Very High Increase in CPU activity after Update Microsoft Defender for Identity sensor
All our servers that are running this sensor (DCs, Certificate servers, AD Connect servers) showed a massive increase in average CPU utilization from virtually straight after the sensor was automatically updated to version 2.254.19112.470 (late night UK time). Two of our DCs are sitting on 100% CPU today and we can't find anything to resolve it. Has anyone else seen this since running this version and if so what actions did you take ? How would we go back to rolling back to the previous version when it appears it will just be automatically updated soon after ? This is our monitoring of CPU utilization from one of the majorly affected DCs but every server with the sensor had the exact same graph showing a major increase in CPU at the same date and time i.e. just after the sensor was updated.
Easiest way to view remediated risk detections?
I'm looking in Lighthouse at a series of risky logins that are remediated. The thing is, this tenant previously experienced a breach that got remediated, so I'm trying to be extra cautious. When I click "View in Entra", it brings up no risk detections. If I navigate to Protection > Risky Activities > Risky Sign-Ins I get nothing. Switching to all statuses, I still get nothing. Same thing happens if I got to Risk Detections, nothing. Short of bringing up each user, and checking every single login to try to find what was risky, is there a way I can see these once the statuses are remediated? It seems like I SHOULD able to... But here are the different ways I've tried filtering Risk detections: Risky Sign-Ins Trying to understand the users popping in Lighthouse, but they don't appear with any of these filters (or the defaults).... Anyone able to advise? THanksUnable to access Update 3 for Microsoft Advanced Threat Analytics 1.9
Hi, Microsoft Tech Community and Ricky Simpson from Microsoft, I cannot download Update 3 for Microsoft Advanced Threat Analytics 1.9. Whenever I tried to access the download update from this https://support.microsoft.com/en-us/topic/description-of-update-3-for-microsoft-advanced-threat-analytics-1-9-954cb9b7-9646-78ce-2000-2a257b64df7c, it seemed the ID number 56725 was missing, and an error code of 404 was returned. Tried URL: https://www.microsoft.com/download/details.aspx?id=56725 Hope you can fix this problem as soon as possible, because Microsoft ATA still plays an important role in most of the enterprise network, including my company's network. Best regards for all people in the community
Missing remediation actions
Hi everyone, Remediation actions such as Disable/Enable user in AD, Force password reset are currently not available through the Defender portal (user page, advanced hunting). Anyone aware of this change? https://learn.microsoft.com/en-us/defender-for-identity/remediation-actions#supported-actions
MDI & gMSA config
Hi, We have followed the MDI Deployment guide from Microsoft: https://learn.microsoft.com/en-us/defender-for-identity/deploy/deploy-defender-identity We have also cross referenced this guide: https://jeffreyappel.nl/how-to-implement-defender-for-identity-and-configure-all-prerequisites/ The MDI Portal shows the gMSA account. The MDI agents are running fine and reporting to the MDI Portal. However, when we look at Services.msc on the Domain Controllers, the MDI agent runs under the security context of "Local Service" and not the gMSA account. Can anyone advise us on whether this is correct? or should we see the gMSA account in Service.msc console? And what other config may be required to make it run under the gMSA account? Thank you SK (screenshot below)
