The Voice over Internet Protocol (VoIP) products of Avaya, Cisco and Nortel are filled with more than 100 vulnerabilities, according to a report from VoIPshield Laboratories. Polish researchers have developed a range of steganographic techniques which would enable a hacker to hide information in VoIP traffic. VoIPshield Laboratories has alerted companies that market voice over IP systems of new security vulnerabilities. The W/32 Skipi.A worm that nagged Skype users in early September was fairly routine by malware standards. It arrived pretending to be a message from another user, offered erotic pictures, infected machines via malicious links, stole information and moved on to other PCs. Organisations are overlooking the security risks, planning considerations and business needs in the rush to capitalise on VoIP, argues ISPhone’s James Spenceley. Cisco late Wednesday patched seven severe vulnerabilities in its widely used internet telephony software that could permit device compromise or system shutdown. As the epidemic of spam and malware continues to barrage email systems, one might think the industry would have learned to build strong security into new communications protocols. Unfortunately, in the case of VoIP - the most important new communications protocol since SMTP - this is not true. Historically, the development of VoIP infrastructure has prioritised quality and reliability over security, with few security measures being built in. Voice over (IP) is a dream concept for companies and organisations all over the world. With voice calls being sent over the internet, money can be saved on long-distance calls and intra-office calls. Voice over Internet Protocol (VoIP) phone systems relying on so-called "soft phone" software are open to thousands of potential vulnerabilities, researchers at Sipera Systems' said at the annual Black Hat conference last week in Las Vegas. VoIP provider stays tight lipped about cause of outage. Attacks targeted towards voice communication channels such as VoIP and mobile phones are quietly increasing, security researchers have warned.

Cisco has patched its Unified CallManager and Presence Server software to fix vulnerabilities that could allow DoS attacks. Cisco sewed up two serious vulnerabilities in its widely deployed IP telephony software that could allow attackers to initiate a system shutdown or takeover. CompTIA study reveals wariness of IP telephony security. The hacking community is outpacing the security industry, and different sectors of the IT community need to work together more closely to narrow the gap. WatchGuard Technologies is launching a network security appliance that targets enterprise campuses, data centres and other high-performance network environments. Unified Communications Manager contains multiple vulnerabilities which could lead to a denial of service attack against an organisation's VoIP network, Cisco has admitted Data will continue to be the primary motive for future cybercrime, according to a 2009 forecast from researchers at Georgia Tech. VoIP cuts costs and streamlines communication for enterprises, but are the benefits worth the security risks? Dan Kaplan investigates. Traffic analysis can help warn of terrorist attacks, but it can also be used to crack encryption, so we need to act now.
