Chapter 4 FortiOS Carrier : MMS Security features : Why scan MMS messages for viruses and malware? : Example: COMMWARRIOR
  
Example: COMMWARRIOR
This is a virus for Series 60 type cell phones, such as Nokia, operating Symbian OS version 6 [or higher]. The object of the virus is to spread to other phones using Bluetooth and MMS as transport avenues. The targets are selected from the contact list of the infected phone and also sought via Bluetooth searching for other Bluetooth-enabled devices (phones, printers, gaming devices etc.) in the proximity of the infected phone.
This virus is more than a proof of concept - it has proven successfully its ability to migrate from a zoo collection to being in-the-wild. Currently, this virus is being reported in over 18 different countries around Europe, Asia and North America.
When the virus first infects a cell phone, a prompt is displayed asking the recipient if they want to install “Caribe”. Symptoms of an infected phone may include rapid battery power loss due to constant efforts by the virus to spread to other phones via a Bluetooth seek-and-connect outreach.
The following variants among others are currently scanned by the FortiOS Carrier devices, in addition to more signatures that cover all known threats.
