A security hacker is someone who explores methods for breaching defences and exploiting weaknesses in a computer system or network.
Hacking is complex. Although many people associate it with crime, the same methods that hackers use to break into a system can be used to help prevent a cyber attack. This type of hacking is known as ethical hacking.Black hat hackers break into a computer network with malicious intent. They may release malware that destroys files, holds computers hostage, or steal passwords, credit card numbers, and other personal information. These are the types of hackers that everyone should look out for.
Large organisations might hire these types of hackers to make sure that their websites have fewer issues.
