Cyber crimes involve the use of the internet to commit crime. The most typical of these are discussed as follows.
Fraud involves the illegal acquisition of account details of an individual with the aim of manipulating it for ones gains. Fraudsters acquire passwords to fiscal services of users and may use them to access money and other financial services. They may also hack internet sites and obtain information pertaining the clients’ accounts. Criminals also tamper with data systems so as to gain free services.
Impersonation in social media sites is a cyber crime that involves the cyber criminal hacking into a user’s account. They then post trivial information about the user or even use it to reach close friends of the user with malicious intent. Another manifestation is where they may tag people in awkward posts which often lead to shame and destruction of the victim’s self esteem.
Phishing is another offence where a criminal sends links to users mainly via e-mails normally called spam. These links are full of viruses that are harmful to computers. Through the links criminals may also be able to get data about the user. Spam mails are unpleasant to users.
Hijacking is the process where a third party absorbs a connection between two parties without the consent of the parties. One technique used is where a website is set up with almost the same name as a website most users love. Users may find themselves in such website either by entering slight spelling mistakes or typos. Another method is where the attacker comes up with his own page. He then redirects users to this page as a way of showing them the site has been jeopardised.
