You can refuse to call them hackers, everyone is entitled to be wrong about something.

Kevin Mitnick was a prolific hacker who used social engineering regularly to infiltrate, and hackers still do today. Humans are a massive weak point in any org, that's why we have to take quarterly training not to be a moron and let someone into our network through doing something stupid.

Hacking is making something work in an unconventional or unexpected way. Social engineers hack people in that way.

Defcon would disagree. I've watched so many presenters talk about all forms of penetration testing, many of which used social engineering and lockpicking as a way to create exploitable vulnerabilities in networks. Whether or not you care to call them hackers... It doesn't really matter, won't stop them from hacking.

Real hackers social-engineered their way into high security systems decades before the first blue haired femboy nerd proudly announced "Btw i am usin Arch!"
