From recently published report by McAfee Avert Labs:
VoIP Attacks Speak Up
VoIP attacks should increase by 50 percent in 2008. More than twice the number of VoIP-related vulnerabilities were reported in 2007 versus the previous year—several high-profile “vishing” attacks, and a criminal phreaking (or fraud) conviction—so it’s clear that VoIP threats have arrived and there’s no sign of a slowdown. Although ABI Research estimates 1.2 billion VoIP users by 2012 (with $150 billion annual service revenues), the technology is still new to many and implementing defense strategies is lagging.
which brings us to the next biggest job in VoIP technologies, security and privacy.
speaking of security, here is a graph of VoIP Vulnerabilities from the same report:
As about privacy... trust me, the global providers just don't give a .... don't care about it. If I would want to spam with voice messages, it would take one day of work to develop a system with near 100% hit rate...
Will see ;)
