What is Hacking and How Does it Affect Cybersecurity?
Hacking refers to unauthorized access to computer systems, networks and digital devices with the intention to steal, change or destroy data. While it’s often associated with cybercrime, not all hackers are malicious; white-hat hackers operate within ethical boundaries and help strengthen security by conducting authorized penetration tests, while black-hat hackers exploit vulnerabilities for financial gain or other harmful purposes. Gray-hat hackers fall in between and operate with written authorisation.
When it comes to cybersecurity, understanding hacker motivations is critical for crafting defensive strategies effectively. For example, the resurgence of teenage hacker gangs highlights a trend of young individuals engaging in hacking for thrill-seeking purposes; this can jeopardize sensitive information and lead to significant breaches. By educating employees on the risks of engaging in hacking, companies can help prevent employee-driven attacks and other common threats.
The first hacks occurred long before computers were invented. In 1878, just two years after Alexander Graham Bell’s invention of the telephone, young phone operators pranked callers by changing the frequency of their calls. These individuals became known as hackers, and their tricks are now known as phreaking. Later, students at MIT began altering train sets to take advantage of technical loopholes; this is considered one of the earliest examples of hacking.
Many people store their passwords on poorly protected PCs that are susceptible to hackers, allowing them to gain access to personal information and commit cyber crimes. For example, hackers may use “code injection” to enter a website through its form fields. This allows the hacker to then record the user’s inputs, including their passwords, and use these to take over their systems.
