New Hack Targeting Australian Users: Calendar Invites Disguised as Microsoft Notices

Recently, a new phishing tactic has emerged, involving fake calendar invitations that appear to be sent from Microsoft Billing activation.team@team.microsoft.com. However, these invites actually originate from random, unverified email addresses, often sent “on behalf of” others to exploit trust in familiar brands.

These fraudulent invitations are designed to:

  1. Trick users into clicking on malicious links
  2. Harvest personal or financial information
  3. Install malware or ransomware on devices

Why is this dangerous?

Unlike traditional emails, these invites can bypass many standard email security filters and land directly in users’ calendars, appearing legitimate and urgent.

Recommended Action:

  • Delete the calendar invite immediately
  • Mark the sender as spam
  • Do not click on any links or respond to the event
