I use the following code on all my production OpenSIPS servers.
It's CPU friendly and avoids being spotted by bots searching for open-relay
VoIP servers.

route{
     # put it at the very beginning of route section
     if($ua=~"friendly-scanner") {
        xlog("L_ERROR", "Auth error for $fU@$fd from $si method $rm
user-agent (friendly-scanner)\n");
        drop();
        exit;
     }
(...)

Since I added that code problem with friendly scanner is over.
