Exploit
An exploit (security gap) is a computer program or script that takes advantage of a bug,
glitch or vulnerability leading to privilege escalation or denial of service on a computer
system. One form of exploitation for example is an attack from the Internet with the help of
manipulated data packages. Programs can be infiltrated in order to obtain higher access.
Fraudulent software
Also known as "scareware" or "rogueware", it is a fraudulent software that pretends that
your computer is infected by viruses or malware. This software looks deceptively similar to
professional Antivirus software but is meant to raise uncertainty or to scare the user. Its
purpose is to make the victims feel threatened of imminent (unreal) danger and to make
them pay to eliminate it. There are also cases when the victims are lead to believe they
were attacked and they are instructed to carry out an action, which in reality is the real
attack.
Hoaxes
For several years, Internet and other network users have received alerts about viruses that
are purportedly spread via email. These alerts are spread via email with the request that
they should be sent to the highest possible number of colleagues and to other users, in
order to warn everyone against the "danger".
Honeypot
A honeypot is a service (program or server) installed in a network. Its function is to monitor
a network and log attacks. This service is unknown to the legitimate user - because of this
reason he is never addressed. If an attacker examines a network for the weak points and
uses the services which are offered by a honeypot, it is logged and an alert is triggered.
Macro viruses
Macro viruses are small programs that are written in the macro language of an application
(e.g. WordBasic under WinWord 6.0) and that can normally only spread within documents
of this application. Because of this, they are also called document viruses. In order to be
active, they need that the corresponding applications are activated and that one of the
infected macros has been executed. Unlike "normal" viruses, macro viruses consequently
do not attack executable files but they do attack the documents of the corresponding host
application.
