EndExt

EndExt es una herramienta en .go para extraer todos los endpoints posibles de los archivos JS

Idea

Cuando rastreas todos los archivos JS desde waybackurls por ejemplo, o incluso recolectas las URLs de los archivos JS de la página de origen de tu sitio objetivo… Si el sitio web usa un sistema de API y quieres buscar todos los endpoints en los archivos JS, porque puedes encontrar algo oculto aquí o allá… Por eso hice esta herramienta. Le paso las URLs de los archivos JS y ella captura todos los endpoints, URLs o rutas posibles de los archivos JS enviados.

Instalación

Solo necesitas instalar go, ejecuta:

▶ brew install go
▶ git clone https://github.com/SirBugs/endext.git

o descárgalo desde https://go.dev/dl/

Ten en cuenta que debes descargar el archivo regex.tmp y poner en él tu expresión regular personalizada según el archivo JS que tengas.

Patrones Regex por defecto:

"\?(.*?)"
"\/(.*?)"
'\/(.*?)'
`\/(.*?)`
this\.fetch\(this\.url\("([^"]+)"\)

Uso:

▶ go run main.go -l js_files_urls.txt
