What is "Social Engineering"?

Hi! Today, I will talk about"Social Engineering". It is is to get the important infomations on security like password by the illegal techniques. For example, it is by taking a peek at the moments that input password and looking for scratch papers which wrote personal informations that can become keys and password by huntting for trashs from offices. In addition, today, there is a technique that pump the new password by pretending to be a user of network and customer, asking the manager change of password by making a call. If you try the social engineering and was arrested because of knowing the information from reading this blog, I do not feel well. Therefore, finally, I say again that social engineering is illegal.
