While VoIP services seem to be popping up all over the place, security groups are discovering that while they may be a cheap alternative to standard phone calls, they sure are not more secure.  Various big-name VoIP services have vulnerabilities that can allow intruders to eavesdrop, spam, spoof and launch denial of service attacks.  If you thought getting spam email was a pain to deal with, you probably don’t even want to think about how spammers can use VoIP to their advantage…

While Vonage defends itself against patent lawsuits from the likes of AT&T, the pioneering VoIP company also faces new risks from hackers.

Sipera Systems, a VoIP security company, said on Tuesday that users of VoIP services and equipment from Vonage, Globe7 and Grandstream were vulnerable to eavesdropping, spam, spoofing, and denial-of-service (DoS) attacks.

“These vulnerabilities create serious privacy and service availability issues for users,” said Krishna Kurapati, Sipera founder and CTO, in a statement. “Vonage, Globe7 and Grandstream customers can no longer assume that their VoIP providers are automatically securing their services, but they should demand best security practices be followed as a condition of becoming a customer.”[more]
