But the question is, how can I install uBlock Origin knowing I got the official version and not a malware infested one.

You can follow ublock origin subreddit

You'd think that download links would be prominently feautured on subreddit, but its not the case: https://www.reddit.com/r/uBlockOrigin/

The official "home" of uBlock Origin is the GitHub repo[1], you will find all the correct information there.
