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
Another interesting factor in attacks on the U.S. critical infrastructure is the exploiting of SCADAS. It’s been evidenced quite a few times that these have been compromised.
Here is one such example: UPDATE 3: U.S. probes cyber attack on water system
More than 10,000 people in Arkansas were dumped into a blackout Sunday following an attack on that state’s electric grid, the FBI said today, the third such attack in recent weeks. In August, a major transmission line in the region, around Cabot, Ark., was deliberately cut.
The FBI said that two power poles had been intentionally cut in Lonoke County on Sunday, resulting in the outage.
The FBI said it would pay a $25,000 reward for information about the attacks.
And for good reason. The FBI suspects these attacks are linked with a third incident in September. Continue reading
