Microsoft Forms is an app that enables web and mobile users to create surveys, polls, and quizzes for collecting feedback and data online. Microsoft Forms detects phishing attempts with the help of proactive phishing detection. It uses automated machine reviews to “proactively detect malicious password collection in forms and surveys”” to block phishers from abusing Microsoft Forms to create phishing landing pages. Microsoft is now working on also adding these phishing activity alerts to the Security and Compliance Center’s Alert center. It will also begin notifying Microsoft Defender for Office 365 users of suspected nation-state hacking activity detected within their tenants.”
