Programs used for
flooding networks
They send a great number of messages via
network channels. These channels include,
for example, programs used for flooding
internet relay chats.
However, this type of malware does not
include programs flooding e-mail traffic and
IM and SMS channels. Such programs are
classified as individual types described in
the table below (Email-Flooder, IM-Flooder
and SMS-Flooder).
Hacking tools are used to hack computer
on which they are installed or to arrange
attacks on another computer (for example,
to add other system users without
permission; clear the system logs in order
to conceal any traces of they presence in
the system). They include some sniffers
which perform malicious functions, for
example, intercept passwords. Sniffers are
programs which allow viewing network
traffic.
These programs scare the user with virus-
like messages: they can "detect" a virus in
a clean file or display a message about
disk formatting which will not take place.
These programs send messages and
network request with a fake sender's
address. Intruders use spoofers in order,
for example, to pretend to be a sender.
They are tools
used to create
modifications of
malware programs
They make it possible to modify other
malware programs in order to hide them
from anti-virus applications.
