It has been reported that an event that you do not remember is added to the iPhone's "Calendar" app, and messages such as "Infected with a virus" and "iPhone is not protected" are displayed.
This is also a type of phishing scam, and IPA (Information-technology Promotion Agency) has received about 0 to 9 consultations a month between January and June 2020. However, since the beginning of July, the number has suddenly increased to 55.
The only way to add an event to someone else's calendar is to exploit a feature in the calendar.
For example, use the "Attendance Request Function" to create an event with the title "iPhone is not protected", enter the URL of the website in the URL field, and then enter the target email address in "Attendees". And add. Then, the notification will be sent to the user with that email address, and the event will be displayed on the calendar.
An event was added from an unknown person. The event "iPhone is not protected." Is automatically entered.The attendance request function is normally used to invite colleagues and acquaintances to a meeting or event. However, cybercriminals abuse this.
The purpose is to threaten to open it with a title and click on the URL. Of course, the websites displayed will be pages of online scams such as phishing scams and support scams.
Open the event details and you will see the URLIf you tap "Absent", the event will disappear, but cybercriminals will also be informed. In other words, it is revealed that it is a valid email address. There is a possibility that the number of online fraudulent emails will increase in the future.
What's more, this invitation event cannot be deleted in the usual way. Therefore, let's use the trick.
First, create an iCloud calendar with a name such as "spam". Next, open the "Calendar" settings for the event that the invitation came in and change it to the "Spam" calendar. Then hide the "spam" calendar and the event itself will disappear. It is also possible to delete the attendance request schedule for each added "spam" calendar.
Create and move a "spam" calendar when you receive fake event notificationsCyber criminals may also share the entire calendar. At that time, if you make the calendar name etc. arrogant, some people will press "Join the calendar" because of fear.
If you press "Join Calendar", you can delete it by opening the edit screen from the calendar list and tapping "Delete Calendar".
I get a message when I share my calendar. I'm asked to join the calendar. A lot of events are displayed. Tap "Delete calendar" to delete it.In addition, when browsing suspicious websites on iPhone, notifications such as "Add inquiry for calendar" ○○ "" may be displayed. If you press "OK" here, the calendar will be imported and a fake warning appointment will be displayed on the calendar. If you have imported the calendar, open "Calendar inquired" from "Calendar"-> "Account" in "Settings" and tap "Delete account" to deal with it.
These damages can occur if your email address is leaked, but once it's leaked, it's difficult to prevent. First of all, it is important that you never open the URL even if this kind of phenomenon occurs. If you open it, you won't be hurt if you close your web browser immediately.
You may be surprised if your calendar is suddenly filled with warnings. However, the only way to prevent the damage from spreading is to defend yourself.Keep in mind that it's okay to remove such scams without hassle.
