Your iPhone calendar used to remind you about dentist appointments and dinner reservations.
Now? It might be screaming that you’ve “won a prize” — or worse, that your device is infected and your bank account is toast.
Welcome to the latest digital headache: a calendar con that’s turning Apple users’ schedules into spam central, per Newsweek.
Cybercrooks have figured out a sneaky way to blast iPhones and iPads with bogus alerts — no shady app download required.
Instead of slipping malware onto your device, scammers trick users into unknowingly subscribing to rogue calendars. Once you’re in, they’ve got a direct line to your lock screen.
The result? A flood of fake event invites and notifications urging you to click urgent “security warnings,” claim mystery rewards, or call sketchy phone numbers.
It’s less “Meeting at 3 p.m.” and more “Your iPhone has been compromised!”
The kicker: the alerts can look oddly official. That’s because calendar subscriptions don’t pass through the App Store’s usual security checkpoints.
As one Reddit user recently wrote about their dilemma: “All of the sudden, my calendar app has been doing these random events which I cannot remove or disable. New ones replace them over time.”
While you may think Apple is tapping you on the shoulder, it’s actually a scammer sliding into your schedule.
Security pros say the trap is often sprung with a single careless click — usually on a dodgy pop-up or spammy link.
Tap the wrong box and, voilà, you’ve subscribed to a hidden calendar that starts carpet-bombing your phone with junk.
The good news? It’s annoying — but not the end of the world.
First things first: Apple does not send virus alerts through its calendar app. If your calendar claims your phone is infected or that you’ve hit the jackpot, assume it’s fiction worthy of a sci-fi series.
To shut it down, head to your settings and check your calendar accounts for any “subscribed calendars” you don’t recognize.
If something looks suspicious — random name, strange email, anything you didn’t knowingly sign up for — delete it. That usually stops the madness.
You can also open the calendar app itself, dig into the list of calendars, and boot any mystery subscriptions from there.
Some savvy users recommend blocking the sender’s associated email address through the mail app for extra peace of mind.
“You clicked on something that subscribed you to a calendar that is giving you alarming pop-ups multiple times a day, trying to scare you into paying for something or giving information,” one wrote in response to another user on social media dealing with this issue.
“Tap on one of the events and hit ‘unsubscribe from calendar,’” they added.
If ghost events are still haunting your schedule after you unsubscribe, you may need to manually delete lingering invites.
Annoying? Yes. Permanent? No.
“I had this too,” someone else wrote in the same Reddit thread.
“Check your spam folder for these same mail subjects. I don’t know why/how they get added in my calendar if I didn’t accept any invitation,” they continued. “My solution was to stop syncing my Outlook/Hotmail to my phone calendar. I was not using it anyway.”
This tactic is spreading as scammers hunt for new ways around tighter app-store defenses.
Instead of hacking your phone, they’re hacking your habits — banking on curiosity and panic to do the dirty work.
The rule of thumb: don’t click on calendar alerts about prizes you didn’t enter, viruses you didn’t suspect or “urgent” problems you didn’t cause. And if something feels off, it probably is.
Your iPhone should be keeping track of brunch plans — not broadcasting cyber nonsense. If your calendar starts acting like a carnival barker, it’s time to show those crooks the door.
