If you have an excess of events and invitations in your calendar app, you might think that you’re yet another victim of the so-called iPhone calendar virus

Here’s what exactly that means, how the messages ended up on your calendar, and how to get rid of the iPhone calendar virus

iPhone Calendar Virus 2022: Where Does iPhone Get the Calendar Virus From?

The iPhone Calendar “virus” is not technically a virus.

It’s a phishing scam where iPhone users are tricked into subscribing to a calendar, which then adds bogus events and deceptive invites to their Calendar app.

In most cases, clicking on any of these spammy calendar messages results in downloading different types of malware onto your device. Sometimes, these links can take you to shady websites that may steal your information. 

But how did you end up with a subscription to a calendar– without knowing- in the first place? 

You Accidentally Clicked on Fake Captchas

Captchas are those little puzzles that pop up when you visit a website and have to solve to prove you are not a bot.

Scam websites often display fake captchas. Clicking OK or checking the “I’m not a robot” box triggers a prompt to subscribe to the calendar, which gives bad actors a green light to fill your calendar with suspicious links.

The pop-up usually looks like the one below.

The Spammer Knows Your Email Address

If you enter the email that’s connected to your calendar app on a dubious website that sells information to third parties for profit or a company that holds your email suffers a data breach, spammers can get hold of your information and use it to their advantage.

In this particular case, it means sending fake invites and events to your calendar app.

Worth noting: As long as you didn’t click on the spam messages, you’re unlikely to end up with a virus on your device. If you think you did, here’s how to check for viruses on your iPhone.

Getting rid of iOS calendar spam is very straightforward. There are two main ways to do that.
