Curiosity is one of the most common
things that we have since childhood. Exploration is also part of curiosity. It
has positive and negative effect if we have curiosity in relation to the modern
world. But let’s focus on the negative effects of exploration. Through
internet, exploration is to navigate, to search and to open. We must be careful
on what to open if we are accessing internet. That’s where computer viruses occur.
If we are curious, we explore. If we explore, we open. And if we open especially
if that thing feels unprotected, we are prone to computer viruses. Types of
computer viruses that basically I know are Trojan and worm. These are the common
ability of computer viruses. Like Anna
Kournikova. First, let’s look back from the past life of Anna on why she
became a threat to the net.
Being known as one of the spice girls
of tennis, Anna Kournikova was very popular not only in the field of tennis but
also popular in culture like in poker term hole card Ace-King(Looks great but
never wins) and a very well known virus Anna Kournikova that arose on February
2001. It was very popular virus on that year because it has been found in several
Microsoft Outlook e-mail users and infected several enterprise companies.
By spreading messages through e-mails,
users are tricked to open the message with the subject of”Here you have, ;0)”,
with the message body containing the statement “Hi: Check this!” And an attachment of a photo appearing with
the well known sexy tennis player, Anna Kournikova. The attachment appears as
AnnaKournikova.jpg.vbs or an abbreviated version of her name. It appears to be
a false image but actually it is a visual basic script. The virus uses visual
basic to infect the systems of Microsoft Outlook that mails itself and propagates
throughout the entire address book of the infected user. Just like launching a thousand ships! It is similar to I love you
virus and was classified as worm because it spread through e-mails and also
considered as a Trojan because of the attachment that hid the script of visual
basic as a photo.
Provided by the information from FBI
team, police stated that "The young man had downloaded a program on
Sunday, Feb. 11 from the Internet and later the same day, around 3:00 p.m., set
the virus loose in a newsgroup.”. Because of the major impact generated by the
virus, it can overload and crash e-mail servers. It has been found throughout
Europe and North America and is expected to surface in Asia as well. They found
out that the man behind this was a Dutch programmer Jan de Wit after he turned himself in the authority two days after
the virus propagates. "I didn't do
it for fun," he stated on the posting dated Feb. 13. "I never wanted to harm the people
who opened the attachment. But after all: It's their own fault they got
infected."
The behavior of this virus is to
create following changes in Windows registry that should be deleted.
HKEY_USERS\.DEFAULT\Software\OnTheFly
HKEY_USERS\.DEFAULT\Software\OnTheFly\mailed=(1 for yes)
It also
leaves a file AnnaKournikova.jpg.vbs in the c:/windows directory. Other than
deleting the files and the registry entries, the virus must be deleted by an
up-to-date antivirus or a virus checking program.
