Analyzing Persistence Mechanisms In Linux
Guide an agent through systematic detection and analysis of Linux persistence techniques after compromise or during hardening reviews.
Overview
Analyzing Persistence Mechanisms In Linux is an agent skill most often used in Ship (also Operate) that guides systematic review of Linux persistence tradecraft for solo operators.

- Structures Linux persistence analysis for incident response and threat-hunting workflows
- Aligns with cybersecurity skill packs aimed at solo operators auditing servers and agents
- Apache 2.0 licensed material suitable for reuse in agent skill libraries
- Complements ship-phase hardening before expose-to-internet launches
- Pairs with broader anthropic-cybersecurity-skills for defense-in-depth reviews

What problem does it solve?
You cannot tell whether a Linux box is still compromised because startup hooks, timers, and keys were never reviewed methodically.
Who is it for?
Solo builders self-hosting on Linux who need a repeatable persistence checklist during security reviews or incident triage.
Skip if: Teams that only build on managed PaaS with no SSH access, or cases where you already have a completed EDR report and only need ticket closure.
When should I use this skill?
You need to analyze or document Linux persistence mechanisms during a security review, incident, or post-deploy audit.
What do I get? / Deliverables
You get a structured persistence review plan your agent can execute so residual access paths are documented and prioritized for removal.
- Prioritized list of suspicious persistence locations
- Notes tying each finding to evidence commands and remediation steps

Journey fit
Spans multiple journey phases - primary shelf plus alternate fits below.
Persistence hunting is canonical on the ship shelf because it is part of pre-release and post-incident security assurance before you trust a Linux workload in production. Security subphase fits adversary tradecraft review (cron, systemd, rc.local, SSH keys) rather than generic monitoring dashboards.
Where it fits
Before exposing an API on a VPS, run a persistence sweep so old deploy users did not leave startup hooks.
After CPU spikes from unknown processes, use the skill to map systemd timers and cron entries tied to the anomaly.
When a service restarts itself after removal, analyze rc.local, profile.d, and SSH authorized_keys for hidden restarters.
While baking a golden AMI or container base image, verify the image build pipeline did not embed persistence artifacts.
How it compares
Use as a procedural hunt playbook instead of ad-hoc shell greps or assuming a generic linter catches backdoors.
Common Questions / FAQ
Who is analyzing persistence mechanisms in linux for?
Indie developers and small teams who operate Linux servers, CLIs, or agents and need agent-guided persistence analysis without a full security operations team.
When should I use analyzing persistence mechanisms in linux?
During ship security hardening before launch, after suspicious operate-phase alerts, or when validating a recovered VPS before putting it back in production.
Is analyzing persistence mechanisms in linux safe to install?
Review the Security Audits panel on this Prism page and the upstream repo license; the bundled readme here is license text only, so verify SKILL.md and scripts before granting shell on production hosts.
