There’s very little detail in the article. I’d be curious to find out exactly what the intern’s responsibilities were, because based on the description in the article it seems like this was a failure of management, not the intern. Interns should never have direct access to production systems. In fact, in most parts of the world (though probably not China, I don’t know) interns are there to learn. They’re not supposed to do work that would otherwise be assigned to a paid employee, because that would make them an employee not an intern. Interns can shadow the paid employee to learn from them on the job, but interns are really not supposed to have any actual responsibilities beyond gaining experience for when they go on the job market.

Blaming the intern seems like a serious shift of responsibility. The fact that the intern was able to do this at all is the fault of management for not supervising their intern.
