At the heart of Apple's shocking FaceTime bug, which allowed just about anyone to turn an iPhone into a live microphone, stands a 14-year-old boy who stumbled upon the eavesdropping flaw more than a week before Apple took action.

“The thing that surprised me the most was that this glitch happened in the first place,” said Grant Thompson, a high school freshman in Tucson, Ariz. “I'm only 14 and I found it by accident, instead of the people at Apple that get paid to find glitches.”

Not only that, but Grant and his mom said they spent a week unsuccessfully trying to get Apple to do something about the bug in its FaceTime group-chatting feature. The bug allowed callers to activate another person's microphone remotely even before the person has accepted or rejected the call.

“It took nine days for us to get a response,” he said. “My mom contacted them almost every single day through email, calling, faxing.”

This eavesdropping scare is over now that Apple has disabled group chats, but the problem could dog the company. New York state officials have opened a consumer rights investigation. Others are raising questions about how long it took Apple to address the bug.

In a statement Friday, Apple thanked the Thompsons as it announced that it has identified a fix and will release it next week. FaceTime group chatting will resume then.

Grant, a straight-A student who enjoys the video game “Fortnite,” was calling friends to play the game on Jan. 19 when he discovered the flaw.

“If a 14-year-old kid discovered it, I wonder how many other people discovered it,” said Chris Wysopal, chief technology officer with the security firm Veracode.

Friday's statement said Apple's engineers worked quickly once it got the details needed to reproduce the bug. The company said it was “committed to improving the process by which we receive and escalate these reports, in order to get them to the right people as fast as possible.”
