La comunidad ciber se ha puesto manos a la obra. Si detectáis cualquier tipo de bulo, scam, estafa relacionado con la DANA podéis comentarlo aquí o dejar cualquier investigación que hayáis hecho.

Muchas gracias a @cibernicola_es y a @TFujiwara86 por la propuesta

Pues mira, propongo a la comunidad ciber algo yo también:
Estad al loro de los fraudes/scams relacionados con la DANA, si veis cualquier cosa, comentad (internamente), indagad, recabad información, reventad, repetid.

yo he empezado a monitorizar dominios.

Popular ports you MUST know for ITF+ and networking basics:
80 – HTTP
443 – HTTPS
22 – SSH
53 – DNS
25 – SMTP
Save this.

Public IP → visible en Internet
Private IP → solo dentro de tu red
Ambas son clave para entender NAT 🔌

Wireshark filters every beginner should memorize:
• dns
• tcp.port == 80
• ip.addr == x.x.x.x
Small filters → big clarity.

DNS = la agenda telefónica de Internet.
Sin DNS, nada carga 🔍
Aprende a leer paquetes DNS en Wireshark → es el primer paso real hacia networking.
