BTW for those wondering quite easy to block entire IP block allocations of a company. 1) get the offending IP and find the AS number e.g https://www.whois.com/whois/151.123.178.0 2) Every host has what's called an ASN Autonomous System Number It's their block of IPs grouped together, it's how the larger internet routes them to the correct host. BTW they can have more than one ASN. Theirs is AS200373 3) Look up their IP blocks here: https://hackertarget.com/as-ip-lookup/ they are in CIDR format, even in spreadsheet format 4) Plug into your firewall of choice. 5) I have an alias script for IPTables callled droprange, but you can just do what I did, paste the list into a text editor, prefix every line with 'ufw insert 1 deny from'. I find Sublime Editor great as you can edit every line at once. iptables more tricky, I think it can use CIDR? I forget. Use UFW if you can, it's not in the dark ages! But same idea. Then pasted it into the terminal window. Yes I could script it but tooks hours last time. #asn #hackers #ddos #blocking
