Observed Automation Discrepancies
Hi Team ... I want to know the logic behind the Defender XDR Automation Engine . How it works ? I have observed Defender XDR Automation Engine Behavior contrary to expectations of identical incident and automation handling in both environments, discrepancies were observed. Specifically, incidents with high-severity alerts were automatically closed by Defender XDR's automation engine before reaching their SOC for review, raising concerns among clients and colleagues. Automation rules are clearly logged in the activity log, whereas actions performed by Microsoft Defender XDR are less transparent . A high-severity alert related to a phishing incident was closed by Defender XDR's automation, resulting in the associated incident being closed and removed from SOC review. Wherein the automation was not triggered by our own rules, but by Microsoft's Defender XDR, and sought clarification on the underlying logic.
KQL script report last reboot/reset endpoint devices (Workstations/Laptops)
Hello everyone, I'm reaching out for assistance with a challenge I'm facing in Microsoft Defender. In my organization, we have numerous endpoint devices with vulnerabilities, and I suspect that the issues may stem from either inadequate patching or misconfigured Group Policy Object (GPO) settings preventing updates or reboots. To investigate further, I need a KQL script that can generate a report showing when each endpoint device was last rebooted or reset, along with the computer name and the last user who logged in to that device. I've attempted to use the following KQL script in different ways without success: DeviceEvents | where ActionType == "Restarted" or ActionType == "Shutdown" | summarize LastReboot = max(EventTime) by DeviceName Despite trying various approaches and searching through online forums, I haven't been able to obtain the desired results. I'm unsure if this information can be retrieved through Defender or if there's an alternative method I should explore. Any guidance or suggestions would be greatly appreciated as I work to identify and resolve these issues. Thank you for your assistance! Best regards, Sergio
Full Automation Capabilities in Linux OS
Hello eveyone, We have configured Defender to detect viruses, and our goal is that if one of our assets downloads or encounters a virus, it is automatically hidden or removed. Based on the documentation regarding the automation levels in Automated Investigation and Remediation capabilities, we have set it to "Full - remediate threats automatically." While this works correctly on Windows devices, we have noticed that on Linux devices, the defender still detect the virus but it was not prevented. I was wondering if anyone has encountered this issue and, if so, how it was resolved? Additionally, as I am new to the Defender platform, I wanted to ask if could this issue potentially be resolved through specific Linux policies or functionalities? Best regards Mathiew
Pending actions notification via KQL / Graph API
Hello, I'm looking for a way to get notifications when an investigation is in Pending Approval state. I have tried searching the logs in Defender and Sentinel and have tried finding a graph request that could get this information, but no luck. Is this something that exists? Thank you for any help regarding this topic. Kristof
