iPhone hack. I think my iPhone may have been hacked, what can I do??

I think my I phone 8 has been hacked. I keep getting messages about malware, security alerts and that my phone will be locked.

I have not opened any of these messages and clicked anything. Most of the messages do not have the apple logo. Any suggestions?

Please refer to Delete spam calendars and events on iPhone - Apple Support for Calendar Spam removal.

If running iOS 13 or earlier versions, check: Settings - Passwords & Accounts - Accounts - Any rogue entries here? If so, delete the rogue account. 

If running iOS 14, check: Settings - Calendar - Accounts - Any rogue entries here? If so, delete the rogue account. 

The Apple support article is below.

It means you have accepted an offer from some garbage website to “Allow Notifications”. Use the link posted above for steps to remove.

If the messages are appearing in the calendar, see above. Otherwise close the offending page and avoid sites that are involved in such bogus advertising tactics.

1000s of calendar invites just popped up on my iPhone saying different things about possible iPhone malfunctions and potential spyware needed. I think my iPhone has been hacked. What do I do?

thank you this happened to me
