Hello, we have some computers which we need to find out the specific registry value in order to be able to update their OS. The path: HKEY_LOCAL_MACHINE\software\policies\Microsoft\Windows\WindowsUpdate\AU The value (Dword): NoAutoUpdate I want to find out which computers that are onboarded to defender for endpoint has this registry set to "1"/On.

Join us on Thursday 28.7 for a webinar on Sentinel IT/OT Threat Monitoring with Defender for IoT solution. Learn how Defender for IoT's built-in integration with Sentinel helps bridge the gap between IT and OT security. Registration is now open , for July 28 There has been a long-standing split between ICS/SCADA (OT) and Corporate (IT) cybersecurity. This split was often driven by significant differences in technology/tooling. Microsoft Defender for IoT's integration with Microsoft Sentinel drives convergency by providing a single pane for coverage of both D4IOT (OT) and Microsoft Sentinel (IT) alerting. This solution includes Workbooks and Analytics rules providing a guide OT detection and Analysis.3.7KViews0likes8CommentsWhich schema belong to which service?
Hello there, So I'm pretty familiar with KQL and MDATPs default schemas found under Advanced Hunting. There are of course some more schemas/tables found under MTP compared to MDATP (https://security.microsoft.com/advanced-hunting Is there any general cheat-sheet on which schema originates from which service? For example if I would hunt under the "MiscEvents" schema, what do I need to do to add it? What I mean is, I would like to try this query: https://techcommunity.microsoft.com/t5/microsoft-defender-atp/hunting-for-reconnaissance-activities-using-ldap-search-filters/ba-p/824726 But I can't seem to find "MiscEvents" in either Log Analytics, Defender ATP or M365 Threat Protection. Do I miss something? Is Azure ATP needed for the "MiscEvents" table to be populated? Regards SimonSolved2.4KViews0likes2CommentsThreats > August 2019 RDP update advisory > Hunting Query

Microsoft Defender for IoT has released the November 2022 Threat Intelligence package. The package is available for download from the Microsoft Defender for IoT portal (click Updates, then Download file). Threat Intelligence updates reflect the combined impact of proprietary research and threat intelligence carried out by Microsoft security teams. Each package contains the latest CVEs (Common Vulnerabilities and Exposures), IOCs (Indicators of Compromise), and other indicators applicable to IoT/ICS/OT networks (published during the past month) researched and implemented by Microsoft Defender for IoT’s security research team, Section 52. November Updates With this release, Microsoft Defender for IoT has expanded vulnerability detection capabilities for known OT vulnerabilities across supervisory control and data acquisition (SCADA) devices issued since 2008 and included new detections for Text4Shell (CVE-2022-42889) and the recently released path traversal vulnerability in the implementation of the Totalflow TCP protocol in ABB (CVE-2022-0902). Detections for the Text4Shell vulnerability (CVE-2022-42889) in the “Apache Commons Text” Java library were added with this month’s threat intelligence update. This vulnerability allows an attacker to send malicious inputs that can execute arbitrary code, call a remote URL or send an unauthorized DNS request. Customers using Apache Commons Text versions between 1.5 and 1.9 are recommended to update to version 1.10. The November Threat Intelligence package contains high-severity CVEs, including CVE-2022-38465. An attacker exploiting this vulnerability in Siemens SIMATIC S7-1200 and S7-1500 CPU families could decrypt information such as passwords and gain full control of the programmable logic controller (PLC) allowing them to perform the following actions: Connect to the PLC Change the PLC’s configuration Upload ladder logic to the PLC Change PLC mode Attacks abusing this vulnerability will display normal behaviors and connections to devices, similar to authorized network and device administrators. Guidance Customers are recommended to update their systems with the latest TI package in order to detect potential exposure risks and vulnerabilities in their networks and on their devices. Threat Intelligence packages are updated every month with the most up-to-date security information available, ensuring that Microsoft Defender for IoT can identify malicious actors and behaviors on devices. Microsoft Defender for IoT researchers encourage you to review the implementation of devices and software included in the November Threat Intelligence package and to patch devices when relevant to reduce your attack surface. For customers affected by CVE-2022-38465, Microsoft strongly recommends following the mitigation guidelines published by Siemens. To download the firmware updates for S7-1200 directly, please click here, and for S7-1500, click here. Simatic S7-1200 models with firmware versions below v4.5 and S7-1500 models with firmware version below v2.9.2 need to be updated according to the mitigation guidelines. Microsoft Defender for IoT detects suspicious activity on devices by detecting unauthorized PLC activity and connections to unfamiliar and unauthorized IP addresses. Customers interested in identifying which devices may currently be vulnerable to exploitation by threat actors, should access their inventory in Microsoft Defender for IoT. The inventory contains the list of devices according to model and firmware version. For more information about these CVEs or your security posture, please contact us.

Microsoft Defender for IoT has released the July 2023 Threat Intelligence package. The package is available for download from the Microsoft Defender for IoT portal (click Updates, then Download file). Threat Intelligence updates reflect the combined impact of proprietary research and threat intelligence carried out by Microsoft security teams. Each package contains the latest CVEs (Common Vulnerabilities and Exposures), IOCs (Indicators of Compromise), and other indicators applicable to IoT/ICS/OT networks (published during the past month) researched and implemented by Microsoft Defender for IoT’s security research team, Section 52. The Threat Intelligence package for this month provides indicators to identify devices affected by the Rockwell Automation ControlLogix Firmware vulnerabilities CVE-2023-3595 and CVE-2023-3596, as well as detections designed to warn users of attempts to exploit these vulnerabilities. This package also includes indications for Honeywell Experion PKS, LX, and PlantCruise devices affected by the CVEs in ICSA-23-194-06 vulnerabilities (CVE-2023-23585, CVE-2023-25078, CVE-2023-2023-25948, CVE-2023-2023-26597, CVE-2023-24480, CVE-2023-25770, CVE-2023-25178, CVE-2023-22435, CVE-2023-2023-24474). Consequently, these devices may be vulnerable to remote code execution (RCE), denial of service (DoS), spoofing attacks, or they may even be disabled. Users must update their systems to the latest version to be safe from these vulnerabilities. Rockwell Automation and Honeywell have released patches to address these issues. It is recommended to install the patches as soon as possible. These CVEs can only be exploited by the attacker who has direct access to the systems that are affected. In order to mitigate the risks, we recommend the following measures: The affected devices should be updated with the latest firmware Keep a close eye on any unauthorized access attempts to the systems and minimize exposure and access to them. Ensure that network monitoring is monitoring systems with these devices to be able to detect and track any behavior deviations from baseline. Guidance Customers are recommended to update their systems with the latest TI package in order to detect potential exposure risks and vulnerabilities in their networks and on their devices. Threat Intelligence packages are updated every month with the most up-to-date security information available, ensuring that Microsoft Defender for IoT can identify malicious actors and behaviors on devices.
