What Is Hacking?
Hacking refers to identifying and exploiting weaknesses in computer systems and networks. It is often used with malicious intent, such as stealing personal information or creating ransomware that holds digital data hostage. Hacking is both a complex and evolving profession; today’s cyberattacks involve sophisticated techniques that can go undetected by cybersecurity software and even expert IT teams.
The word “hack” has a surprisingly long history that predates computers themselves. It was first used in the 1950s at MIT to describe students who enjoyed tinkering with electrical systems and model train sets. The term then became a metaphor for breaking apart technology to create or modify features that the original creators didn’t intend.
In the digital age, hacking has become a mainstream headline story, from massive ransomware attacks that shut down businesses for days to the loss of millions of user account passwords. The consequences can be catastrophic for individuals, companies and countries. The theft of personal information can lead to identity fraud and financial loss; it can also damage a company’s reputation and result in legal repercussions.
The practice of hacking can be divided into two broad categories: ethical hacking (white hat hackers) and malicious hacking (black hat hackers). Ethical hackers use their skills for good, often to identify vulnerabilities that are then fixed by cybersecurity professionals. Black hat hackers use their skills to gain unauthorized access to computer systems and networks for monetary or other personal gains, often with the intention of damaging the targets’ reputation or causing harm. Gray hat hackers fall into the middle ground, breaching security standards but without the intentional intention of gaining money or harm.
