VoIP Hopper 0.9.9 has been released. This is the same code that was
presented at ShmooCon 4.
NEW FEATURES
* CDP Generator! VoIP Hopper can generate CDP packets in order to discover
the Voice VLAN ID, as any IP Phone based on CDP would do. In this CDP
spoof mode, VoIP Hopper will send two CDP packets in order to decipher the
VVID, then it will iterate between sleeping for 60 seconds, and sending
another packet. Not only is this faster than CDP sniffing, but it can also
help bypass any mechanisms that rely on CDP for permitting access to the
Voice VLAN.
* Voice VLAN Interface Delete: VoIP Hopper can delete the created Voice
Interface
* MAC Address Spoof, then exit: VoIP Hopper can change the MAC Address of
an interface offline and exit, without VLAN Hopping.
IMPORTANT BUG FIX
VoIP Hopper now correctly decodes 2 bytes for the Voice VLAN ID in CDP
Packets instead of only 1 byte. This corrects large VVID values (such as
415, etc) from being incorrectly decoded.
WHAT IS VOIP HOPPER
VoIP Hopper is a VLAN Hop test tool but also a tool to test VoIP
infrastructure security.
