Yet it’s not only carriers that could be concerned with the type of attack Pena and Moore launched, says Seshu Madhavapeddy, CEO of VoIP security company Sipera Systems.
Madhavapeddy says these types of attacks are relatively easy to carry out and could hit at enterprises just as easily as carriers.
Infonetics Research predicts spending on VoIP will jump from $1.2 billion in 2004 to more than $23 billion in 2009.
Emerging technologies like unified communications that include voice, video, and data in one console, intended to drive collaboration through the roof, have the potential to put more and more information at the fingertips of hackers. They warn about phishing not unlike what companies and consumers see in e-mails.
And VoIP networks are just as susceptible to crippling denial-of-service attacks as are data networks, and mass calls generated by a worm could overload networks or kill productivity with ceaseless phone calls and messages.
