Botnets, cloud computing power may be fueling attacks against VoIP

By , Network World |  Security, botnets

The increase in VoIP attacks was first noted just before Halloween last year when the peak percentage of attacks against VoIP routinely rose to a high of about 30%. In previous research, Sipera found that attacks directed against VoIP topped out at about 10%, Boone says. Since last fall the percentage of total attacks that are directed at VoIP has continued to peak at about 30%.

He offers three possible reasons for the attention VoIP is drawing. First, by and large VoIP systems are unprotected from outside attacks, he says. Second, VoIP is becoming more popular and reaching a critical mass that draws attackers. "It's common, and it gets the attention of hackers," he says. And third, there's money in it to be had easily.

Sipera has set up honeypots that are exposed to the Internet that appear to be unprotected VoIP systems. Once attackers have successfully broken in, the honeypots monitor what they try to do. They also locate the source of the attacks by country. The top three attack-launching locations are China, Russia and the U.S., followed by South Korea, Vietnam, Turkey and India, Viper Labs says.
