How to remove SSL Certificate on CLI
How can an SSL certificate get removed on the backend through the CLI? When I delete the cert in the GUI, it doesn't seem to actually get removed from the backend. The cert doesn't show in the GUI, but the cert is still recognized in the browser so it appears apache is still seeing it serving it up. There's a cert folder at: /var/cyberx/keys/certificates There's a properties folder at: /var/cyberx/properties Do I just remove the folder and restart apache? Are there any .properties files that need modified?Solved1KViews0likes1CommentIs Raspberry PI Bullseye also supported by Defender for IoT agent installation?
Hello, As Azure IoT Edge is https://azure.microsoft.com/en-us/updates/azure-iot-edge-supports-debian-bullseye-arm32v7/ on a Raspberry PI, I was hoping to install the Defender for IoT agent on this device. But when I follow the Debian installation steps, I get an exception: sudo apt-get install defender-iot-micro-agent Reading package lists... Done Building dependency tree... Done Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: defender-iot-micro-agent : Depends: libcurl3 but it is not installable E: Unable to correct problems, you have held broken packages. Unfortunately, I'm not able to install libcurl3: sudo apt install libcurl3 Reading package lists... Done Building dependency tree... Done Reading state information... Done Package libcurl3 is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source However the following packages replace it: libcurl4 E: Package 'libcurl3' has no installation candidate Because libcurl3 is mandatory instead of optional, I'm not able to let the installer ignore it. Is there some solution? Thanks, SanderSolved4.8KViews0likes4CommentsDefender for Endpoint - macOS scan takes 1 second
Hello, We use Defender for Endpoint on macOS deployed by Mosyle MDM. However, we noticed when user run quick or full scan that action takes 1 second and that is it - 0 files scanned. This used to work before; I happen to have a screenshot: Now, if I run scan from command line, again the same: We use config profiles from here: https://github.com/microsoft/mdatp-xplat/tree/master/macos/mobileconfig/profiles mdatp health output: Did anyone have this issue?

Hello, I’m running into a recurring issue on Windows Server 2019 Datacenter VMs running in Azure where MsMpEng.exe (Antimalware Service Executable) consistently spikes CPU usage every day. Here’s what I’ve observed so far: Microsoft Defender pulls threat intelligence from the cloud continuously in real-time, in addition to multiple scheduled updates per day. Despite this continuous checking, I’ve noticed a consistent CPU spike only between 4:40 PM and 4:55 PM daily. During this time, Defender consumes 100% CPU. I’ve checked Task Scheduler and Defender scan settings — there are no scans or tasks scheduled during this period. Limiting CPU usage using Set-MpPreference -ScanAvgCPULoadFactor 30 has had no effect on these background maintenance routines. Automatic provisioning via Defender for Cloud is enabled on these Azure VMs, so the MDE agent installs and updates automatically. Logs from Microsoft-Windows-Windows Defender/Operational during the high CPU window: 10/2/2025 4:41:57 PM 2010 Microsoft Defender Antivirus used cloud protection to get additional security intelligence... 10/2/2025 4:41:57 PM 2010 Microsoft Defender Antivirus used cloud protection to get additional security intelligence... 10/2/2025 4:49:41 PM 1150 Endpoint Protection client is up and running in a healthy state... These logs confirm that Defender’s cloud intelligence updates and endpoint checks run exactly during the CPU spike window. Even though Defender continuously checks for cloud protection updates throughout the day, the CPU spike occurs only during this particular window. The pattern is consistent across multiple Azure VMs, suggesting this is part of Defender’s automated behavior. Questions for the community: Is this behavior expected for Azure VMs, or could it indicate a bug in Defender on Windows Server 2019? Is there a supported way to throttle, defer, or better manage CPU usage during these maintenance and cloud intelligence routines? Are there recommended best practices for always-on production environments in Azure to avoid performance degradation caused by Defender? Any guidance or advice would be really appreciated.

When you create a Microsoft Defender Antivirus policy for Linux in the Endpoint Security Policies blade of the Defender admin center, there are two settings in the Antivirus Engine section that have "(deprecated)" after them: "Enable real-time protection (deprecated)" and "Enable passive mode (deprecated)": What exactly does "deprecated" mean in this context? I can't imagine that the features themselves are deprecated; are we supposed to be configuring them elsewhere?Solved198Views0likes2CommentsGet-MpPerformanceReport empty processpath

Dear Community We use PRGT, which monitors various things for our customers. One of our customers uses Microsoft Defender, which issued an alert for “SmokeLoader.” After some research, we found that this is caused by two of our scripts, which establish a connection to our servers and query various things. This raised the question of how we can best whitelist this, since the detection comes from “WinRM” and not directly from the script itself. However, the script itself establishes a connection to the servers and requests some information. Are there any sensible measures that can be taken here, because only whitelisting the script (folder or hash) makes limited sense here, since the detection in this case was for the WinRM process. So the behavior analysis would kick in again. Thank you for your time! Best regards, SleeperHeadSolved112Views0likes1CommentWhen is a device considered deleted or inactive in the DeviceInfo table?
Hi, I’m trying to better understand how device lifecycle is handled within Microsoft Defender for Endpoint, specifically in the context of Advanced Hunting via the DeviceInfo table. When can we consider a device as deleted or removed from the DeviceInfo table? How long do offboarded or inactive devices remain in the DeviceInfo table before they are automatically purged? Are there specific values (e.g., onboardingStatus, lastSeen, isActive, etc.) or time-based thresholds that should be used to determine if a device is no longer active? Any guidance or documentation references would be greatly appreciated!Solved147Views0likes1CommentHow to Automatically Export Microsoft Defender Security Recommendations with Historical Tracking
Hi everyone, I'm currently using Microsoft Defender for Endpoint, and I'm looking for a way to automate the export of security recommendations. Right now, the only available option is to manually export these recommendations as a CSV using the "Export" button in the portal. However, I’d like to: Automatically pull these recommendations regularly Store them in an Azure SQL database/Azure Storage Use Power BI to create dashboards and track trends over time (since Defender does not provide historical views) Is there a way to fetch this data programmatically? My Goal: Automatically query this API daily (via Azure Function or Azure Automation or any other way) Store each day's results in an Azure SQL table/Storage account with timestamps Build Power BI reports for: Most frequent vulnerabilities Exposure trends over time Recommendation coverage and progressSolved257Views0likes2CommentsASR rule blocking execution of OneDriveSetup.exe
A member of our Service Desk team was working with a user to troubleshoot an issue with the OneDrive sync client on their Windows workstation. As part of their troubleshooting, they uninstalled the client with the intent to re-install it, but when they attempted to run OneDriveSetup.exe, they received an error. It turned out that execution was being blocked by the "Block use of copied or impersonated system tools" Attack Surface Reduction rule. I was able to work around the issue by creating an exception in our Attack Surface Reduction Rules policy, but this situation consumed most of my morning and seriously impacted the productivity of one of our users, so I would like to ensure that it does not happen again. Should I report this as a false positive (per https://learn.microsoft.com/en-us/defender-endpoint/troubleshoot-asr#report-a-false-positive-or-false-negative ), or is this policy somehow working as designed? If it is the latter, what is the correct approach for reinstalling the OneDrive sync client on a machine with this ASR rule applied to it?Solved428Views0likes2Comments- 255Views0likes6Comments
Indicators added for URL with setting 'Audit'. But where can I review those?
Was asked to put a few domains on a watchlist to see how often they're actually requested from endpoints in our organization. Went to Defender, Settings, Endpoints, Indicators, and added the domains there with the action set to 'audit'. I figured I should be able to review something in the Audit logs of Defender itself, but all I see there are the actions I did when adding the URLs to the indicator list. Anyone have any idea where I can review the usage of those websites I've set to audit, so we can determine if it's feasable to shut them down or not?Solved116Views0likes2CommentsCan I use Microsoft Defender for Endpoint for CIS benchmark assessment
