Blackhat hacker is a digital bandit with serious computer skills, looking to crack security for personal gain. These cyber outlaws often specialize in things like malware creation, spam delivery, exploit hunting, and DDoS attacks. But not all of ’em use their own digital weapons; some just sell the know-how to top bidders. Their loot of choice? Financial info (credit card digits, bank accounts), personal deets (emails, passwords), and juicy company data (employee/client databases). Beware of these digital desperados!
