Trojan Horse
Systems Affected:

SymbOS.Sendtool.A is a Trojan horse that runs on the Symbian operating system, which is the operating system used for Nokia series 60 mobile phones. 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.

The Trojan horse arrives on the compromised device as Fspreader.SIS. If the user opens this .sis file, the device Installer displays a dialog box to warn the user that the application may be coming from an untrusted source and may cause potential problems.
