hhjkjkjkSkillhhjkjkjkSkillhunt-llm-ai
hhjkjkjk/Claude-skills/skills/hunt-llm-ai/SKILL.md
Hunt LLM/AI feature bugs — prompt injection, indirect injection, exfiltration via tool-use, ASCII smuggling, agentic AI security framework (ASI01-ASI10). Patterns: direct prompt injection in user input (bypass system prompt with 'ignore previous instructions'), indirect injection via documents/web pages the model reads, ASCII smuggling (Unicode tag block U+E0000-U+E007F invisible to humans, visible to model), tool-use exfiltration (model has fetch_url tool, attacker injects URL, model exfils chat history), system prompt extraction (manipulate model to reveal hidden instructions), training data extraction, IDOR-via-AI (model reads other-user data via system prompt confusion). Tools: chatbots, RAG endpoints, summarization, agentic copilots. Detection: any LLM-backed endpoint, document upload that triggers AI processing, autonomous agent with tools. Validate: cross-user data leak, system prompt revealed, tool-use exfil demonstrated. Use when hunting AI features, chatbots, RAG, agentic systems.
hhjkjkjkSkillhunt-mfa-bypass
hhjkjkjk/Claude-skills/skills/hunt-mfa-bypass/SKILL.md
Hunt MFA / 2FA bypass — 7 distinct patterns. (1) MFA not enforced on sensitive endpoints (password change, email change accept without MFA challenge), (2) MFA-step skip via direct navigation to post-login URL, (3) MFA-token replay (same code accepted twice), (4) brute-force the 6-digit OTP without rate limit (10^6 attempts at server speed), (5) race condition on OTP validation, (6) recovery-code dump via /api/me, (7) backup factor downgrade (SMS factor with no rate limit). Plus the chain: cookie theft + password oracle + no step-up = ATO without MFA challenge. Detection: trace auth flow in Burp, find every state transition, check if MFA is middleware-gated vs per-endpoint, check OTP entropy and rate limit on OTP-validate. Validate: attacker session reaching post-MFA state. Use when hunting auth bypass, MFA flows, chaining primitives toward ATO.

hhjkjkjkSkillhunt-ntlm-info
hhjkjkjk/Claude-skills/skills/hunt-ntlm-info/SKILL.md
Hunt NTLM/Negotiate information disclosure on internet-reachable IIS/SharePoint/Exchange. Anonymous NTLM Type-2 challenge capture leaks NetBIOS domain, internal DNS forest, computer name, AD timestamp via AV_PAIRS structure. Default Windows-installer hostnames (WIN-XXXXXXXXXXX pattern) signal lazy provisioning. Use when target advertises `WWW-Authenticate: NTLM` or `Negotiate` headers anonymously.

hhjkjkjkSkillhunt-saml
hhjkjkjk/Claude-skills/skills/hunt-saml/SKILL.md
Hunt SAML / SSO attacks. Patterns: XML Signature Wrapping (XSW1-XSW8) — modify Assertion while keeping Signature valid by relocating signed element, comment injection in NameID (admin@target.com<!--evil-->@attacker.com → some parsers see admin@target.com), signature stripping (remove Signature element entirely, server should reject but doesn't), key confusion (signed by attacker's IdP, accepted by SP), audience-restriction not validated, replay attack (same Assertion accepted twice within validity window). Tools: SAML Raider Burp extension, samlmagic, manual XML manipulation. Detection: any /saml endpoint, /Shibboleth.sso, /sso/saml/, Microsoft ADFS endpoints. Validate: account takeover via altered NameID, admin role injection via altered AttributeStatement. Real paid examples on Auth0, Okta, Microsoft, custom SAML implementations. Use when hunting SSO flows, when SAML AssertionConsumerService is reachable, when chaining IdP-trust to SP-impersonation.
hhjkjkjkSkillhunt-sharepoint

Use when target has SharePoint headers (SPRequestGuid, X-MS-InvokeApp, X-SharePointHealthScore, MicrosoftSharePointTeamServices) or paths (/_layouts/15/, /_vti_bin/, /_api/, /_catalogs/).
hhjkjkjkDeletes or force-pushesSkillhunt-sqli
hhjkjkjk/Claude-skills/skills/hunt-sqli/SKILL.md
Hunting skill for sqli vulnerabilities. Built from 12 public bug bounty reports including modern NoSQL injection (Rocket.Chat CVE-2021-22911 MongoDB $regex, Mongoose ORM CVE-2024-53900 $where bypass), modern ORM raw-fragment SQLi (Django CVE-2024-42005, Sequelize GHSA-wrh9-cjv3-2hpw), second-order SOQL injection (HackerOne Salesforce), time-based blind SQLi in GraphQL resolvers, and SQLi on OIDC-proxy backends. WAF bypass techniques include ELT() boolean/time-based substitution, CASE WHEN time-based (MySQL/MSSQL/PostgreSQL), MSSQL CHOOSE(), IIF() divide-by-zero error-based blind, volume-based oracle (OR true → response too large → 500), identifier injection (column/table name params), comment-split obfuscation, and chunked transfer encoding.

hhjkjkjkReads credentialsSkillhunt-ssti
hhjkjkjk/Claude-skills/skills/hunt-ssti/SKILL.md
Hunt server-side template injection (SSTI) across Jinja2 (Flask/Django), Twig (Symfony), Freemarker (Java), ERB (Rails), Spring, Velocity, Mako, Thymeleaf, Smarty. Detection probes use double-curly and dollar-curly math expressions evaluated server-side. Once an engine is fingerprinted, escalate to RCE via the engine-specific class-walker, callback-registrar, or Execute-utility patterns documented in disclosed reports. Detection patterns: error messages reveal engine, blank or numeric eval reveals expression mode. Targets: email templates, PDF/report generators, CMS preview features, error pages with user input. Use when hunting RCE via template rendering, when content shows engine fingerprints, when finding endpoints that compose strings with user input before render.

hhjkjkjkSkillmid-engagement-ir-detection
hhjkjkjk/Claude-skills/skills/mid-engagement-ir-detection/SKILL.md
Methodology for detecting client SOC patches, attacker activity, and security-state changes that occur DURING a red-team engagement — and converting those observations into deliverable findings. Built from authorized red-team work where the client patched a confirmed SQLi within 30 minutes of detection AND an external attacker locked multiple new accounts during a single test session. Use when (a) running ANY active engagement against a monitored target, (b) a previously-confirmed finding stops reproducing, (c) baseline timing shifts unexpectedly, or (d) you notice response patterns changing during testing.

Agent instruction files
What are agent instruction files?
Plain text files in a repository that tell a coding agent how the project works: commands to run, conventions to follow and things to avoid. CLAUDE.md, AGENTS.md, cursor rules and skills are the common kinds.
CLAUDE.md or AGENTS.md?
CLAUDE.md is read by Claude Code. AGENTS.md is an open format that Codex, Cursor and other agents read. Many projects keep one and point the other at it.
What is a skill?
A folder with a SKILL.md that describes one capability, such as filling PDFs or reviewing code. The agent loads it only when the task calls for it.
Can I search my own team's files too?
Your agents already can, over MCP, limited to the files you're allowed to read. Searching them from this page is coming.
