Hello,
during the testing period of Kamailio 3.1.0, while running it at
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
