linux-privilege-escalation

linux-privilege-escalation is a skill for Claude Code, Codex from Prohao42/aimy-skill. It costs 57 tokens per session (3,045 once invoked), scanned F, original, no licence file.

A testing guide for gaining higher permissions on Linux systems after obtaining a low-privilege command-line account.

In plain words
What is it for?
It covers SUID and SGID programs, Linux capabilities, scheduled tasks, kernel vulnerabilities, configuration errors, and credential collection.
Why use it?
It helps identify weaknesses that could let an attacker become the root administrator, such as unsafe settings, exposed credentials, or vulnerable software.

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

linux-privilege-escalation scanned grade F with 6 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 5d ago.

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.

Enumerates the file system for secretshighData exfiltration

Searching home directories for .env, .ssh, .aws or credential files is reconnaissance for credential theft.

find / -name "id_rsa" -o -name "*.pem" -o -name "*.key" 2>/dev/null

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

sudo LD_PRELOAD=/tmp/pe.so /usr/bin/some_allowed_binary

Reaches for credential fileshighPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

'echo "ssh-rsa AAAA..." >> /mnt/.ssh/authorized_keys'

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.

linux-privilege-escalation is a skill published in the GitHub repository Prohao42/aimy-skill (135 stars, last pushed 11d ago), with no licence file. It adds 57 tokens to every session and 3,045 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it F with 6 findings (enumerates the file system for secrets, asks for root, reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
