The computer virus is the oldest malware. As early as 1974, the first computer virus, “Rabbit,” was developed. Viruses are programs that can replicate themselves in order to spread from computer to computer in this way. Then steal or delete data on the affected systems. Most viruses are hidden in a program. As soon as the user runs this program, the virus spreads. The user spreads viruses by unintentionally forwarding the infected files, e.g., by email or on data carriers such as USB sticks.

2) Worms

Worms are similar to computer viruses, but they do not depend on the “assistance” of the user and spread independently via networks and data carriers by mercilessly exploiting security gaps.

3) Trojans

Botnets are a whole group of PCs that have been infected with malware and combined to form a large network. These botnets often extend over several thousand computers. The malware used is called robot programs (bots). They are remotely controlled by hackers and used for criminal offenses. For example, they automatically send massive amounts of spam and spy out data. All of this happens in the background without the user being able to suspect that his computer has become part of a criminal structure. In addition to computers, mobile devices such as smartphones or tablets can also be affected by bots.

10) Denial of service attacks

Constant availability of servers, applications, and data is essential for companies. It is precisely this high commodity that the hackers target in a Denial-of-Service (DoS) attack. They try to attack websites and servers to make important data or entire systems inaccessible to the owner. This is usually achieved through targeted attacks on servers to overload them completely. To this end, huge numbers of requests are directed to the server.
