What Is Hacking?
Hacking is the practice of exploiting weaknesses in computer systems or networks in order to gain unauthorized access and steal data or disrupt services. It can be done maliciously to cause harm or for financial gain, or it can be done in a more legitimate manner, such as penetration testing for a company’s cybersecurity. The term “hacker” gained prominence in the 1990s as teenagers breached computer systems of large corporations and government agencies to steal information or launch Distributed Denial of Service attacks. This new breed of hackers sparked media attention and the term began to carry a negative connotation.
The modern, most common use of the term hacker refers to those who have advanced technical skills and knowledge of computer systems in order to test and assess vulnerabilities for a living. This type of hacking is known as ethical hacking, and it can be used to identify and fix security issues before they are abused or exploited.
In the simplest sense, hacking is breaking apart technology to create or make combinations that the creators or originators didn’t intend, and it has a long history that predates computers themselves. The term was first used in the 1950s to describe members of MIT’s Tech Model Railroad Club, who would tinker with electrical systems and train sets to modify their functions. As the concept of hacking grew in popularity, it expanded to include using advanced computer programming and engineering to break into existing systems and push their limits.
