According to the report, the attackers impersonated an acquaintance of the recipient sending out an email with a subject line resembling an instant messaging notification, announcing new activity on the platform.

This way, the attackers emailed between 15,000 and 50,000 Teams members, trying to catch their attention and make them hit the Reply in Teams button.

The body of the email included what appeared to be an instant messenger box linked to a particular workgroup, a request, and the Reply in Teams button.

Clicking on any of these led to a fake Microsoft login page. The phishing page asked the recipient to enter their email and password.

In case the recipient went along with the request, the attackers could get their credentials or any personal information stored on the respective account.
