  • WhatsApp Catches Spyware Firm NSO Defying No-Hacking Court Order
    by BeauHD on 08/06/2026 at 6:00 pm

    wiredmikey shares a report from SecurityWeek: Meta-owned communications app WhatsApp says it recently detected and disrupted a spear-phishing attempt linked to spyware company NSO Group. The attack is allegedly in defiance of a court order that bars the spyware maker from targeting WhatsApp. WhatsApp filed a lawsuit against NSO in 2019, after it came to light that a zero-day vulnerability had been exploited to deliver spyware to users. [...] NSO has been seeking to overturn the order blocking it from targeting WhatsApp users, arguing that the company will "suffer irreparable harm." According to WhatsApp, the spyware maker has violated the permanent injunction. The messaging app reported on Monday that it had recently learned of a social engineering attack that attempted to trick users into clicking on malicious links. WhatsApp has only shared a few domains as an indicator of compromise (IoC), but says it was able to link the attack to NSO, pointing to similarities to previously reported one-click phishing campaigns tied to the spyware company. WhatsApp says it also caught the attackers creating test accounts and groups. Those accounts and groups have been disabled, but further action is also being taken. WhatsApp says it is asking a federal court to hold NSO in contempt for allegedly violating a permanent injunction barring it from targeting WhatsApp and its users. The company also said it is making a "significant contribution" to the Spyware Accountability Initiative, a fund aimed at exposing and stopping spyware abuse. Read more of this story at Slashdot.

  • Firefox Merges Support For Vulkan Video Decoding
    by BeauHD on 08/06/2026 at 5:00 pm

    Firefox has merged initial support for Vulkan Video decoding, giving the browser a more cross-platform path for GPU-accelerated video playback beyond Linux's long-running reliance on VA-API. Phoronix reports: Firefox on Linux has long been focused on the Video Acceleration API (VA-API) that isn't universally supported by Linux graphics drivers. This has left to efforts like NVIDIA-VAAPI-Driver to layer VA-API atop NVIDIA NVDEC interfaces to enjoy GPU-accelerated video playback in Firefox. Smaller Arm/embedded graphics drivers also have been largely left out of the game in the VA-API space. But with Vulkan Video we are beginning to see more adoption and in a cross-platform manner. [...] The Firefox 153 release due out in July will have Vulkan Video decoding support available. The Vulkan Video activity in Firefox Git culminated this week with the work of NVIDIA engineer Tymur Boiko and Red Hat's Martin Stransky. Firefox 153.0 is expected for release on 21 July with this Vulkan Video support assuming no last minute issues. Read more of this story at Slashdot.

  • Italy's Bending Spoons, Owner of AOL and Vimeo, Files For Nasdaq IPO
    by BeauHD on 08/06/2026 at 4:25 pm

    Bending Spoons, the Italian app studio behind acquisitions like Eventbrite, Vimeo, WeTransfer, Evernote, and AOL, has filed to go public in the U.S. after growing into a subscription-heavy app conglomerate with more than 500 million monthly active users. TechCrunch reports: In its filing with the Securities and Exchange Commission, Bending Spoons said it ended the year with $1.31 billion in revenue and has generated $601 million in Q1, a 132% year-on-year jump. The company gets the majority of its revenue from subscriptions, which account for 84% of its business. It generated $27.4 million in profit in Q1 2026. The company raised funding at an $11 billion valuation last year, up from $2.8 billion in 2024. In April, Reuters reported that the company could seek a $20 billion valuation with the IPO.

  • Jeff Bezos Is Funding a Wild Hunt for the Brain's 'Core Algorithm'
    by BeauHD on 08/06/2026 at 3:00 pm

    Jeff Bezos is backing Flourish, a new "neuro AI" startup with $500 million in funding and a reported $2.5 billion valuation, that aims to reinvent AI by studying the brain's architecture and building systems that learn continuously while using far less power than today's large language models. The company's long-term bet is that neuroscientists and AI researchers working together can uncover the brain's "core algorithm" and eventually create brain-inspired AI that runs on a tiny fraction of current compute. Wired reports: Rob Williams knows how to pitch Jeff Bezos: You write a press release as if your product has already been built. Bezos reads it and gives a thumbs up or down. Williams went through this process a lot as an executive on Amazon's "S-team," in charge of software products such as Alexa, until his departure last fall. But the pitch he made a few weeks later -- in December 2025 -- was different. Now he was collaborating with Thomas Reardon, a neuroscientist and repeat startup founder, and approaching Bezos as a funder, not a boss. Here's what Bezos, sitting on his yacht somewhere, read while Williams anxiously watched on Zoom: "Flourish is a neuro AI company that is solving the two most difficult problems facing AI today: power efficiency and continuous learning. We are building Cortex AI, the first synthetic intelligence system designed to match the computational capacity, learning efficiency, and power budget of the human brain." A month later, I'm lunching with Reardon and Williams in the Flatiron neighborhood in New York City. Reardon gets right to the point. AI has dug itself into a hole, he says. Though increasingly powerful, large language models are greedy consumers of computer power and data. Though the inspiration for LLMs was rooted in biology, current frontier models have little in common with the human brain. A person uses about 20 watts of energy to process information; a single chip in an AI training cluster uses more than 30 times that amount. The hyperscalers require thousands of chips and gigawatts of energy, enough to power small cities. And those models need to suck up virtually all of what humans have written. Each new model requires more, more, more. For all of that, the models don't learn. Once you train them, they're stuck. The goal, Reardon tells me, is to build "a synthetic artificial intelligence brain that runs on 50 watts or less." It should adapt to its conditions, be as nimble as a human mind, and burn a tiny fraction of an LLM's compute power and energy. The proof of concept is thriving inside our skulls. "There's something fundamentally wrong with saying, "I need to basically read every book ever written 20 times over in order to learn English,'" Reardon says. "A human baby does it with a couple hundred thousand utterances." Reardon and Williams haven't figured out yet how to build systems that match the magic of a human brain. What they have is a belief that an expert, well-resourced team -- of AI researchers and neuroscientists working essentially side by side -- can find the answer. The neuroscientists will conduct original wet lab experiments with some of the most advanced lab equipment available, to hunt for usable intel on the brain's architecture. They plan to release the models they're currently developing as near-term products on the path to a full reinvention of AI. The fuzziness of the proposal didn't bother Jeff Bezos. After reading Williams' two-pager, he chipped in $50 million. Other funding came from Lux Capital, Google Ventures, and Catalio, among others. Bezos then almost doubled his initial stake and told Reardon he'd have given more if they'd asked. Now with a war chest of $500 million and a reported valuation of $2.5 billion, Flourish just needs to invent a new way to do AI. Read more of this story at Slashdot.

  • Ruby Fights Supply-Chain Attacks With Filter Offering 'Cooldown' Before Installing New Packages
    by EditorDavid on 08/06/2026 at 11:34 am

    Most supply-chain attacks using Ruby's package hosting site "exploit a narrow window," according to a new blog post form Ruby core maintainer Hiroshi Shibata. So its packaging-managing Bundler tool now offers a filter that blocks new version until it's been public "for at least N days. Releases too new to have been scrutinized are passed over in favor of ones that have aged past the window." The feature was designed in the open, drawing on how other ecosystems approach the same problem. It is opt-in, and complements rather than replaces existing defenses like mandatory 2FA and trusted publishing... Cooldown is unset by default, so a project without it keeps resolving to the newest versions.... Passing 0 disables cooldown for the run... Cooldown is most useful as one part of the wider security investment happening on rubygems.org. The registry now validates gem contents at push time and checks logins against Have I Been Pwned so that compromised passwords cannot be reused, work described in Protecting rubygems.org from the outside in. A dedicated team is running AI-assisted vulnerability scanning against the most critical gems, backed by Alpha Omega and Anthropic, and the direction of all of this is tracked on a public roadmap. Trusted publishing and mandatory 2FA already raise the bar for who can push a release in the first place. Read more of this story at Slashdot.

  • A San Francisco Burglar Escaped in a Robotaxi - and Police Still Can't Find Him
    by EditorDavid on 08/06/2026 at 7:34 am

    A burglar took a self-driving Waymo taxi to rob a San Francisco yoga studio this past January, reports TechCrunch — "and police have still not caught them." Even the police officer assigned to the case thought it would be easier to solve, notes The San Francisco Chronicle, since Waymos are outfitted with multiple high-definition cameras and require users to make accounts with their credit card numbers: It's common for officers to seek video footage of a crime from any of the Waymos, Teslas and other high-tech vehicles that record their surroundings. That information can be crucial for identifying suspects or creating a reliable timeline of events. At times, police will go so far as to obtain search warrants to tow the vehicle "witnesses" to ensure they don't lose valuable video evidence. In the Hot 8 Yoga burglary case, San Francisco police issued a search warrant that forced Waymo to turn over information on the account that ordered the ride and video footage from the white Jaguar that served as the getaway car, police records show. Faye said that he couldn't discuss certain details of the case, but that the Waymo user's account information didn't lead police to the suspect. In general, he said, it's not unusual for a criminal to order a service with stolen information or a burner phone. The video evidence didn't help much either, Faye said. He said that the company had not retained interior footage of the car by the time the search warrant was filed in April and that it had kept the faces seen outside the car blurred for privacy reasons... Waymo does not publicly disclose how long it retains video footage. The company blurs faces and license plates in the public-facing images it uses in a database designed for research.... Last year in Los Angeles, a person allegedly robbed a grocery store before hopping in a Waymo. Officers were able to chase down the vehicle after the suspect got inside, and the car pulled itself over after police turned on the car's emergency lights, according to Los Angeles-area news outlets. "Farah Issa, studio manager of Hot 8 Yoga, showed the Chronicle a copy of the surveillance video from her phone, noting how the Waymo dropped off the suspect and waited for him to finish the burglary before taking off again."
