Infection
Commwarrior was particularly effective via the MMS vector it used to infect other phones. It appeared as though it had been sent from a source that was known to the victim, leading even security-conscious users to open the infected message.[3] Actually, the message was sent at random to a contact in the sender's address book. Once the message is opened, the virus attempts to install itself on the phone via a SIS file. As it runs, the worm is executed every time the phone is switched on.[1]
A secondary method of infection is to create a malicious .SIS file on a compromised phone. Once per minute thereafter, the worm attempts to send this file to any phone that has Bluetooth enabled.[4]
