acidrain-security-testing-scripts

acidrain-security-testing-scripts is a skill for Claude Code, Codex from Aradotso/security-skills. It costs 35 tokens per session (4,469 once invoked), scanned C, original, no licence file.

A set of scripts for web-security learning and authorized testing, focused on cross-site scripting (XSS), JavaScript utilities, and PHP injection samples. XSS can run unwanted scripts in a visitor’s browser, while injection attacks send harmful input into a website.

In plain words
What is it for?
Use it to analyse XSS, work with JavaScript utilities, test PHP injection handling, and learn through hands-on exercises.
Why use it?
It offers ready-made examples and utilities for practising common web-security checks.

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 C, and why

acidrain-security-testing-scripts scanned grade C 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 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.

Sends data to an external URLlowData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

curl -s -X POST -d "${PARAM}=${ENCODED}" "$TARGET" | grep -o "$PAYLOAD" && echo "[!] Reflected!" || echo "[*] Not reflected"

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Asks for rootlowPrivilege escalation

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

- Ensure proper file permissions: `chmod 644 script.php`

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Encoded or obfuscated payloadmediumSupply chain

base64 or hex that is decoded and executed hides what actually runs from anyone reading the file.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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 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.
