Estos son casi mil atacantes diferentes (o un mismo atacante desde múltiples sources):

root@linuxito:~# wc -l /usr/local/GTFO/banned.ip     
991 /usr/local/GTFO/banned.ip

En promedio equivale a más de 200 ataques por día.

Tomemos una IP cualquiera y veamos qué hay en el log de Nginx (¿por qué fue baneada?):

root@linuxito:~# cat /var/log/nginx/error.log | grep 176.88.39.233
2017/10/25 07:03:01 [error] 27254#0: *4567009 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 176.88.39.233, server: www.linuxito.com, request: "GET /wp-login.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php7-fpm.sock:", host: "www.linuxito.com"

Jeje, típico, un robotito buscando paneles de acceso a Wordpress.

El problema es que a este nivel de ataques, el firewall se satura de reglas rápidamente:

root@linuxito:~# iptables -nL

Tener en cuenta que GTFO banea por defecto durante 92 horas, o sea casi 4 días. Esto hace que en promedio el firewall tenga 800 reglas específicas por IP (más el resto de reglas fijas). Y ante un incremento repentino en la cantidad de ataques, se pueden sobrepasar fácilmente las 1000/2000 reglas. Lo cual afectará notablemente el funcionamiento del sistema en el caso de tratarse de un servidor privado virtual (VPS/cloud) que utilice una tecnología de paravirtualización o containers (casos en los que se comparte un mismo kernel entre diferentes instancias, máquinas virtuales o contenedores).

Esto fue lo que ocurrió el día de hoy. Los navegadores daban timeout al intentar conectarse al servidor Web, aunque en una sesión SSH todo parecía bajo control (Nginx, PHP-FPM y MySQL totalmente ociosos). Al kernel (vaya a saber uno con cuántas otras instancias lo comparte) se le estaba complicando evaluar semejante cantidad de reglas en cada paquete arribado.

root@linuxito:~# service netfilter-persistent restart

De mínima tuve que bajar los tiempos de ban en la variable HOURS de GTFO:

HOURS=48

Aunque se puede hacer un análisis más profundo y tratar de determinar desde qué subredes proviene la mayoría de los ataques:

root@linuxito:~# cat /usr/local/GTFO/banned.ip | cut -d'.' -f1,2,3 | sort | uniq -c | sort -nr | head
      3 5.45.77
      2 51.36.49
      2 150.129.88
      1 99.244.32
      1 97.121.130
      1 96.127.193
      1 95.5.175
      1 95.222.28
      1 95.178.202
      1 95.160.155
root@linuxito:~# cat /usr/local/GTFO/banned.ip | cut -d'.' -f1,2 | sort | uniq -c | sort -nr | head
      4 5.45

      2 82.239
      2 78.96
      2 77.29
      2 66.181
root@linuxito:~# cat /usr/local/GTFO/banned.ip | cut -d'.' -f1 | sort | uniq -c | sort -nr | head
     20 103
     17 41
     13 190
     12 85
     12 79
     12 178
     12 175
     11 112
     10 83
     10 78

Baia baia, en el puesto #1 está China.

Sin embargo, siendo los orígenes de los ataques tan dispersos, no estoy seguro siquiera de bloquear por clases C. Siempre está el riesgo de (bloqueando por subredes) dejar usuarios legítimos fuera del sitio.

Por el momento veré cómo evoluciona el firewall con esta nueva configuración de GTFO, y espero que al menos les sirva mi experiencia.

¿Tal vez será mejor dejar de bloquear por IP? Especialmente en aquellos casos donde el atacante robot recibe apenas un triste 404...

Escucho sugerencias al respecto.
