nullmap

nullmap Un mapeador de controladores manual muy simple basado en mi anterior voidmap y CVE-2023-21768 POC por chompie y b33f. Debido a que la primitiva subyacente de lectura/escritura de memoria de post-explotación de IoRing no maneja muchas lecturas y escrituras consecutivas muy bien, decidí...

Smap

alternativa a nmap impulsada por shodan.io Smap es un escáner de puertos pasivo construido con la API gratuita de shodan.io. Acepta los mismos argumentos de línea de comandos que Nmap y produce la misma salida, lo que lo convierte en un sustituto directo de Nmap. Características Escanea 200 hosts...
