Microsoft Defender Blocking an iframe in Dynatrace

[rgarzon1]

Hello everyone, I am facing an issue with Dynatrace in the many environments (i just tested at least 10 of my enviroments) and Microsoft Defender is blocking an iframe with the source https://{environmentid}.apps.dynatrace.com/ui/apps/dynatrace.classic.hosts, flagging it as malware.

Error Message from DevTools Console: "An iframe on this page was blocked by Microsoft Defender (Malware)."

Browser:  Edge - Versión 136.0.3240.92 (Compilación oficial) (64 bits)

this is no happening in Chrome, Brave, Firefox. just in Edge i just validate with some friends and its happening only in edge. 

i will notify this as secure but still its a little bit strange

Hello @rgarzon1,

We've tried to reproduce the behavior with the dynatrace.classic.hosts app using Edge as a browser, but we can't replicate the issue that you've described. 

Could you check back with the IT department / MS Defender admins at your organization, why Defender itself identifies the resource as potentially malicious?

Hi @MaciejNeumann 

This is not happening in all tenants, i have like 30 distinct tenants and have this behaviour in 2 of them. you can check this ticket 486876 for info related to this. but its not in all tenants, i just posted here trying to find more answers 😅
