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.

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).

--- EDIT ---

To be specific / add what I can check, this is what my Play Store "about -> permissions" is showing:

    Version 47.0.1 may request access to
    Other: 
      run at startup
      Google Play license check
      view network connections
      prevent phone from sleeping
      show notifications
      com.google.android.c2dm.permission.RECEIVE
      control vibration
      have full network access
which appears fairly normal, and does not include location, and I think Play includes runtime location requests there. Maybe there's a version-rollout happening, or device-type targeting?

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

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.

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

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.

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.

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.

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?

Not if someone can issue the certificate signed by the CA your phone trust.

Imagine being in a cafe nearby, say, embassy of the certain north African country known for pervasive and wide espionage actions, which decides to hijack traffic in this cafe.

Or imagine living in the country where almost all of the cabinet is literally (officially) being paid by the propaganda/lobbying body of such country.

Or living int he country where lawful surveillance can happen without the jury signoff, but at a while of any police officer.

Maybe its not common but frequent enough.

How would they get your phone to trust their CA? Connecting to a Wi-Fi network doesn’t change which CAs a device trusts.

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.

If it is untrusted, you also won’t have a TLS connection be established based on that CA.

> 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.

They conduct a pervasive, hidden, persistent user tracking not only without consent, looking at the analysis, but also stripping the user from a chance of declining tracking on other sites.

"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.

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

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.

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.

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.

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.
