Cyberattack is any wrongful activity performed with an aim to alter the functioning or gain unauthorized information from computer networks, computer information systems or personal computer devices. To try and gain unauthorized entry into a computer system, a cyber-attack hacker can try either of the following procedures; denial of services(DOS), malware, phishing, session hijacking, structured query language, and cross-site scripting

In phishing attacks the attackers send you an email which has some warning in it, for example, “someone tried to log into your email address. Click the link below to protect your email address from an unknown log in.” Upon clicking the link, the user ends up installing a malware into their computer. Phishing attacks are focused on the user’s emotions and personal desires which are likely to influence them to click on the sent link.

Attacks aimed at fetching a company’s data, company’s intellectual property and personal credential are some of the reasons why whaling attacks focus on high profile targets. Changes are made to a legitimate message by sending false URLs and attachments to a user and upon opening it, a malware is installed. By getting details such as a company’s email address and website, the company’s logo, an attacker is able to craft an email that looks real to the specific target who happens to be the high profile workers in a company and once clicked a malware is installed therefore altering the normal function of a computer.
