It can do the same to microphones in laptops without the user knowing, the person said. Google declined to comment.The bureau typically uses hacking in cases involving organized crime, child pornography or counterterrorism, a former U.S. official said. It is loath to use these tools when investigating hackers, out of fear the suspect will discover and publicize the technique, the person said.”
