Source documentation, not instructions for this website. Review permissions before running any commands.
references/secret-regexes.md, references/error-signatures.md, references/directory-signatures.mdOnly run against a web application the user owns or is contractually engaged to test. This skill has two halves, each labelled by blast radius:
Take inputs as whatever you already hold: captured responses/requests for the passive half, and the target's domains / domain:port pairs for the active half. Report a finding exactly where each section says "Report a finding when...".
Each class is one pass over the capture; each yields per-target findings.
Work through the given scope of the target, and work to maximize all the attack surface expansion via all techniques that comes to mind.
Take a webapp for example - seeing a 404 is one thing, but subdomain enumeration expanding the targets, on each running available browser tools to get extended sitemap, available source code, backup files, flush errors and stack traces with unexpected inputs and more.
Coverage is most important as you have to invent and act on lots of variations per the target type tailored to any customization opportunity you may discover that can further the search (e.g. if its next.js version xyz do we know how to trigger errors on there).
For every captured response, case-insensitively collect the response header names and report each of the ten headers below that is absent. Report a finding when: a response is missing any of these. Remediation is "add the <Header> in responses returning from the server".
| Header | Why it matters |
|---|---|
| X-Frame-Options | Blocks embedding the site in iframes (clickjacking). |
| Content-Security-Policy | Controls which resources (e.g. JS) the page may load. |
| Strict-Transport-Security | Forces HTTPS, including on the initial HTTP connection. |
| Permissions-Policy | Disables specific browser APIs; propagates to iframes. |
| X-Content-Type-Options | Stops MIME sniffing; browser trusts only the declared Content-Type. |
| Referrer-Policy | Prevents leaking sensitive query params via the Referer to third parties. |
| Cross-Origin-Resource-Policy | (xs-leaks) Restricts cross-origin access to the document's resources. |
| Cross-Origin-Embedder-Policy | (xs-leaks) Blocks loading cross-origin resources that don't grant permission via CORP/CORS. |
| Cross-Origin-Opener-Policy | (xs-leaks) Stops popup/opener documents from reaching the page's global object. |
| Cache-Control | Prevents responses being cached in intermediary proxies and leaked to other users. |
Look only at cookies that look session-bearing - the cookie name (case-insensitive) contains sess or token. For each such Set-Cookie with a non-empty value, report a finding when any of:
; or no =. The whole cookie is insecure.HttpOnly - Cookie '<name>' doesn't have the HTTPOnly attribute set. Fix: set HttpOnly on important cookies.Secure - Cookie '<name>' doesn't have the Secure attribute set. Fix: set Secure.SameSite=None - Cookie '<name>' has the SameSite attribute set to 'none'. Fix: set SameSite=Strict, or at least Lax.Expires (parsed as a unix timestamp here) more than 14 days out. Cookie '<name>' has a long expiration date set of more than N days. Fix: give important cookies a short-lived expiration.Non-session cookies (no sess/token in the name) and empty-valued cookies are skipped to keep the signal high.
Run the secret-regex set in references/secret-regexes.md over every captured response body. Report an INSIGHT (not a hard finding - these are high-value leads that need confirmation) when: any pattern matches. Record <secret name> ( <matched value(s)> ) while requesting <paths>; de-duplicate matches per target and truncate the joined match string to 400 chars.
The set (~40 patterns) covers provider credentials and identifiers: OpenAI/sk-, Slack tokens/webhooks, GitHub classic/fine-grained PATs and git+https URIs, AWS access-key IDs / MWS tokens / S3 bucket URLs, Google API keys / OAuth / GCP service-account JSON / ya29. access tokens, Stripe/Square/PayPal Braintree/Picatic/Mailgun/MailChimp payment & mail keys, DigitalOcean, HuggingFace, Grafana Cloud, Segment, Okta, Fullstory, Adobe, Heroku, Telegram, Firebase URLs, and a generic "Password": "..." JSON pattern. Full patterns in the reference file.
Secrets in third-party JS may be intentional publics (e.g. a Google Maps browser key) - verify before reporting as a leak; treat the finding as a lead.
Run the error-signature set in references/error-signatures.md over every captured response body. First skip responses that are JavaScript bundles (they produce false positives): skip the body if it matches sourceMappingURL|window\.addEventListener|window\.document|webpackJsonp|jQuery. Report a finding when: any signature matches; record <signature name> ( <match> ) while requesting <paths>.
The set (~130 signatures) spans: SQL/DB errors (MySQL, MSSQL OLE DB, PostgreSQL, Oracle ORA-, DB2, SQLite, MongoDB E11000, Elasticsearch mapper_parsing_exception); language runtime exceptions (Java java.lang.*/java.io.*/java.sql.*, Python Traceback/ValueError/KeyError/etc., Ruby, C++ std::*, .NET System.*); framework error pages (Django, Flask/Werkzeug, Laravel/Symfony, Spring/Spring Boot/Hibernate, Rails ActionView::Template::Error, Express.js, ASP.NET "Server Error in '/' Application"); insecure-deserialization gadget-chain traces (Java ObjectInputStream.readObject, InvokerTransformer/LazyMap/ChainedTransformer, readObject/writeObject, Python pickle/yaml.load, Ruby Marshal.load/YAML.load, PHP unserialize(, C# BinaryFormatter, Go encoding/gob, Jackson); config/secret disclosure (<compilation debug="true", DATABASES = {...}, secret_key_base, Web.config, Node config errors); and CSRF/JWT errors. Full name+pattern table in the reference file.
Because this is a passive body-string search (not endpoint probing), the patterns are deliberately precise. Run over every captured response body; report an INSIGHT when any matches (<name> ( <match> ) while requesting <paths>). This is the passive counterpart to the active port probe in check 8 - a passive hit tells you where to point check 8.

Over captured requests, inspect query-string params and body params (parsed by Content-Type: XML tags, JSON keys, or x-www-form-urlencoded keys). Report an INSIGHT when: a parameter key matches the RCE-suggestive wordlist below, or a parameter value equals ##class (a common template/gadget marker). Record which location matched, e.g. Query parameter key 'cmd' was found at path '<path>' or JSON body parameter key 'exec' was found at path '<path>'. These names don't prove a vuln - they flag parameters worth targeted, authorized command-injection testing.
Parameter keys (case-sensitive match, as captured):
daemon, execute, cmd, cli, ip, xp_cmdshell, CSPCHD, exec, func, function,
command, eval, shell, shell_exec, popen, proc_open, bash, python, system,
payload, cmdline, exe, execcommand, exec_code, exec_cmd, executeshell,
cmd_exec, cmd_inject, cmd_shell, cmd_script, run, runcmd, runcommand,
shellcode, shellexec, shellcmd, command_prompt, process, terminal,
execute_command, exec_file, load_module, load_script, proc_cmdline,
runtime_exec, shell_execute, system_command, sys_command
Parameter values: ##class.
Requests with a body but no Content-Type, or an unrecognized Content-Type, are skipped.
These send live requests. Confirm scope first; they leave logs on the target (and, for 9-10, on third parties).
For each domain, GET a curated set of source/config/log/known-CVE paths (no redirects, TLS verification off, 10s). Each signature carries a path, an expected status regex and a body regex; a match must satisfy both. The full 26-signature table lives in references/directory-signatures.md (e.g. /.git/config, /.git/config~, /.git, /.svn, /package.json, /jsconfig.json, /config.json, /info.php, /phpinfo.php, /web.config, /global.asa, /storage/logs/laravel.log, /wp-content/debug.log, Eclipse Jetty /WEB-INF/web.xml and its /%2e/-prefixed traversal variant, Telerik /Telerik.Web.UI.WebResource.axd?type=rau, Pulse /dana-na/, /adminer.php, /phinx.yml, and Django-debug /djgo expecting a 4xx page containing DEBUG =).
False-positive controls (essential - catch-all responders are common):
404 Not Found or This page can't be displayed.Report a finding when: at least one - but not all - signatures match after dedup. Severity: Information Disclosure (rate individually; exposed .git/.svn or a live source/config/log file is often high impact).
For each domain, probe management interfaces of RCE-prone stacks across their typical ports, matching a substring in the response body. Cache each port's response and reuse it so overlapping port lists don't re-request. On

## Scope & authorization
Only run against a web application the user owns or is contractually engaged to test. This skill has two halves, each labelled by blast radius:
- **Passive (classes 1-6)** - inspects responses and requests you already captured (proxy history, an authenticated crawl, a saved sitemap, files on disk). Sends **no new HTTP requests**, mutates nothing, and is safe against a frozen capture.
- **Active (checks 7-10)** - sends live requests to the target and, for Wayback (9) and dependency confirmation (10), to third-party services (the Internet Archive, the npm registry). Check 8 is **aggressive** (multi-port sweep). Run these only in scope, and prefer a low-traffic window.
Take inputs as whatever you already hold: captured responses/requests for the passive half, and the target's domains / `domain:port` pairs for the active half. Report a finding exactly where each section says "Report a finding when...".
## Passive analysis of captured traffic
Each class is one pass over the capture; each yields per-target findings.
### 0. Extensive attack surface flushout and coverage
Work through the given scope of the target, and work to maximize all the attack surface expansion via all techniques that comes to mind.
Take a webapp for example - seeing a 404 is one thing, but subdomain enumeration expanding the targets, on each running available browser tools to get extended sitemap, available source code, backup files, flush errors and stack traces with unexpected inputs and more.
Coverage is most important as you have to invent and act on lots of variations per the target type tailored to any customization opportunity you may discover that can further the search (e.g. if its next.js version xyz do we know how to trigger errors on there).
### 1. Missing or weak security headers
For every captured response, case-insensitively collect the response header names and report each of the ten headers below that is absent. Report a finding when: a response is missing any of these. Remediation is "add the `<Header>` in responses returning from the server".
| Header | Why it matters |
|---|---|
| X-Frame-Options | Blocks embedding the site in iframes (clickjacking). |
| Content-Security-Policy | Controls which resources (e.g. JS) the page may load. |
| Strict-Transport-Security | Forces HTTPS, including on the initial HTTP connection. |

| Cache-Control | Prevents responses being cached in intermediary proxies and leaked to other users. |
### 2. Insecure session cookies
Look only at cookies that look session-bearing - the cookie **name** (case-insensitive) contains `sess` or `token`. For each such `Set-Cookie` with a non-empty value, report a finding when any of:
- **No attributes at all** - the cookie string has no `;` or no `=`. The whole cookie is insecure.
- **Missing `HttpOnly`** - `Cookie '<name>' doesn't have the HTTPOnly attribute set`. Fix: set HttpOnly on important cookies.
- **Missing `Secure`** - `Cookie '<name>' doesn't have the Secure attribute set`. Fix: set Secure.
- **`SameSite=None`** - `Cookie '<name>' has the SameSite attribute set to 'none'`. Fix: set SameSite=Strict, or at least Lax.
- **Long lifetime** - an `Expires` (parsed as a unix timestamp here) more than **14 days** out. `Cookie '<name>' has a long expiration date set of more than N days`. Fix: give important cookies a short-lived expiration.
Non-session cookies (no `sess`/`token` in the name) and empty-valued cookies are skipped to keep the signal high.
### 3. Hardcoded secrets & API tokens in bodies
Run the secret-regex set in `references/secret-regexes.md` over every captured response body. Report an INSIGHT (not a hard finding - these are high-value leads that need confirmation) when: any pattern matches. Record `<secret name> ( <matched value(s)> ) while requesting <paths>`; de-duplicate matches per target and truncate the joined match string to 400 chars.
The set (~40 patterns) covers provider credentials and identifiers: OpenAI/`sk-`, Slack tokens/webhooks, GitHub classic/fine-grained PATs and `git+https` URIs, AWS access-key IDs / MWS tokens / S3 bucket URLs, Google API keys / OAuth / GCP service-account JSON / `ya29.` access tokens, Stripe/Square/PayPal Braintree/Picatic/Mailgun/MailChimp payment & mail keys, DigitalOcean, HuggingFace, Grafana Cloud, Segment, Okta, Fullstory, Adobe, Heroku, Telegram, Firebase URLs, and a generic `"Password": "..."` JSON pattern. Full patterns in the reference file.
Secrets in third-party JS may be intentional publics (e.g. a Google Maps browser key) - verify before reporting as a leak; treat the finding as a lead.
### 4. Improper error handling - stack traces, DB errors, debug pages
Run the error-signature set in `references/error-signatures.md` over every captured response body. **First skip responses that are JavaScript bundles** (they produce false positives): skip the body if it matches `sourceMappingURL|window\.addEventListener|window\.document|webpackJsonp|jQuery`. Report a finding when: any signature matches; record `<signature name> ( <match> ) while requesting <paths>`.
The set (~130 signatures) spans: SQL/DB errors (MySQL, MSSQL OLE DB, PostgreSQL, Oracle `ORA-`, DB2, SQLite, MongoDB `E11000`, Elasticsearch `mapper_parsing_exception`); language runtime exceptions (Java `java.lang.*`/`java.io.*`/`java.sql.*`, Python `Traceback`/`ValueError`/`KeyError`/etc., Ruby, C++ `std::*`, .NET `System.*`); framework error pages (Django, Flask/Werkzeug, Laravel/Symfony, Spring/Spring Boot/Hibernate, Rails `ActionView::Template::Error`, Express.js, ASP.NET "Server Error in '/' Application"); **insecure-deserialization** gadget-chain traces (Java `ObjectInputStream.readObject`, `InvokerTransformer`/`LazyMap`/`ChainedTransformer`, `readObject`/`writeObject`, Python `pickle`/`yaml.load`, Ruby `Marshal.load`/`YAML.load`, PHP `unserialize(`, C# `BinaryFormatter`, Go `encoding/gob`, Jackson); config/secret disclosure (`<compilation debug="true"`, `DATABASES = {...}`, `secret_key_base`, Web.config, Node config errors); and CSRF/JWT errors. Full name+pattern table in the reference file.
### 5. Outdated / dev-mode technology fingerprints
Because this is a passive body-string search (not endpoint probing), the patterns are deliberately precise. Run over every captured response body; report an INSIGHT when any matches (`<name> ( <match> ) while requesting <paths>`). This is the passive counterpart to the active port probe in check 8 - a passive hit tells you where to point check 8.

Reference: nuclei-templates `http/cves/2019/CVE-2019-11510.yaml`.
### 6. RCE-prone parameters in captured requests
Over captured **requests**, inspect query-string params and body params (parsed by Content-Type: XML tags, JSON keys, or `x-www-form-urlencoded` keys). Report an INSIGHT when: a parameter **key** matches the RCE-suggestive wordlist below, or a parameter **value** equals `##class` (a common template/gadget marker). Record which location matched, e.g. `Query parameter key 'cmd' was found at path '<path>'` or `JSON body parameter key 'exec' was found at path '<path>'`. These names don't prove a vuln - they flag parameters worth targeted, authorized command-injection testing.
Parameter keys (case-sensitive match, as captured):
```
daemon, execute, cmd, cli, ip, xp_cmdshell, CSPCHD, exec, func, function,
command, eval, shell, shell_exec, popen, proc_open, bash, python, system,
payload, cmdline, exe, execcommand, exec_code, exec_cmd, executeshell,
cmd_exec, cmd_inject, cmd_shell, cmd_script, run, runcmd, runcommand,
shellcode, shellexec, shellcmd, command_prompt, process, terminal,
execute_command, exec_file, load_module, load_script, proc_cmdline,
runtime_exec, shell_execute, system_command, sys_command
```
Parameter values: `##class`.
Requests with a body but no Content-Type, or an unrecognized Content-Type, are skipped.
## Active probing of the live target
These send live requests. Confirm scope first; they leave logs on the target (and, for 9-10, on third parties).
### 7. Disclosure-path brute - *active*
For each domain, GET a curated set of source/config/log/known-CVE paths (no redirects, TLS verification off, 10s). Each signature carries a path, an expected **status regex** and a **body regex**; a match must satisfy both. The full 26-signature table lives in `references/directory-signatures.md` (e.g. `/.git/config`, `/.git/config~`, `/.git`, `/.svn`, `/package.json`, `/jsconfig.json`, `/config.json`, `/info.php`, `/phpinfo.php`, `/web.config`, `/global.asa`, `/storage/logs/laravel.log`, `/wp-content/debug.log`, Eclipse Jetty `/WEB-INF/web.xml` and its `/%2e/`-prefixed traversal variant, Telerik `/Telerik.Web.UI.WebResource.axd?type=rau`, Pulse `/dana-na/`, `/adminer.php`, `/phinx.yml`, and Django-debug `/djgo` expecting a **4xx** page containing `DEBUG =`).
**False-positive controls (essential - catch-all responders are common):**
- Drop any response whose body contains `404 Not Found` or `This page can't be displayed`.
- Hash (MD5) each matching response body; collapse duplicates so one generic page counted many times becomes one hit.
- If **every** signature matches (hit count == number of signatures), discard the whole domain - the server answers 200 to everything and none of it is real.
**Report a finding when**: at least one - but not all - signatures match after dedup. Severity: Information Disclosure (rate individually; exposed `.git`/`.svn` or a live source/config/log file is often high impact).
### 8. Outdated / vulnerable software port probe - *aggressive*
For each `domain`, probe management interfaces of RCE-prone stacks across their typical ports, matching a substring in the response body. Cache each port's response and reuse it so overlapping port lists don't re-request. OnSkill source recorded
