Aliases :

There are no other names known for Trojan:SymbOS/Singlejump.A.

Explanation :

A trojan that secretly downloads malicious files from a remote server, then installs and executes the files.

Additional DetailsTrojan:SymbOS/Singlejump.A affects devices running the Symbian S60 operating system. It is distributed in a malicious SIS file named 'PhotoID.v3.06_NEW_7610_3230_6630_SMPDA.sis'.
On execution, the trojan installs small component into locations where it replaces system and third party applications; if these applications are launched, the component resets the device.

Singlejump.A also installs a modified Bluetooth-Worm:SymbOS/Cabir variant that it uses to spread Trojan:SymbOS/Bootton.A to nearby Bluetooth-accessible devices; the modified Cabir is not started automatically but will start when device boots.


Execution
On execution, Singlejump.A replaces built in and third party applications with component that causes device to reboot when executed.

It also uses a Cabir variant that is modified so that instead of sending a copy of itself, the worm loads a specified SIS file (which is installed by Singlejump.A to a location where Cabir expects to find its own file) and starts sending it. In this case, the specified file is a copy of Trojan:SymbOS/Bootton.A.

The modified Cabir worm that Singlejump.A uses is based on Cabir.B and maintains the same replication flaw; thus, it is only capable of sending SymbOS/Bootton.A to the first phone it finds after reboot.
