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.
Visualizing The Power Of The World's Supercomputers BY TYLER DURDEN FRIDAY, JAN 21, 2022 - 04:15 AM A supercomputer is a machine that is built to handle billions, if not trillions of calculations at once. Each supercomputer is actually made up of many individual computers (known as nodes) that work together in parallel. A common metric for measuring the performance of these machines is flops , or floating point operations per second . In this visualization, Visual Capitalist's Marcus Lu uses November 2021 data from TOP500 to visualize the computing power of the world’s top five supercomputers. For added context, a number of modern consumer devices were included in the comparison. Ranking by Teraflops Because supercomputers can achieve over one quadrillion flops, and consumer devices are much less powerful, we’ve used teraflops as our comparison metric. 1 teraflop = 1,000,000,000,000 (1 trillion) flops. Supercomputer Fugaku was completed in March 202
Too Much Power to the People? A Food Safety Site Tests the Limits Several national chain restaurants have been the target of complaints on IWasPoisoned.com since the site began in 2009. By KEVIN ROOSE FEB. 13, 2018 Dan Laptev, an electronics analyst, was making his way through the Charlotte, N.C., airport this month when he stopped at Starbucks for a light dinner — a ham-and-cheese sandwich and a cup of hot chocolate. He ate, drank, boarded his flight and got home. And that’s when the trouble started. Mr. Laptev spent much of that night hunched over the toilet with a violently upset stomach. Suspecting his Starbucks meal as the source of his ills, he sent a complaint through the company’s website, but got only an automated form email back. So he did the next best thing: He logged on to his computer and went to IWasPoisoned.com, a website that allows users to post reports of food poisoning, and submitted his saga. “I wanted to let people know to stop eating at Star
