Guys over at F-Secure labs have reported a new worm in the market – the Merogo SMS worm. This virus spreads through SMS and is named Trojan:SymbOS/MerogoSMS. It works only for s60 v3 devices and is completely incompatible with any other symbian device.
It deploys itself by sending an SMS to every contact in your phonebook. The receiver will see a long message in chinese with a link in it. If you click on that link, you’ll download the infected file and it will once again start sending messages. It also sends SMS to many premium numbers.
Traditionally, no one can install an unsigned app in an S60 device. This worm happens to be a signed app which contains many unsigned apps within it. It installs them when it is being installed itself.
F-Secure is trying very hard to contain this virus as no reports of attacks outside China have been observed. But even then, beware of any Chinese messages.
