Re: [AFMUG] mikrotik hacked.....again

Exactly what Lewis said. We take an "allow specific things, block everything else" approach. We only allow a small list of IP addresses to access Winbox or SSH on a router. And aside from a small list of other services the router needs to respond on (rate-limited ICMP, established/related, DHCP on some interfaces, OSPF or LDP on some interfaces, BGP from IP ranges of internal routers), everything else in the INPUT chain is explicitly dropped.

If you want in, you have to VPN there first.  On Sun, Aug 5, 2018, 1:12 PM CBB - Jay Fuller <par...@cyberbroadband.net> wrote:   Looking through all of our routers, most running the latest firmware, most running non-standard winbox ports, i still see the following today:   * accept rule in firewall  (for port 10438 i think, same port enabled on ip -> socks) * account added called "service" * socks config changed ; enabled * log entries changed to only show one line   anyone else seeing this?  What are they doing?     -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
