Lessen also the downloading of non sense apps. If you don't need the app then don't download it. What typically happens is that whenever they see an interesting app and it says they can earn from it, they'll download it without thinking and research.
scammers and cyber criminals are reluctant to target apps that do not get traffic and many downloads(that doesn't mean they don't), there is more risk in the most popular apps and websites, sites they know alot of people use and many new people try to dowmload everyday. Just like the situation with zoom few weeks ago, it became a target because of the number of people using the app increased.(the more valuable an app or website is, scammers try to impersonate it more)
The thing about zoom is different, it's not a fake app but they've been hacked, hackers stole credentials.
Unlike these fake and scam apps, they're really made to scam people. But we can compare another incident to zoom hacking and that's when some of the YouTube channels get hacked and streamed scam giveaways.
