I could be wrong, but I think the story was contained here [0], where a chilean programmer was targeted through a LinkedIn face account set by north korean hackers.
There was also "Operation Socialist" [1] where the UK's GCHQ with the aid of the NSA hacked Belgacom, via phishing linkedin emails. Darknet Diaries also had an episode on it.
