Social engineering techniques involve different tools and different types of attacks in which they try to retrieve the secret and confidential information of the victim. These attacks can be personal or online. Personal attacks are those in which the attacker physically tries to obtain information. For example by impersonating a particular person and through conversation subtly asking questions whose answers can reveal secrets, or by eavesdropping on a conversation in a public place. Cyber attacks are attacks where the victim is tricked into taking risky actions, such as logging into fake websites, clicking on a contest or free content, and so on. In social engineering, an attempt is made to deceive a person so that they would reveal secret information and thereby enable the execution of an attack. Phishing is one such attack, and the practical part of the work demonstrates a phishing attack by sending a link to a fake page and waiting until the victim enters user data. As soon as the victim entered the data and pressed "Enter", access to the victim’s data was obtained and the attack was successfully completed. This information can be used to access the victim's Internet profile (e.g., Facebook profile), find out a lot of personal information, or use this access to send a phishing attack to the next victim.
