VOIP makes networks vulnerable

It was demonstrated at ShmooCon, how a laptop connected to a VOIP telephone could expose a business' internal network to outsiders, says CNET News.

John Kindervag, senior security architect for Vigilar, said that public waiting areas in hospitals, conference rooms and hotel rooms are particularly vulnerable to this attack.

Appearing on stage at the East Coast computer hacker conference with Kindervag was Jason Ostrom, manager of Vigilar's Vulnerability Assessment and Compliance Practice team. He showed off his latest version of VOIP Hopper, a tool that allows one to hook up a laptop computer to a public VOIP phone and connect to the company's or organisation's internal network with full administrator access.

Digifonica International has announced the release of its consumer VOIP over WiFi service under the brand "JustCallMe", reports Trading Markets.

Embedded within a Nokia device, the IP telecommunications solutions provided by Digifonica will allow customers to place VOIP calls directly from their phones.

Customers can place and receive telephone calls from every major fixed, VOIP, mobile and wireless carrier in the world via local WiFi access points.

Cisco rushed out a brace of security to defend against potentially dangerous exploits via its VOIP kit, including the possibility of malicious code being injected into vulnerable networks, reports Channel Register.

The twin advisories from the network giant cover a range of vulnerabilities in Cisco IP Phones and its Unified Communications Manager call management software.

A range of Cisco 7900 Series IP Phones are subject to multiple flaws, some of which may lend themselves to attacks involving the execution of arbitrary code on a vulnerable phone.
