Novi virusi na Symbian-u   
Ove nedjelje pojavio se virus koji napada uredjaje sa Symbian operativnim sistemom serije 60. Inficiranim telefonima normalne ikone zamijenjene su ikonama lobanja i kostiju, a sam uredjaj ne moze se resetovati.

Prvi put ovaj trojanac Skulls Trojan nadjen je u programu Extended Theme Manager kojeg je razvio Tee-222.

Problem je prakticki nerješiv osim ako na uredjaju nije instaliran još neki program za baratanje datotekama. Ni Symbian ni druge antivirusne kompanije još nisu komentarisale ovaj napad.

"The skulls software apparently infects only the Nokia 7610 phone. Other phones from Nokia, Motorola or Sony Ericsson are reportedly unaffected. While the Symbian statement says it's possible that other phones using the company's Series 60 OS could be affected, it apparently has not happened yet. "

A pazi ovo covece :

"The Cabir worm found in Skulls.b was packaged with an application called Camtimer, a piece of free Nokia software. The Camtimer/Cabir.b worm combo (Camtimer.a) packaged with Skulls.b was not pack correctly and the Cabir virus would not auto-start.

This new variant, Camtimer.b has been packaged correctly and so in this version Cabir will auto-start.

The installation file for Camtimer.b is called CAMTIMER.sis."
