Since the other reply was unhelpful: apps are supposed to have limited privileges and isolation from each other, yes… But the whole point of malware like this is that they figure out ways to break those restrictions and get escalated privileged.
You can get more technical detail from reading the report, in this case it looks like the app does not contain malware, but instead requests an update after install that contains the bad code and then breaks the app limitations and scans for the target banking applications and copies the security certificates.
It looks like they are doing it after app install malicious patch. This patch asks for SMS and accessibility access to gain privileges necessary to get into the banking apps. I haven’t thoroughly read it but just looking at the attack chain that’s what I gleaned.
He’s being condescending because he believes as a developer nothing is actually fully secure. If I spend 100 hours building and securing something, that’s not going to stack up very favorably vs the 1,000’s or even 1,000,000’s of hours attackers and communities can spend trying to break my security layers.
Basically, he’s a dick in how he answered the question, but the truth every software engineer learns, is that there is no fully secure system. There’s always an angle/attack vector you didn’t think of and secure.
Yes, the app doesn’t steal any information from other apps. The report says the malware just displays a fake bank login page, in the hope the user gives it their details willingly.
Aren’t apps on android hermetically sealed from other apps and malware. How could this be achieved ?

As a developer this question is hilarious to me
Explain yourself
please enlighten the rest of us
As a curious Android user this comment is useless to me
As an Android developer that comment makes me sad. Then I remind myself that Lemmy is full of people who migrated from Reddit.
Dude, do you not want people on this platform? Reddit migrants come with baggage yes but I’d rather that than the husk that was Lemmy before.
I’m not gonna scream back at you,… I’m just going to walk back… very… very… slowly…errrrrrrr
We each have our specialties, and it would be unreasonable to ask that everyone share yours.

Ugh, TIL zscaler actually does more than just send my PII to the USA without my consent.
and one day you’ll say why, right?
Why? They’re absolutely right. The article doesn’t say anything about a root exploit or phishing either so were left wondering…

Of course there are (or there can be) fully secure systems. The problems come when you assume something is.
