Black Hat 2015: Hacker shows how to alter messages on satellite network

Globalstar satellite transmissions used for tracking truck fleets and wilderness hikers can be hacked to alter messages being sent with possibly dire consequences for pilots, shipping lines, war correspondents and businesses that use the system to keep an eye on their remote assets.
