Spam isn’t just in your email: How a rogue calendar invite could disrupt your workday

Cybersecurity experts are warning of a massive surge in 'calendar spam,' where malicious invites are used to phish for information or disrupt organizational workflows. The attacks have seen exponential growth, targeting both individual users and entire companies.
Why it matters
This trend represents a growing security vulnerability in common productivity tools, requiring increased user vigilance and better administrative controls.
KUALA LUMPUR, Sept 30 — It starts with getting a calendar invite for something you know you shouldn’t be getting, usually from a familiar name, most of the time, a colleague.
Then the invite that you didn’t even click “Yes” to has taken up space in your entire calendar.
If you’ve been unlucky enough to get your email in your Google Workspace it won’t just be you, but your colleagues as well.
Your boss, your juniors, even the cleaning lady now have their whole calendars full of this random invite.
This is the new phenomenon of spam calendar invites that can hijack your entire organisation’s calendars and even disrupt emails.
In most cases it’s an attempt at phishing, convincing you to try and join a meeting created especially to steal your information.
ZDNet reported that according to cybersecurity firm Sublime, these calendar-based attacks have seen a dramatic rise.
