Three new malicious Trojans aimed at mobile phones
running the Symbian operating system have been released into the
wild.
The Trojans, malicious programs disguised as legitimate
applications, are spread via the Bluetooth short-range wireless
technology or through multimedia messages.
Their appearance has been reported by anti-virus software
companies Symantec and F-Secure, which say that infection rates are
so far low.
The Bootton.E Trojan is the potentially the worst of the three
as it can restart the mobile device and leave corrupted components
that render it unusable.
The Pbstealer.D Trojan can send out the infected user’s contact
list, notepad and calendar to-do list to other nearby users via
Bluetooth. And the Sendtool.A Trojan sends malicious programs to
other devices, also via Bluetooth.
Unlike many worms on PCs that can spread quickly without users
knowing, these Trojan horses aimed at mobile devices spread as
attachments that require users to download them, meaning the
infection rate is not expected to be great.
