První reálné viry v mobilních telefonech05.10.2004
The Cabir worm has started to infect mobile phone users in Singapore in what is thought to be the first outbreak of a mobile phone virus in the 'wild'. A proof-of-concept version of Cabir was written by virus writing group 29A in June 2004 and distributed to anti-virus firms. Now, the worm, which affects phones using the Symbian operating system and spreads through Bluetooth, has appeared in the wild. Cabir currently does not pose a major threat. The worm only spreads through mobile phones that have Bluetooth connectivity switched on, and the main effect at present is that it drains battery power as it seeks to spread. New variants of the worm could be more damaging, however.
