In recent weeks, a significant uptick in spam events infiltrating Apple Calendar has been observed, with the majority linked to cryptocurrency scams. This resurgence echoes previous instances from nearly a decade ago when Apple Calendar spam became a widespread issue, prompting the company to implement measures aimed at mitigating such intrusions.
Historical Context and Apple’s Response
The phenomenon of calendar spam isn’t new. Around 2016, users began reporting unsolicited calendar invitations, often containing malicious links or fraudulent offers. In response, Apple introduced features like the Report Junk option on iCloud.com to help users flag and remove unwanted events. Additionally, Apple released instructional content detailing steps to unsubscribe from spam calendars and adjust settings to prevent future occurrences.
Current Surge and Its Implications
Despite these efforts, the current wave of calendar spam appears to be more sophisticated and pervasive. Spammers are leveraging the calendar’s invitation feature to send events embedded with links leading to cryptocurrency scams. These invitations often bypass traditional email filters, making them particularly insidious. Moreover, interacting with these invitations—such as declining them—can inadvertently notify spammers of an active account, potentially leading to an increase in spam.
Understanding the Mechanism of Calendar Spam
Calendar spam exploits the open nature of calendar invitations. By obtaining a user’s email address, spammers can send unsolicited event invitations that automatically appear in the recipient’s calendar. These events often contain links or attachments designed to install malware or steal personal information. The urgency and legitimacy conveyed by calendar notifications can trick users into interacting with these malicious events.
Protective Measures Against Calendar Spam
To safeguard against calendar spam, users can adopt several strategies:
1. Disable Auto-Accept for Calendar Invitations: Adjust settings to prevent automatic addition of events to your calendar. This can be done by navigating to iCloud.com, accessing the Calendar app, clicking on the Settings gear icon, selecting Preferences, and under the Advanced tab, choosing to receive event invitations as emails rather than in-app notifications.

2. Delete Suspicious Events Without Interaction: If an unsolicited event appears, delete it without responding. Interacting with the event can signal to spammers that your account is active. On iOS devices, open the Calendar app, select the unwanted event, and choose Delete Event. ([rd.com](https://www.rd.com/article/iphone-calendar-spam/?utm_source=openai))
