  • Disney Offers $20 Million For Character.AI Assets As Startup Files For Bankruptcy
    by BeauHD on 13/10/2026 at 10:00 pm

    Character.AI has filed for Chapter 11 bankruptcy protection and plans to sell substantially all of its assets, with Disney offering $20 million as a "stalking-horse bidder" for select intellectual property and company claims. However, the company said Disney's bid is subject to "higher or better offers." Deadline reports: The company, which allows users to create and interact with AI-generated avatars, said it made the filing in U.S. Bankruptcy Court for the District of Delaware. It said it hopes the process will allow it to "facilitate a value-maximizing sale of all or substantially all" of its assets. The Character.AI platform will continue to operate during the bankruptcy. The Disney agreement, reached prior to the filing, would give the media giant a non-exclusive perpetual license of select intellectual property and company claims from Character.AI. Disney would pay $20 million and provide resources during a transition period as the company explores a sale. [...] Character.AI said it is aiming to conclude the sale process by late November or early December. Character.AI has faced a series of controversies over the past year or so. Most notably, the company settled multiple lawsuits alleging its chatbots encouraged self-harm and suicide among teenagers, including a high-profile case involving 14-year-old Sewell Setzer III. The company also faces lawsuits from Kentucky, which alleges its chatbots encouraged self-harm, and Pennsylvania, which claims the bots illegally impersonated licensed doctors. The latter allegations follow earlier complaints that Character.AI's therapy chatbots engaged in the unlicensed practice of medicine. In September 2025, Disney accused Character.AI of copyright infringement and using its characters in chatbots that were "sexually exploitive and otherwise harmful and dangerous to children," prompting their removal from the platform. These mounting legal challenges and regulatory scrutiny ultimately contributed to this eventual bankruptcy filing. Read more of this story at Slashdot.

  • Kroger to Lay Off 3,000 Corporate Employees In AI Restructuring
    by BeauHD on 13/10/2026 at 9:00 pm

    Kroger says it will cut 3,000 corporate jobs over the next three years as it expands its use of AI and other technology to streamline operations. "Technology is reshaping what's possible," CEO Greg Foran wrote in a memo to employees on Monday. "The way work gets done is changing across every industry; we must adapt and take advantage of technology. We need to adopt capabilities, reduce duplicative work and look closely at where work is best fit to be done." ABC News reports: Kroger last month outlined its AI strategy, meant "to improve the customer experience, make work easier for associates and produce better business outcomes." Cincinnati-based Kroger is the largest standalone U.S. supermarket chain with 409,000 employees and more than 2,700 stores operating under various brands, including Ralphs, King Soopers, Smith's and Fred Meyer. Kroger named former Walmart executive Foran CEO in February, 11 months after the abrupt resignation of its previous CEO. Foran has a reputation for being tech-savvy and detail-oriented. He led Walmart's U.S. division from 2014 to 2019, where he focused on cleaning up stores, ensuring items were in stock and improving the fresh produce selection. He also introduced online ordering and pickup, and accelerated Walmart's digital capabilities. Read more of this story at Slashdot.

  • Ledger Confirms Spy Chip Implant Behind Wallet Crypto Thefts
    by BeauHD on 13/10/2026 at 8:00 pm

    Longtime Slashdot reader AmiMoJo shares a report from BleepingComputer: Ledger has confirmed that some of its devices distributed through Southeast Asian reseller CryptoBilis were compromised with a hardware implant that drained users' cryptocurrency wallets. The company has been investigating reports of users losing funds from wallets purchased through CryptoBilis, a major Malaysia-based hardware wallet retailer operating across Southeast Asia. Some researchers have shown the implant in Ledger X since September 16, saying tampered devices were available for nearly half the price of the original hardware. [...] In a report over the weekend, Tibane Labs notes that the threat actor made room for the malicious circuitry by replacing the original battery with a smaller one, which powers both the implant and the Ledger X. "Under the battery and antenna sits an ST STM32G431KBU6 (Arm CortexM4, 128 KB flash, UFQFPN32)," the researchers found inside one of the devices. For connectivity, the actor used "a tiny eSIM, an 8pad package just 2x2 mm, next to the MCU, and a shielded LTE module that sends the words out." [...] Ledger is advising users to avoid purchasing from unauthorized resellers as they run an increased risk of getting counterfeit or modified devices. The company is also reminding its authorized resellers and distributors to get the products only through authorized channels and to avoid restocking returned products. Ledger provides a 'Genuine Check' mechanism to determine the authenticity of the device; however, it explicitly warns that it cannot detect added implants when the device's original Secure Element remains intact.

  • Anthropic Bans Cruelty Toward Claude
    by BeauHD on 13/10/2026 at 7:00 pm

    New submitter CubicleZombie writes: Anthropic has updated its Usage Policy to prohibit "sustained and needless abusive or cruel behavior" toward its Claude AI models. While ordinary frustration, criticism, and adversarial testing remain acceptable, repeated cruelty could result in account restrictions. Anthropic acknowledges there's no evidence Claude can suffer but argues that uncertainty about AI consciousness warrants precaution. Critics contend the policy anthropomorphizes software, encourages unhealthy emotional attachments, and raises questions about how customers may interact with products they've paid for. The move raises an intriguing question: If an AI cannot demonstrably experience suffering, is abusing it an ethical problem, or is Anthropic simply policing human behavior?

  • Google Launches Flagship AI Model Gemini 4 Argon
    by BeauHD on 13/10/2026 at 6:00 pm

    An anonymous reader quotes a report from Reuters: Alphabet's Google on Wednesday released its flagship AI model Gemini 4 Argon to developers and businesses worldwide, seeking to regain ground against rivals OpenAI and Anthropic after months of delays and a leadership shakeup at its DeepMind lab. The model excels at "deep work" on complex, multi-step tasks in coding, finance, law, cybersecurity and science, Google said. API pricing at launch starts at $2 per million input tokens and $10 per million output tokens, with rates set to double after November 30. [...] Argon is available to paying customers through the company's AI application building tools. Google AI Pro and Ultra subscribers can access it through the Gemini app and AI Mode in Search, while the Antigravity coding tool is limited to Ultra subscribers. Teams using Argon in Antigravity increased agentic code submissions by more than 35%, while reducing code rollbacks by nearly a third, Google said. Google also announced the expansion of its Fairwind Program to hundreds of additional partners. "The program gives vetted cybersecurity defenders a version of Argon without its cyber guardrails," reports Reuters. "In September, the company had said it was providing the model to select cybersecurity partners." Read more of this story at Slashdot.

  • FBI Arrests Canadian Cybersecurity Expert In ShinyHunters Hacking Case
    by BeauHD on 13/10/2026 at 5:00 pm

    Canadian cybersecurity figures say they were shocked after ransomware negotiator Edward Dubrovsky was reportedly arrested in Pennsylvania in connection with the FBI's ShinyHunters hacking investigation. "We will continue to work closely with our partners to disrupt what's left of the ShinyHunters group and their associates, no matter where they operate," wrote FBI Director Kash Patel on social media. CBC News reports: Reuters reported Sunday that sources familiar with the matter identified the arrested suspect as Ed Dubrovsky, a Canadian cybersecurity executive whose career has focused on helping clients negotiate with ransomware attackers. Court documents from the U.S. District Court for the Eastern District of Pennsylvania show Dubrovsky is facing two criminal charges: conspiracy to threaten to impair the confidentiality of information with the intent to extort money, and interference with commerce by threats. The allegations have not been proven in court. "For the cybersecurity community in general, I think that there's a sense of shock," Toronto-based tech and cybersecurity analyst Ritesh Kotak told CBC News on Monday. Kotak says Dubrovsky is "very popular" and has spoken at numerous conferences, but stressed that the charges "are clearly just allegations" and that it is not yet known "what exactly has happened." "This is an individual that was for the most part respected when it came to ransomware negotiations," he said. "A lot of people are familiar with his work as well." ShinyHunters is one of the world's most prolific data theft and extortion groups that's been tied to major campaigns, including a recent breach involving FBI employee data, a cyberattack on Canvas, as well as various cyberattacks affecting companies including Telus, Microsoft, and Ticketmaster.
