Enrich IOC Skill

Perform standardized enrichment for a single Indicator of Compromise (IOC) using Google Threat Intelligence (GTI) and Chronicle SIEM.

Inputs

IOC_VALUE - The indicator value (e.g., "198.51.100.10", "evil-domain.com", "abcdef123456...", "http://bad.url/path")
IOC_TYPE - The type: "IP Address", "Domain", "File Hash", or "URL"

Workflow

Step 1: GTI Enrichment

Based on IOC_TYPE, call the appropriate GTI tool:

IOC Type	Tool	Example
IP Address	`gti-mcp.get_ip_address_report`	`get_ip_address_report(ip_address="198.51.100.10")`
Domain	`gti-mcp.get_domain_report`	`get_domain_report(domain="evil-domain.com")`
File Hash	`gti-mcp.get_file_report`	`get_file_report(hash="abcdef123...")`
URL	`gti-mcp.get_url_report`	`get_url_report(url="http://bad.url/path")`

Store key findings in GTI_FINDINGS:

Reputation score
Classification (malicious, suspicious, clean)
Key relationships (contacted domains, IPs, etc.)
Associated malware families or campaigns

Error Handling: If GTI fails (quota exceeded, IOC not found), note the limitation and proceed with SIEM enrichment.

Step 2: SIEM Entity Lookup

secops-mcp.lookup_entity(entity_value=IOC_VALUE)

Store in SIEM_ENTITY_SUMMARY:

First/last seen timestamps
Related alerts
Associated assets/users

Step 3: SIEM IOC Match Check

secops-mcp.get_ioc_matches()

Check if IOC_VALUE appears in results. Store Yes/No in SIEM_IOC_MATCH_STATUS.

Required Outputs

After completing this skill, you MUST report these outputs:

Output	Description
`GTI_FINDINGS`	Summary of GTI report (reputation, classification, relationships)
`SIEM_SUMMARY`	SIEM entity context (first/last seen, related alerts)
`IOC_MATCH_STATUS`	Yes/No - whether IOC appears in recent threat feed matches
`THREAT_SCORE`	Numerical threat score (0-100) based on GTI reputation
`MALICIOUS_CONFIDENCE`	Confidence level: `high`, `medium`, `low`, or `none`

Quick Reference

GTI Tools:

get_ip_address_report(ip_address)
get_domain_report(domain)
get_file_report(hash)
get_url_report(url)

SIEM Tools:

lookup_entity(entity_value)
get_ioc_matches()
