Para realizar un escaneo rápido en una aplicación web:
nuclei -target https://example.comNuclei puede manejar escaneos en bloque proporcionando una lista de objetivos. Puedes usar un archivo que contenga múltiples URLs.
nuclei -list urls.txtEsto escaneará toda la subred en busca de problemas relacionados con la red, como puertos abiertos o servicios mal configurados.
nuclei -target 192.168.1.0/24Para escribir y usar tu propia plantilla, crea un archivo .yaml con reglas específicas y luego úsalo como se muestra a continuación.
nuclei -u https://example.com -t /path/to/your-template.yamlPuedes ejecutar los escaneos en tu máquina y subir los resultados a la plataforma cloud para análisis y remediación adicionales.
nuclei -target https://example.com -dashboardNote
Esta funcionalidad es totalmente gratuita y no requiere suscripción. Para una guía detallada, consulta la documentación.
Las plantillas de Nuclei se basan en el concepto de archivos de plantilla YAML que definen cómo se enviarán y procesarán las peticiones. Esto aporta a nuclei capacidades de extensibilidad sencillas. Las plantillas se escriben en YAML, que especifica un formato simple y legible por humanos para definir rápidamente el proceso de ejecución.

Las Plantillas de Nuclei ofrecen una manera simplificada de identificar y comunicar vulnerabilidades, combinando detalles esenciales como clasificaciones de severidad y métodos de detección. Esta herramienta de código abierto desarrollada por la comunidad acelera la respuesta ante amenazas y es ampliamente reconocida en el mundo de la ciberseguridad. Miles de investigadores de seguridad de todo el mundo contribuyen activamente a las plantillas de Nuclei. Mantenemos dos programas para nuestros colaboradores: Pioneers y 💎 bounties.

Los escáneres de vulnerabilidades tradicionales fueron construidos hace décadas. Son de código cerrado, increíblemente lentos y dirigidos por proveedores. Los atacantes de hoy explotan masivamente CVEs recién publicadas en internet en cuestión de días, en lugar de los años que solía llevar. Este cambio requiere un enfoque completamente diferente para abordar los exploits emergentes en internet.
Construimos Nuclei para resolver este desafío. Hicimos que todo el framework del motor de escaneo fuera abierto y personalizable, permitiendo que la comunidad global de seguridad colabore y aborde los vectores de ataque y vulnerabilidades emergentes en internet. Nuclei es utilizado actualmente y recibe contribuciones de empresas Fortune 500, agencias gubernamentales y universidades.
Puedes participar contribuyendo a nuestro código, a la biblioteca de plantillas o uniéndote a nuestro equipo.
