Microsoft Teams: Invite attendees to register

🚨 The Signal: Teams event organizers can now invite specific users or groups to register for an event. This improves event management but introduces a new vector for targeted social engineering if not managed carefully.

The Impact

Event organizers and attendees are affected, with a low risk of targeted phishing if event creation is not properly governed.

• Event Organizers: New feature to manage invitations, requires awareness of potential misuse.
• Attendees: May receive targeted registration invites, increasing susceptibility to phishing if source is spoofed.

The Action

1. Review and update internal policies for creating and managing Microsoft Teams events.
2. Educate event organizers on verifying legitimate event registration requests.
3. Educate end-users on identifying suspicious event invitations and reporting them.
