VoIP Hopper, A VoIP Security Testing Tool

VoIP Hopper http://snapvoip.blogspot.com/

VoIP Hopper is intended for network engineers, VoIP administrators, and professional security testers to assess the security of networks they have permission to test / assess. Even though VoIP Hopper is a VoIP infrastructure security testing tool, it could effectively be used to test the security status of VLANs as well.

The tool is GPLv3 licensed  and is written in C. One needs a Linux based system, a C compiler and good old libpcap to make and run. The tool is designed to run a VLAN Hop into the Voice VLAN on targeted Ethernet switches. VoIP Hopper mimics an IP Phone, in Cisco, Avaya, Nortel, and Alcatel-Lucent environments.  IP Phone emulation requires discovery of the correct 12 bit Voice VLAN ID (VVID) used by the IP Phones and is accomplished via multiple protocol discovery methods (CDP, DHCP, LLDP-MED, 802.1q ARP). Once the initial stem is accomplished, VoIP Hopper creates a virtual VoIP Ethernet interface on the OS.  It then inserts a spoofed 4-byte 802.1q vlan header containing the 12 bit VVID into a spoofed DHCP request.  Once it receives an IP address in the VoIP VLAN subnet, all subsequent Ethernet frames are "tagged" with the spoofed 802.1q header.

There are many uses of the tool for a VoIP engineer or professional and needs to invest some time learning the tool. VoIP Hopper site provides a swath of information, including code download, instructions and video tutorials (Of on which is embedded below). Happy ethical hacking.

Ultra High Speed 100G Switched Ethernet Services Field Trial Complete : Verizon

Ultra Speed, 100G Ethernet Field Trial http://snapvoip.blogspot.com/
Verizon has completed the industry leading ultra high speed Switched Ethernet Services (Verizon SES) field tests. 100 gigabit-per-second Ethernet traffic on a metropolitan Ethernet infrastructure were tested using Alcatel-Lucent equipment deployed in Verizon's Switched Ethernet Services network.The trial successfully transmitted data over 12.7 kilometers (7.9 miles) of field fiber in the company's Dallas area network.

"With this 100G Ethernet trial, Verizon is preparing for the future and the need to meet our customers' bandwidth needs in the metro Ethernet space, the 'network of tomorrow' will include building blocks such as 100G Ethernet that allow us to scale our switched Ethernet core as access speeds and customer demands increase. Our goal is to show 100GE can be carried on a metro network and do it with current equipment that avoids major changes -- and the associated costs -- to the existing network infrastructure" said Jean McManus, executive director of technology for Verizon.

The trial, which ran from June 14 - 18, used existing Alcatel-Lucent 7450 switching equipment with new plug-in cards to place native 100GE traffic on a single fiber, creating the high-speed links. Alcatel-Lucent's 7450 ESS nodes used 100 GE service interfaces with 100GBASE-LR10 optics, which provide low-cost, high-bandwidth transport over distances of up to 10 kilometers (6.2 miles).

"A seamless transition to 100GE leveraging existing Alcatel-Lucent IP Routing platforms enables Verizon to expand its innovative Ethernet service offerings in a timely and efficient manner, Services are the driver of revenues and the rationale for investment in the network. Our platforms deliver speed without compromising services, leveraging our breakthrough 100G silicon innovation and long-standing relationships with leading service providers such as Verizon." said Robert Vrij, president of the Americas region at Alcatel-Lucent.
