SAN FRANCISCO (Reuters) - Location-tracking devices that communicate with a major satellite network operated by Globalstar Inc can have their transmissions intercepted or mimicked with false data, a U.S. security researcher said on Thursday.
Globalstar, of Covington, Louisiana, has sold hundreds of thousands or millions of the devices, which are widely used for tracking valuable shipments and assets.
