Scan extracted IoCs against VirusTotal threat intelligence database
AI agents call scan_with_virustotal to retrieve information from HeaderHawk without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads threat intelligence data from VirusTotal's database to classify indicators of compromise. It has no capability to modify data, execute code, delete records, or move money. The blast radius of misuse is minimal: an agent could generate false positives or waste API quota, but cannot harm systems or data. This is a straightforward read/query operation.
From the tool's definition The tool description states it 'scan[s] extracted IoCs against VirusTotal threat intelligence database' — a query operation that retrieves threat intelligence data without modifying, executing, or deleting anything.
