Atomic Runbook: Get File Hash Threat Intel via SecOps MCP

ID: RB-ATOM-HASH-002 Version: 1.0 Last_Updated: 2025-05-30 Purpose: To retrieve general threat intelligence about a file hash using the Chronicle secops-mcp get_threat_intel tool. This serves as a supplementary check for narrative context or an alternative if specialized tools yield no results. Parent_Runbook(s)/Protocol(s): rules-bank/indicator_handling_protocols.md#3-atomic-indicator-file-hash, rb_hash_get_gti_report.md (as potential next step) Trigger: When a file hash requires external threat intelligence, possibly after a GTI check, or if broader textual context is needed.

---

Inputs Required

• file_hash: string - The file hash (MD5, SHA1, or SHA256) to query.
  • Source Example: Alert data, output from other tools.
• gti_confidence (optional): string - Confidence from a preceding GTI check (e.g., "Unknown_Reputation_GTI").

---

Execution Steps

1. Tool Selection:
   • Primary_Tool_MCP_Server: secops-mcp
   • Primary_Tool_Name: get_threat_intel
2. Parameter Mapping:
   • Construct query: query: "Provide threat intelligence summary for file hash {file_hash}"
3. Execute Tool: Call get_threat_intel with the query.
   • AI Agent Note: Refer to rules-bank/mcp_tool_best_practices.md.
4. Data Transformation/Extraction:
   • Output is textual. AI may parse for keywords.

---

Outputs Expected

• secops_ti_summary: string - Textual threat intelligence summary.
• identified_keywords: list (optional) - Keywords extracted by AI (e.g., "malware", "dropper", "benign utility").
• output_status: string - ["Success", "Failure"]
• output_message: string (if Failure).

---

Decision Logic / Next Steps (If Applicable)

• IF output_status is "Success":
  • IF secops_ti_summary contains "known malicious", "malware family", "trojan" THEN
    • Flag Hash as "High_Risk_SecOpsTI".
    • Proceed to rb_hash_lookup_entity_chronicle.md.
  • ELSE IF secops_ti_summary contains "suspicious", "hacktool", "PUA" OR (gti_confidence was "Unknown_Reputation_GTI" AND summary is not explicitly benign) THEN
    • Flag Hash as "Medium_Risk_SecOpsTI_Needs_Correlation".
    • Proceed to rb_hash_lookup_entity_chronicle.md.
  • ELSE
    • Flag Hash as "Low_Risk_SecOpsTI" (or "Info_Only_SecOpsTI").
    • Proceed to rb_hash_lookup_entity_chronicle.md.
• ELSE (output_status is "Failure"):
  • Log error: output_message.
  • Escalate: "Failed to retrieve SecOps threat intelligence for file hash {file_hash}."

---

AI Agent Execution Notes

• AI should perform NLP on secops_ti_summary for identified_keywords.
• Context from gti_confidence should inform interpretation.

---

Metrics Collection Points

• Log execution time.
• Log output_status.
• (Reference rules-bank/ai_performance_logging_requirements.md)
