SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires velociraptor, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps security teams quickly identify and investigate Linux-based intrusions by providing ready-to-run threat-hunting workflows using Velociraptor to surface suspicious processes, network connections, persistence mechanisms, and memory-based indicators.

Core Features & Use Cases

  • Velociraptor-based threat hunting across Linux hosts (process, network, persistence, fileless indicators).
  • Provides ATT&CK-aligned detections (T1059, T1070, T1543, T1547, T1014) in ready-to-run queries.
  • Use Case: An IR team runs quick scans to surface indicators of compromise on a compromised Linux host and then pivots to targeted investigations.

Quick Start

Run the Linux IR quick scan to generate an overview of the host security posture.

Frequently Asked Questions about linux-ir

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I hunt for Linux persistence mechanisms using Velociraptor?

This Skill hunts for Linux persistence mechanisms using Velociraptor by running ATT&CK-aligned VQL queries targeting techniques like T1543 and T1547 to surface suspicious startup scripts and kernel modules directly from host telemetry.

What is the best way to investigate suspicious network activity on a compromised Linux host?

The best way to investigate suspicious network activity on a compromised Linux host is to use this Skill's Velociraptor VQL queries, which collect and query host telemetry to surface malicious network indicators during incident response.

Do I need Velociraptor deployed to detect fileless malware on Linux?

Yes, you need Velociraptor deployed to detect fileless malware on Linux because this Skill relies entirely on Velociraptor-based workflows and VQL queries to surface memory-based indicators and fileless intrusions.

Can I use VQL queries to detect privilege abuse on Linux systems?

Yes, you can use VQL queries to detect privilege abuse on Linux systems. This Skill provides ready-to-run detection modules that query process telemetry to identify unauthorized privilege escalation and abuse.

How do I start a quick scan for indicators of compromise on a Linux endpoint?

To start a quick scan for indicators of compromise on a Linux endpoint, run the Linux IR quick scan provided by this Skill to generate an overview of the host security posture and surface suspicious processes.
