-----Original Message----- From: information_technology-admin@private [mailto:information_technology-admin@private] On Behalf Of InfraGard Sent: Tuesday, December 30, 2003 8:38 AM To: information_technology@private Subject: [Information_technology] Daily News 12.30.03 December 29, CNET News.com - Communication breakdown threatens VoIP. Currently, about 11 percent of all phone calls use nationwide voice over Internet Protocol (VoIP) services at some point in the connection. Most of this VoIP shuttling takes place in delivering international calls, through IP network providers. Calls are handed off to traditional circuit-switched networks at either end, but make long-distance jumps using cheaper packet switching, or IP, technology. As more calls shift to IP, these handoffs will grow in volume and complexity, raising significant technical issues for carriers, experts said. The basic protocols used to signal VoIP connections, session initiation protocol and H.232 are evolving standards that have been implemented differently by equipment makers. As a result softswitches and Internet protocol gateways from one vendor may not interoperate with equipment from another. And if the equipment sitting on each network isn't able to talk to each other, then the call can't be completed. A new category of product has been developed to help alleviate this issue. VoIP session controllers can be deployed between two carrier networks to help simplify the protocol conversion. But even with session control technology translating the protocols, carriers still need to test and tweak the networks at the interconnection points.

A new virus is spreading by e-mail in Malaysia, combining threats of terrorist plans and a Trojan horse virus. Victims receive an e-mail that claims to warn of five planned terrorist attacks, with the times and places leaked by an anonymous Malaysian government source. The e-mail's subject line is "Urgent message to all citizens of Malaysia," and the e-mail says it seeks to minimize the number of terrorist victims by spreading the terrorist attacks information, reported the Star, a Malaysian daily. Inside the e-mail is an embedded link that purports to link to a site with important information regarding the attacks. However, the Malaysian Computer Emergency Response Team (myCERT) said that clicking on the link instead installs three malicious files that appear to be Trojan horse virus files and adds a new key to the computer registery. Then the virus attempts to connect to three Internet hosts set by the virus. MyCERT said that the three Internet hosts to which the virus attempts to connect could have had their security compromised already. They have notified the three hosts' system administrators.
