ATLANTA — Cybersecurity
has quickly become a priority for large corporations, businesses, and
individuals alike in recent years. It seems like another major data breach is
being reported every other week, and personal online accounts are often
compromised by malicious actors. Now, a new study out of the Georgia
Institute of Technology has found that hackers may soon be able to cause major traffic problems in the real world by hacking
and stranding internet-connected cars.
The study’s authors theorize that hackers would only have to
shut down a portion of cars on the road in a busy city like Manhattan during
rush hour to completely shut down traffic and gridlock the city. Researchers
hope that their findings will spark a more detailed analysis of automotive cybersecurity, especially moving forward as cars
become more and more high tech.
“Unlike most of the data breaches we hear about, hacked cars
have physical consequences,” says co-author Peter Yunker in a release.
Yunker and his team say that right now the automotive
cybersecurity sector is focusing too much on hacks that target one car, and
they need to consider the possibility that a higher number of cars being hacked at the same time could lead to
“With cars, one of the worrying things is that currently there
is effectively one central computing system, and a lot runs through it. You
don’t necessarily have separate systems to run your car and run your satellite
radio. If you can get into one, you may be able to get into the other,”
explains co-author Jesse Silverberg
The research team ran simulations on Manhattan, and found they
were able to bring all traffic to a complete freeze by randomly stalling 20% of
the cars on the road at rush hour. Hacking just 10% of cars on the road would stop
traffic enough to prevent emergency vehicles from moving around.
“At 20 percent, the city has been broken up into small islands,
where you may be able to inch around a few blocks, but no one would be able to
move across town,” says graduate research assistant David Yanni.
Researchers say that Manhattan is actually a less than ideal
target for car hackers, and more damage may be done with less cars in other
“Manhattan has a nice grid, and that makes traffic more
efficient. Looking at cities without large grids like Atlanta, Boston, or Los
Angeles, and we think hackers could do worse harm because a grid makes you more
robust with redundancies to get to the same places down many different routes,”
Furthermore, the study’s authors say they did not account for any outside
factors, such as traffic spillover from other blocked streets or public panic,
when compiling their findings. With this in mind, they say that its likely that
significantly less than 20% of all cars would be needed to gridlock a city and
cause a panic.
The study is published in the journal Physical Review E.
World’s 1st remote brain surgery via 5G network performed in China Published time: 17 Mar, 2019 13:12 · A Chinese surgeon has performed the world’s first remote brain surgery using 5G technology, with the patient 3,000km away from the operating doctor. Dr. Ling Zhipei remotely implanted a neurostimulator into his patient’s brain on Saturday, Chinese state-run media reports . The surgeon manipulated the instruments in the Beijing-based PLAGH hospital from a clinic subsidiary on the southern Hainan island, located 3,000km away. The surgery is said to have lasted three hours and ended successfully. The patient, suffering from Parkinson’s disease, is said to be feeling well after the pioneering operation. The doctor used a computer connected to the next-generation 5G network developed by Chinese tech giant Huawei. The new device enabled a near real-time connection, according to Dr. Ling. “You barely feel that the patient is 3,000 kilometers away,” he said.
Beijing Orders Alibaba To Dump Media Assets That Rival China's Propaganda Machine BY TYLER DURDEN MONDAY, MAR 15, 2021 - 07:30 PM Beijing is reviving its crackdown on the country's biggest tech firms, reminding the world that the CCP is still focused on neutralizing any and all threats to its control of the Chinese economy and its people. Even after amending China's official ideology to include entrepreneurs among the protected classes represented by the CCP (in addition to workers, farmers and soldiers), Beijing, with President Xi at its center, has apparently decided that Chinese tech firms won't follow the American model after all. Instead, their growth and competitive capabilities will be curtailed for the sake of stability at home. After Tencent was censured and strict new requirements were officailly imposed on Alibaba-owned Ant Group that will prevent the company from growing , the Wall Street Journal reports that next up on Beijing's to-do lis
From Amazon to Wal-Mart, digital retail is producing more jobs and higher pay Written by Mitchell Schnurman, Business columnist May 30, 2017 Retail trade is one of the biggest job sectors in America, and the vast majority of those workers still clock in at brick-and-mortar stores. But the big growth is coming from e-commerce, which happens to pay a lot better, too. This is a promising development for retail workers who worry about thousands of store closings and the march of automation. E-commerce also offers a potential antidote to years of low productivity growth and income stagnation. “If this new pattern continues, it will raise real wages across the economy and rejuvenate the middle class,” said a report by economist Michael Mandel of the Progressive Policy Institute in Washington. By his definition, e-commerce includes online shopping, mail order and warehousing. That’s a more expansive category than usual and was created to capture the growth in what M
