More trojan programs showing up for the Symbian smartphones

Posted on 3-Dec-2004 22:09 | Filed under: News


In addition to the previously know Cabir, Skulls and a Skulls variant that incorporated Cabir, it is now known of a new threat industry experts are calling Cantimer.

Simworks, the company behind the development of an anti-virus for the Symbian platform with 127963 UIQ and 127965 Series 60) says that the Camtimer.b is carried inside a file called camtimer.sis, which is a combination of the legitimate Nokia Camtimer application for Series 60 and Cabir.b.

Camtimer.b is a standalone version of Camtimer.a, which was packaged inside Skulls.b. Both the Camtimer.a and Camtimer.b trojans have been packaged with Cabir.b. The first incarnation of this trojan was broken and incorrectly installed Cabir.b such that it did not auto-start. It seems that Camtimer.b corrects this error.

The Cabir trojan was the first step into the real world of security threats on this platform. The program has the capability to auto-initialise itself when the smartphone starts and then use the Bluetooth wireless connection to send copies of itself to nearby Bluetooth devices.

Unlike Skulls, Camtimer.b is not an immediate threat to mobile users and Simworks say it has not yet been reported in the wild.
