Over the last year, U.S. officials, concerned about how many names have shown up on such terrorist lists, have warned military personnel to guard their social media profiles.
"While these individuals never demonstrated an extremely high level of technical sophistication that we typically associate with state-sponsored actors in China or Russia, they were able to successfully use crude but effective data mining techniques to gather outwardly relatively innocuous information that, when put into the wrong hands, could be quite harmful," said Evan Kohlmann, a terrorism analyst for NBC News.
