secrets

A command for extracting possible secrets and credentials from a binary by hashing it, collecting visible and obfuscated strings, and matching common credential patterns.

In plain words
What is it for?
Use it during binary analysis to find URLs, IP addresses, API keys, tokens, and similar credential-like strings.
Why use it?
Important URLs, tokens, keys, and other indicators may be hidden or encoded inside compiled software rather than visible in ordinary text searches.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 8 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 750 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

secrets scanned grade A with 0 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 2d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Secret & Credential Extraction

Parse $ARGUMENTS to get the binary path.

Step 1 — Hash & Validate

node "${CLAUDE_PLUGIN_ROOT}/scripts/binary-hasher.js" hash "$ARGUMENTS"

Step 2 — String Extraction

Run both ASCII and Unicode extraction:

strings -a -n 6 <binary>              # ASCII strings (min 6 chars)
strings -a -n 6 -el <binary>          # UTF-16 LE strings

Step 3 — Obfuscated Strings

floss <binary>                          # FLARE Obfuscated String Solver

FLOSS will extract stack strings, tight strings, and decoded strings that strings misses.

Step 4 — Pattern Matching

Apply regex patterns to all extracted strings:

Pattern Type Example
https?://[^\s"']+ url http://c2.evil.com/beacon
\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3} ip 192.168.1.100
AKIA[0-9A-Z]{16} api-key AWS Access Key
AIza[0-9A-Za-z_-]{35} api-key GCP API Key
eyJ[A-Za-z0-9_-]+\.eyJ[A-Za-z0-9_-]+ token JWT Token
[a-zA-Z0-9+/]{40,}={0,2} credential Base64 encoded blob
-----BEGIN .* KEY----- crypto-key PEM private key
HKEY_(LOCAL_MACHINE|CURRENT_USER)\\.* registry-key Registry path
[13][a-km-zA-HJ-NP-Z1-9]{25,34} wallet Bitcoin address
password\s*[=:]\s*\S+ credential Hardcoded password
(user|admin|login)\s*[=:]\s*\S+ credential Username/credential
Data Source=.* credential Connection string

Step 5 — Base64 Decode

For each base64 blob found, decode and inspect:

echo "<blob>" | base64 -d 2>/dev/null

Look for decoded URLs, commands, scripts, or binary data.

Step 6 — Log Findings

For each unique finding:

node "${CLAUDE_PLUGIN_ROOT}/scripts/findings-tracker.js" add "<binary>" "<type>" "<value>" "<severity>" "<title>"

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.

secrets is a command published in the GitHub repository ogrodev/fsociety (20 stars, last pushed 5mo ago), licensed MIT. It adds 8 tokens to every session and 750 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
