SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

Linux environments often harbor persistence mechanisms that allow attackers to survive reboots. This skill provides structured detection and correlation of persistence vectors across crontab, systemd units, LD_PRELOAD hijacks, shell profile modifications, and SSH authorized_keys, enabling incident responders to build a coherent timeline.

Core Features & Use Cases

Detect and inventory persistence vectors across cron, systemd, LD_PRELOAD, and shell profiles.
Correlate findings with auditd logs to establish installation timelines.
Produce a risk-scored JSON report suitable for incident response and threat hunting.

Quick Start

Run the Linux persistence mechanism analyzer to generate a structured persistence report for the target system.

FAQPage Schema

How do I detect Linux persistence mechanisms like systemd units and LD_PRELOAD hijacks?▼

Detect Linux persistence mechanisms across crontab, systemd, LD_PRELOAD, shell profiles, and SSH keys by running an analysis script that correlates artifacts to produce a structured JSON risk report.

What is the best way to investigate shell profile modifications and SSH authorized_keys during incident response?▼

Investigate shell profile modifications and SSH authorized_keys during incident response by correlating artifacts with auditd logs to establish installation timelines and generate a risk-scored JSON report.

Do I need root access and auditd to analyze persistence vectors on Linux hosts?▼

Analyzing persistence vectors requires root or sudo access, auditd configuration, and Python 3.8+ to run the analysis script on Linux hosts, containers, or forensic images.

Can I use this approach for threat hunting on Linux containers and forensic images?▼

Use this persistence detection approach for threat hunting on Linux containers and forensic images to inventory vectors across cron and systemd, building a coherent timeline and risk profile.

How does correlating auditd logs help build a timeline for Linux persistence threats?▼

Correlating auditd logs builds a timeline for Linux persistence threats by mapping when vectors like LD_PRELOAD hijacks or shell profile modifications were installed, producing a risk-scored JSON report.
