Text files are perceived to be rather safe and harmless
to download from the Internet or emails and open in
one's computer without much fear about Virus infection.
But not for the users of Japanese text editor program
Ichitaro, which saves files with '.JTD' extensions.
Security experts at MicroWorld Technologies inform
infected JTD files are smartly employed in exploiting
a recently found vulnerability in Ichitaro, in order
to spread a covert backdoor named 'Win32.Papi.a',
thus orchestrating targeted computer attacks in the
land of rising sun. Justsystems, the makers of Ichitaro,
has issued a patch for the flaw, downloadable at http://www.justsystem.co.jp/info/pd6002.html

The backdoor penetration is carried out using a malicious
JTD file that backpacks a Trojan Dropper named 'Ichitaro.Tarodrop.a'.
The Trojan Dropper exploits a Unicode Stack Overflow
Vulnerability in the text editing software to execute
its code on the system and to extract a backdoor named
'Win32.Papi.a'.
Once activated, Win32.Papi.a installs itself in the
system registry, initiates a Service named CAPAPI,
drops its main DLL file which is then injected into
the running processes of the compromised computer.
It establishes a connection with the remote Server
on port 8080 and listens for commands from the remote
attacker.
The backdoor can harvest system information, stop
and start processes, take screenshots of the desktop
and send them to the attacker, download files from
the net and execute them, capture network user information,
log off current user, search disks for files, create
and move directories and restart the victim's machine.
Using Win32.Papi the attacker takes over the targeted
machine completely to conduct a range of online criminal
activities.
"It's not the first time text editors are used
in smuggling malware into user computers. In May,
we had reported about 'Win32.Gusi' that was spread
via a specially created Word file that exploited a
security flaw in Microsoft Word, which incidentally
was reported the first time in Japan with the attacker
possibly sitting in China," says Sunil Kripalani,
Vice President, Global Sales and Marketing, MicroWorld
Technologies.
MicroWorld has developed the World's most advanced
Security Solutions, eScan and MailScan, that consistently
maintain the fastest malware detection and prevention
rate. Combining the superior AntiVirus System with
its unique MWL technology, MicroWorld protects users
from a range of zero-day threats of this nature.
The CEO of MicroWorld Technologies, Govind Rammurthy,
gives a broader view on the issue "Trojans and
Backdoors that exploit vulnerabilities in system and
application software can spread quiet fast and deliver
their payload without much of user intervention. They
are like camouflaged infiltrators who sneak into your
homeland and expand their deadly mission under the
cover of darkness. And this particular case goes well
to underline what we have been advocating all along,
that users need to update timely security patches
not just for their Operating Systems, but for application
software programs as well."
