Symbian operating system - Nokia series 60 mobile phones - 3 new Trojans
For those of you with the Nokia Series 60 phones I have some bad news.  Symantec today has posted 3 new trojans identified that impact your operating system. 

SymbOS.Sendtool.A -  The Trojan horse drops a hacktool that can be used to send malicious programs, such as variants of the SymbOS.PBStealer family of Trojans, to other mobile devices via Bluetooth.

SymbOS.Pbstealer.D - The Trojan sends the user's contact information database, Notepad, and Calendar To Do list to other Bluetooth-enabled devices.

SymbOS.Bootton.E - A Trojan horse that restarts the mobile device when executed. However, as it also drops corrupted components, the device is unable to restart.

While looking at this information - I discovered that this particular phone OS has been hit several times in the last 2 years by trojan like programs.  I can't find anything on the Nokia site that indicates that a patch is available.  I wonder if it isn't time for Nokia to take a serious look at fixing the problem?  Especially since one of these new ones allows someone with another Bluetooth device to steal the user's information. 

What about it Nokia?  For those of you that own these devices, what are you doing to protect your phone?
