If you have an iPhone or an iPad, it is more than likely that these days you have received an invitation to strange events sent by a stranger. What is happening is that the iOS Calendar app is suffering from a massive spam attack These invitations include links to different pages, which are being promoted in an unethical way.
Apple appears to be working on fixing the issue, which has been going on for a week. In principle, it is not normal for an app like Calendar to receive spam, so perhaps the apple brand did not have mechanisms to avoid it. At least, in the application interface there are no options to limit unwanted invitations.
It's true that iOS 10 has received many improvements, but the Calendar app is vulnerable to these spam attacks. Although the solution to the problem involves the implementation of a filter by Apple, users can remove notifications. Of course, it is not a good idea to indicate that we are not going to an event, as this will confirm that we have seen it, and we may receive more spam.
But we can remove notifications (for any event, not just spam) from iCloud web. In the advanced settings we have the possibility that invitations reach us to an email account of our choice instead of to the app.
It seems that Apple is experiencing a bad week, because we recently learned of a bug in iOS 10.1.1 is seriously affecting iPhone batteries. Spam in iOS Calendar can be fixed, of course, but millions of users have already been invited to events we care about, a considerable nuisance. Probably, for those who have carried out this action, the spam campaign has been profitable.
Apple is working on resolving this issue by blocking suspicious senders, though it hasn't provided many details. Of course, you should be careful with security, because spam seems to be able to sneak into even a simple calendar.
What do you think of this news? Have you received any messages in iOS Calendar that could be classified as spam?
