Analysis: Wireless phone headsets insecure
WASHINGTON, Feb. 1 (UPI) — Wireless phone headsets of the kind beloved by Wall Street executives and high-end law firms can be bugged by simple off-the-shelf radio scanners unless they are encrypted.”These guys are bugging their own office, essentially,” security consultant Doug Shields told United Press International.
He said that, for a recent client, he had used an inexpensive commercial scanner capable of monitoring frequencies in the 900 MHz and 1.2 GHz ranges, which is where many of the popular hands-free headsets operate.
He said the scanner could hear conversations inside buildings as far as 600 feet away. “Sometimes, when the other party has hung up, the wireless connection remains open and you can hear what (the party at your end) is saying afterwards.”
