What is the definition of a hacker<\/strong>?<\/h2>\n\n

A hacker is a highly qualified power user who accesses servers, websites<\/a>, networks or even PCs without authorization. The data stored on them is saved, deleted or even edited. Such hackers have been around for as long as the Internet<\/a> has existed. Despite the high degree of illegality of such hacker attacks, the entire development of technology is driven by hackers. <\/p>\n\n

What exactly is a hacker?<\/strong><\/h3>\n\n

Hackers are technically highly skilled individuals in the hardware and software environment. They search for and find vulnerabilities in systems in order to draw attention to them or use them for specific purposes such as unauthorized intrusion or to change functions. The aim of a hacker is to get into systems, influence their functions, steal data<\/a> or manipulate them. <\/p>\n\n

In principle, there is no restriction on the type of devices that hackers manipulate. Hackers in the hardware environment try to change the functions by modifying devices or adding components. <\/p>\n\n

Hackers in the hardware environment<\/strong> often see their activities as a challenge and hacking is a kind of hobby to overcome the limits of the devices. In the case of IT products with programmable components, for example, the boundaries between hardware and software hackers can easily be confused. <\/p>\n\n

Hackers in the software environment<\/strong> (Internet) do not manipulate hardware, they try to gain access to systems<\/a>. Access can be gained via networks or interfaces, for example. <\/p>\n\n

Known or self-discovered vulnerabilities or programming errors are used to gain access to the systems. Once the hackers have gained access to a system, it is possible for them to access databases<\/a>, execute protected functions or influence data<\/a>. <\/p>\n\n
