A malicious technology can play tricks self - driving cars into " hallucinate " phantom vehicles and slue perilously off - course to get out of their style , researchers have identify .
The raw cab , dubbed " MadRadar , " can also hide actual cars from on - vehicle radar sensors and gull a ego - driving car into thinking a existent cable car has jerked off course . The scientist reported their finding in a match - review newspaper , which will be represent Feb. 26 at the connection and Distributed System Security ( NDSS ) Symposium 2024 in San Diego .
Scientists demonstrated three attack methods using MadRadar and urged automakers to rethink how they protect self-driving cars and their inhabitants.
" Without knowing much about the targeted car ’s radar system , we can make a fake fomite come along out of nowhere or make an real vehicle disappear in real - worldly concern experimentation , " conduce authorMiroslav Pajic , a professor of electrical and data processor engineering at Duke University in North Carolina , enunciate in astatement . " We ’re not building these systems to hurt anyone , we ’re present the live problems with current radar organization to show that we want to fundamentally modify how we design them . "

ego - repulse auto will increasingly take to U.S. roads over the next few years . Mercedes Benzbecame the first automaker in the U.S. to receive approval forLevel 3 self - drive carsin January 2023 — meaning vehicle can do all the driving under sealed conditions . Approval was grant by Nevada state governor for use on U.S. public freeways . Many electric vehicles , including Tesla ’s , are fitted with automation or autopilot system of rules .
unlike cars apply different systems by conception , so it ’s improbable any two vehicles will apply the same operating parameters even if they are the same make and model of car , the scientists said in the statement . They may , for exercise , apply different operating frequencies or take measure at marginally different interval — measures that are build in to protect against radar - spoofing flak .
MadRadar , however , can accurately detect a car ’s radar parameters in less than a twenty-five percent of a second from a remote position and then send out its own radar signaling to fool the aim ’s radar . The scientists did not reveal the specific mechanics of the attack ahead of their paper ’s issue at NDSS .
They did , however , show three attack type on real - world radar systems in moving cars . In one attack , MadRadar charge signals to the target car to slang it into think another fomite was in its way . It did this by changing the signal so it mimicked what the await contact might look like .

— NASA and DARPA flew ' observational ' self - fly helicopters to see if they could avoid crashing into other virtual aircraft
— World ’s 1st galvanic flying passenger ship could ' revolutionize how we move on pee '
A 2d plan of attack gull a target ’s radar into call back there was no passing car , when in realness there was one . MadRadar did this by add masking signal around the overtake railcar ’s location to create a " brilliant spot " and confuse the radar organisation .
In the third attack , the research worker combine these two attack and gull a car into remember a substantial car had on the spur of the moment changed course . " ideate adaptive sail ascendancy , which uses radio detection and ranging , believing that the car in front of me was speeding up , have your own elevator car to speed up , when in reality it was n’t changing upper at all , " Pajic allege . " If this were done at Nox , by the time your car ’s television camera enter it out you ’d be in trouble . "
The results , the scientists aver , reveal that car producer need to rethink how they follow through anti - radiolocation - spoofing protections in their vehicles . Manufacturers should take stride to upright safeguard vehicle and their habitant , they added , though the squad did n’t specify how .
