A new report from the Information Security Forum (ISF) warns that along with existing security problems associated with IP networks, VoIP will present new and more sophisticated threats – such as caller ID spoofing, voice modifiers, SPIT (voicemail SPAM) and packet injections. With VoIP now poised to hit the business market in a big way, the ISF believes that failure to address these serious risks may bring voice communications to a grinding halt and result in identify theft and loss of sensitive information. With a combination of caller ID spoofing and freely available voice modification software, it is relatively easy to pose convincingly as someone else — similar to web site spoofing and phishing.
