Make sure the checksum matches when downloading from unofficial sources:

It is not an unofficial source.
To be more specific: If I'd uploaded the file myself to a third party file sharing service or sent it through a private message, it would be an "unofficial source". The `Archive.org` Wayback Machine does not function like that, meaning that I have not uploaded the file, but it's rather scraped from the original site by their web scraping bots. But in either case using a hash for integrity verification would only be useful if the hash's value was acquired from the original website. Since a third party can tamper with the file and then also give the new hash as the correct hash. And since the original website never provided hashes for integrity verification, the hashes provided by others (me included) will all be considered unofficial hashes.
But apart from all of this, in the grand scheme of things, hashes are not the best tools to utilize for tamper-resistance. Digital signatures are. Hashes are mostly used to verify the integrity of the file from a correctness perspective (that it wasn't corrupted during the download process), not from a security perspective.
