Microsoft Defender SmartScreen Edge marked our site as phishing site

Question

Our domain, vstbalance.com, was flagged as phishing by Microsoft Defender SmartScreen. After switching to portal.vstbalance.com (which targets the same folder), the issue was resolved. How can we determine the specific actions that triggered the phishing label on Microsoft Edge? #phishing. #MicrosoftDefenderSmartScreen

Answer 1

The issue is resolved by the Microsoft support team. They don't respond about the issue.

Answer 2

You can refer to this doc to learn how Microsoft Defender SmartScreen determines whether a site is potentially malicious. In short:

• Analyzing visited webpages for indications of suspicious behavior.
• Checking the visited sites against a dynamic record of reported phishing sites.

If you need to report this site as safe, in the warning page, you should click More information --> Report that this site doesn’t contain phishing threats. This will take you to a feedback page where you can send feedback to the Microsoft Defender Team.
