What is a Hacker?

A hacker is someone who uses technical expertise to solve computing challenges. The term may refer to any skilled programmer – including “ethical hackers” – but in common contemporary usage, it typically signifies a cybercriminal.


Hacking usually describes attempts to compromise digital systems, including computers, smartphones and even critical infrastructure. Hackers are inspired by several motivations, including financial gain, political/social goals (hacktivism), state or corporate espionage or simply amusement.
