What Is Hacking?
Hacking is unauthorized access and exploitation of computer systems, networks and devices for purposes other than those intended by their designers. The classic example is a cybercriminal who uses security vulnerabilities to steal personal information, like credit card or bank account numbers, from computers and devices we use for work and play. However, hackers can be found in all walks of life and do not always have malicious intent. A DIY musician who probes the circuit board of a synthesizer for “bends” to make it do more than it’s designed to is also, technically speaking, a hacker.
Early depictions of hackers in film, TV and online often portrayed precocious teens breaching major organizations’ systems for notoriety or cash. In reality, today’s hackers span a broad demographic profile, from college students and tech professionals to pre-teens and people in their 20s who are simply motivated by curiosity or greed. Many hackers use a variety of tools to gain access to systems, including phishing attacks, brute force password cracking, remote attacks on vulnerable workstations and wireless attacks using Bluetooth.
While hacking has a negative connotation, it’s important to note that ethical hackers, known as white hat hackers, carry out vital cybersecurity functions for companies and other organizations. Every industry needs skilled ethical hackers to prevent breaches.
