If there is a good reason to try and hack into someone’s Apple account it is because it contains a lot of sensitive data, such as devices associated with said account, phone numbers, contacts, photos, and also credit card details in which the hacker will be able to go on a shopping spree if they find out said details.
This is why it always pays to be careful about the emails you receive, although it should be noted that there is a new iTunes App Store phishing scam that is making its rounds. The email in question is related to subscription renewal emails, in which users receive an email claiming that they have purchased a subscription to a service, such as YouTube Red.
It will also show a ridiculous amount which presumably the idea is to shock users, whereby they will then click the “Cancel subscription” link which obviously does not take users to Apple’s website. Instead it takes users to another site where they will need to “confirm” their credit card details, which is how the hackers will be able to steal your information.
Those who do use Apple products and have an Apple ID will want to pay attention to the emails they’ve received. One way to check is to see the email of the sender, where it should be from an Apple.com account. Another way is to hover your mouse over the link to see what website it takes you to, and if it’s somewhere you don’t recognize, you’ll probably be better off not clicking it.
