name	malware-reverse-engineering
description	Malware reverse engineering and suspicious artifact analysis skill for defensive triage, static analysis, dynamic analysis planning, unpacking strategy, indicators of compromise, behavior summaries, YARA/Sigma ideas, and remediation guidance. Use for suspicious binaries, scripts, documents, logs, memory artifacts, sandbox reports, and malware family analysis in isolated environments.

Malware Reverse Engineering

Safety Boundary

• Treat samples as hostile. Use isolated labs, snapshots, no shared clipboard, no mounted personal directories, and controlled networking.
• Do not provide malware improvement, persistence, stealth, evasion, credential theft, or deployment guidance.
• Focus on behavior, indicators, detection, containment, and eradication.

Workflow

1. Record sample metadata: filename, hashes, size, type, source, timestamp, and handling notes.
2. Perform static triage: strings, imports, sections, packer hints, scripts/macros, config blobs, and suspicious capabilities.
3. Plan dynamic analysis with containment: VM snapshot, fake services, monitored filesystem/registry/process/network activity.
4. Summarize behavior by capability: execution, persistence, privilege, defense evasion, discovery, C2, collection, exfiltration.
5. Produce IOCs, detection logic ideas, remediation steps, and confidence levels.

Output Format

• Summary: what the artifact appears to do.
• Evidence: strings, APIs, paths, domains, mutexes, commands, or observed events.
• IOCs: hashes, filenames, registry keys, network indicators, and caveats.
• Detections: YARA/Sigma/EDR hunting ideas where appropriate.
• Response: containment, eradication, recovery, and monitoring.
