Velociraptor

DFIR / endpoint visibility and collection platform

Velociraptor is a DFIR and endpoint visibility platform used by defenders for rapid evidence collection, hunting, and endpoint investigation workflows in authorized environments.

how-to-learn-this-tool-like-a-defender

Study the tool in layers: first what problem it solves, then how to run it safely, then how to interpret output, and finally how to combine it with other evidence. This is how beginners become reliable analysts.

$Know when the tool is the right choice (and when it is not).
$Run a safe baseline command in a lab or authorized environment.
$Interpret the output in context instead of treating it as truth by itself.
$Correlate with other evidence sources (logs, packets, assets, owner context).
$Document findings and next actions so another analyst can reproduce your work.

preflight-checklist-before-using-tool

$Confirm authorization, target scope, and acceptable impact before running commands.
$Define the question first (troubleshooting, validation, hunting, triage, remediation proof).
$Identify the evidence source you will use to confirm or challenge tool output.
$Record time, host, interface/segment, and command used so results are reproducible.
$Decide what 'normal' should look like before testing edge cases or suspicious behavior.

how-experts-read-output

$Field recognition: Which fields actually matter for the question you asked?
$Scope validation: Does this output represent the host/segment/time window you intended?
$Confidence check: Is this direct evidence, inference, or a heuristic guess?
$Correlation step: Which second source should confirm this result (logs, PCAP, ticket, CMDB, host telemetry)?
$Decision step: What action should follow (close, escalate, tune, scan deeper, validate manually)?

ethical-use-and-defense-scope

Use Velociraptor only within approved defensive scope and authorized environments, especially when it collects telemetry, touches sensitive data, or interacts with production services.

Document target scope, timing, operator, and expected impact before use. Record commands and outputs so another analyst can reproduce your workflow and validate your conclusions.

The goal is defensive learning and control validation: better detections, safer configurations, stronger policies, and clearer incident response decisions. Avoid novelty-driven use.

tool-history-origin-and-purpose

$When created: Velociraptor was introduced in the late 2010s and gained widespread DFIR adoption in the 2020s.
$Why it was created: DFIR teams needed a fast, scriptable platform for endpoint evidence collection and live investigation without ad hoc one-off scripts for every case.

It was created to support rapid, scalable endpoint collection and threat hunting with flexible artifacts and investigative workflows.

when-to-use-another-tool-or-source

!When you need host process/user context, pair with endpoint or OS logs.
!When you need ownership and business impact, pair with CMDB/ticketing/asset context.
!When the tool output is ambiguous, validate using a second evidence source before concluding.
!When production risk is high, test in a lab first and use change coordination.

1. What Velociraptor Solves for Defenders

Velociraptor is a DFIR and endpoint visibility platform used by defenders for rapid evidence collection, hunting, and endpoint investigation workflows in authorized environments.

Velociraptor fits the "DFIR / endpoint visibility and collection platform" role in this course. Treat it as one tool in a workflow, not as a complete answer by itself. The key question is what decision quality it improves for a defender.

Before using Velociraptor, define the operational question first (triage, validation, exposure review, monitoring, forensics, or documentation). Tool selection should follow the question, not the other way around.

2. Defensive Workflow and Scope Discipline

Start with authorization and scope. Document what systems, networks, datasets, or accounts are in scope for Velociraptor, along with acceptable impact and stop conditions.

Build a repeatable workflow: baseline first, collect evidence, interpret output, correlate with a second source, and document findings with next actions. This turns one-off tool use into professional practice.

Velociraptor is most effective when paired with other evidence sources such as packet data, logs, asset inventory, tickets, and owner context.

3. How to Read Output Like a Defender

Do not treat Velociraptor output as absolute truth. Validate scope (did you inspect the right host/time/window/interface?), identify the fields that matter, and note what the tool cannot tell you by itself.

Experienced defenders capture normal examples before investigating anomalies. A known-good baseline helps you explain why output is expected, suspicious, or inconclusive.

Always pair output with a follow-up decision: close, escalate, tune, patch, harden, scan deeper, collect more evidence, or update documentation/runbooks.

4. Teaching and Lab Strategy

Use Velociraptor in small labs with one clear learning goal at a time. Examples: protocol troubleshooting, password policy validation, wireless baseline building, or artifact triage.

Capture both a normal example and a failure/misuse example. The contrast is what builds expert judgment and prevents overconfidence when the tool is used under pressure.

After each lab, write a short defender report: what was observed, what evidence supports it, what remains unknown, and what control or process should improve next.

This site is a free teaching resource. Use this loop to train yourself like a working defender: ask a question, collect evidence, interpret carefully, validate, document, and repeat.

$Start with the least invasive command that can answer your question.
$Write down why you ran the command before interpreting the output.
$Treat output as evidence, not truth, until validated against another source.
$Save exact commands used so another analyst can reproduce your findings.
$Capture 'normal' examples during calm periods for future comparison.
$Escalate only after you can explain what you observed and why it matters.
