How does one hack a Vonage account?

I can only think of three ways:  Standard SSL MITM attacks (requires shared 
media), Keystroke capturing spyware, attacks against Vonage account 
server.  Number 2 is the most vunerable, it would seem.  And the attacker 
would typically be after things other than disabling emergency communications?

There's no limit to what can be accomplished if it doesn't matter who gets 
the credit
