The only good news is that the danger level of these Trojans is still low.

Since the beginning of January, Symantec has identified nine new Trojan programs targeting Symbian operating systems installed on mobile phones.These "vandals" take down the phone, find ways to install other malicious software into the system or steal data stored in the computer, secretly sending it to a predetermined device.

On the market today, Symbian is still the most popular operating system for smartphones.Nokia, the world's number one mobile phone maker, has also opted for Symbian for its high-end products.Two-thirds of smartphones shipped in the third quarter of last year were operating on Symbian, according to research firm Gartner.

In the face of the growing threat of mobile phones, Nokia signed a contract with Symantec last October, whereby all of its Series 60 smartphone models are equipped with anti-software software. Symantec Mobile Security virus.In addition, two other big names, F-Secure and McAfee, have also started to trade in security products for mobile phones.

According to Symantec, all 9 newly discovered Trojans are spread via Bluetooth, wireless shortwave technology that most smartphones are equipped with.In particular, Cdropper has 5 variants, two versions of Pbstealer, two "Sendtool" Trojans and "Booton".

While Pbstealer seeks to send address books, notepad content, work schedules and business memos to other Bluetooth devices, the Cdropper attempts to install versions of Cabir worm and Locknut into electricity. phone.

However, the most dangerous and destructive must mention Booton, the Trojan has just been discovered last week.When successful, it will cause the phone to reboot, but the boot process fails, as Booton has released several "destructive" files into the system.

Even so, Symantec reassured customers not to panic.Although the number of attacks has increased, the real risk remains low.Most Trojan programs require users to open a file received via Bluetooth, after reading a warning from the system that the file is sent from an untrusted source.

Not so optimistic, many security experts still predict mobile phone viruses will inevitably become an increasing headache this year.
