Security Experts at MicroWorld
Technologies inform that “Trojan-Dropper.Win32.Agent.alv”
is a new addition to the Trojan Dropper family, known
to drop various Trojans and Viruses into user computers
while working in the system background.
This kind of malware is employed to install Trojans,
greyware other malware on the user computer without
the knowledge of the user or even sometimes by misleading
the victim.
According to MicroWorld Experts, the modus operandi
is that it will display an error message or warning,
mostly from the system tray at the bottom right hand
side corner of the computer. Now a message that gets
displayed on that part of the screen is taken rather
seriously by users, as many important programs and
utilities are stationed there.
Once you click on the message, a new malware is installed
to a specified location on the local disk, which gets
launched immediately. Now each of these new files
may contain invitations for more malware to keep this
chain growing in number and dimension.
“These are different from the upgradable worms
that we’ve seen in the case of Sober series.
In there, it was just one specific type of worm improving
its own code with small incremental files. Instead,
a Trojan Dropper deposits all kinds of malware once
it gains an entry into the computer. From Spyware
to Trojans to Rootkits they don’t spare any breed!”
observes Govind Rammurthy, CEO, MicroWorld
Technologies. So far “Win32.Agent.alv”
seems to be found only in North America, but chances
of it spreading wider cannot be ruled out, he points
out.
Another important aspect of a Trojan Dropper is its
distraction methods and smart techniques employed
to mislead the victim. Most of them carry hoaxes,
jokes, games, graphics and so forth to make the user
think that they are harmless while discreetly performing
deadly operations in the background.
“Hackers are getting Trojan Droppers to slip
through many AntiViruses which does not analyze all
components of a downloaded file. This breed further
underlines the need for deeper analysis of each data
component that finds its way to your computer. Because
a rather harmless looking code can turn out to be
the mother all evils!” says Govind Rammurthy.
