SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Security analysts need a consistent, repeatable process for triaging suspected malicious file hashes found in alerts, without performing full reverse engineering or deep forensics on every detection. ## Core Features & Use Cases - Threat Intelligence Enrichment: Retrieves GTI file reports and sandbox behavior summaries, including malware family classification, contacted IPs/domains, and MITRE TTPs. - SIEM Impact Scoping: Searches security events for process launches, file modifications, and network connections tied to the hash to identify affected hosts and users. - SOAR Documentation & Reporting: Posts synthesized findings and recommendations to the SOAR case and optionally generates a Markdown report with a Mermaid diagram. - Use Case: An alert fires on a suspicious SHA256 hash. Provide the hash and case ID, and the runbook enriches it via GTI, scopes executions in the SIEM, checks related open cases, and documents a severity assessment with containment recommendations. ## Quick Start Triage the file hash d41d8cd98f00b204e9800998ecf8427e associated with SOAR case 1234 and document the findings in the case.

Frequently Asked Questions about malware-triage

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I triage a suspicious file hash with GTI and SIEM?▼

Provide the MD5, SHA1, or SHA256 hash along with a SOAR case ID. The runbook retrieves the GTI file report and behavior summary, searches SIEM events for executions and network activity, then documents an assessment in the case.

What tools does malware triage use for threat intelligence?▼

It uses gti-mcp tools including get_file_report, get_file_behavior_summary, and entity relationship lookups for contacted IPs and domains. SIEM searches run through secops-mcp search_security_events and lookup_entity.

Does this runbook perform reverse engineering or forensic analysis?▼

No. The scope is limited to initial triage using GTI and SIEM data. It explicitly excludes full reverse engineering and deep host forensics, recommending escalation to Tier 3 or IR teams when deeper analysis is needed.

What inputs are required to run malware triage?▼

You need the file hash (MD5, SHA1, or SHA256), the SOAR case ID, and alert group identifiers. An optional TIME_FRAME_HOURS parameter controls the SIEM lookback window, defaulting to 72 hours.

When should I escalate instead of closing a malware alert?▼

Escalate when GTI classifies the file as malicious, sandbox behavior shows suspicious TTPs, or SIEM reveals executions across multiple hosts. The runbook recommends host isolation, IOC blocking, or Tier 3 escalation based on synthesized findings.
