How to Stop Spam Calendar Invites from Hijacking Your Phone

If your phone's calendar is suddenly flooded with terrifying alerts warning you about "Critical Security Breaches," "Viruses Detected," or "Guaranteed Prize Wins," do not panic. Your phone has not been hacked. You have simply fallen victim to a highly common, annoying trick where a rogue website stealthily subscribed you to a spam calendar feed.

These spam events are designed to look like system warnings to trick you into clicking malicious links. Fortunately, cleaning up this digital mess and securing your calendar takes less than five minutes. Here is how to reclaim your peace of mind.

For iPhone Users: Remove the Subscribed Calendar

Apple devices are the most common targets for this exploit. Depending on your version of iOS, follow these quick steps to delete the rogue subscription:

• Method 1: Directly through the Calendar App (iOS 14 and newer)
• Open your Calendar app.
• Tap the Calendars button at the bottom-center of the screen.
• Look for a section labeled Subscribed or Other. Find the suspicious calendar (it might have an odd name like "Click to Clean Your Device" or a random string of letters).
• Tap the red "i" icon (Info button) next to the spam calendar.
• Scroll to the bottom of the screen and tap Delete Calendar.

• Method 2: Through iPhone Settings (Older iOS Versions)
• Open your iPhone Settings app.
• Scroll down and tap Calendar, then tap Accounts. (If you are on an older iOS version, go to Settings > Passwords & Accounts > Subscribed Calendars).
• Look for any account that you do not recognize.
• Tap the suspicious account and select Delete Account.

For Google Calendar Users: Stop Auto-Add Invitations

If you are seeing spam invitations on an Android device or through your Google account, spammers are likely exploiting a feature that automatically adds emailed invites to your schedule. Here is how to disable it:

• Step 1: Adjust Event Settings
• Open Google Calendar on a desktop web browser (this is much easier than using the mobile app settings).
• Click the Gear icon in the top-right corner and select Settings.
• In the left-hand menu, click on General, then select Event settings.
• Look for the option labeled Add invitations to my calendar.
• Change this setting from "From everyone" to "Only if the sender is known" or "When I respond to the invitation in email". This prevents random strangers from injecting events onto your screen.

• Step 2: Turn Off Gmail Integration
• While still in the settings menu, click on Events from Gmail in the left sidebar.
• Uncheck the box that says Automatically add events from Gmail to my calendar.
• Click OK on the warning prompt to confirm the changes.

How to Prevent Future Calendar Hijacks

Now that your calendar is clean, protect yourself from future spam with these simple digital hygiene habits:

• Avoid suspicious pop-ups: When browsing the web, if a pop-up asks you to click "OK," "Allow," or "Subscribe" to view content, close the tab immediately. Spammers often disguise calendar subscriptions as fake CAPTCHA verifications.
• Never click links inside spam events: If a spam event does slip through, do not click any links or tap any phone numbers inside the description. This only confirms to the spammers that your email address is active.
• Report as junk: On Apple devices, if you receive a calendar invite from an unknown sender, tap Report Junk at the bottom of the invitation instead of selecting "Accept," "Maybe," or "Decline."
