Hackers are individuals who gain access to someone’s system and take absolute controls of it remotely without the user’s knowledge. They are able to do this by using spywares that are launched into the user’s system after running an adware contain the malicious program or installing a program such as file sharing programs e.g. Kazaa or e-mail attachments. When the user runs these files, they install the spywares without knowing in their systems, in return the spywares open a back door i.e. port 8080 and is the gateway that the hacker uses to gain access into your system. Damages that can be inflicted in the system by the hacker include IP spoofing.
