I read a very interesting article about how to prevent infection from H1N1 as it relates to your cellphone worms. We already know that H1N1 is for humans but we don’t know that there is a swine flu like in our cellphones. Interesting… The name of this swine flu like disease has many name variation as the security vendors give different names. Like for example, Symantec named this as SymbOS.Exy.A and F-Secure called this as SymbOS/Yxe. No need to worry as they are all the same. Then what this worm does?

This worm attempts to send SMS messages or connect to the Internet and may yield:
Abnormally high phone bills
Rapid battery power loss

Presence of the following files :
c:\sys\bin\EConServer.exe
c:\private\101f875a\import\[2001EB45].rsc

Impossible to launch the following applications:
AppMgr
TaskSpy
Y-Tasks
ActiveFile
TaskMan

Which version of Symbian OS are affected by this? This worm targets mobile devices running Symbian OS 9.1 S60 3rd Edition like Nokia 3250, Nokia N73. Also it affects wide range of devices on Symbian OS 9.2 S60 3rd Edition FP1 version.

How to prevent from this infection? Don’t install any applications that you suspect malicious coming through Bluetooth, etc.
