Viruses

A computer virus, believed to be the first spread by mobile phones, has
recently been sent to anti-virus firms. No infections have been reported,
and this virus is harmless, but it is proof that mobile phones could be
at risk from virus writers. The virus, known as Cabir, infects phones and
devices running the Symbian operating system and can be passed to
other devices via Bluetooth. Requiring Bluetooth to travel significantly
restricts the threat posed by the worm as it is thereby constrained to
a radius of about 30 metres. Also, transfer is dependent upon a nearby
phone user having Bluetooth turned on and accepting the virus in spite
of it being preceded by a warning that the source of the file is unknown.
For now, the Windows operating system is still the primary target for
virus writers and they do not seem very interested in mobile devices.
Indeed, the first virus for a Palm device was detected in 2000 and
it has not, to date, resulted in a problem for PDA owners.
