alt Hacker NewsHonestly, if coerced sideloading is a real attack vector, then this seems to be a pretty fair compromise.
I just remain skeptical that this tactic is successful on modern Android, with all the settings and scare screens you need to go through in order to sideload an app and grant dangerous permissions.
I expect scammers will move to pre-packaged software with a bundled ADB client for Windows/Mac, then the flow is "enable developer options" -> "enable usb debugging" -> "install malware and grant permissions with one click over ADB". People with laptops are more lucrative targets anyway.

The scam only has to work on a tiny slice of users, and the people who fall for fake bank alerts or package texts will march through a pile of Android warnigns if the script is convincing enough. Once the operator gets them onto a PC, the whole thing gets easier because ADB turns it into a guided install instead of a phone-only sideload.
That's why I don't think the extra prompts matter much beyond raising attacker cost a bit. Google is patching the visible path while the scam just moves one hop sideways.

I don't believe that it is. I follow this "scene" pretty closely, and that means I read about successful scams all the time. They happen in huge numbers. Yet I have never encountered a reliable report of one that utilized a "sideloaded"[1] malicious app. Not once. Phishing email messages and web sites, sure. This change will not help counter those, though.
I don't even see what you could accomplish with a malicious app that you couldn't otherwise. I would certainly be interested to hear of any real world cases demonstrating the danger.
[1] When I was a kid, this was called "installing."
I predict that they're going to introduce further restrictions, but I think the restrictions will only apply to certain powerful Android permissions.
The use case they're trying to protect against is malware authors "coaching" users to install their app.
In November, they specifically called out anonymous malware apps with the permission to intercept text messages and phone calls (circumventing two-factor authentication). https://android-developers.googleblog.com/2025/11/android-de...
After today's announced policy goes into effect, it will be easier to coach users to install a Progressive Web App ("Installable Web Apps") than it will be to coach users to sideload a native Android app, even if the Android app has no permissions to do anything more than what an Installable Web App can do: make basic HTTPS requests and store some app-local data. (99% of apps need no more permissions than that!)
I think Google believes it should be easy to install a web app. It should be just as easy to sideload a native app with limited permissions. But it should be very hard/expensive for a malware author to anonymously distribute an app with the permission to intercept texts and calls.
