Sense: noun/1
While hacking broadly refers to any unauthorized access to computer systems, cracking specifically means breaking security measures with malicious intent — all crackers are hackers, but not all hackers are crackers. Intrusion focuses on the act of entering a system without permission and is commonly used in formal security reports ('intrusion detection system'). Cyberattack is a broader term covering any digital assault, including viruses, denial-of-service attacks, and data theft, of which hacking is just one method. Break-in is an informal, everyday word that can refer to computers or physical premises. For example: 'The attack started with a simple break-in using stolen passwords, but the full cyberattack involved weeks of careful hacking and data theft before anyone noticed the intrusion.'

Etymology
The word 'hacking' is the gerund form of the verb 'hack.' The verb has two separate origins that later converged. One comes from Old English 'haccian' meaning 'to cut or chop roughly' — from this root come both the 'hacking cough' (a cough that sounds like rough cutting) and the computer sense (which began at MIT in the 1960s, where 'hack' meant a clever, creative technical solution; by the 1980s it had shifted toward unauthorized access). The horse-riding sense comes from a different origin: 'hackney,' a Middle English word for a horse available for hire, which was shortened to 'hack' by the 1600s and later gave rise to 'hacking' for recreational riding.
