name: "Netskope IA - Geo Anomaly - Traffic to High-Risk Countries"
version: 1.0.0
kind: Scheduled
description: |
Detects web traffic routed to destination servers in high-risk countries. Identifies
users whose traffic terminates in sanctioned or known adversary-aligned nations,
which may indicate C2 communication, data exfiltration, or compromised infrastructure.
Uses the built-in NetskopeEvents_CL table from the Netskope Internet Access data connector.

This query is designed to detect and alert on web traffic from users that is being routed to servers located in high-risk countries. Here's a simple breakdown of what it does:
Purpose: The query identifies users whose internet traffic is going to countries considered high-risk, which could indicate potential security threats like command-and-control communication, data exfiltration, or compromised systems.
Data Source: It uses data from the NetskopeEvents_CL table, which is part of the Netskope Internet Access data connector.
High-Risk Countries: The query specifically looks for traffic going to countries such as Russia, China, North Korea, Iran, Syria, Cuba, Venezuela, and Belarus.
Conditions:
Output:
Alerting:
Severity and Techniques: The alert is marked with medium severity and is associated with MITRE ATT&CK techniques related to command and control and data exfiltration.
In summary, this query helps security teams monitor and respond to potentially suspicious web traffic to high-risk countries, providing insights into possible security incidents.
