Internet & Email - Happy hunting ground for Viruses
Internet has opened up the information exchange flood gates.
Openness provides the opportunity to the bad boys to implement
their designs. Internet can be utilized in following manner:
- Designing scripts for virus activation and for
writing viruses. These scripts can be activated
even if you just visit the page. They can also be sent as attachment.
- Trojans can be sent. They send the server component,
which gets installed on the user machine. Now with
the help of another component called the client component
it is possible to remote control the machine through
the Internet thread.
- Through attachment with E-mails. They can be disguised
under fancy names and tempt the user to immediately
click on the attachment. Once clicked ......
- Through worms which uses mail to spread itself
automatically. Happy99, Melisa etc are classical
examples of such worms.
- Virus utilizing the holes of Email client (till now
only Outlook Express) and spreading through that.
