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.
