What Is Hacking?
Hacking is a term used to describe the process of using technical knowledge, problem-solving skills, creativity and persistence to bypass security measures and gain access to private information or protected systems. It’s most commonly done maliciously to steal data, breach systems or devices, create worms, and spread viruses. However, it can also be conducted ethically to improve security, which is called “white hat” hacking.
There are four key drivers that lead people to hack websites or systems: financial gain through stealing credit card details, defrauding financial services, corporate espionage (for hire), and state-sponsored hacking to spy on adversaries or disrupt their critical infrastructure. Other motivations include extortion, in which hackers hold data, systems or devices hostage until victims pay ransom, and political activism, as is the case with hacktivists such as Anonymous and WikiLeaks.
Once bad actors have a foothold in the system, they’ll often install backdoors and rootkits to maintain persistent access and evade detection. Additionally, they may delete logs or use obscuring tactics to hide their activity, helping them remain undetected for longer periods of time.
While hacking is often depicted as fast and easy on TV shows and films, it takes a lot of work, dedication and skill to learn the necessary techniques. For that reason, aspiring hackers should approach learning this skill with realistic expectations. The process of gaining the required skill set will take many months and in some cases years. Moreover, the constantly changing digital landscape means that new hardware, applications and vulnerabilities are emerging all the time. This is why it’s essential for any hacker to continuously evolve their skills and stay on top of their game.
