"The mobile devices you know and love are great for productivity, but they have completely changed the vulnerability state of our networks. Norm Laudermilch tells you why you should be afraid, very afraid." From the article: "The new and largely unexplored propagation vector for malicious code distribution is mobile devices. With 802.11, Bluetooth, WiFI, WiMAX, MMS, Infrared, and cellular data capabilities on almost all new models, these devices provide a wealth of opportunity for the transmission of data. With no notion of user access levels in the compact mobile operating systems, a lack of effective authentication, and no data encryption, these environments are prime targets for the incubation of malicious code."
