SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) and assets (resource) components.

What problem does it solve? Security analysts need to turn scattered public threat intelligence—hashes, IOCs, sandbox reports, and vendor write-ups—into a traceable, evidence-graded assessment of a malware family without ever handling live samples. This Skill structures that research workflow and separates confirmed facts from speculation. ## Core Features & Use Cases - Family and IOC Analysis: Normalizes malware family names and aliases, validates and deduplicates IOCs, and maps observed behavior to MITRE ATT&CK techniques with evidence and confidence levels. - Evidence-Graded Reporting: Produces a fixed-structure report covering infection chain, ATT&CK mapping, IOC freshness and false-positive risk, detection hypotheses, alternative explanations, and prioritized response actions. - Taiwan Financial Sector Module: Loads a dedicated reference when the analysis involves Taiwanese banks, insurers, or securities firms, adding industry-specific exposure analysis and compliance checkpoints. - Use Case: A SOC analyst receives a SHA256 hash flagged in an alert. The Skill cross-checks public sources like MalwareBazaar and URLhaus, identifies the likely family and its ATT&CK techniques, and delivers detection hunting ideas plus a 24-hour and 7-day action plan. ## Quick Start Analyze this malware family and its IOCs using only public threat intelligence, then provide detection and response recommendations for a Taiwan financial institution.

Frequently Asked Questions about malware-research-analysis

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

FAQPage Schema
How do I analyze a malware family from a file hash?▼

Provide the SHA256 or MD5 hash along with your analysis goal. The Skill queries public metadata services like MalwareBazaar for family labels, timestamps, and public IOCs, then reconstructs behavior and ATT&CK mappings from credible technical reports without downloading the sample.

What sources are used for malware threat intelligence research?▼

Sources include MITRE ATT&CK, CISA, CERT reports, MalwareBazaar, URLhaus, ThreatFox, Feodo Tracker, and official SigmaHQ and YARA rule repositories. Time-sensitive facts are verified online, and major judgments require at least one independent cross-validating source.

Can this analyze an actual malware sample file I upload?▼

No. The Skill never downloads, extracts, opens, executes, or uploads unknown files. If you have a suspected sample, run it through your organization's approved sandbox or forensics process first, then provide the sanitized text report for analysis.

How are IOCs handled to avoid accidental exposure?▼

IOCs are validated, deduplicated, and annotated with freshness, source, confidence, false-positive risk, and expiry recommendations. Malicious domains and URLs are defanged using formats like hxxps:// or example[.]com so they cannot be clicked accidentally.

Does it support analysis specific to Taiwan financial institutions?▼

Yes. A dedicated reference module loads when the task involves Taiwanese banks, insurers, securities firms, or financial supply chains. It adds industry-specific exposure analysis, internal telemetry recommendations, and compliance items flagged for verification against current official regulations.

What are the limitations of public-source malware analysis?▼

Public data cannot confirm internal compromise; only your own EDR, SIEM, DNS, or IAM telemetry can. Attribution remains speculative without multiple evidence types, and the Skill explicitly labels unverified claims and lists alternative explanations rather than filling gaps with assumptions.
