A virus has been found that can move from mobile phones to computers, although experts say that it is neither very dangerous nor very sophisticated. CARDTRP.A or Sybos/Cardtrap.A runs on the mobile phone OS Symbian, and tries infect a PC if the phone's memory card is plugged into it.

"The only thing new that it does is ineffectively try to spread to the PC from the phone -- this is new behavior for phone malware but old hat for traditional malware. The IIS/sadmind worm, for example, spread to both Solaris and IIS," Ed Moyle, president, SecurityCurve, told TechNewsWorld. "So, it's not really new or innovative in itself -- it does, however, apply old concepts in a new way."
