Implementing Velociraptor for IR Collection

Overview

Velociraptor is an advanced open-source endpoint monitoring, digital forensics, and incident response platform developed by Rapid7. It uses the Velociraptor Query Language (VQL) to create custom artifacts that collect, query, and monitor almost any aspect of an endpoint. Velociraptor enables incident response teams to rapidly collect and examine forensic artifacts from across a network, supporting large-scale deployments with minimal performance impact. The client-server architecture with Fleetspeak communication enables real-time data collection from thousands of endpoints simultaneously, with offline endpoints picking up hunts when they reconnect.

When to Use

When deploying or configuring implementing velociraptor for ir collection capabilities in your environment
When establishing security controls aligned to compliance requirements
When building or improving security architecture for this domain
When conducting security assessments that require this implementation

Prerequisites

Familiarity with incident response concepts and tools
Access to a test or lab environment for safe execution
Python 3.8+ with required dependencies installed
Appropriate authorization for any testing activities

Architecture

Components

Velociraptor Server: Central management console with web UI and API
Velociraptor Client (Agent): Lightweight agent deployed to endpoints
Fleetspeak: Communication framework between client and server
VQL Engine: Query language engine for artifact collection
Filestore: Server-side storage for collected artifacts
Datastore: Metadata storage for hunts, flows, and client information

Supported Platforms

Windows (7+, Server 2008R2+)
Linux (Debian, Ubuntu, CentOS, RHEL)
macOS (10.13+)

Deployment

Server Installation

# Download latest release
wget https://github.com/Velocidex/velociraptor/releases/latest/download/velociraptor-linux-amd64

# Generate server configuration
./velociraptor-linux-amd64 config generate -i

# Start the server
./velociraptor-linux-amd64 --config server.config.yaml frontend

# Or run as systemd service
sudo cp velociraptor-linux-amd64 /usr/local/bin/velociraptor
sudo velociraptor --config /etc/velociraptor/server.config.yaml service install

Client Deployment

# Repack client MSI for Windows deployment
velociraptor --config server.config.yaml config client > client.config.yaml
velociraptor config repack --msi velociraptor-windows-amd64.msi client.config.yaml output.msi

# Deploy via Group Policy, SCCM, or Intune
# Client runs as a Windows service: "Velociraptor"

# Linux client deployment
velociraptor --config client.config.yaml client -v

# macOS client deployment
velociraptor --config client.config.yaml client -v

Docker Deployment

docker run --name velociraptor \
  -v /opt/velociraptor:/velociraptor/data \
  -p 8000:8000 -p 8001:8001 -p 8889:8889 \

Hunt Operations

Creating a Hunt

1. Navigate to Hunt Manager in Velociraptor Web UI
2. Click "New Hunt"
3. Configure:
   - Description: "IR Triage - Case 2025-001"
   - Include/Exclude labels for targeting
   - Artifact selection (e.g., Windows.Forensics.Prefetch)
   - Resource limits (CPU, IOPS, timeout)
4. Launch hunt
5. Monitor progress in real-time

VQL Hunt Examples

-- Hunt for specific file hash across all endpoints
SELECT * FROM Artifact.Generic.Detection.HashHunter(
  Hashes="e99a18c428cb38d5f260853678922e03"
)

-- Hunt for YARA signatures in memory
SELECT * FROM Artifact.Windows.Detection.Yara.Process(
  YaraRule='rule malware { strings: $s1 = "malicious_string" condition: $s1 }'
)

-- Hunt for Sigma rule matches in event logs
SELECT * FROM Artifact.Server.Import.SigmaRules()

-- Hunt for suspicious scheduled tasks
