For at least a decade, a car theft trick known as a “relay attack” has been the modern equivalent of hot-wiring: a cheap and relatively easy technique to steal hundreds of models of vehicles. A more recent upgrade to the radio protocol in cars' keyless entry systems known as ultra-wideband communications, rolled out to some high-end cars including the latest Tesla Model 3, has been heralded as the fix for that ubiquitous form of grand theft auto. But when one group of Chinese researchers actually checked whether it's still possible to perform relay attacks against the latest Tesla and a collection of other cars that support that next-gen radio protocol, they found that they're as stealable as ever.

In a video shared with WIRED, researchers at the Beijing-based automotive cybersecurity firm GoGoByte demonstrated that they could carry out a relay attack against the latest Tesla Model 3 despite its upgrade to an ultra-wideband keyless entry system, instantly unlocking it with less than a hundred dollars worth of radio equipment. Since the Tesla 3's keyless entry system also controls the car's immobilizer feature designed to prevent its theft, that means a radio hacker could start the car and drive it away in seconds—unless the driver has enabled Tesla's optional, off-by-default PIN-to-drive feature that requires the owner to enter a four-digit code before starting the car.

As new diabetes and weight-loss drugs help patients curb appetites and shed pounds, food manufacturers are looking for new ways to keep their bottom lines plump.

Millions of Americans have begun taking the pricey new drugs—particularly Mounjaro, Ozempic, Wegovy, and Zepbound—and millions more are expected to go on them in the coming years. As such, food makers are bracing for slimmer sales. In a report earlier this month, Morgan Stanley's tobacco and packaged food analyst Pamela Kaufman said the drugs are expected to affect both the amounts and the types of food people eat, taking a bite out of the food and drink industry's profits.

"In Morgan Stanley Research surveys, people taking weight-loss drugs were found to eat less food in general, while half slashed their consumption of sugary drinks, alcohol, confections and salty snacks, and nearly a quarter stopped drinking alcohol completely," Kaufman said. Restaurants that sell unhealthy foods, particularly chains, may face long-term business risks, the report noted. Around 75 percent of survey respondents taking weight-loss drugs said they had cut back on going to pizza and fast food restaurants.
