In the course of the ever-increasing spread of broadband Internet connections, a new danger is increasingly emerging in addition to the threats in the area of IT use that have existed for a long time and are known in many cases: that one's own IT system is unknowingly misused as part of a botnet. By violating basic security rules, there is a risk of becoming part of such a botnet.

What is a »Bot«?

»Bot« is derived from robot and refers to a computer program that largely independently executes certain tasks that are often repeated. Bots pose a security problem when they infect other computers in the form of Trojans in order to execute certain commands remotely, as unnoticed by the user as possible.

What are »bot networks« oder »botnets«?

»Bot networks« oder »botnets« are a remotely controllable association of a large number of computers infected with bots, which are often abused for spam preparation and DDoS attacks.
Further information on the topic can be found on the website of the Federal Office for Information Security (BSI), among others.
