performing-password-spray-in-lab

performing-password-spray-in-lab is a skill for Claude Code, Codex from withcrux/agentHack-skills. It costs 63 tokens per session (1,591 once invoked), scanned A, original, no licence file.

A lab exercise for controlled password-spray testing against simulated login services. Password spraying tries a small number of common passwords across many accounts, rather than many passwords against one account.

In plain words
What is it for?
Testing SSH, web-login, and API authentication defenses while considering rate limits and detection.
Why use it?
It shows how this attack works and how rate limits and monitoring can detect it. The tests are intended for isolated, simulated environments.

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 A, and why

performing-password-spray-in-lab scanned grade A with 1 finding 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 11d 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.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

What ships with it

1 file 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.
