The worm spreads by sending text messages that contain variable messages in Chinese and a link to a website at 188.8.131.52. If the link is followed, an application will be installed promptly.
The malware will be registered to start on the phone boot up, and tries to connect to a website at http://rec[...]rzwxdsu.com over GPRS or 3G connection, infecting the phone and restarting the SMS spreading.
The worm has also been spread on different Chinese file sharing web sites in a file disguised as a game or theme for Symbian Series60 3rd & 5th edition phones.
