Firewall off Winbox and/or upgrade. Run 6.40.8+ for bugfix or 6.42.1+ for current.

Someone from the outside world logged into winbox today. I had what I 'thought' were strong passwords on them. The only active service on the router is the Winbox Service. The only changes that were made was they enabled the 'socks' server, and added input firewall rule for the socks port. They were in and out of the router in a matter of seconds, so it looks like it was scripted somehow. I'm going through now and changing passwords and verifying all routers are locked from the outside. On the routers that I've found this on, all the logins were sourced from this same IP Address. So far the affected routers I've found were running versions 6.39-6.41.3 Might be a good time to check your logs and access controls. jul/15 02:29:14 system,info,account user admin logged in from 194.40.240.254 via winbox jul/15 02:29:17 system,info,account user admin logged in from 194.40.240.254 via telnet jul/15 02:29:18 system,info socks config changed by admin jul/15 02:29:18 system,info filter rule added by admin jul/15 02:29:19 system,info,account user admin logged out from 194.40.240.254 via winbox jul/15 02:29:19 system,info,account user admin logged out from 194.40.240.254 via telnet -- AF mailing list [email protected]<mailto:[email protected]> http://af.afmug.com/mailman/listinfo/af_af.afmug.com
