One of the world’s most active ransomware groups has taken an unusual—if not unprecedented—tactic to pressure one of its victims to pay up: reporting the victim to the US Securities and Exchange Commission.

The pressure tactic came to light in a post published on Wednesday on the dark web site run by AlphV, a ransomware crime syndicate that’s been in operation for two years. After first claiming to have breached the network of the publicly traded digital lending company MeridianLink, AlphV officials posted a screenshot of a complaint it said it filed with the SEC through the agency’s website. Under a recently adopted rule that goes into effect next month, publicly traded companies must file an SEC disclosure within four days of learning of a security incident that had a “material” impact on their business.

“We want to bring to your attention a concerning issue regarding MeridianLink's compliance with the recently adopted cybersecurity incident disclosure rules,” AlphV officials wrote in the complaint. “It has come to our attention that MeridianLink, in light of a significant breach compromising customer data and operational information, has failed to file the requisite disclosure under item 1.05 of form 8-K within the stipulated four business days, as mandated by the new SEC rules.”

What do you get the supercar that has everything? McLaren must have been thinking about that question when it came time to give the already rather good 720S a bit of a midlife refresh. The answer is more power, less weight, and a raft of updates here and there that make the new McLaren 750S more useable but also even better on track, if that's your thing.

Starting from a standard configuration, a 750S weighs 3,062 lbs (1,388 kg), 66 lbs (30 kg) less than the car it's replacing. But if you select the right combination of options, from single-piece carbon fiber racing seats to titanium wheel bolts, you can trim that down even further—McLaren says to as little as 2,815 lbs (1,277 kg), but that's a dry weight.

Regardless, the all-carbon fiber construction results in a car that's both very stiff and lighter than the competition. And the penalty for switching to a retractable hardtop roof is just 108 lbs (50 kg), although it does bring the car's center of gravity up a smidge.

UnitedHealthcare, the largest health insurance company in the US, is allegedly using a deeply flawed AI algorithm to override doctors' judgments and wrongfully deny critical health coverage to elderly patients. This has resulted in patients being kicked out of rehabilitation programs and care facilities far too early, forcing them to drain their life savings to obtain needed care that should be covered under their government-funded Medicare Advantage Plan.

That's all according to a lawsuit filed this week in the US District Court for the District of Minnesota. The lawsuit is brought by the estates of two deceased people who were denied health coverage by UnitedHealth. The suit also seeks class-action status for similarly situated people, of which there may be tens of thousands across the country.

The lawsuit lands alongside an investigation by Stat News that largely backs the lawsuit's claims. The investigation's findings stem from internal documents and communications the outlet obtained, as well as interviews with former employees of NaviHealth, the UnitedHealth subsidiary that developed the AI algorithm called nH Predict.

On Wednesday, a collaborative whiteboard app maker called "tldraw" made waves online by releasing a prototype of a feature called "Make it Real" that lets users draw an image of software and bring it to life using AI. The feature uses OpenAI's GPT-4V API to visually interpret a vector drawing into functioning Tailwind CSS and JavaScript web code that can replicate user interfaces or even create simple implementations of games like Breakout.

"I think I need to go lie down," posted designer Kevin Cannon at the start of a viral X thread that featured the creation of functioning sliders that rotate objects on screen, an interface for changing object colors, and a working game of tic-tac-toe. Soon, others followed with demonstrations of drawing a clone of Breakout, creating a working dial clock that ticks, drawing the snake game, making a Pong game, interpreting a visual state chart, and much more.

Users can experiment with a live demo of Make It Real online. However, running it requires providing an API key from OpenAI, which is a security risk. If others intercept your API key, they could use it to rack up a very large bill in your name (OpenAI charges by the amount of data moving into and out of its API). Those technically inclined can run the code locally, but it will still require OpenAI API access.

BOCA CHICA BEACH, Texas—The launch of SpaceX's second full-size Starship rocket from South Texas is now scheduled for Saturday, a day later than previously planned, according to company founder Elon Musk.

This 24-hour delay will allow time for SpaceX technicians at the company's launch facility, known as Starbase, to replace a component on the rocket's stainless steel Super Heavy booster. There is a 20-minute launch window on Saturday, opening at 7 am CST (13:00 UTC), shortly after sunrise in South Texas.

A delay at this point is unsurprising. Starship is a complex launch vehicle with a sum of 39 methane-burning engines, each producing roughly a half-million pounds of thrust, powering its booster stage and upper stage. And this is only the second test flight of SpaceX's new full-scale, nearly 400-foot-tall (121-meter) rocket, the largest launch vehicle ever built.

A bang, a gunshot, a "pop of death": Some owners of Sonos' Arc and second-gen Beam soundbars have been dealing with a striking audio disruption with their audio systems since at least December 2020.

The issue now has a fix, and it should already be available to users. Updating a Sonos mobile or desktop app and then checking for system updates should push the changes to Sonos speakers.

A Sonos staff member writes that the Arc and Beam soundbars "in certain home theater configurations process Dolby MAT," which delivers Atmos audio over HDMI connections. Sonos products could receive corrupted audio from that connection but were failing to filter out those bits, playing them instead. The corrupted audio "can manifest as a popping sound." The Sonos devices' improved Dolby decoder should no longer force listeners to hear what it sounds like when digital audio transmissions go awry.

On Wednesday, Replicate developer Charlie Holtz combined GPT-4 Vision (commonly called GPT-4V) and ElevenLabs voice cloning technology to create an unauthorized AI version of the famous naturalist David Attenborough narrating Holtz's every move on camera. As of Thursday afternoon, the X post describing the stunt had garnered over 21,000 likes.

"Here we have a remarkable specimen of Homo sapiens distinguished by his silver circular spectacles and a mane of tousled curly locks," the false Attenborough says in the demo as Holtz looks on with a grin. "He's wearing what appears to be a blue fabric covering, which can only be assumed to be part of his mating display."

"Look closely at the subtle arch of his eyebrow," it continues, as if narrating a BBC wildlife documentary. "It's as if he's in the midst of an intricate ritual of curiosity or skepticism. The backdrop suggests a sheltered habitat, possibly a communal feeding area or watering hole."
