First of all, the URL contained in a message from a stranger (email, SMS/mms, iMessage) should never be tapped.As a general common sense, you don't invite unknown people who have suddenly visited to your house, and as well, the URL tap is synonymous with trusting the sender of the message, so easy taps are strictly prohibited.
It is extremely dangerous to trust a message from an unknown/unknown person.If the plausible content, for example, the URL is attached to the words that inform you of the absence of courier, the URL will be considered meaningful, but it may be a trap to bring out personal information.Hmm.Rather, if the message from an unknown person (phone number/email address) is almost certainly a trap.
In fact, there have been a series of cases where Apple IDs are extracted from the URL attached to the message of the courier.According to information on the Information Processing Agency, tapping a URL attached to an SMS that is sent to the iPhone user, it is induced to Apple's fake site, where Apple ID, password, and mobile phoneHe was asked information such as a phone number, and he seems to have been hijacked by accounts.
If your account is hijacked, you will be able to shop without permission with a registered credit card.If you enter your mobile phone number and authentication code, you may be shopping by carrier payment.The damaged Apple ID must be initialized, and the character of the game app that has been struggled to disappear will also disappear.
Fortunately, even if you tap the URL and be guided to a fake site, you will not be able to get any physical damage unless you enter anything, but it is still dangerous.Now that the cost of obtaining SSL certificates has declined, the website that has been converted to SSL (URL starts with "HTTPS") is not safe, so it is dangerous to distinguish it with the URL.Anyway, the URL sent from an unknown person is completely through, exhausted.
