Cisco Confirms VoIP Security Hole

Tony Bradley Tony Bradley Profile: Tony Bradley

VoIP is the new wireless (unfortunately, wireless is still the new wireless as well). By that, I mean it is the hot new technology that everyone is implementing even though they don’t really know how to properly deploy it and they have even less knowledge of how to secure it. Vendors are guilty too. They rush products to market to take advantage of the popularity, but the products are not designed securely and they are not adequately tested. The result is a bunch of flawed and vulnerable VoIP networks out there, built on essentially beta-version hardware, just waiting to be exploited. At HACK.LU 2007 in Luxembourg this past October, security researcher Joffrey Czarny described a technique to eavesdrop on remote conversations using Cisco VoIP phones. Check out Cisco confirms ability to spy on remote calls with VoIP to learn more about this, and other, VoIP exploits that may affect your cutting edge phone network.
