Hacker
The term hacker is derived from the English "to hack" and means something like penetrating into systems. A hacker is a person who breaks into computer/IT systems. In the 1980s, this developed into a scene. Parts of the hacker scene see their mission in pointing out and eliminating security gaps. In the public context, however, since 1983 the term "hacker" has increasingly been associated with negative and criminal activities such as the explicit exploitation of security gaps and the hijacking of data records (e.g. passwords).
