No surprise to see a number of weather apps on here. Seems to be such an incredibly scummy category. The built in Apple app is fine for basic information. There are plenty of high-quality third-party apps. Weather Line (my fav) is $2. DarkSky is $4. Instead people go for these weird free apps covered in ads with terrible UIs. The NOAA one isn’t made by the government, seems like using that name should be some kind of…

It doesn't necessarily follow that because an app is free that it has a higher probability of being malicious. If anything developers will introduce malicious code into paid apps because those types of users typically have money in their iTunes account and are more interesting / have a better list of credentials to steal than 'freeloader' type users.

On the flip side, the market prices for most of these tracked data are not very high. It's only lucrative to sell this data if you have a very large user base. For paid apps with smaller user bases, the incremental revenue is likely negligible.

Weather channel. Powers iOS built-in weather, and fetching actual weather data = sending exact user location every hour.

I have no idea why Apple allows this (the whole point of making Apple maps was to stop google tracking iOS users and here a service is getting everything).

(And Android - try to find an android phone where a default always on weather widget isn't preloaded on homescreen.)

How do researchers find this information? Presumably the apps are using encrypted network connections to submit your location data to surveillance backends. Is guardianapp reversing each application using jail broken devices? Using an iOS emulator to inspect the running app?

Lots of ways 1. You can inspect HTTPS traffic by installing a trusted MITM cert on your device - no jailbreaking necessary. 2. You can inspect the libraries provided by the owners of tracking endpoints to see what they collect and transfer. 3. Decompiling app bundles is usually pretty effective, and you can download them straight from iTunes.

I’m having difficulty installing a MITM cert on my iPhone 7. Does anyone have advice or can recommend some literature to do so?

The company I work for was acquired by a Chinese giant. Recently they sent us a static lib (i.e. no source available) to include in our app for “fraud detection”. We complied.

You didn't ask what it was or where it came from?

I’ve asked, but my concerns were taken as a joke, because in the past I’ve constantly been complaining about our data collection practices. I was objecting when the marketig team pushed in the AppsFlyer SDK, then the Branch.io SDK, then the Google AdMob SDK, then the MoPub SDK, then the ComScore SDK, then the Saasquatch SDK, then the Kahuna SDK. The Facebook SDK is included too, of course.

So after all this complaining over the years, they became kinda immune to my concerns, and when the Chinese handed down their blob they merrily went on with it.

Earlier quoted context omitted.

If I buy that phone, and I get a weather app… it’s going to need to know where I am to provide me the forecast. And once I give it that permission, how does the phone/OS prevent them from selling the data that I gave them permission to have? It doesn’t.

> it’s going to need to know where I am to provide me the forecast Why would you think that? I don't need to give a weather app my location. It only needs to have one or more locations of interest to me. My weather widget pulls multiple locations for me, and has no access to my location data.

So, if I don't give it my location, how does it give me the weather at my location?

Making a configuration profile that contains your custom root CA is the easiest way to go.
