Did you read the article? You don't ask for passwords saved in the weights. Its 'socially-engineering' an LLM.
Yes I did and my comment is spot on. People share credit cards with LLM's and agents. A socially engineered LLM can be tricked into buying crap just I constantly tricked the snitch-bot into buying crap. People are using shared agents to access LLM's from .ai websites. It's going to get even dumber than all of this.
