Hi We are using the mto portal to hunt across multiple tenants. My team get the "loading completed with errors" message and the prompt for "MFA Login Required". When they select this the window to authenticate opens and then closes instantly. When selecting the tenant name they can authenticate in a new tab directly to Defender in this tenant without any issue (but this does not carry over to the MTO portal). The old behaviour was that they selected "MFA Login Required" and they could authenticate to the tenants they needed to at that time. Is this happening to anyone else? Does anyone have any tips for managing multiple Defender instances using MTO? Thanks73Views0likes2CommentsMSSP Multi-Tenant Handling with Lighthouse and Defender XDR
Hello, As far as I know an MSSP providers, leverages Azure Lighthouse to call and access multiple customer workspaces, which allows to manage analytics across tenants. My questions are: In the case of moving to Defender XDR, how would this be possible in a multi-tenant MSSP scenario? Even with Lighthouse, how does Defender XDR avoid merging incidents/alerts across different customers when the same entities are involved? How does Defender XDR differentiate identical IOCs (same IP, hash, etc.) that appear in multiple customers? Can MSSPs customize correlation logic to prevent false cross-tenant merges? Content Ownership & Sharing Most MSSPs do not want to share their proprietary content (custom rules, detections, playbooks, analytics, etc.) with customers. How is Defender XDR approaching this requirement to ensure MSSPs can operate without exposing their intellectual property? Example: Customer Test 1 has a port scan incident from IP 10.10.10.10. Customer Test 2 also has a port scan incident from the same IP 10.10.10.10. In Sentinel today, these would remain separate. But in Defender XDR, would these two alerts risk being merged into a single incident because the same entity is detected across tenants? Thanks in advance for any clarification.221Views0likes2CommentsDefender is missing logs for files copied to USB device on Mac devices
Hello, I am currently facing an issue with Defender not logging files copied to USBs. Using the KQL below, I can only see .exe files copied, but nothing when it comes to .pdf, .docx. .zip and other standard file extensions. Has someone come across this issue before? Any help is greatly appreciated let UsbDriveMount = DeviceEvents | where ActionType=="UsbDriveMounted" | extend ParsedFields=parse_json(AdditionalFields) | project DeviceId, DeviceName, DriveLetter=ParsedFields.DriveLetter, MountTime=TimeGenerated, ProductName=ParsedFields.ProductName,SerialNumber=ParsedFields.SerialNumber,Manufacturer=ParsedFields.Manufacturer | order by DeviceId asc, MountTime desc; let FileCreation = DeviceFileEvents | where InitiatingProcessAccountName != "system" | where ActionType == "FileCreated" | where FolderPath !startswith "C:\\" | where FolderPath !startswith "\\" | project ReportId,DeviceId,InitiatingProcessAccountDomain, InitiatingProcessAccountName,InitiatingProcessAccountUpn, FileName, FolderPath, SHA256, TimeGenerated, SensitivityLabel, IsAzureInfoProtectionApplied | order by DeviceId asc, TimeGenerated desc; FileCreation | lookup kind=inner (UsbDriveMount) on DeviceId | where FolderPath startswith DriveLetter | where TimeGenerated >= MountTime | partition hint.strategy=native by ReportId ( top 1 by MountTime ) | order by DeviceId asc, TimeGenerated desc | extend HostName = iff(DeviceName has '.', substring(DeviceName, 0, indexof(DeviceName, '.')), DeviceName) | extend DnsDomain = iff(DeviceName has '.', substring(DeviceName, indexof(DeviceName, '.') + 1), "") | extend FileHashAlgorithm = 'SHA256'Solved69Views0likes2CommentsHow to use KQL to associate alerts with incidents?
There is no method I'm aware of to use KQL to query from an alertID to an incident or vice versa. Please provide kql examples for querying between XDR incidents and alerts. These queries should be independent of the SecurityIncident table which is only available when Sentinel is connected to XDR. Thank you.156Views0likes1CommentMS Defender Azure Arc Logic App
What is the best procedure for configuring a Logic App for Microsoft Defender in an Azure Arc environment? We had a very unexpected experience during onboarding—after configuring the Logic App, we missed setting a cap, and within a week, it consumed over $18K USD. I believe there must be a way to fine-tune the configuration to optimize costs. From my perspective, no organization would adopt an environment with such high costs for Microsoft Defender Plan 2 without better cost control measures in place. Could you suggest best practices or optimizations to prevent such excessive consumption?127Views0likes1CommentWeird 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?132Views0likes2CommentsData at rest Europe
Why in the world would MDE and XDR default ro Europe when our entire cloud services host oir of eastus? Data at rest shows Europe instead of eastus which is oue default tenant. Also the fact that XDR setup failed to ask set region is biggest bug in this stack along with MDE. what would have caused these two to get setup in europe and is thia configurable somewhere defender portal or other portal? I have read all the docs with only option would be to redo the entire setup. If we decided to start from beginning who holds the key to set desired region for all these modules? Is this EA, Tenant Admin, Microsoft Support? also streaming logs inter continental from Europe to log analytics in eastus, whats the cost ingestion? I show several pricing model but with my use case i need ti know dollar amount per gig for both. Not happy how illusive defender operates if not careful during initial setup from admin perspective or it could have been microsoft that managed to click through without looking159Views0likes5CommentsDefender 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.

We have a requirement to implement LDAPS auth for an appliance against AD DCs in a legacy environment. The DCs are running Defender for Identity. While testing, using LDAP, I can trace login events in the IdentityLoginEvents table, however when switching to LDAPS, I can't see any related events logged here. Interactive logins using LDAPS are working successfully, as expected, and appear in the Windows event log as EventID:4776 on the DC (but don't appear in the defender portal). It was then that I discovered that this expected behaviour according to the list of supported logon types listed here. https://learn.microsoft.com/en-us/defender-xdr/advanced-hunting-identitylogonevents-table I'm puzzled that XDR would support a cleartext legacy authentication method like LDAP, but would not support the more secure LDAPS protocol. Is there any rationale for this, or intention to introduce support ?125Views1like0Comments
