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+)

API Reference: Velociraptor Incident Response Collection

Libraries Used

Library Purpose
pyvelociraptor Official Python bindings for Velociraptor gRPC API
grpc gRPC transport for API communication
json Parse VQL query results
yaml Read Velociraptor API config files

Installation

pip install pyvelociraptor grpcio pyyaml

Authentication

Velociraptor uses mTLS with an API config file generated by the server:

import pyvelociraptor
import json
import os

# Generate API config on the Velociraptor server:
# velociraptor config api_client --name analyst > api_client.yaml

config_path = os.environ.get("VELOCIRAPTOR_API_CONFIG", "api_client.yaml")

gRPC API — Query Method

The primary API method is Query(), which executes VQL (Velociraptor Query Language) statements:

import pyvelociraptor
import json

def run_vql(config_path, query):
    config = pyvelociraptor.LoadConfigFile(config_path)
    grpc_channel = pyvelociraptor.grpc_channel(config)
    stub = pyvelociraptor.api_pb2_grpc.APIStub(grpc_channel)

    request = pyvelociraptor.api_pb2.VQLCollectorArgs(
        max_wait=10,
        max_row=1000,
        Query=[pyvelociraptor.api_pb2.VQLRequest(
            VQL=query,
        )],
    )

    results = []
    for response in stub.Query(request):
        if response.Response:
            rows = json.loads(response.Response)
            results.extend(rows)
    return results

Common VQL Queries

List Connected Clients

clients = run_vql(config_path, """
    SELECT client_id, os_info.hostname as hostname,
           os_info.system as os, last_seen_at
    FROM clients()
    WHERE last_seen_at > now() - 3600
""")

Collect Artifacts from an Endpoint

# Start a collection (hunt) on a specific client
collection = run_vql(config_path, """
    SELECT collect_client(
        client_id='C.abc123def456',
        artifacts=['Windows.KapeFiles.Targets'],
        parameters=dict(Device='C:', VSSAnalysis='Y')
    ) FROM scope()
""")
flow_id = collection[0]["collect_client"]["flow_id"]

Monitor Collection Status

status = run_vql(config_path, f"""
    SELECT * FROM flows(client_id='C.abc123def456')
    WHERE session_id = '{flow_id}'
""")
# Fields: state, create_time, total_collected_rows, total_uploaded_bytes

Retrieve Flow Results

results = run_vql(config_path, f"""
    SELECT * FROM flow_results(
        client_id='C.abc123def456',
        flow_id='{flow_id}',
        artifact='Windows.KapeFiles.Targets'
    )
""")

Hunt Across All Clients

hunt = run_vql(config_path, """
    SELECT hunt(
        description='Search for suspicious scheduled tasks',
        artifacts=['Windows.System.TaskScheduler'],
        parameters=dict()
    ) FROM scope()
""")
hunt_id = hunt[0]["hunt"]["hunt_id"]

Search for IOCs Across Fleet

ioc_results = run_vql(config_path, """
    SELECT * FROM hunt_results(hunt_id='H.abc123')
    WHERE OSPath =~ 'mimikatz|lazagne|rubeus'
""")
