Is anybody else upset that people are actively making up stories to prop up Apple on HN? Most of what you said is misleading or false:

> Here in Thailand banking apps fraud is rampant

Citation needed (on the "rampant" part).

> Most of the cases are found to be on android devices

Even if it's true most of the phones in Thailand are Android.

> clicking some link that installs some app

Not possible the way you describe it. You need to go through several system screens and popups to install a third party apk file from browser.

> takes control or mobile banking and transfers money from their account

As an app developer I can say, this is probably false. There is no API to do anything like that. Unless we are talking about a 0 day exploit, like iPhone NSO exploits. In that case you need to provide a source.

Let's check your source https://www.nationthailand.com/thailand/general/40024972

They are sending detailed instructions to victims on how to install screen recording apps. Users are always warned if their screen is being recorded on both Android and iOS, sideloaded or not. It's a matter of false trust, not sideloading. It's a phishing attack, those people would fall victim in any OS.
