you know, this time the virus under the name Sobig.F has wreaked quite havoc!
No doubt, many of us have suffered from this recent virus outbreak.
According to an online poll conducted by CNN – 32% of respondents were infected
with this malicious virus. At the pick, each of every 17 emails contained sobig.F!
Internet service provider AOL says it scanned 40.5 million emails and found
the virus in more than half of them. Sobig accounted for 98 percent of all viruses
found in these emails.
What is Sobig.F virus?
This is a worm type of virus. Which means it is an executable program that
installs enhancement to your Windows operating system. The ‘F” implies that
it is the sixth of the family of Sobig viruses. The first one was launched in
the beginning of this year. The latest attack was started on August 19.
According to some experts, Sobig.F was first posted to a porn Usenet group
and spread from there. It is timed to deactivate itself on September 10. The
pre-built deactivation mechanism itself is a worrisome factor. Most experts
think this means there are more to come!
How it works?
Sobig.F comes along with an e-mail with subject headers like Your details,
Thank you!, Re: Thank you!, Re: Details, Re: Re: My details, Re: Approved, Re:
Your application, Re: Wicked screensaver or Re: That movie. The body of the
message is quite short and usually contains either "See the attached file
for details" or "Please see the attached file for details."
Once the file is opened, Sobig.F resends itself using a built-in mailing program
to e-mail addresses from the infected computer. As a sender’s address it shows
one of the e-mails randomly selected from the computer's address book.
The worm was also supposed to attempt to retrieve an URL from a predetermined
list of 20 master servers on a certain date and time. The content of that URL
was to be downloaded and executed on the infected machines. Luckily those servers
were identified right away and shut down.
