I work at Grab (SEA rideshare and licensed bank, but not licensed in VN).
A significant amount of fraud comes from scammers convincing victims to installed malicious apps. They fake being a customer service provider.
Banks don't want their customer's to lose their money and they don't have the tools to protect them from themselves. For all the privacy reasons, app stores don't even banks enough tools to identify and block this fraud.
Tricking someone into installing a malicious app usually doesn't involve them having a third-party or modified operating system on their phone. I'm asking about that because I believe it's a hypothetical risk rather than a problem in practice and I'm curious about any evidence to the contrary.
Drivers buy modified versions of our mobile app, because they think it will give them advantages over other drivers. These apps are side-loaded (not published in the app store).
Thanks for the additional detail. Do those apps actually give them advantages, or are they scams/malware?
I wasn't asking about sideloading apps though. I was asking about modified operating systems like LineageOS and GrapheneOS, or root via OS modifications like Magisk and KernelSU.
