How do I verify and respond to a hacking alert on my iPhone?

If a page like that pops up, it is a scam. There is nothing on the iPhone that would report that you have been hacked, and for your phone to be hacked would require someone to have possession of your device for an extended period of time and your Apple account and password. These things pop up all the time from groups that are looking for a way to make money off of you. It probably wanted to get you to purchase an app or other service to get rid of the problem. The best way to get rid of it is to ignore and close it.

Thank you! How would I know in the future?

There is never going to any message popped up on your screen that is provided by Apple and says your phone has been hacked. EVERY such message is meant to scare you into calling a number to reveal personal information to the scammer or click a link to download some software that claims to protect you. There is no action that you need to take as long as you did not give the scammer any information.

I am actually surprised that is the first time you have seen a scam message such as that pop up. You do not see them on legitimate websites, but once you start venturing into the grey areas of the internet, either from a search link or link found on Social Media, you see them quite frequently.

It isn't. It is a scam. Something that is allowed by a web page. Stay away from the web page and you should be alright. You did right by not clicking on the link.

How would you know? Messages like that are always from scammers.
