An anonymous reader writes "The New York Times is reporting that a team of researchers led by Matt Blaze has discovered that technology used for decades by law enforcement agents to wiretap telephones has a security flaw that allows the person being wiretapped to stop the recorder remotely. It is also possible to falsify the numbers dialed. The flaws are detailed in a paper being published by the IEEE. Someone who thinks he's being wiretapped can apparently just send a low tone down the line that turns off the recorder. The link has a demo."
