When the Food and Drug Administration started spying on a group of agency scientists, it installed monitoring software on their laptop computers to capture their communications.
The software, sold by SpectorSoft of Vero Beach, Fla., could do more than vacuum up the scientists' e-mails as they complained to lawmakers and others about medical devices they thought were dangerous. It could be programmed to intercept a tweet or Facebook post. It could snap screen shots of their computers. It could even track an employee's keystrokes, retrieve files from hard drives or search for keywords.
