Homonym: black hat (Villain)
"Black hat" refers to individuals who engage in unethical or illegal activities, particularly in the context of computer security. These hackers exploit vulnerabilities in systems to steal data, disrupt services, or cause harm. Their actions are often motivated by personal gain, such as financial profit or notoriety.
In contrast to white hat hackers, who work to protect systems and improve security, black hats operate outside the law. They may use various techniques, including malware and phishing, to achieve their goals. The term is commonly used in discussions about cybersecurity and ethical hacking practices.
