Facebook Inc. said it took down a network of accounts connected to a group of Iranian hackers who were targeting employees of defense and aerospace companies in the U.S., UK and Europe. Facebook said it removed fewer than 200 accounts operated by a group known as Tortoiseshell, which used various social media platforms to pose as recruiters, journalists and workers in other industries to gain the trust of their targets and trick them into clicking on malicious links, the company said.
