Microsoft Teams Calling Adds Protection Against Brand Impersonation
Microsoft is rolling out a new Teams Calling feature that warns users about suspicious inbound VoIP calls from external parties potentially impersonating trusted brands.
Microsoft is introducing a new security feature for Teams Calling designed to combat brand impersonation. The update will provide users with warnings when they receive inbound VoIP calls from external callers who have not previously contacted them and who may be attempting to impersonate trusted organizations.
This functionality aims to reduce the success rate of social engineering attacks that leverage the perceived legitimacy of Microsoft Teams to deceive employees. By flagging suspicious first-time callers, the feature provides an additional layer of verification for users who might otherwise trust an incoming call based on the platform's professional context.
The move reflects a broader industry effort to secure communication platforms against sophisticated phishing and impersonation tactics. Users should remain vigilant and verify the identity of callers through secondary channels when receiving unexpected requests, even if the platform provides a warning. Help Net Security, [Microsoft]
