Some more details on Cabir, the mobile phone virus that is appearing in the wild. Apparently, the virus was firstly spotted in a cell-phone in a Santa Monica, and has proved to be very effective at infecting nearby smart phones: a combination of handheld computers and cell phones were effected. The virus can indeed spread by Blue tooth wireless data transfer.
Apparently the work of the group 29A Labs, the goal of the virus's makers seems to be to create new, unique and interesting viruses. They have certainly done that. Although this development is not completely catastrophic, it does demonstrate clearly that smart phones and other similar devices will be targeted by viruses from now on.
