The Triage Workflow

What is it?

Triage is the fast first pass that decides how much analysis a sample needs and in what order: identify the file type, hash it and check what is already known, run quick static checks (strings, imports), and only then decide whether deep static or dynamic analysis is warranted.

Why it matters

Analysis time is scarce and samples are many. Triage aims the expensive deep analysis at the samples that need it, and resolves the easy ones (known-good, known-bad) in minutes.

Where you see it

The intake queue of every malware desk: each sample triaged before anyone commits hours to it.

What normal looks like

A triage note per sample: type, hash, known/unknown, quick static observations, and a recommended depth.

What suspicious looks like

Not applicable directly — triage is workflow, not a verdict.

How analysts investigate

By running the same short checklist on every sample and escalating to deep analysis only where triage found reason to.

Common beginner mistakes

  • Jumping straight to detonation on every sample — deep dynamic analysis on a sample a hash lookup would have resolved in ten seconds wastes the scarce resource triage exists to protect.

Triage runs cheap safe static checks first, and reserves detonation for samples that earn it.

Quick check

A submitted sample's hash matches a well-known, already-analyzed malware family in your intel. What does triage conclude?
