Thanks, I read it in the past, I added a note about it and mentioned
that one can use sl_send_reply("200", "OK") config for a similar solution.
Cheers,
Daniel

Hello,
during the testing period of Kamailio 3.1.0, while
running it at
voipuser.org <http://voipuser.org>, I had the chance
to watch live and analyze a SIP scanning
attack. Yesterday I noticed another one by looking at
Siremis 2.0
charts, therefore I wrote an article with some hints
about what you can
use to protect your SIP services within Kamailio
configuration file.
You can read it at:

Hope is going to be useful for many of you!

Hello Daniel,
Nice read, thanks for sharing. This "friendly-scanner"
messages has really gotten out of hand lately. FYI, they
are generated by a python suite called SIPVicious (ha ha
nice pun)(http://code.google.com/p/sipvicious/) . More on
this http://blog.sipvicious.org/. The suite was developed
(really really extended the sense of the word "developed"
here - as the scripts are really basic) by a security
company who trails over Europe giving lectures on Voip
security. :)
Cheers,
Marius
SIP Vicious does have a kill command... I've tried launching
that on detection with mixed results. Triggering it from a
hash count might prove better.
The kill command (actually a bug that caused a Python exception to
be raised) was fixed in a later commit :)
Marius
With best regards,
Fred
