Step-by-step explanation:
A person who gains unauthorized access to networks in order to steal and corrupt information and data is called a hacker. Hackers use various methods to infiltrate systems, which can involve creating sophisticated software to break into networks, devising phishing schemes to trick individuals into clicking malicious links, and manipulating users to disclose sensitive personal information. As our online activities increase, we expose more of our personal lives on the internet, thus heightening our risk of falling victim to such cybercrimes. According to a report by the Pew Research Center, concerns about online privacy have escalated significantly, with incidents of online harassment and theft of personal information, such as Social Security numbers, also being reported.
