I doubt there are gullible users will fall on this kind of fake cheap trick. Just always make sure that you are accessing from a legit yearn site. To make sure visit coingecko or coinmarketcap and access the website from there so anyone can ensure that they are dealing with the correct site. Dont use Google search engine, chances are that a fake website already above the real one and if you mistook it you'll end up being scammed.
The car engine on google is sometimes the real one is always below the fake and there are many examples that happen like the bustabit that was recently posted from this forum, so it's true you better search from Coingecko and Coinmarketcap for a safer one and I often do this so that not easily fooled by scamer.
Now Finance is always abused a lot, including in their domain project to make sure, even though in it they have infiltrated and are planning to extort your money so I think this needs accuracy so as not to access arbitrarily like what was caught by the OP.
