Skype can become a control tool

Internet telephony services such as Skype and Vonage may inadvertently help cybercriminals send spam and denial of service (DDoS) attacks to knock down websites.

Furthermore, security experts at the Communications Research Network, a partnership between Cambridge University and MIT, said VoIP software uses proprietary technology and data is encrypted. so it cannot be intervened by a third party. " Although this security method has many positive effects, it can also be a solid cover that allows attackers to exploit the leak without detection ", Jon Crowcroft, Professor at Cambridge University, the prize prefer.

Communications Research Network recommends that Internet phone providers should publish routing standards or switch to open standards. " This measure will help other legal organizations quickly detect bad criminals in VoIP systems ," Crowcroft said.

Currently, such attacks are usually done through zombie computers. They combine into a network (botnet) and are remotely controlled. VoIP applications such as Skype (currently on eBay) can give criminals a new tool to control these zombie systems. Skype and Vonage have not provided answers to these comments.
