Analyze suspected malware safely — containment, static triage, sandboxed detonation, unpacking, capability and C2 extraction, IOC production, and YARA rule authoring. Use when handed a suspicious file, hash, or sample, when triaging an alert artifact, or when producing detection content from a specimen.

# Analyzing Malware

The analysis is the easy part. The part that goes wrong is containment: a
sample detonated on a machine that can reach production, or an IOC published
that burns an active investigation. Get the environment right first.

## When to Use

- Triaging a suspicious file, attachment, script, or dropped binary
- Determining a sample's capability, persistence, and command-and-control
- Extracting indicators for hunting and blocking
- Writing YARA or behavioural detection from a specimen
- Supporting an incident with sample-derived intelligence
