Why is it easier for a hacker to impersonate an actual user than break into a systemas an unknown entity?

It's easier for a hacker to impersonate an actual user because they can exploit the trust and familiarity associated with that user's credentials, often leveraging social engineering techniques or phishing attacks to gain access. Once they have the user's login information, they can bypass many security measures designed to prevent unauthorized access. Additionally, systems often have more robust defenses against unknown entities, like intrusion detection systems, making it harder for external attackers to breach without being recognized.
