Enrich an IOC (IP, domain, hash, URL) with threat intelligence. Use when you need to look up reputation and context for an indicator using GTI and SIEM. Returns threat intel findings, SIEM entity summary, and IOC match status.

Perform exhaustive analysis of a critical IOC. Use when an IOC needs Tier 2+ investigation beyond basic enrichment - includes GTI pivoting, deep SIEM searches, correlation with related entities, and threat attribution. For escalated IOCs requiring comprehensive investigation.
Complete Tier 1 triage workflow. Orchestrates the full alert triage process: check-duplicates, triage-alert, enrich-ioc for each entity, and either close (FP/BTP) or escalate (TP/Suspicious). Use for end-to-end alert processing.
Complete Tier 2 investigation workflow. Orchestrates deep investigation of escalated cases: deep-dive-ioc, correlate-ioc, specialized triage (malware/login), pivot-on-ioc, and generate comprehensive report. Use for escalated cases requiring thorough analysis.
Check for duplicate or similar cases. Use before deep analysis to avoid investigating the same incident twice. Takes a CASE_ID and returns list of similar cases.
Close a case or alert with proper reason and documentation. Use when triage determines an alert is FP/BTP or investigation is complete. Requires artifact ID, type, closure reason, and root cause.
Check for existing SIEM alerts and case management entries related to IOCs. Use to understand if an indicator has triggered previous alerts or is part of ongoing investigations. Takes IOC list and returns related alerts and cases.

Perform standardized enrichment for a single Indicator of Compromise (IOC) using Google Threat Intelligence (GTI) and Chronicle SIEM.
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"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:
Error Handling: If GTI fails (quota exceeded, IOC not found), note the limitation and proceed with SIEM enrichment.
secops-mcp.lookup_entity(entity_value=IOC_VALUE)
Store in SIEM_ENTITY_SUMMARY:
secops-mcp.get_ioc_matches()
Check if IOC_VALUE appears in results. Store Yes/No in SIEM_IOC_MATCH_STATUS.
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 |
