-====== Squid - Alerts - ET SCAN Sipvicious User-Agent Detected (friendly-scanner) ======
-This is a scanner that looks for SIP servers.
-SIP Servers are part of your VOIP infrastructure
-----
-Technically speaking though, SIPvicous is a SIP auditing tool used to scan for and enumerate SIP devices and accounts.
-It can be obtained freely from it’s Google Code archive, the GIT repo or bundled with security auditing tools like Kali.
-Originally intended for legitimate white hat security auditing for internal networks, in the hands of even the most bored of script kiddies it can cause some serious damage.
-That lazy network admin using common username/password combos will yet again fall victim to this one.
-SIPvicous will send INVITE or OPTION packets looking for responses from live hosts, then log the results to a file.
-An attacker can then begin to enumerate for valid usernames and passwords which if successful, can get access.
-In addition, these Invites commonly cause what I call “ghost calls” (phones ring from random callers but no one’s home).  Worse still, they can even initiate un-wanted calls.

-===== How Does it Work? =====
-**SIPVicious** is made up of 4 components – The head, the front legs, the hind legs, and the torso. I’m kidding of course…there’s actually 5..
-**Svcrack** – Used to crack SIP passwords for a given username. Brute force or dict-based.
-**Svreport** – Store session info for later use, ie; Cracking a password or reading packets elsewhere.
-**Svmap** – “The annoying one” that does the scanning for open SIP targets – usually with an INVITE or OPTIONS request.
-**Svwar** – Scans for and enumerates phones on the network.
-It probes for phones by sending packets out and listens for a response, same as above but it seems there’s more manipulation that can be done in terms of what the packets are and what size. This could potentially be used as a DDoS tool.

-**Svcrash** – Defend and Counter-attack tool against ..itself.
-This tool can be setup to read the asterisk log and automatically obtain a would be attackers IP and Port, attempting to shut down his agent with a malformed response packet (more on that later). Manual entries can also be set and optional Brute force on the destination port – woot woot!
