black hat
Black hat hackers have a criminal approach. They penetrate a computer system or network without authorization and intentionally cause damage to data and programs.
The goal of black hat hackers is to find vulnerabilities in the security structure of computer systems in order to steal, destroy, or falsify data and files, or to steal records to offer to other criminal organizations. Black-hat hackers boast about breaking the law by telling other hackers or spreading it through social networks.
Black-hat hackers are criminal. They are the opposite of white-hat hackers, who pursue ethical goals and are hired by companies for vulnerability analysis.
