F-Secure Weblog: August 27, 2005 -- We've now seen the first medium-scale internal infection of a company that was caused by a mobile virus. On Wednesday this week, we were working on a case where a single company had a serious run-in with the Commwarrior.B virus. Several dozens of employees of the company received Bluetooth or MMS transmission of the virus during the day-long outbreak and over twenty of them actually opened the message on their phones and got infected with it.
Viruses are new to mobile phone technology and they are beginning to circulate more extensively in-the-wild. To date most infections have been with single individuals. F-Secure briefly documents how a company's address book is most likely used to spread the Commwarrior virus to dozens of individuals in a company. At least 20 true infections resulted that required cleaning and removal of the mobile phone virus.
