static.cmcti.vn tried to do some security funny business and was testing my security. I was curious so did research.
static.cmcti.vn is anything but static. In fact there is a lot of research on this host name. It seems this guy has been very active and has changed IPs on a very regular basis.
As Viet Nam is an emerging country I’m unsure about banning large swaths of IP ranges.
Observation:
static.cmcti.vn 183.91.3.182 comment spammed me and I now have a positive IP to ban.
