Is the default password social engineering?

Question

Information Security

Good afternoon, I have this question: The
rather famous Mirai botnet uses the fact that people leave the standard login / password on their devices.
Is Mirai related to social engineering hacking? Or are standard passwords not social engineering?
If not, what is it called? (Brute?! :).. Does Brute relate to Social Engineering? )
After all, in fact, the person himself decides to leave the standard password "And so it will do", no?
He can put his own, but he is not vigilant enough and the attacker takes advantage of this.

Answer 1

did you read the definition?
1) Social engineering is a method of obtaining the necessary access to information based on the characteristics of people's psychology. The main goal of social engineering is to gain access to confidential information, passwords, banking data and other secure systems.
2) Social engineering is a method of controlling human actions without the use of technical means. The method is based on exploiting the weaknesses of the human factor and is considered very destructive.
where is in your "Standard password" and "Brute" - the impact on human psychology?

Answer 2

In most standards, this comes as a separate item "default passwords"
