Hack message

Your phone hasn't been breached, this is just a scam pop up designed to scare you into doing something you shouldn't.

Was it a calendar style message? If so:

If you have iOS 13 or earlier versions, check: Settings - Passwords & Accounts - Accounts - Check for any accounts that you don't recognise - remove them if there are.

If you have iOS 14, check: Settings - Calendar - Accounts - Check for any accounts that you don't recognise - remove them if there are.

Hello @humza49,

Next time this kind of ennoying scam happen to you, just double click on the home button.

This will permit you to see from which application the false warning is coming from.

And next swipe up the window of the application so as to exit it without letting it do anything.

The truth is:

• virus are rather hard to conceive on iOS and would need high priviledge, this is the reason Apple is very reluctant to let anyone sell an anti-virus on the AppStore,
• virus for iOS do exist,
• there are many other way than viruses to steal you personnal information, for example: phone number, physical address, E-mail…

⇒ you are plain right to worry about what you see on your iPhone.

The people who are dangerous ( for themselves ) are the one who don't worry just because they have an iPhone.
