Suspicious calendar invitations on iPhone

suspicious iOS calendar invitation

For a few days now I've been getting strange invitations every day in my iOS calendar on the iPhone. Some people who are completely unknown to me invite me to use their calendar. The exact wording then says, for example, "Use logic class?" "Mitchell William invited you to a shared calendar." Then I can "decline" or "share calendars". Since I do not know these people 100% and suspect some new maliciousness from spammers or scammers behind them, I always refused.

I get these suspicious invitations on the iOS calendar. Strange isn't it?

However, I would still be interested in what the intention is. And if it's a nasty scam, then it would be interesting to know how the calendar is exploited in the process. I could imagine that you might smuggle some appointments into the calendar, which in turn call up websites that distribute malicious code. This probably only works with jailbroken iPhones, but there are already quite a few of them. But that's just speculation.

At first I thought there should be more people who got these strange calendar invitations and I looked for the message in Google, but unfortunately I didn't find anything. Right now I seem to be the only one blogging about it. :-)

If there are more people receiving these invitations, I would appreciate your feedback!

    Hello, thank you for your blog first.
    This is exactly what I received today and
    was very surprised.

    Martina Kneis has invited you to a shared calendar.
    I would also have a screenshot.
    I have no idea what the intention is ...

    I received exactly the same invitation today.

    I wonder how you can block this permanently?

    Maybe you know how to do it?

    Greetings to Zulu

    Hello oh have already received this twice. Always rejected because I don't know the people. Tonight I even got an invitation to share photos (cloud).
    I would be interested in how I can stop the whole thing.

      Hello Bodo! Currently there is only one way against the photo invitation. You take a screenshot of the invitation and send it to
      Then the corresponding user is deleted. It is the same with the calendar invitation: You should also send the screenshot to Apple, but you shouldn't press any of the three buttons, because you can also "reject", verify the email and then continue to fill you with spam. Instead, you make a new calendar, slide the invitation in there and then delete the entire calendar. Then the invitation is gone without the other person receiving any feedback.

    Unfortunately I only found the blog after I filed the invitations several times! Can I still use the new calendar method the next time?

    • Sir Apfelot says:

      That's fine. As a rule, the spam invitations always come from different email addresses, so that each new invitation offers a "new chance" to take action against it.
