A pair of security analysts recently claimed to have come across a technique to instill bogus messages, a few witty and others possibly threatening, into car satellite navigation systems. The two security experts known as Andrea Barisani, chief security engineer for Inverse Path, and Daniele Bianco, a hardware hacker at Inverse Path, utilized off-the-shelf equipment to send out messages to their car satellite navigation system cautioning about circumstances starting from misty weather to terrorist attacks. They brought forth their result at the recent CanSecWest–a security conference.
Barisani & Bianco transmitted the messages over Radio Data System (RDS), a standard brought about in Europe however also utilized in North America that lets FM radio stations send out data over a sliver of spectrum that is operated alongside each FM channel. RDS is claimed to be capable of keeping info like the name of the radio station. It is also claimed to be capable of sending out traffic info.
Barisani maintained that for the past couple of years, satellite navigation systems have started getting that data so that users may be kept on the alert about traffic or weather conditions. Barisani and Bianco claimed to have detected that they are capable of building a device that sends out over the RDS channel. Via trial and error, they found that sending particular code numbers converted into certain cautions that are shown on the satellite navigation system.
A few were witty as one code number warns users of a bullfight in progress, while ano-ther one points toward delays because of a parade. However a few of them did not seem to be so amusing. One alerts users about a terrorist incident, whereas one hints at a bomb alert, and another alerts an air crash.
