Some people will not listen. It is as simple as download the Binance app from the official website. All exchanges also works like that. If you access the exchanges on the web, you will see where you can download their apps when you are about to login. All these are easy to avoid but some people are just novice.
Some people aren't well versed with technology, some even don't understand differences between domain which usually used by scammer to trick people.
so it's understandable that some people might fall victim.
I personally think using mobile app that we can get from play store or app store to be more assuring, as there's extensive review toward the app available in that market.
even nowadays I don't really trust any ads or clicking any ads available in site like google, I've seen some scam site advertising and trying to impersonate as a legitimate website.
I think for newbie, always be sure to recheck the domain, using adblocker and protection from antivirus software (the reliable ones) might help since sometime they also offer protection to filter scam site.
