I don't think there is any list. But probably there isn't anything you could do besides researching a little bit before download files from any website.
e.g:
You want to download the Namecoin Core wallet. From coinmarketcap you can see that their official website is
https://www.namecoin.org/Now, if you want to be 100%, there is a lot of stuff you can search to make sure that's the official website.
- find their official thread on BitcoinTalk, and check if there is any indications that this their real website.
- find their official social medias - if any - (twitter, reddit, facebook...), and do your own check there.
- make a thread here asking for confirmation on the official url.
Besides, I don't think any fake website would do so much work to make sure someone falls for them. Most of the time, users only get scammed and fall for phising because they click on any link they find and download files/insert passwords without even doing a simple google search.
