HIGHPanda Virus Alert - Zafi.D Most Detected
Panda Software Reports Zafi.D is the Most Frequently Detected Virus By
Users of Activescan.
Orange Alert Remains as Virus Spreads Rapidly Across the Globe.
Three New Worms: Atak.H, Atak.I And Atak.J Appear Bearing Xmas Messages
- TruPrevent Technologies, the most intelligent technologies to combat
unknown viruses and intruders, have effectively blocked and eliminated
Zafi.D, without needing to be able to identify it first
Glendale, CA December 15, 2004 - According to data collected via Panda
Software’s free online antivirus tool ActiveScan, the Zafi.D worm, which
appeared just yesterday, is already the most frequently detected virus
around the globe, mainly in South America and Europe, where the most
affected countries are Italy, Spain, Bulgaria and Hungary.
This worm spreads in a file attached to email messages containing the text
Happy holidays! As we are in the run up to Christmas, users are sending
millions of greetings via email, which is helping Zafi.D to spread widely
and rapidly.
To prevent this worm from continuing to spread, especially through
computers that do not have adequate anti-malware protection installed,
Panda Software has released its free PQREMOVE utility, which detects and
eliminates Zafi.D from all the computers it may have infected. This tool
can be downloaded from: http://www.pandasoftware.com/download/utilities.
Zafi.D is a multi-lingual worm, as it can adapt the language of the message
to the domain of the email address it is being sent to, for example, a
German-speaking user will receive the message in German. This significantly
increases the capacity of this worm to spread.
“Zafi.D is a typical example of a worm that takes advantage of important
dates to spread as widely as possible. This has happened in the past, and
therefore, we were not surprised when it emerged. However, Zafi.D uses
social engineering effectively, above all in adapting the message to the
recipient’s language, who will not be surprised to receive Christmas
greetings from companies, family and friends which include an animation,”
explains Luis Corrons, head of PandaLabs.
What’s more, Zafi.D can be used to gain control of affected computers, as
it opens a backdoor in affected computers through a communications port.
This allows an attacker to connect to the port and gain remote control of
the affected computer.
Three new worms with Christmas messages that try to trick users have also
just appeared. The three worms are: Atak.H, Atak.I and Atak.J and reach
users in an email with the following characteristics:
- Subject: "Merry X-Mas!" and "Happy New Year!".
- Message text: "Happy New Year and wish you good luck on next year!",
"Mery Chrismas & Happy New Year! 2005 will be the beginning!"
- Zip file attachment called: pif, com, scr or bat.
Atak.H, Atak.I and Atak.J also copy themselves to the Windows System file
with the name DEC25.exe.
Given that we are in the Christmas season, many users may open these files
thinking that they are festive greetings. The appearance of these three
variants coincides with the massive spread of Zafi.D which is now the
malicious code that is most frequently detected by Panda ActiveScan.
Due to the high possibility of being, Panda Software advises users to take
precautions with any email messages they receive and to update their
antivirus software. Panda Software has made the corresponding updates
available to its clients to detect and disinfect this new malicious code.
Panda Software clients who already have the new TruPrevent Technologies
installed have been protected since the worm first emerged, as these
preventive technologies have been able to detect and block Zafi.D without
needing to be able to identify it first (more information about the new
TruPrevent Technologies at
