Should we be afraid yet? A group of researchers said they found the first virus that can jump from a PC to a mobile device, exactly the scenario that invokes visions of massive chaos. The malicious code, named "Crossover", was sent anonymously to the Mobile Antivirus Researchers Association as a proof of concept bug. Meanwhile, Russian anti-virus specialist Kaspersky Lab has discovered evidence of the first mobile phone Trojan targeting J2ME devices, an unexpected move in light of the fact that most security experts were thinking that Symbian was going to be the primary target. The sample Trojan, "Redbrowser.A" is a J2ME-based Java Midlet that disguises itself as a WAP browser that offers free browsing. But the Trojan sends text messages to premium rate numbers.
