Security Experts at MicroWorld
Technologies inform that 'Trojan.Win32.Dialer.ay' is a porn dialer Trojan
which works in a clandestine way to run reckless charges on telephone bills of
unsuspecting Internet users.
'Dialer.ay' stops the existing Dial-up connection
and connects to a highly expensive pornographic number like the '900' series in
US or even numbers of a foreign country. Victim's telephone bill will run into
exorbitant levels and in many cases, users are forced to pay at least a percentage
of the charges to get rid of the mess. If you really want to get these undue charges
completely off your back, it will cost a lot of run around, complaints and even
legal action, wasting your time and money again!
"Sometimes it's noticed
that dialers act in a calculated and controlled manner where they charge a certain
'not so big' sum every month. Users will be caught completely unawares of this
drain, which might go unabated for months on end and at times, years. Even when
you detect this theft finally, it becomes hard to get the whole amount reversed!"
says Sulabh Mahant, Security Analyst, MicroWorld
Technologies.
If you have a broadband connection and you do not use
the Dial-up modem any more, it's advised to remove the modem and telephone connection
to avoid falling prey to this potential risk. With the arrival of broadband, the
number of Dial-up connections has dropped drastically. Subsequently, dialer Trojans
are now migrating to smart mobile phones. The 'mosquito' Trojan found last year,
infects a game by the same name played on Symbian Operating System on Smart phones.
This Trojan sends hundreds of messages to some specific numbers.
"There
are two major ways a 'Dialer Trojan' can infect computers," observes Govind
Rammurthy, CEO, MicroWorld Technologies. "One
is through injecting an ActiveX control to the PC via browser while user accesses
the Internet. Then this component goes ahead and downloads the dialer from a predefined
website. Two, the Trojan comes bundled with a plethora of freewares available
on the net. Even some of the small free utilities like schedulers and calculators
you find on the web are found to be carrying Dialer.ay."
When you
have a malware bundled into a masqueraded utility, oftentimes the malicious code
is rewritten and altered to make it almost unrecognizable for many AntiVirus solutions
who merely depend on Virus signatures. At MicroWorld Technologies, this challenge
is overcome by combining an intelligent behavioral analysis of suspicious objects,
with the traditional signature method. MicroWorld's AntiVirus and Content Security
Solutions eScan and
MailScan employ
this strategy to provide a total, seamless threat protection for users.
