XAMPP blocked

[shmool]

Hi,
I've just installed the latest version of XAMPP - 7.2.7 from the apachefriends website.
I'm trying to run it, but I get an alert saying "identity of the developer cannot be confirmed" and it doesn't let me open the app.
When clicking on the ? icon there's a further explanation saying "The app has been modified or damaged".
I know I can go to "Security & Privacy" and choose "Open Anyway", but I'm actually concerned whether I have the right version and not a hacked one...

How can I verify that I have the correct version? Is there another way do get XAMPP which is verified?
I'm using macOS High Sierra.

Thanks!
