - on security grounds. <sarcasm>Paranoia. It's clearly foolish to ban such useful kit.</sarcasm>

    2 1/2 years later and a company that tracks people through their kit publishes clear maps of where these people can be found and how frequently. Not only that but we can see where the people who are apparently most concerned about their physical fitness exercise around military and security facilities. Clearly the Chinese were not over-reacting.

    It would not surprise me if various state agencies had already issued regulations restricting the use of this kit - but as they didn't explain why, or enforce the regulation, it got ignored along with all the other apparently unnecessary cruft.

    I really hope that this becomes a much bigger news item. The world needs to understand that sharing any personal data without a damn good reason is an utterly foolish thing to do.

    Personal responsibility

    How about people have some?

    If you are sending data to the cloud, then think long and hard about whether it's a good idea and how private it is.

    Especially potentially personally identifiable data.

    .. from the strava users I know a lot of it is about "oneupmanship" e.g. showing off to others how quickly they completed cycling challenge x etc.

    Though I'm the sort of person where the only occasion I know how long a run took (time & distance) is when I do a park run (or similar) that is a known distance & my time is officially logged.

      Re: Personal responsibility

      Agree totally and work on the assumption that there is no such thing as anonymous data. Disparate event data from multiple interactions can be mined to identify sources or individuals. When you don't want to be tracked, turn your phone off and keep it in a Faraday cage.

    Strava is a fitness social application, it's explicitly for sharing ride/running/whatever data and it does a very good job of that. Yes, there are privacy issues. Each person must make their own decision about those.

    If you thought the heatmap was revealing, check out the Strava flyby feature: it identifies the other Strava users and their ride routes that you passed or were near on your own ride. It is brilliant even while it makes a mockery of personal privacy.

    Rules for location privacy / security

    1. Don't share location data.

    2. Don't post anything with location data.

    3. Don't collect location data.

    4. Don't enable location determination.

    Generally this will reduce your risks. Of course, someone else may tag you in a GPS marked photo...

      Re: Rules for location privacy / security

      That's a start.

      Then, turn off all unnecessary radios - WiFi, Bluetooth, NFC.

      Turn off data.

      If possible, turn on Airplane mode.

      As a bonus, your battery will last a lot longer, and your distraction level will drop.

      Anyone remember those productivity improvement methods that point out the advantages of handling calls and emails three times in the workday, and not otherwise?

    MIlitary Intelligence - A contradiction in terms.

    This is an app where users share their activity. They choose what data to place in the public domain so this is no revelation especially that this information and concern was raised over three years ago when police warned that users were leading thieves to their garden sheds, where they stored their expensive bicycles by not setting up privacy zones as many people also made their make and model of bike public.

    This by its own admission, a storm in a teacup given the Google Earth pictures. When there are Strava heat maps which tally with the secret blanked out areas Google Earth we can say that there is anything other than clickbait. Anybody that does not understand they are carrying around a tracking device in their pocket whether they have Strava installed, or their GPS even turned on must have been living in a cave for the last decade at least.

    Good practice in ICT for me has always been 'opt in' as the default. Fundamentally this is what people are doing when they accept T&Cs when they install an application. But who reads T&Cs or user manuals? Certainly not anyone who signs up as cannon fodder.
