From your screen-shots, an attacker is using the tool called "friendly-scanner".

Enable the REGISTER/INVITE authentication immediately.

Also add the following DialPlan rule.
---------------------------------------
[Matching Patterns:]
User-Agent = friendly-scanner|sundayddr

[Deploy Patterns:]
$response = 603
----------------------------------------

Hi,
I am researching on this security issue and see that sipvicious states that the user agent is now "Asterisk PBX" instead of "friendly-scanner". When I look into my log, I see both of these names in there. Should I use the same method to block "Asterisk PBX" as well?
Also, Could you please show me how to change the admin user name?

I follow the instruction in the Section 8 Security to make this dial plan but it's not working. Could you please let me know why?

$request=^INVITE
$port=(.+)
$addr=(.+)
$registeredaddr(From)=!%1:%2

$action=403

Thank you,
taitan
