Hacking 101 – What is Hacking?
The term hacking was first used by members of MIT’s Tech Model Railroad Club who would modify their high-tech trains to do new things. Later it evolved to mean tinkering with computer code to find shortcuts and improve efficiency. Today, the most common usage is gaining unauthorized access to computer systems. This is often illegal, but there are ways to do it legally for a living, known as ethical hacking.
Ethical hackers are cybersecurity professionals that help organizations prevent system breaches. They assess a company’s security measures, identify vulnerabilities and take the necessary precautionary steps to protect against malicious cybercriminals. They’re in high demand, and you can train to become one in less than a year.
A successful hack typically starts with a phishing attack. These messages can appear as an email, text or even a phone call asking the victim to log on and provide sensitive information. If the victim clicks on the link, the hacker has gained unauthorized access to their system.
Then they can start to steal or manipulate data, disrupt services or cause financial losses. Black-hat hackers exploit security vulnerabilities for financial gain or political motives and are a serious threat to businesses and governments. Grey-hat hackers operate in the gray area between ethical hacking and committing cybercrimes, identifying vulnerabilities but not exploiting them for illicit purposes. Finally, state-sponsored hacking is a growing concern, potentially compromising national security and destabilizing economies. These activities can also erode public trust in government institutions.
