    A bit skeptical of how this article is written as it seems to be mostly written by AI. Out of curiosity, I downloaded the app and it doesn't request location permissions anywhere, despite the claims in the article.

    I've noticed Claude Code is happy to decompile APKs for you but isn't very good at doing reachability analysis or figuring out complex control flows. It will treat completely dead code as important as a commonly invoked function.

    • Groxx 14 minutes ago
      The permissions snippet they show also doesn't include location, and you can't request location at runtime at all without declaring it there.

      I'd verify all this stuff for myself, but Play won't install it in my phone so I can't really get the APK. Maybe because I use Graphene...? but I don't know all the ways they can restrict it, maybe it's something else (though for a pixel 9a it's rather strange if it's hardware based).

      The article does not claim the app requests the location. It claims it can do it with a single JS call.

      • esprehn 22 minutes ago
        It can request with a JS call. It can't passively collect it without you approving first. The article is written like calling that JS function will turn on location tracking without consent.
        • mattdeboard 6 minutes ago
          He explicitly says he can't determine it, but that the location tracking as configured will turn on once the user grants consent. All true statements.

          How would you have written it differently

        so can ... any other code anywhere on a mobile device? That is how API work...

        • david_allison 18 minutes ago
          You need to state the permissions you *may* request/use in AndroidManifest.xml. This data can then be displayed to users pre-installation.

          From the (limited) article, it doesn't seem they do this: https://thereallo.dev/blog/decompiling-the-white-house-app#p...

          ----

          EDIT: I'm mistaken. From the Play Store[0] it has access to

          * approximate location (network-based)

          * precise location (GPS and network-based)

          [0] https://play.google.com/store/apps/details?id=gov.whitehouse...

          This seems to disagree with:

          > The location permissions aren't declared in the AndroidManifest but requested at runtime

          *shrug*, someone should dig deeper. It looks like the article may not match reality.

      what version are you on?

      from the iphone app store: version 47.0.1 - minor bug fixes - 34 minutes ago

      while the parent posted 18 minutes ago

      they may have patched the location stuff as part of the “minor bug fixes”?

      • filoleg 28 minutes ago
        I have the iOS version from yesterday, haven't updated the app yet.

        No location permission request prompting encountered. In system settings, where each app requesting location data is listed, it isn't present either.

  • SoftTalker 2 hours ago
    Looks like what you might expect in a standard marketing app from a consultancy. They probably hired someone to develop it, that shop used their standard app architecure which includes location tracking code and the other stuff.

    Interesting. The site is nearly unusable to me unfortunately. '19 MBP w/ Chrome - scrolling stutters really bad
    • tredre3 25 minutes ago
      Scrolling is extremely poorly behaved on that page for me too, Firefox 149 Windows 10. Which is quite ironic coming from an article that mainly criticizes the web dev aspects of the app!
    • imalerba 1 hour ago
      Scrolling is so laggy it's annoying to follow on mobile (FF 151.0a1)

    Are those references to 45 and 47 "Easter Eggs" to Trump's presidency number(s)? As in, forty-five-press (45th president) and Version 47.x.x (47th president), as well as the text message hotline (45470).

    The argument regarding no certificate pinning seems to miss that just because I might be on a network that MITM's TLS traffic doesn't mean my device trusts the random CA used by the proxy. I'd just get a TLS error, right?
    • thegagne 2 hours ago
      Not if you are part of an org that uses MDM and pushes their own CA to devices.
      • r4indeer 2 hours ago
        Ok, fair point. However, I would consider any MDM-enabled device fully "compromised" in the sense that the org can see and modify everything I do on it.
        • p2detar 1 hour ago
          An MDM orga cannot install a trusted CA on non-supervised (company owned) devices. By default on BYOD these are untrusted and require manual trust. It also cannot see everything on your device - certainly not your email, notes or files, or app data.

    > The official White House Android app has a cookie/paywall bypass injector, tracks your GPS every 4.5 minutes (9.5m when in background), and loads JavaScript from some guy's GitHub Pages (“lonelycpp” is acct, loads iframe viewer page).

    Doesn’t seem too crazy for a generic react native app but of course coming from the official US government, it’s pretty wide open to supply chain attacks. Oh and no one should be continually giving the government their location. Pretty crazy that the official government is injecting JavaScript into web views to override the cookie banners and consent forms - it is often part of providing legal consent to the website TOS. But legal consent is not their strong suit I guess.

    • trimethylpurine 2 hours ago
      Aren't the banners for EU page visitors. I don't think there is a US law about this, is there?
      • xocnad 1 hour ago
        And when the app links off to an EU site? Nothing prevents an EU user from using this app. There are a variety of Trump enthusiasts, though I suspect less than there are here in the US.

    So at least it does something actually beneficial for the user! I wish it could go even further, the way Reader Mode in a browser would go.

    nice work, so they can get your location and have ICE scoop you up if required

    lol honestly all of this tracks given the current administration. i'm actually surprised it isn't worse. but yeah, amateur hour for sure.

      "Amateur hour" is basically their theme. They were swept in on a wave of distrust for people who know what they're talking about. They were elected to tear down Chesterton's fence, even (and especially) the parts holding in the face-eating leopards.

      To mix the metaphors further, they (the politicians and their supporters) fancy themselves the kind to dream of things that never were and ask why not. Why not have a war in Iran? You won't know until you give it a try.

    "An official United States government app is injecting CSS and JavaScript into third-party websites to strip away their cookie consent dialogs, GDPR banners, login gates, and paywalls."

    In their defense, this is the first thing the Trump admin has done that's unambiguously positive for ordinary people.

    • subscribed 6 minutes ago
      Indeed.

      I'd love it somehow taken out of it and made available for the general public. Custom uBlock / Adblock filers will be probably the easiest.

    • ronsor 2 hours ago
      Yes, this is a major UX improvement considering I remove those with uBlock Origin anyway.

    Giving people a taste of web with Ublock Origin annoyance filters applied, refreshing. Can’t believe orange man regime is doing one thing right.

    Rare Trump administration W. I'm assuming there's one particular website they open in the app that shows a cookie popup, and this was a dev's heavy-handed way of making that go away.

    I don't see what the fuss is about. This all looks pretty standard. I use random people's stuff all the time. Isn't that the point of open source?

    Did you find something malicious in the random GitHub repo? If so, you should write an article about that instead.

    • kevinsync 1 hour ago
      Using somebody's stuff is different than hot-linking directly to a hosted version of it, even just from the perspective that dude could delete it at any time and break the whole app.
    • xocnad 1 hour ago
      All good for you to make those choices for yourself. Your response seems to be show ignorance of all the recent supply chain attacks that have occurred. You can imagine that given the situation with the shoe gifts that many high up members of the administration and cabinet members are running this app.
    • input_sh 56 minutes ago
      It's always a better idea to make a local copy of it.

      Imagine they're downloading a project directly from your GitHub account. Even if you're not doing anything malicious and have no intention of doing anything malicious even after you've been aware of this, now all of a sudden your GitHub account / email is a huge target for anyone that wants to do something malicious.

    • rendx 1 hour ago
      I don't know if you're being serious or not, but in case you are: There is a difference between (re)using other people's open sourced code, hopefully reviewed, and giving anyone in control of the third party repository the ability to run arbitrary code on your user's devices. Even if the "random GitHub repo" doesn't contain any malicious code right now, it may well contain some tomorrow.
    • rpdillon 54 minutes ago
      The dependencies weren't vendored, meaning their behavior can change at any time if a malicious actor gains control of that third-party repo.

      This is bad for security.

  • colesantiago 2 hours ago
    This is a pretty standard decomplation of an Android app.

    I am sure if you decompile other apps used by hundreds of thousands of people, you would find all sorts of tracking in there.

    Thanks for helping the White House improve their app security for free though.

    • yellow_lead 2 hours ago
      Even in the apps I've worked on, you won't find us loading arbitrary JS from a random GitHub user's account.

        You'd be surprised how many apps inside have hacks and workarounds because deadlines.

          Let's see if anyone can give an example of such a high profile app doing something similar.
          • flutas 1 hour ago
            I've worked on a three letter sports orgs (one of NFL, NBA, NHL, etc) Android app.

            I always joke that we could probably tell you what color and type your underwear is on any random day with how much data is siphoned off your phone.

            As for loading random JS, yeah also seen that done that before. "Partner A wants to integrate their SDK in our webviews." -> "Partner A" SDK is just loading a JS chunk in that can do whatever they want in webviews, including load more files.

            Don't get me started on the sports betting SDKs...

            Though we do have a Security team constantly scanning SDKs and the endpoints for changes in situations like this.

              Partner A is not random JS. The assumption there is 1) you have some official signed agreement with them and 2) you've done your due diligence to ensure you can use them in this way.

              It's not just some person's GH repo who can freely change that file to whatever they want.

              Hotlinking is as old as the internet, and a well-worn security threat.

    • rpdillon 53 minutes ago
      Nah, I suspect any app that's loading arbitrary JS from somebody's random GitHub page would get called out for that behavior. We're getting supply chain attacks daily.
