SmartScreen reputation issue for EV Code Signed Windows application
Hello Microsoft Defender Threat Intelligence Team, We are the developer of a legitimate Windows desktop application called "ShangJing". Recently, our users reported that Microsoft Defender SmartScreen displays the following warning when downloading and launching our application: "Microsoft Defender SmartScreen can't verify this file is safe." The application is not malicious and has been digitally signed with a GlobalSign EV Code Signing Certificate. Application information: Product Name: ShangJing Publisher: Zhaoyi Information Technology (Shanghai) Co., Ltd. Certificate: GlobalSign EV Code Signing Certificate File: 尚镜_2.0.0_platinum_setup.exe Issue: Users receive SmartScreen reputation warning when downloading our application. We have already submitted the file through Microsoft Security Intelligence submission portal 7 days ago, but we have not received any update yet. Submission ID: 0c015296-b9cf-4130-9eaf-fc59cd145370 The file is distributed through our official website: https://www.changine.cn/downloads We would like to understand: 1. Is this caused by insufficient SmartScreen reputation for a newly released binary? 2. Is there any additional verification required from the software publisher side? 3. How can we ensure our legitimate application gains proper SmartScreen reputation? Our application is widely used for live streaming and camera-related workflows. It does not contain any malicious behavior. We would appreciate any guidance from the Microsoft team. Thank you.
Need information on generating sample events for Threat Intelligence" (both duplicate posts)
Two things are tripping this up, and they're common mix-ups: First — Attack Simulation Training doesn't generate Threat Intelligence events. If you used the built-in phishing simulator, its logs only show up under Email & collaboration → Attack simulation training → Simulations — they're intentionally excluded from real Threat Intelligence telemetry. That's likely why nothing's showing up even though you ran a campaign. Second — your EICAR test should actually work, but check the right place: not the generic Office 365 Management Activity API's AuditLogRecordType page in isolation — go specifically to the RecordType values used for Defender for Office 365 threat events: 28 = ThreatIntelligence (phishing/malware events) 41 = ThreatIntelligenceUrl (Safe Links time-of-click/block events) Plus ThreatIntelligenceAtpContent, ThreatFinder, MSTIC To reliably generate one: Confirm Purview audit logging is enabled for the tenant first — if it isn't, nothing downstream gets logged regardless of what you trigger. From an external mailbox, send a test user the EICAR string as a .txt attachment (exact 68-byte string, see Microsoft's anti-malware testing doc). Defender for Office 365 should detect and quarantine it. Verify it landed first in the portal UI: Email & collaboration → Explorer → Malware tab — if it's there, the underlying ThreatIntelligence record exists and the Management API call should return it (allow a short delay; these aren't instant). For the Safe Links side, send a known-safe-but-flagged test URL (Microsoft publishes test URLs for this) to trigger ThreatIntelligenceUrl. If it shows up in Explorer but still doesn't appear via the Management API, that's usually an API subscription/permission issue (you need an active subscription to the DLP.All or relevant Office 365 Management API content type, not just Graph permissions) — worth checking separately from the detection side.Can the Microsoft Defender portal show the server details as per security group?
Yes — this is exactly what Device Groups + RBAC are designed for in Microsoft Defender (assuming you're managing these servers through Defender for Endpoint, which is the typical path for cross-vendor server monitoring). The model: Device groups are the scoping unit (not Entra security groups directly) — create one per vendor/company (e.g., "Company A Servers", "Company B Servers"), using a matching rule (tag, OS, name pattern, etc.) to auto-assign devices. RBAC roles then get tied to an Entra security group and granted access to only specific device groups. So: Company A's people go in an Entra group → that group is assigned an MDE role scoped to "Company A Servers" only → they only ever see those devices, alerts, and incidents in the portal. You as admin keep your existing Global Admin/Security Admin role (or get added to both device groups' RBAC scope), so you retain visibility across both. Path: Settings → Endpoints → Permissions → Device groups to create the groups, then Permissions → Roles to create a role and tie it to your Entra security group with that device group as the scope. One thing to verify before committing to this design: this RBAC model affects what shows in alerts, incidents, advanced hunting (scoped automatically), and inventory — but make sure nobody from Company A/B also needs organization-wide Defender features like global threat analytics, since those aren't scopable the same way. If you're actually talking about servers monitored via Defender for Cloud (Azure subscription-based, not MDE-onboarded), the equivalent mechanism is Azure RBAC at the subscription/resource group level (assign Security Reader scoped to the RG containing Company A's VMs) — different mechanism, same outcome. Worth clarifying which portal/product this is so the right one gets recommended.
Microsoft Defender doesn't, Spy hunter shows a Hijacker
Spy Hunter indicates a "Elex Hijacker" and three other problems were as Defender and McAfee do not show any problem. Is Spy Hunter legitimate? I did have a Search engine redirect problem that has a name "ext.ladispatcher.com" and "search-load.com" while using Chrome browser with Chrome search engine. But no problem with Microsoft Edge and Bing. My monitor screen occasionally momentary collapses and reverts back to normal in a split second. Could there be a connection to malware.? Please let me know if i am posting on the wrong site.
Massive reduction in Threat Intelligence IP data since Monday 10th June
Hi, Anyone else see a massive reduction in Threat Intelligence IP data since Monday 10th June into Sentinel platforms? I operate two Sentinel environments and they both seen the same change. The screenshot below is the past 30 days. The past 48 hours still reports some IP information being sent but at a very reduced rate. What's changed with the feed?Need information on generating sample events for Threat Intelligence
Hi community, I am working on exploring MS Threat Intelligence and its features. But I am not able to generate sample data for this product, nor able to view the Threat Intelligence logs using Microsoft Management API following the schema - https://learn.microsoft.com/en-us/office/office-365-management-api/office-365-management-activity-api-schema#auditlogrecordtype I tried sending some mails from external email account to my organisation's test user containing EICAR files, and also tried with some safe but malicious test URLs. But still unable to get data inside Threat Intelligence. Can someone please help me here for generating events and viewing the content using Management APIs?

Hello, Microsoft Defender Vulnerability Management is recommending to update Python in my Azure VM Machines since version 3.9 has some critical vulnerabilities. We did the update to version 3.12 but only the Windows 2019 Datacenter machine is not appearing as Exposed Device anymore. The procedure to update Python in all machines was the same but the Windows 2016 Datacenter VM´s remains in the Exposed Device list. Because Python relies on Anaconda, it is not possible to remove the older version completely. The strange thing is why the same proceduro to update the software is seen as diferent by Microsoft Defender Vulnerability Management apparently. Any advice is highly appreciated. Thanks in advance Mirella
