Two years ago when “Michael,” an owner of cryptocurrency, contacted Joe Grand to help recover access to about $2 million worth of bitcoin he stored in encrypted format on his computer, Grand turned him down.

Michael, who is based in Europe and asked to remain anonymous, stored the cryptocurrency in a password-protected digital wallet. He generated a password using the RoboForm password manager and stored that password in a file encrypted with a tool called TrueCrypt. At some point, that file got corrupted, and Michael lost access to the 20-character password he had generated to secure his 43.6 BTC (worth a total of about 4,000 euros, or $5,300, in 2013). Michael used the RoboForm password manager to generate the password but did not store it in his manager. He worried that someone would hack his computer and obtain the password.

“At [that] time, I was really paranoid with my security,” he laughs.

Last week, the Biden administration announced it would levy dramatic new tariffs on electric vehicles, electric vehicle batteries, and battery components imported into the United States from China. The move kicked off another round of global debate on how best to push the transportation industry toward an emissions-free future, and how global automotive manufacturers outside of China should compete with the Asian country’s well-engineered and low-cost car options.

But what is an electric vehicle exactly? China has dominated bicycle manufacturing, too; it was responsible for some 80 percent of US bicycle imports in 2021, according to one report. In cycling circles, the US’s new trade policies have raised questions about how much bicycle companies will have to pay to get Chinese-made bicycles and components into the US, and whether any new costs will get passed on to US customers.

On Wednesday, the Office of the United States Trade Representative—the US agency that creates trade policy—clarified that ebike batteries would be affected by the new policy, too.

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.

This June, approximately 150 motorcycles will thunder down Route 9W in Saugerties, New York, for Ryan’s Ride for Recovery. Organized by Vince Kelder and his family, the barbecue and raffle will raise money to support their sober-living facility and honor their son who tragically died from a heroin overdose in 2015 after a yearslong drug addiction.

The Kelders established Raising Your Awareness about Narcotics (RYAN) to help others struggling with substance-use disorder. For years, the organization has relied on Eventbrite, an event management and ticketing website, to arrange its events. This year, however, alongside listings for Ryan’s Ride and other addiction recovery events, Eventbrite surfaced listings peddling illegal sales of prescription drugs like Xanax, Valium, and oxycodone.

“It’s criminal,” Vince Kelder says. “They’re preying on people trying to get their lives back together.”

In July last year, OpenAI announced the formation of a new research team that would prepare for the advent of supersmart artificial intelligence capable of outwitting and overpowering its creators. Ilya Sutskever, OpenAI’s chief scientist and one of the company’s co-founders, was named as the co-lead of this new team. OpenAI said the team would receive 20 percent of its computing power.

Now OpenAI’s “superalignment team” is no more, the company confirms. That comes after the departures of several researchers involved, Tuesday’s news that Sutskever was leaving the company, and the resignation of the team’s other co-lead. The group’s work will be absorbed into OpenAI’s other research efforts.

Billy Restey is a digital artist who runs a studio in Seattle. But after hours, he hunts for rare chunks of bitcoin. He does it for the thrill. “It’s like collecting Magic: The Gathering or Pokémon cards,” says Restey. “It’s that excitement of, like, what if I catch something rare?”

In the same way a dollar is made up of 100 cents, one bitcoin is composed of 100 million satoshis—or sats, for short. But not all sats are made equal. Those produced in the year bitcoin was created are considered vintage, like a fine wine. Other coveted sats were part of transactions made by bitcoin’s inventor. Some correspond with a particular transaction milestone. These and various other properties make some sats more scarce than others—and therefore more valuable. The very rarest can sell for tens of millions of times their face value; in April, a single sat, normally worth $0.0006, sold for $2.1 million.
