What does a Hacker do?

A hacker typically engages in activities that involve breaking into or using computer systems without authorization. This definition captures the primary aspect of hacking, which is often associated with gaining unauthorized access to systems, networks, or data. Hackers may exploit vulnerabilities in software or hardware to carry out their activities.

While some may take this knowledge and act for positive purposes, such as security research or ethical hacking, the core definition remains focused on unauthorized access. The term "hacker" can cover a wide range of behaviors, from malicious activities intended to steal data or disrupt services to those who may simply be exploring technology. However, the essence of hacking is rooted in the act of breaking in without consent.

Other options focus on roles and activities that promote security or support, which fall outside the typical definition of hacking. Those include creating secure software, improving cybersecurity practices, and technical support roles, which are not inherently linked to the unauthorized access aspect that defines hacking.
