KQL Search

This query is designed to identify and summarize network events related to potentially malicious domains, specifically focusing on piracy-related indicators of compromise (IOCs). Here's a simple breakdown:

1. Data Import: It starts by importing a list of piracy-related indicators from an external CSV file hosted on GitHub. This file contains a column named IndicatorValue, which presumably lists domain names associated with piracy activities.

2. Domain Extraction: The query extracts these domain names into a list called DomainList.

3. Event Filtering: It then searches through DeviceNetworkEvents to find any network events that have occurred in the last 90 days (TimeGenerated > ago(90d)) where the RemoteUrl (the domain accessed) matches any domain in the DomainList.

4. VirusTotal Link Creation: For each matching event, it creates a link to the VirusTotal website for further investigation of the domain. This is done by appending the domain name to a base VirusTotal URL.

5. Summarization: Finally, it summarizes the results by counting the number of events for each domain and provides a link to VirusTotal for each domain.

In essence, this query helps identify and quantify network activity related to known piracy domains, providing a quick way to assess potential threats and investigate them further using VirusTotal.
