[arielsgv]

Microsoft has released the April 2021 Threat Intelligence update package. The package is available for download from the Azure 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. 

The package includes the latest CVEs (Common Vulnerabilities and Exposures) and IOCs (Indicators of Compromise) applicable for IoT/ICS/OT networks (published during the month of March).

CVEs provide a reference method for publicly known information security vulnerabilities and exposures, and are available for reference on the MITRE site, in the National Vulnurability Database site (NVD) as well as IoT/OT specific ICS-CERT.

In addition to the updated IOC artifacts in the package for the month of March, there are also detection rules for Solorigate associated malware (GoldMax, GoldFinder, and Sibot), follow this link to read more.
