So-called smart cities, with wireless sensors controlling everything from traffic lights to water management, may be vulnerable to cyberattacks, according to a computer security expert.
Last year, Cesar Cerrudo, an Argentine security researcher and chief technology officer at IOActive Labs, demonstrated how 200,000 traffic control sensors installed in major hubs like Washington, New York, Melbourne and Lyon were vulnerable to attack. Mr. Cerrudo showed how information coming from these sensors could be intercepted from 1500 feet away — or even by drone — because one company had failed to encrypt its traffic.
Just last Saturday, Mr. Cerrudo tested the same traffic sensors in San Francisco and found that, one year later, they were still not encrypted. Continue reading
