Hi Nanog
I'm curious.
I have been receiving some major ssh brute-force attacks coming from random hosts in the 116.8.0.0 - 116.11.255.255 network. I have sent a complaint to the e-mail addresses obtained from a whois query on one of the IP Addresses.
My e-mail bounced back from both recipients. Once being rejected by filter and the other because the e-mail address doesn't exist. I would have thought that contact details are rather important to be up to date, or not?
Besides just blocking the IP range on my firewall, I was wondering what others would do in this case?
$ host -t txt 0.0.8.116.abuse-contacts.abusix.org 0.0.8.116.abuse-contacts.abusix.org descriptive text "18977164171@189.cn" However, I don’t see an mnt-irt: field which is mandatory for APNIC records updated/created after 2010 (unfortunately this object was last updated in 2007). So I would start by pointing to APNIC that no such entry exist and as this network is of importance for the community, the addition of an abuse/IRT POC would be beneficial for everyone and if they could help, this would be greatly appreciated. https://www.apnic.net/services/manage-resources/abuse-contacts But that’s the theory...
