default-credentials

default-credentials is a skill for Claude Code, Codex from ShulkwiSEC/bb-huge. It costs 99 tokens per session (1,539 once invoked), scanned A, original, MIT.

A security testing guide for finding default usernames, weak passwords, and poorly protected login pages in websites, content-management systems, and device interfaces.

In plain words
What is it for?
Use it to assess admin panels, CMS installations such as WordPress, and embedded-device management pages for weak authentication controls.
Why use it?
It helps reveal accounts that attackers could enter using published defaults, common passwords, password guessing, or credential reuse.

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

default-credentials 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 7d 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.

Default and Weak Credentials

What Is Broken and Why

Web applications, CMS platforms, and network devices ship with documented default credentials that administrators frequently fail to change. Weak password policies that permit short, common, or non-complex passwords compound the risk by allowing brute-force and credential-stuffing attacks to succeed rapidly. When combined with exposed admin paths discovered through fingerprinting, the attack chain from reconnaissance to authenticated access can be trivially short.

Key Signals

  • Admin path accessible: /wp-admin/, /administrator/, /admin/, /manager/, /console/
  • Framework identified via cookie names, headers, or meta tags (WordPress, Joomla, Drupal, etc.)
  • Login form accepts admin/admin, admin/password, admin/<blank>, root/root
  • Password policy accepts "Password1" or "123456" on registration/change
  • No account lockout after repeated failed attempts
  • No rate limiting or CAPTCHA on login endpoint
  • Error messages distinguish between invalid username and invalid password (username enumeration)
  • HTTP Basic Auth realm on admin endpoints

Methodology

  1. Fingerprint the platform: Identify CMS/framework via headers, cookies, HTML markers, and path probing (see web-fingerprinting skill).
  2. Locate login endpoint: Check /robots.txt Disallow entries; dirbust with framework-specific wordlist; follow redirects from root path.
  3. Check for lockout and rate limiting: Submit 5-10 intentionally wrong credentials; observe whether account locks or responses slow.
  4. Username enumeration: Test error message differentiation between unknown user and wrong password.
  5. Default credential test: Try documented defaults for identified platform.
  6. Weak password spray: Test a short list of common passwords against discovered usernames (low-and-slow to avoid lockout).
  7. Password policy audit: Attempt to register or change password to weak values; document what is and is not accepted.
