## Why falcon_add_ioc is rated Medium

This tool creates IOCs (Indicators of Compromise), which are new data artifacts added to a security system. This is a reversible write operation—IOCs can be updated or removed later. While it doesn't execute code or delete data, it does modify the state of the CrowdStrike system by adding security indicators.

From the tool's own definition: "Tool name 'falcon_add_ioc' and description 'Create one or multiple IOCs' indicate creation of Indicators of Compromise, which modifies data in a security system."

Risk signals: Adds indicators of compromise

## Use case

AI agents use falcon_add_ioc to create or update resources in CrowdStrike Falcon, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your CrowdStrike Falcon environment.
