Threat hunting is a powerful way for the SOC to reduce organizational risk, but it’s commonly portrayed and seen as a complex and mysterious art form for deep experts only, which can be counterproductive. Sophisticated cybercriminals burrow their way into network caverns, avoiding detection for weeks or even months, as they gather information and escalate privileges. If you wait until these advanced persistent threats (APT) become visible, it can be costly and time-consuming to address. In today’s cybersecurity landscape, SOC analysts need controls and integrated toolsets to search, filter, and pivot through their telemetry to derive relevant insights faster.
Taken into account, we are delighted to announce that we have introduced 80 new hunting queries that can empower your SOC analyst to reduce the gaps in your current detection coverage and ignite new hunting leads.
Hunting queries included:
The following queries are designed to help you find suspicious activity in your environment, and whilst many are likely to return legitimate activity as well as potentially malicious activity, they can be useful in guiding your hunting. If after running these queries you are confident with the results you could consider converting them to analytics or add hunting results to existing or new incidents.
The figure below illustrates the diversification and threat hunting coverage the new hunting queries provide across the MITRE ATT&CK framework matrix:
Feel free to expand the spoiler below to view the new list of out the box hunting queries and the MITRE ATT&CK tactics that are covered:Spoiler
How to access the new hunting queries:
All of the queries are available via the Hunting UI page. For this example, I will demonstrate how to filter the new Microsoft Teams hunting queries. To learn more, see article on the new Microsoft Teams data connector (Preview).
Navigate to the Azure Sentinel console, and select “Hunting” under the Threat Management area
Next, use the filter pills to filter the data source (TeamsData) for the hunting query. In this example, we are highlighting hunting queries that satisfy several use cases for Microsoft Teams:
