If so, don't worry, you're not alone: calendar spam has become one of the most common annoyances for iPhone users, especially in recent years, and it's as annoying as it is easy to solve if you know how.
Although Apple implements measures to protect you, sometimes hackers and cybercriminals manage to bypass them through techniques that trick the user into subscribing to unwanted calendars.Learning to identify these threats and properly remove them will prevent other spam attempts from sneaking into your calendar again. Here's the most comprehensive and up-to-date guide to understanding how this spam gets into your iOS calendar and what steps to take to remove it and protect yourself in the future.
Why do spam events appear in the iPhone calendar?
iPhone calendar spam is not a virus as such, but exploits an inherent vulnerability in the way Apple allows you to receive calendar invitations from anyone, regardless of whether you have it in your contacts or not. This makes it easy for anyone who knows your Apple-linked email address, or even just browsing suspicious websites, to send you invitations that, if you accept them (sometimes unwittingly), end up signing you up for a calendar full of annoying appointments.
Invitations are often disguised as security alerts, prizes, discounts, or urgent notices to grab your attention.Have you heard messages like "Your iPhone has a virus!" or "Click here to protect your device"? These are typical examples of this type of event. In many cases, simply clicking a link or accepting a pop-up request on a website is enough to subscribe to that spam calendar, which will then reach all the devices associated with your Apple account.
How calendar spam works on the iPhone
iPhone calendar spam is actually a form of social engineering. that exploits user trust and the device's default settings. These are the main ways an unwanted calendar can sneak onto your iPhone:
- Leaked email address: If your email address is leaked (either through a security breach or by entering it on untrusted sites), spammers can send you calendar subscriptions.
- Deceptive pop-ups: Often, when browsing the Internet, fake pop-ups or captchas appear asking you to confirm actions or subscribe to services. Simply clicking "Accept" without looking closely can sign you up for a spam calendar.
- Links in text messages or email: Phishing attacks also come via SMS or email, inviting you to follow a link. These can automatically add you to an unwanted calendar.
- Third Party Applications: Installing unofficial or poorly reviewed apps can also lead to automatic calendar subscriptions.
