I became aware about the topic by this user comment of  German blog reader Hans Thölen. He wrote:

The link More informations in Windows Update dialog box opens the site Security intelligence updates for Windows Defender Antivirus and other Microsoft antimalware in Internet Explorer. There you will learn that Microsoft continuously updates the security information in anti-malware products. The goal is to cover the latest threats and constantly optimize the detection logic. The goal is to improve the ability of Windows Defender Antivirus and other Microsoft antimalware solutions to accurately identify threats.

This security intelligence works directly with cloud-based protection to deliver fast and powerful next-generation AI-based protection. Microsoft Security Intelligence updates include software that includes third-party material. Information can be found under Notices and Third Party Information.

The Update from Juli 31, 2019

The website contains the information that a Security Intelligence Update version 1.299.891.0 was released on 31.7.2019. The update is to be installed automatically and can be downloaded there for the various platforms, from Microsoft Security Essentials (Windows 7) to Windows Defender (Windows 8.1, Windows 10) to System Center 2012 Configuration Manager and Microsoft Forefront Protection & Co. The website also tells you how to trigger updates manually using commands from the command prompt.

Updates des Network Inspection System (NIS)

On the website you can find out that the following products use updates of the Network Inspection System (NIS): 

  • Microsoft Security Essentials
  • Forefront Endpoint Protection
  • System Center 2012 Endpoint Protection

These updates are designed to protect systems from network threats. This also applies to exploits that are supposed to take effect on the network during transmission. Microsoft recommends that you check the version of the Antimalware Client component on your security software and download the correct version of the NIS updates for the platform you are using.

What changes with Update Version 1.299.891.0?

Microsoft now maintains the Change logs for security intelligence update page, which currently refers to the changes in Version 1.299.891.0.

On the page you can select the update version via the list box and see what new malware attacks are detected. Two Trojans have been included in the detection. In the ‘Severity’ column, the severity of the threat is listed. In the last update, no Thread Detections were added.

However, if you select older updates, you will find entries to detect potentially unwanted applications/software (PUA) or Trojans. The Trojans Winnti, the Ransomware Ryuk or the Exploit Exploit:O97M/CVE-2017-11882 for exploiting the vulnerability CVE-2017-11882 in the old Office Formula Editor (see Hacker are misusing CVE-2017-11882 in Office EQNEDT32.EXE) are detected by the update version 1.299.843.0 of July 30, 2019.

Meanwhile, Microsoft also maintains the blog on Microsoft security intelligence, where you can always find the latest articles on security issues. On 29 July 2019, for example, there was this article which deals with the further development of the functions of Microsoft Thread Protection

In addition, there is the Microsoft Security Scanner on this page, a scan tool that was developed to detect and remove malware from Windows computers. The tool can be downloaded and run. Then it is scanned to find malware, so that if it hits you can try to eliminate the infection or reinstall the system to eliminate it. On this page you will find hints on how to use the tool.
