weak passwords (user error) not really hacking

If you need to cross a chasm, and someone rolls a boulder in that lets you get across, are you going to go into all the ways that it wasn’t really a bridge?

Hacking is about making stuff do things outside is intended purpose. There are no prescriptions on how; hacking doesn’t gatekeep. If it works, it’s a hack. Convincing sometime to open the door for you is social engineering, for example.

So, if someone uses/reuses weak passwords, it’s fair to say that’s an easy hack, but it’s still a hack.
