Reuters reported that Yahoo secretly built custom software to search through their users' incoming emails for a particular set of characters for the FBI and NSA. "It is deeply disappointing that Yahoo declined to challenge this sweeping surveillance order, because customers are counting on technology companies to stand up to novel spying demands in court," he said in a statement. It was unclear which intelligence agency directed Yahoo to scan emails, the person familiar with the matter said. The challenge was heard in the secretive Foreign Intelligence Surveillance Court and some details about the case have remained under seal. Instead of looping in the security team, Mayer turned to the Yahoo’s email engineers to develop the software, Reuters reported.
