A stalker is on the loose — and may be watching and listening in your bedroom, bathroom or office meeting.

Just ask Tim Kuykendall, whose cell phone provided a portal through which a hacker gained access to the most intimate details of his life, recording family members' conversations and snapping pictures of what they were wearing.

“We’ve had [times] where I’m having a conversation in my home and I get a voice mail and the conversation’s replayed; received a phone call or even checked my voice mail from a message and while I push 'OK' to listen to [it] I’m hearing a conversation going on in the living room between my daughter and my wife,” he told FOX News.

That's not all. One message left on his phone follows: "I can’t wait till you die. Oh, my gosh. You will all be dead, even the officers.”

“Obviously, it’s frightening for the family,” he said.

Kuykendall, who is working with police, said when he reported the activity to his provider, Sprint, he was not taken seriously.

"They said it wasn’t possible; it’s not happening. We’ve had bills that have piled up because they’ve downloaded some ringtones," he said of the phone activity, which has been happening for months.

And switching phones and other steps have not put an end to the privacy invasion.

“They know our every move and they like to let us know that,” said Tim Kuykendall's wife, Heather Kuykendall.

“We started off by changing phones, changing phone numbers,” she said.

Heather Kuykendall said the family turned to the media after the police wouldn't believe their story, and said the FBI now is investigating the claims after the chilling messages left on voice mail.

Security expert Paul Miller said it is not uncommon to receive such reports.

“The phone will be used to capture the pictures and the sounds around it and then they’re shipped out over the air to some sort of Web site where the people can look at it,” said Miller, a cell phone security expert with Symantec.

“We’ve seen the applications become viruses that affect people’s phones and do allow you to invade a person’s life,” he said. “A lot of people forget that the mobile device on your hip is a computer these days and it’s always with you; it’s always a risk."
