If you’re like most of us, your phone’s calendar is a trusty sidekick, reminding you about doctor’s appointments, grandkids’ birthdays, and the odd lunch date with friends.
But what if, instead of helpful reminders, your calendar suddenly started shouting about ‘urgent security warnings’, ‘prize wins’, or even threats that your bank account is in danger?

Unfortunately, this isn’t a plot from a new crime drama. It’s the latest scam targeting millions of iPhone users, and it’s catching people off guard, especially the most vulnerable, across Australia.
Let’s break down what’s happening, how these scammers are sneaking into your devices, and, most importantly, how you can kick them out for good.
What’s the Scam?
Unlike traditional scams that require you to download a dodgy app or click on a suspicious attachment, this new trick is sneakier. Cybercriminals have figured out how to flood your iPhone or iPad with fake calendar events and notifications without you ever installing anything.
Instead, they’re exploiting a lesser-known feature of your iPhone: calendar subscriptions. This usually happens when you accidentally tap on a suspicious pop-up or click a spammy link, often disguised as a prize notification, security alert, or some other urgent message.
With just one click, you’ve unknowingly given scammers a direct line to your calendar, and suddenly your phone is buzzing with bogus events. One social media user pointed out: ‘All of a sudden, my calendar app has been doing these random events which I cannot remove or disable. New ones replace them over time.’

It’s a sneaky tactic because calendar subscriptions don’t go through Apple’s usual App Store security checks. That means these spammy events can slip right onto your device, bypassing the protections you’d expect.
Why Is This So Dangerous?
These fake calendar events can look surprisingly official, and scammers can make their alerts look just like the real thing. You might see messages like ‘Your iPhone has been compromised!’ or ‘Claim your reward now!’, and all of this is designed to scare you or tempt you into clicking further.
Worse still, these notifications can appear right on your lock screen, making them hard to ignore. Some users have reported being unable to remove or disable the events, with new ones popping up as quickly as they delete the old.
The goal is simple: to get you to click on links, call dodgy phone numbers, or hand over personal information. Sometimes, they’ll try to convince you to pay for unnecessary ‘security services’ or trick you into revealing your bank details. It’s a classic case of social engineering, where they use fear and curiosity to manipulate you into making a mistake.
How to Spot a Scam Calendar Event
While these calendar scams are annoying and unsettling, they’re not the end of the world, and you can get rid of them without too much fuss. You can usually spot them because they use:
Unfamiliar senders
If you see calendar events from names or email addresses you don’t recognise, be suspicious.
Too-good-to-be-true offers
Be wary of messages about prizes, lotteries, or urgent warnings. These are almost always scams.
Pressure tactics
Anything urging you to act immediately, especially if it involves clicking a link or calling a number, should raise a red flag.

How to Remove a Scam Calendar From Your Device
Ready to reclaim your schedule? Here’s how to shut down the scam:
1. Check Your Calendar Subscriptions
- Go to your iPhone’s Settings.
- Scroll down and tap on ‘Calendar’.
- Tap ‘Accounts’.
- Look for any ‘Subscribed Calendars’ you don’t recognise. If you spot something suspicious, like a strange name or email, delete it.
2. Remove Rogue Calendars Directly
- Open the Calendar app.
- Tap ‘Calendars’ at the bottom.
- Find any unfamiliar and/or subscribed calendars.
- Tap the suspicious calendar and click ‘Delete’.
3. Block the Sender’s Email (Optional)
- If you know the email address sending the invites, you can block it in your Mail app for extra peace of mind.
4. Delete Lingering Events
- If some fake events are still hanging around, you may need to manually delete them from your calendar.
5. Review Your Email Sync Settings
- Some users have found that disabling calendar sync for unused email accounts (like old Hotmail or Outlook addresses) can help stop the spam.
Additionally, don’t click on suspicious links or pop-ups, especially those promising prizes or warning of urgent problems. And be wary of calendar invites from unknown sources. If you don’t know who it’s from, best to delete it entirely from your calendar.
What If You’re Still Stuck?
If you’ve tried everything and your calendar is still haunted by ghost events, don’t panic. You can always reach out to Apple Support for help, or visit your local Apple Store for hands-on assistance.
Key Takeaways
- Millions of iPhone users have fallen victim to a scam where fake calendar events flood their device with dodgy alerts and spam, even without downloading any sketchy apps.
- Scammers trick users into subscribing to rogue calendars, leading to constant fake notifications about supposed virus infections, prizes, or urgent warnings — none of which are legitimate messages from Apple.
- To fix the issue, users should head into their iPhone settings and calendar accounts, delete any suspicious or unknown ‘subscribed calendars’, and block associated email addresses if needed.
- Experts advise never clicking on strange calendar invites or pop-ups, as these are designed to fool you into giving up information or making payments — trust your gut if something seems off.
