  • Windows 11 Identifier Code Used to Arrest 19-Year-Old Over Alleged Ransomware Spree
    by EditorDavid on 05/07/2026 at 5:54 pm

    America's Justice Department and FBI teamed joined Finland's National Bureau of Investigation to arrest a teenager they say is part of one of the world's biggest cybercrime syndicates, reports Tom's Hardware. The "Scattered Spider" syndicate has extorted over $100 million in ransom payments, according to Department of Justice figures: 19-year-old Peter Stokes is a dual U.S.-Estonian citizen who was trying to board a flight to Japan from Helsinki, when law enforcement caught up with him. [T]he main criminal complaint against Stokes stems from a May 2025 attack on a luxury jewelry dealer based in the United States. The attackers apparently called the company's IT helpdesk using Google Voice, posing as employees. They were able to convince the help desk into resetting their credentials, which allowed them to infiltrate three accounts, two of which had admin privileges. From there, the group, allegedly including Stokes, stole important data and held the jeweler at ransom, demanding an $8 million payment in crypto. The company ultimately regained access to their infrastructure and avoided paying the ransom, but the operational disruption still caused a purported $2 million in losses. This served as the spark that led to Stokes' eventual arrest in Helsinki, as the prosecutors slowly followed the paper and digital trail laid by the attackers. Microsoft played a key role in the process by providing GDID [Global Device Identifier] data to the FBI to help them apprehend the alleged criminal... [I]t's a unique identifier assigned to every Windows install that tracks device-specific telemetry. It's the reason why sometimes changing a major component in your PC can revoke your Windows license... [T]he court documents from the case reveal that Stokes used Windows, from which investigators were able to link his physical hardware to specific internet activity and locations... Stokes' web activity, videogame history, IP addresses, tool usage (including Ngrok), Azure status, and more were logged with timestamps, and were provided to the investigators by Microsoft... Stokes was carrying two hard drives full of incriminating evidence with him when boarding his flight to Japan... His real identity has actually been known since 2024, but since he was a minor living across Estonia and the UAE at the time, he could only be monitored until the time was right. The official criminal complaint even includes a selfie photo that Stokes posted on Snapchat (hiding his face behind dozens of hundred dollar bills). It then notes that behind Stokes the wallpaper, carpet, and furniture match New York's Empire Hotel — and that Stokes had visited the hotel's web site in Germany before then flying to New York... "Following the arrest, Stokes was extradited to the U.S., where he appeared in front of a federal court in Chicago for the first time on June 30, 2026, and he remains in custody," adds Tom's Hardware. "The accused is now awaiting trial, having been charged with conspiracy, cyber intrusion, and fraud..." Read more of this story at Slashdot.

  • Short Story Accused of Being AI-written Goes on to Win Contest's First Prize
    by EditorDavid on 05/07/2026 at 4:34 pm

    "A story widely accused on social media of being written using AI has gone on to win the overall Commonwealth short story prize," reports the Guardian. In mid-May the story had been selected as a regional winner, but with critics on X and Bluesky "claiming it showed 'obvious markers' of AI use." In the wake of the controversy, the Commonwealth Foundation conducted a review of the regional winners, which it said involved looking at drafts, time-stamped documents and notes. "We are satisfied with the testimonies of our writers and their confirmation that AI was not used in their writing," said foundation director-general Razmi Farook... Judging chair Louise Doughty described Nazir's piece as "an original, poetic and deeply moving story...." In a film released by the Commonwealth Foundation on Tuesday, Nazir... adds that he wrote six or seven drafts of his prize-winning story, and also speaks about his use of speech-to-text software, explaining that he could only see three or four lines of text on his phone screen at any one time, so he would perfect each line before moving on, which is how his story ended up being "highly polished"... Initial social media reactions to the Commonwealth Foundation's announcement of Nazir's win were negative, with one X user writing: "immensely disappointing and disheartening. it feels like they wanted to stick to their guns after the entire GenAI uproar. I might think twice now before submitting my stories here". After Nazir was announced as the regional winner in May, some social media users reported running his story through AI-detection software. "Pangram flags at 100% but also, come on, if you know you know", said Wharton professor Ethan Mollick. However, the reliability of AI-detection software has been called into question. In a statement to the Guardian, Farook said that "rather than surrender our judgment to AI-detection software, we asked our winners to show their working drafts, outlines, the evidence of an artistic journey. That software, it must be said, is not infallible: it returns inconsistent verdicts and, in doing so, corrodes the very trust on which a prize depends." "When the machine's default voice is the metropolitan one, the writer who does not fit the expected mould is the first to fall under suspicion," she added. "The more startling her gift, the more her unfamiliar brilliance unsettles, the more readily she is accused of being a machine. A young writer in Kingston or Kolkata, in Kuala Lumpur or Kigali, must now prove not only her talent but her very humanity." Nazir's story beat 7,806 other stories, the video points out (adding that their prize "demonstrates that in a world increasingly driven by algorithms, the human voice still matters.") The Guardian notes that the winning story "includes multiple 'not x, but y' constructions and lists of three, which some consider to be signs of AI use," and that critics also drew attention to particular lines like "Sun on galvanise is a cruel instrument" and "Marsha lived two bends down." In a new interview with the Times of India Nazir says "Now I'm frightened about publishing new work because the attacks haven't stopped." Q: Which passages attracted the most criticism, and why do you think they were misunderstood? Nazir: People criticised a line where I wrote: 'She had the kind of walking that made benches become men.' That's magical realism. Think Salman Rushdie or Gabriel Garcia Marquez. It's a literary technique. In my story, the character 'Zoongie' believes she is so beautiful that even when no men are around, she imagines the benches becoming men who admire her. It exists only in her imagination. People interpreted it literally. There was another line about light reflecting from a sink. That came directly from my childhood. Our kitchen faced east, and my mother liked to keep everything spotless. We used to polish the sink, and when the morning sun hit it, it glittered brightly. People claimed that the image must have been AI-generated. But it's from my lived experience... I've lived with diabetes for 62 years, which has damaged the nerves in my fingers and feet, and I'm currently undergoing chemotherapy. That's why I began using speech-to-text on my Android phone... I hope this episode leads to a better understanding of the difference between assistive technology and AI-generated writing... Q: Many acclaimed writers like Ursula K Le Guin, Mary Shelley, and JRR Tolkien have also been falsely flagged by AI detectors. Where does this leave writers? Nazir: What these AI detectors are saying is that if a piece of writing is too polished, it must have been written by AI. I refuse to accept that. AI was trained on human writing. Large language models, to me, are tools, much like a word processor. They don't replace the human spirit behind creative writing. Ask an AI to write a prize-winning story on its own and see what it produces. You still need human imagination and judgment to create literature. Nazir added, "What I don't understand is why people continue to question the judges' decision." Read more of this story at Slashdot.

  • GoDaddy Warns India's Crackdown on Fake Site Registrars Could Upend Internet Privacy Everywhere
    by EditorDavid on 05/07/2026 at 3:34 pm

    "The internet is filled with fakes," writes Gizmodo. "A court in India is setting out to address the problem by requiring more transparency from domain registrars to make it easier to crack down on fraud. And while the intentions might be good, Reuters is reporting that major American domain registrar GoDaddy is sounding the warning bells that the court's decision could fundamentally reshape the internet well beyond India's borders." GoDaddy argues the move would even make the internet less safe, reports Reuters : [Online fraud] is a key challenge for Prime Minister Narendra Modi's government, which last year received 2.4 million complaints of alleged cyber fraud amounting to $2.4 billion. Starting in 2019, lawsuits were brought by dozens of Indian and global firms — Amazon against fake shopping sites trading on its name and McDonald's complaining against bogus sites offering franchises. [More than 20 companies filed a complaint, the article notes, including Microsoft.] In December, an Indian court blocked more than 1,100 such websites. The New Delhi judge however went further, ordering sweeping new measures that tech experts say have rewritten rules of internet governance: Domain sellers should not offer buyers free privacy protection by default, the buyer's details should be released to anyone with a "legitimate interest" within 72 hours, and website addresses that are variations of protected brand names must be prohibited. U.S.-based GoDaddy has challenged the directives before a larger bench of judges at the Delhi High Court, according to a Reuters review of non-public filings. It says the ruling will affect legitimate businesses that have names similar to big brands. Stopping privacy-by-default features, GoDaddy said, will result in public disclosure of name, address, telephone and email of legitimate website owners, exposing them to "foreseeable privacy and security risks" such as stalking and harassment. As domain names operate globally, not locally, the order could force GoDaddy to regulate website addresses across the world, it said. On the court's order imposing a 72-hour deadline on companies to provide registration details to anyone with "legitimate interest", GoDaddy argues it has no wherewithal to assess who has legitimate interest or not. The "commercially destabilising" directives may force domain name companies to "exit India", said one of GoDaddy's appeal documents that ran into 5,121 pages... GoDaddy rivals, Arizona-based Namecheap and Netherlands-based Hosting Concepts, have also challenged the New Delhi ruling, court records show, although Reuters could not ascertain details of their appeals... GoDaddy argues that diluting the privacy feature will run contrary to India's data protection law and the European Union GDPR law which mandates a "privacy by default" approach. Farzaneh Badii, a New York-based researcher on internet governance, criticised the New Delhi ruling, noting that Europe redacted such details because publishing them had been abused by harassment and targeted phishing. "The people exposed will be journalists, activists, small business owners, and private individuals. The brand impersonators will not," she said... While the sweeping December directives were issued by a court, they followed government's submissions, documents showed... The judges will hear the appeals on July 16. GoDaddy manages 80 million domains and serves over 20 million users, the article points out, with annual revenue over $5 billion. Read more of this story at Slashdot.

  • EV Batteries Defy Expectations, Last Hundreds of Thousands of Miles
    by EditorDavid on 05/07/2026 at 12:34 pm

    247,000 miles on an EV battery? So says the owner of a U.K.-based used-car sales company that specializes in Evs, who tells the Wall Street Journal EV batteries keep performing well even after several hundred thousand miles. "They are proving themselves to be exceptionally reliable." After five years on the road, the average EV will still be able to drive up to 95% of its original range, according to Recurrent, a data-science company that provides a battery-monitoring tool for EVs — better than many in the auto industry expected... Potential new car buyers' fear of having to pay for a battery replacement is the number one reason they choose to steer clear of EVs, according to a 2025 survey from industry research firm AutoPacific. When early EVs hit the market, buyers' concerns were well-founded. Roughly one in 12 EVs built from 2011 to 2016 have had to have battery replacements. But new data shows that more modern EVs are doing better so far. Among EVs built from 2022 on, 0.3% have had battery replacements, according to a 2025 study from Recurrent. As battery technology has advanced, EVs have avoided problems like the ones that plagued the original Nissan Leaf when it hit the market in 2010, for example. Those cars lacked the battery-cooling technology that is in newer EVs, and they made headlines for wearing down quickly. Buyer perception hasn't quite caught up, according to Scott Case, co-founder and chief executive of Recurrent... The newest battery-powered EVs have lifespans comparable to internal-combustion-engine vehicles, even when driven more miles, according to Viet Nguyen-Tien, a research officer at the London School of Economics who focuses on Evs. Improvements in car batteries' chemical contents, battery-management systems and thermal regulation have been the difference in making batteries last longer and cost less, Nguyen-Tien said. Battery prices have fallen more than 90% since 2010, according to a BloombergNEF report from late last year. Industry analysts say battery-replacement costs are also improving as more EVs are designed for repairability in the long-haul. An out-of-warranty battery replacement can cost anywhere from $5,000 to $16,000, depending on the manufacturer, according to Recurrent. But many EV manufacturers have shifted to allow smaller components of their battery packs to be repaired, which can allow owners to avoid the full costs of a battery replacement, Case said. EV batteries aren't without their challenges, though. A battery that is frequently fast-charged with high power loses its range, on average, at twice the rate of a battery charged at a lower power, according to telematics company Geotab. Frequently charging a battery to 100%, or letting it rest at 0% for extended periods, can also reduce range long-term. And EVs regularly deliver less range in extreme cold or heat. The article also includes two new projections on EV adoption: "The share of new EVs sold is expected to nearly double to 11% of new-car sales in the U.S. by 2030, according to industry consulting firm AlixPartners." "Globally, EVs already make up 15% of new-car sales and are expected to form nearly a quarter of the global market by 2030, according to AlixPartners." Read more of this story at Slashdot.

  • Hobbit-like Humans May Have Scavenged Komodo Dragons' Leftovers to Survive
    by EditorDavid on 05/07/2026 at 8:34 am

    CNN reports: Prehistoric human relatives, nicknamed "hobbits" due to their short stature, may have been scavengers, rather than skilled hunters capable of taking down big game or building cooking fires, according to new research. The study adds to growing evidence that Homo floresiensis, which had a brain only slightly bigger than that of a chimpanzee, wasn't as advanced as scientists previously believed.... The researchers believe that much like how Komodo dragons hunt water buffaloes today, they were using their venomous bite to take down Stegodons — and after the scene was clear, Homo floresiensis swept in to cleave meat from what remained... The new study reinforces a long-held suspicion that Homo floresiensis is not a dwarfed form of Homo erectus but a descendant of a more primitive Homo habilis-like or Australopithecus-like form that arrived on the island more than1 million years ago, said Dr. Chris Stringer, a research leader specializing in human origins and paleoanthropology at London's Natural History Museum.

  • New Google Ad Imagines America's 'Declaration of Independence' Written With AI Help
    by EditorDavid on 05/07/2026 at 4:34 am

    An anonymous reader shared this report from TechCrunch: Two hundred and fifty years after the signing of the Declaration of Independence, a new commercial from Google asks: What if the Founding Fathers had access to Google Workspace? With the tagline "Group project, but make it 1776," the ad depicts a largely unseen Thomas Jefferson mid-draft when he gets a nagging text from Ben Franklin, leading to a very Google-centric collaboration process. Edits are suggested in Google Docs, a meeting gets scheduled in Google Calendar and conducted remotely via Google Meet (with every single attendee apparently turning their camera off?), then the whole thing is finalized with e-signatures; cue the fireworks. Of course, since this is an ad from a tech company in the year 2026, AI has a role to play. The fictionalized founders use Google's "help me visualize" AI tool to try out different animals on the national seal, Gemini takes notes on the meeting, and the founders also ask the chatbot for advice before declining King George III's document access request. TechCrunch call it "very tongue-in-cheek," noting that at one point Samuel Adams even asks, "Can we settle this over beers?" And they argue that "the AI evangelism is relatively discreet when compared to many other recent ads." Read more of this story at Slashdot.
