linux-lateral-movement

linux-lateral-movement is a skill for Claude Code, Codex from Prohao42/aimy-skill. It costs 48 tokens per session (3,350 once invoked), scanned F, original, no licence file.

A testing guide for moving from one Linux computer to other systems after gaining an initial foothold.

In plain words
What is it for?
It covers SSH session hijacking, credential collection, internal network pivoting, D-Bus attacks, reused sudo tokens, and shared-filesystem abuse.
Why use it?
It helps assess how stolen credentials, reused sessions, shared files, or internal connections could let an attacker spread through a network.

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-lateral-movement 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 6d 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 "id_ed25519" -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.

Linux lateral movement playbook. Use after gaining initial access to pivot across Linux hosts via SSH hijacking, credential harvesting, internal pivoting, D-Bus exploitation, sudo token reuse, and shared filesystem abuse

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.

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-lateral-movement is a skill published in the GitHub repository Prohao42/aimy-skill (135 stars, last pushed 12d ago), with no licence file. It adds 48 tokens to every session and 3,350 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it F with 4 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.
