Weird updates "Security Threat Intelligence" on desktop
Hi guys, my name is Mo and I am new to the XRD community 🥰 I m observing anomalous device behavior. Upon login or wake-up, multiple virtual machines are active, some exhibiting headless screen reader functionality. This issue emerged following the installation of Microsoft security threat intelligence updates. Considering Windows Defender's machine learning and predictive maintenance capabilities, I question the deployment of these updates to my system. Is this update a standard Windows component? The associated URL is currently inaccessible. I acknowledge the potential of XR, CDN, and Hologres technologies (and other Azure/cloud-enabled features) to alter user experience. Could someone provide clarification regarding these iterative security updates? My usage is limited to cloud platforms and reputable open-source software; I do not utilize malicious websites. Thank you. #misclassification?
Custom critical filter for EDR/XDR
Hello everyone, i would like to ask if somebody is trying to make a unique "critical" filter for alerts/incidents that need to be done as fast as possible? We have many high alerts and we are trying to figure one to have prio list with important notifications. Have you any ideas? Thank you.Defender MDO permissions broken (again)
Defender wasn't letting me approve pending AIR remediation options, something I do every day, with my usual custom RBAC role checked out. Nor could I move or delete emails. I also had Security Operator checked out. I checked out Security Admin and tried again, no dice. It wasn't until I checked out Global Admin until I got the permissions I needed.

Administrative activity from a non-corporate IP address
Hi, Defender XDR raises incidents almost every day regarding OneDrive for Business sharing policies. Event description is: Change sharing policy: OneDrive Site Collection <b>https://xxxx-my.sharepoint.com/personal/user_domain_fi</b>; Parameters: property <b>Share Using Anonymous Links</b> <b>True</b>, property <b>Share With Guests</b>, property <b>ShareUsingAnonymousLinks</b> <b>From False To True</b>, property <b>ShareUsingAnonymousLinks - New Value</b> <b>True</b> Anonymous links are not allowed and when checking users onedrive site collection settings after alert it is still not allowed. Are these only false positives? Matched policy is Administrative activity from a non-corporate IP address and Alert Product is Microsoft Defender for Cloud Apps ~ Jukka ~Defender XDR - how to grant "undo action" Permissions on File Quarantine?
Dear Defender XDR Community I have a question regarding the permissions to "undo action" on a file quarantine action in the action center. We have six locations, each location manages their own devices. We have created six device groups so that Accounts from Location 1 can only manage/see devices from Location 1 as well. Then we created a custom "Microsoft Defender XDR" Role with the following permissions. This way the admins from location 1 can manage all Defender for Endpoint Devices / incidents / recommendations etc. without touching devices they aren't managing.. very cool actually! BUT - if a file gets quarantined, it might want to be released again because of false positive etc. I can do that as a global admin, but not as an admin with granularly assigned rights - the option just isnt there.. I don't want to give them admins a more privileged role because of - you know - least privileges. but i don't have the option to allow "undo action" on file quarantine events, besides that being a critical feature for them to manage their own devices and not me having to de-quarantine files i dont care about.. Any thoughts on how to give users this permission?
Defender console - Disabled Connected to a custom indicator & Connected to a unsanctionned
Updated - November 2024 I have found a way to disabling these annoying alerts. Look for the solution above. Issue: I want to know how I can disable these two following alerts : Disabled Connected to a custom indicator Connected to an unsanctioned blocked app Those alerts type needs to be enabled or disabled on demand, like the other alerts types. Why's that : Description of the workload : When we block(Unsanctioned) an application through Defender for Cloud apps. It creates automatically the indicators to Defender XDR. When someone for example click or go the URL related to the application, the following alerts will be triggered. When an indicator is automatically created through that, it checks the box to generate alert when the indicator is triggered. We would like to automatically uncheck the box or disable to alerts describing. Possible to disable the custom alert in setting ? No. Why ? Explanation : You cannot suppress "custom detection". But, they are categorized as "Informational" and you can suppress severity alert type. Solutions : IMPORTANT: Make sure to create a transform rule to not ingest this alerts in Sentinel. That could increased the Resolved incident ingestion and false your SOC optimization reports. The rule is automatically close only the “Informational” alerts with the specified titles. Other Informational alerts with different titles will not be affected. In the Defender XDR setting->Alert tuning->Create this rule: Here's an example: Rule Analysis From the updated rule configuration screenshot, it appears that you’ve set up a filter in the AND condition to only automatically close Informational alerts that do not match specific alert titles (e.g., “Malware was detected in an email message,” “unwanted software,” “malware,” “trojan”). This approach should ensure that the rule closes all Informational alerts except those that contain these specified titles. Here’s a breakdown of how it’s working: 1. Severity Filtering: By setting Alert severity to Informational, only Informational alerts are considered. 2. Title Exclusion: Adding Not equals conditions for each title you want to exclude prevents this rule from affecting those specific alerts. So, any Informational alert with a title that does not match the specified exclusions will be automatically closed. This setup should effectively allow you to close all unwanted Informational alerts while retaining visibility on any malware or security-related Informational alerts that require further review.
