  • Thousands of Vibe-Coded Apps Expose Corporate and Personal Data On the Open Web
    by BeauHD on 08/05/2026 at 8:00 pm

    An anonymous reader quotes a report from Wired: Security researcher Dor Zvi and his team at the cybersecurity firm he cofounded, RedAccess, analyzed thousands of vibe-coded web applications created using the AI software development tools Lovable, Replit, Base44, and Netlify and found more than 5,000 of them that had virtually no security or authentication of any kind. Many of these web apps allowed anyone who merely finds their web URL to access the apps and their data. Others had only trivial barriers to that access, such as requiring that a visitor sign in with any email address. Around 40 percent of the apps exposed sensitive data, Zvi says, including medical information, financial data, corporate presentations, and strategy documents, as well as detailed logs of customer conversations with chatbots. "The end result is that organizations are actually leaking private data through vibe-coding applications," says Zvi. "This is one of the biggest events ever where people are exposing corporate or other sensitive information to anyone in the world." Zvi says RedAccess' scouring for vulnerable web apps was surprisingly easy. Lovable, Replit, Base44, and Netlify all allow users to host their web apps on those AI companies' own domains, rather than the users'. So the researchers used straightforward Google and Bing searches for those AI companies' domains combined with other search terms to identify thousands of apps that had been vibe coded with the companies' tools. Of the 5,000 AI-coded apps that Zvi says were left publicly accessible to anyone who simply typed their URLs into a browser, he found close to 2,000 that, upon closer inspection, seemed to reveal private data: Screenshots of web apps he shared with WIRED -- several of which WIRED verified were still online and exposed -- showed what appeared to be a hospital's work assignments with the personally identifiable information of doctors, a company's detailed ad purchasing information, what appeared to be another firm's go-to-market strategy presentation, a retailer's full logs of its chatbot's conversations with customers, including the customers' full names and contact information, a shipping firm's cargo records, and assorted sales and financial records from a variety of other companies. In some cases, Zvi says, he found that the exposed apps would have allowed him to gain administrative privileges over systems and even remove other administrators. In the case of Lovable, Zvi says he also found numerous examples of phishing sites that impersonated major corporations, including Bank of America, Costco, FedEx, Trader Joe's, and McDonald's, that appeared to have been created with the AI coding tool and hosted on Lovable's domain. "Anyone from your company at any moment can generate an app, and this is not going through any development cycle or any security check," Zvi says. "People can just start using it in production without asking anyone. And they do." Read more of this story at Slashdot.

  • Pentagon Begins Releasing New Files On UFOs
    by BeauHD on 08/05/2026 at 7:00 pm

    The Pentagon has begun releasing new UFO/UAP files through a newly launched public website, starting with 162 documents from agencies including the FBI, State Department, NASA, and others. Officials say more files will be released on a rolling basis. The Associated Press reports: The Pentagon has begun releasing new files on UFOs, saying members of the public can draw their own conclusions on "unidentified anomalous phenomena" like an object that a drone pilot says shone a bright light in the sky and then vanished. It said in a post on X on Friday that while past administrations sought to discredit or dissuade the American people, President Donald Trump "is focused on providing maximum transparency to the public, who can ultimately make up their own minds about the information contained in these files." It said additional documents will be released on a rolling basis. Besides the Pentagon, the effort is led by the White House, the director of national intelligence, the Energy Department, NASA and the FBI. A newly unveiled website housing the documents on unidentified anomalous phenomena, or UAPs, has a decidedly retro feel, with black-and-white military imagery of flying objects displayed prominently on the page, with statements displayed in typewriter-like font. The first release includes 162 files, such as old State Department cables, FBI documents and transcripts from NASA of crewed flights into space. One document details an FBI interview with someone identified as a drone pilot who, in September 2023, reported seeing a "linear object" with a light bright enough to "see bands within the light" in the sky. "The object was visible for five to ten seconds and then the light went out and the object vanished," according to the FBI interview. Another file is a NASA photograph from the Apollo 17 mission in 1972, showing three dots in a triangular formation. The Pentagon says in an accompanying caption that "there is no consensus about the nature of the anomaly" but that a new, preliminary analysis indicated that it could be a "physical object."

  • Apple, Intel Have Reached Preliminary Chip-Making Agreement
    by BeauHD on 08/05/2026 at 6:00 pm

    Apple and Intel have reportedly reached a preliminary agreement (paywalled; alternative source) for Intel to manufacture some chips used in Apple devices, after more than a year of talks and pressure from the Trump administration. It's still unclear which Apple products would use Intel-made chips, but the deal would mark a major potential win for Intel's foundry ambitions and give Apple another manufacturing option beyond TSMC.

  • AI Hard Drive Shortage Makes Archiving the Internet Harder
    by BeauHD on 08/05/2026 at 5:00 pm

    An anonymous reader quotes a report from 404 Media: Skyrocketing hard drive and storage costs caused by the AI data center boom are making it more expensive and more difficult for digital archivists, academics, Wikipedia, and hobby data hoarders to save data and archive the internet. Specific drives favored by some high profile organizations like the Internet Archive have become far more expensive or are difficult to find at all, archivists said. Over the last several months, prices for both consumer level and enterprise solid state drives, hard drives, and other types of storage have skyrocketed. As an example, a 2TB external Samsung SSD I purchased last fall for $159 now costs $575. PC Part Picker, a website that tracks the average price of different types of drives, shows a universal increase in storage prices starting in about October of last year. Prices of many of the drives it tracks have doubled or increased by more than 150 percent, and at some stores SSDs and hard drives are simply sold out. There is now even a secondary market for some SSDs, with people scalping them on eBay and elsewhere. Brewster Kahle, founder of the Internet Archive and the Wayback Machine, the most important archiving projects in the history of the internet, told 404 Media that the skyrocketing costs of storage is "a very real issue costing us time and money." "We have found that the preferred 28-30TB drives are just not available or at very high price," Kahle said. "We gather over 100 terabytes of new materials each day, and we have over 210 Petabytes of materials already archived on machines that need continuous upgrades and maintenance, so we need to constantly get new hard drives." "We are fortunate to have an active community that donates to the Archive, and we are also looking for help from hard drive manufacturers in these difficult times. We are always looking for more help," he added. "So far we have ways to work around these shortages, but it is a very real issue causing us time and money." The Wikimedia Foundation, which runs Wikipedia and various other projects, including Wikimedia Commons, an open repository of royalty free media, told 404 Media that the cost of storage has become a concern for the foundation's projects as well. "With over 65 million articles on Wikipedia alone, access to server and storage capacity is vital to us. We've certainly seen price increases since the end of 2025. These price increases are of concern to us, as with every other player in the industry. We see the primary impact in the purchase of memory and hard drives but also in terms of lead times on server deliveries and our capacity to place future orders," a Wikimedia Foundation spokesperson told us. "The Wikimedia Foundation is a non-profit, and as such how we allocate budget is very carefully considered. We maintain our own data centers to serve our users from all over the world. We're putting workarounds in place where we can, mainly involving being smart with how we prioritize investment in hardware, building in flexibility as well as extending the life of existing hardware where possible." Western Digital, one of the largest manufacturers of hard drives and other storage systems, said that it has essentially sold out of its 2026 inventory to enterprise clients, many of which run data centers. Micron, which made RAM and SSDs under the brand name Crucial, has exited the consumer market altogether because "AI-driven growth in the data center has led to a surge in demand for memory and storage. Micron has made the difficult decision to exit the Crucial consumer business in order to improve supply and support for our larger, strategic customers in faster-growing segments."

  • Chrome Silently Installs a 4GB AI Model On Your Device Without Consent
    by BeauHD on 08/05/2026 at 4:00 pm

    Longtime Slashdot reader couchslug shares a report from That Privacy Guy's Alexander Hanff: Two weeks ago I wrote about Anthropic silently registering a Native Messaging bridge in seven Chromium-based browsers on every machine where Claude Desktop was installed. The pattern was: install on user launch of product A, write configuration into the user's installs of products B, C, D, E, F, G, H without asking. Reach across vendor trust boundaries. No consent dialog. No opt-out UI. Re-installs itself if the user removes it manually, every time Claude Desktop is launched. This week I discovered the same pattern, executed by Google. Google Chrome is reaching into users' machines and writing a 4GB on-device AI model file to disk without asking. The file is named weights.bin. It lives in OptGuideOnDeviceModel. It is the weights for Gemini Nano, Google's on-device LLM. Chrome did not ask. Chrome does not surface it. If the user deletes it, Chrome re-downloads it. The legal analysis is the same one I gave for the Anthropic case. The environmental analysis is new. At Chrome's scale, the climate bill for one model push, paid in atmospheric CO2 by the entire planet, is between six thousand and sixty thousand tons of CO2-equivalent emissions, depending on how many devices receive the push. That is the environmental cost of one company unilaterally deciding that two billion peoples' default browser will mass-distribute a 4GB binary they did not request.

  • Cloudflare To Cut About 20% Workforce As AI Adoption Reshapes Operations
    by BeauHD on 08/05/2026 at 3:00 pm

    Cloudflare plans to cut about 20% of its workforce, or more than 1,100 employees, as it restructures around an "agentic AI-first operating model." Reuters reports: Cloudflare CEO Matthew Prince and co-founder Michelle Zatlyn said in a message to employees that the company was reimagining every team and function to operate in what they described as an agentic AI era. Cloudflare said the job cuts reflect a redesign of internal processes and roles, rather than a response to employee performance or short-term cost pressures. The company added that its own use of AI has increased more than sixfold over the past three months, prompting major changes in how teams operate. Read more of this story at Slashdot.
