privesc-linpeas

A Linux privilege-escalation assessment toolkit built around LinPEAS, a script that searches a system for ways a low-privilege user might gain more access.

In plain words
What is it for?
It is for post-exploitation checks on Linux systems, including finding privilege-escalation paths, misconfigurations, and credential exposure.
Why use it?
It automates the search for configuration mistakes, exposed credentials, and other escalation paths after access has been obtained.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade F, and why

privesc-linpeas scanned grade F with 4 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/linpeas_runner.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

privesc-linpeas is a skill published in the GitHub repository AgentSecOps/SecOpsAgentKit (202 stars, last pushed 4mo ago), with no licence file. It adds 153 tokens to every session and 2,307 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it F with 4 findings (asks for root, reaches for credential files, downloads and executes remote code). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
