It looks like at least a few (i didnt check all of your ips) routers are still running 6.40.9 which is vulnerable to winbox exploitation to harvest credentials and gain admin-acces on the router afterwards. To be honest: Its your fault that your routers are running that old, vulnerable software. If you additionally opened the Winbox port (or didnt firewall it properly) the attackers were able to read your credentials and login via telnet (which was not firewalled as well as it seems).

There is one chance. Check if you are able to use this exploit if mac-winbox under /tool mac-server mac-winbox is enabled and reachable from local ports: ...

Grab the credentials, unplug the router from the net, login and clean it off. And always upgrade your routers, it cannot be said often enough!
