Mobile Malware: The Brief History

A new more dangerous time for mobile device users, filled with mobile malware, is upon us. As with desktop computers, the Lilliputian world of PDAs and smartphones is no longer immune to malicious attack.
This new reality was emphasized this week by the discovery of the one of the most sophisticated mobile viruses yet produced, Lasco.A. Unlike previous malware, Lasco.A attacks most often when users attempt to trade programs, but will also try to infect phones that are connected to its host device within Bluetooth range.
It all began "innocent" enough with a pair of "proof-of-concept" trojans, but quickly got ugly—when virus writers with less "benign" intentions jumped on the mobile malware bandwagon.
In this article, we take you through the trojans and viruses that were designed to affect and infect handhelds and smartphones over the last half a year or so, before directing you to articles on how to keep their PDAs, cell phones, and smartphones safe.
The list is in reverse order, moving backwards from Lasco.A.
