Does GitHub or anyone checks those QT wallets before they`re being published?
Bitcoin Gold and so many other suspicious coins use QT wallet and now is the time to ask ourselves that if all QT wallets you download from GitHub are safe? Is it possible to hide some malicious code within those wallets you download from GitHub and damage your computer or other wallets somehow?
Can someone please give me some details about the security measures of GitHub?
Sure, it is possible that any compiled program is compromised and could be hosted on GitHub.
They way you trust a compiled software, is if it is cryptograpically signed by several trusteable people with PGP, or at least have some SHA256 checksum that you could use to verify, that hasn't been questioned by any of the developers.
You can always compile the program yourself, and if you can't be arsed to do that, get a secondary computer to install all these Bitcoin Gold Cash XT whatever wallets.
