Document Viruses

Document or “macro” viruses take advantage of macros – commands that are embedded in fi les and run automatically.

Many applications, such as word processing and spreadsheet programs, use macros.
A macro virus is a macro program that can copy itself and spread from one file to
another. If you open a file that contains a macro virus, the virus copies itself into the
application’s startup files. The computer is now infected.

When you next open a file using the same application, the virus infects that file. If your
computer is on a network, the infection can spread rapidly: when you send an infected
file to someone else, they can become infected too. A malicious macro can also make
changes to your documents or settings.

Macro viruses infect files used in most offices and some can infect several file types,
such as Word and Excel files. They can also spread to any platform on which their host
application runs.

Macro viruses first appeared in the mid-1990s and rapidly became the most serious
virus threat of that time. Few viruses of this type are seen now

Denial of Service attack (DoS)

A denial-of-service (DoS) attack prevents users from accessing a computer or website.

In a DoS attack, a hacker attempts to overload or shut down a computer, so that
legitimate users can no longer access it. Typical DoS attacks target web servers
and aim to make websites unavailable. No data is stolen or compromised, but the
interruption to the service can be costly for a company.

The most common type of DoS attack involves sending more traffic to a computer than
it can handle. Rudimentary methods include sending outsized data packets or sending
email attachments with names that are longer than permitted by the mail programs.[sintuhack]

An attack can also exploit the way that a “session” of communications is established
when a user first contacts the computer. If the hacker sends many requests for a
connection rapidly and then fails to respond to the reply, the bogus requests are left in
a buffer for a while. Genuine users’ requests cannot be processed, so that they can’t
contact the computer.[sintuhack]

Another method is to send an “IP ping” message (message requiring a response from
other computers) that appears to come from the victim’s computer. The message goes
out to a large number of computers, which all try to respond. The victim is flooded with
replies and the computer can no longer handle genuine traffic.[sintuhack]

A distributed denial-of-service (DDoS) attack uses numerous computers to launch the attack. Typically, hackers use a virus or Trojan to open a “back door” on other people’s
computers and take control of them. These “zombie” computers can be used to launch
a coordinated denial-of-service attack.[sintuhack]

Browser Hijackers

Browser hijackers change the default home and search pages in your
internet browser.

Some websites run a script that changes the settings in your browser without your
permission. This hijacker can add shortcuts to your “Favorites” folder or, more seriously,
can change the page that is first displayed when you open the browser.

You may find that you cannot change your browser’s start page back to your chosen
site. Some hijackers edit the Windows registry so that the hijacked settings are restored
every time you restart your computer. Others remove options from the browser’s tools
menu, so that you can’t reset the start page.

In every case, the intention is the same: to force you to visit a website. This inflates
the number of “hits” and the site’s ranking with search engines, which boosts the
advertising revenue that the site can earn.

Browser hijackers can be very tenacious. Some can be removed automatically by
security software. Others may need to be removed manually. In some cases, it is easier
to restore the computer to an earlier state or reinstall the operating system.Browser hijackers change the default home and search pages in your
