Je vous conseille donc de faire ceci après une nouvelle installation :

iptables -A INPUT -s 175.172.174.191  -j DROP
iptables -A INPUT -s 123.132.65.176 -j DROP
iptables -A INPUT -s 103.145.13.43  -j DROP
iptables -A INPUT -s 175.21.153.128  -j DROP
iptables -A INPUT -s 178.63.34.189  -j DROP
iptables -A INPUT -s 74.120.14.36  -j DROP
iptables -A INPUT -s 34.240.212.8  -j DROP
iptables -A INPUT -s 167.248.133.52  -j DROP
iptables -A INPUT -s 162.142.125.52  -j DROP
iptables -A INPUT -s 197.53.220.102  -j DROP
iptables -A INPUT -s 134.209.87.169  -j DROP
iptables -A INPUT -s 66.151.211.226  -j DROP

bref il me faut trouver un projet qui bloque via un script toutes les IP de Chine.

Misère.

J’ai eu 64 IP différentes :
# cat /var/log/apache2/access.*.log | awk ‘{print $1}’ | sort -n | uniq -c | sort -n | wc -l
64

 

Fishing SMS via 8t0.host : ‘Le colis FR… vers … se trouve au centre de distribution. Vous pouvez suivre votre colis ici .. ‘

Quand je vois que 8t0.host est au Panama : https://who.is/whois/8t0.host c’est forcément du fishing.

En résumé : 8t0.host ( Panama ) => frtplive07985.blogspot.com => kingkongclicks.com ( Panama ) .

!!! NE PAS CLIQUER !!! C’est du fishing …

Misère.
