CommWarrior : What does this virus do?

This virus will reset your phone on the first hour of the 14th of every month. It spreads using Bluetooth and MMS utilising your phonebook contacts to send the MMS to.

SymbOS/CommWarrior is the first known mobile malware that spreads via both Bluetooth and Multimedia Messaging Service (MMS). It can also be downloaded from malicious web sites as an archive file named COMMWARRIOR.ZIP.

It affects phones running the Symbian S60 platform. Some phones affected by SymbOS/CommWarrior include the following:

Bluetooth Propagation

Once running in a device, SymbOS/CommWarrior searches for other phones with Bluetooth. Once a target phone is found, it sends a randomly named SIS file to the target.

The SIS file enters the target phone’s Inbox attached to a message. When the message is opened, it activates the SIS file and installs the following:

!:systemappsCommWarriorcommwarrior.exe
!:systemappsCommWarriorcommrec.mdl
