  • Hackers Targeted Municipal Water Systems In 7 States This Week, FBI Says
    by BeauHD on 31/07/2026 at 8:10 pm

    An anonymous reader quotes a report from NBC News: Cyberattacks targeting municipal water systems have been reported in at least seven states this week, prompting the FBI and the Environmental Protection Agency to warn utilities nationwide that hackers are trying to disrupt critical water infrastructure. In a public service announcement Thursday, the agencies said water and wastewater utilities have reported incidents to the FBI, with some malicious activity degrading water operations. The announcement does not name the states. The warning comes after hackers targeted more than 30 municipal water facilities in Minnesota in an attack that had hallmarks of Iranian meddling, according to a law enforcement official. It is still under investigation. A spokesperson for Minnesota's information technology services agency said Thursday there was no indication the breaches contaminated any municipal water supplies. The federal Cybersecurity and Infrastructure Security Agency said in a separate alert that some larger attacks on water infrastructure had "resulted in boil water notices and sustained manual operations," though it did not say where. [...] The federal advisory said the malicious cyber actors, or MCAs, targeted specific brands of control systems used by municipal water utilities, though the FBI and the EPA urged operators of all systems to take precautions. [...] The agencies said the hackers remotely accessed internet-facing devices, changed IP addresses and passwords, and caused utilities to lose monitoring and control capabilities. The federal advisory calls on system operators to remove programmable logical controllers, or PLCs, from direct internet exposure by putting them behind secure gateways and firewalls; use strong passwords; and limit communications between authorized control system devices through access control lists.

  • New Google Earth AI Tool Could Fuel Misinformation, Experts Say
    by BeauHD on 31/07/2026 at 7:00 pm

    Google has integrated its Nano Banana 2 image generator into Google Earth, allowing users to place AI-generated events and objects onto real satellite imagery. The company says its AI-generated images contain invisible watermarks detectable through Gemini or Lens, but the BBC found those safeguards and some third-party detection tools can be fooled into labeling manipulated Google Earth images as real. From the report: A collapsed Eiffel Tower, a sinkhole swallowing the Great Pyramid of Giza and Russian tanks in Ukraine's capital were among the images BBC Verify was able to create when testing the feature, which was rolled out on Thursday. Google has not yet responded to questions based on BBC Verify's tests, but in a social media post the company said they "take misinformation seriously" and that "we prevent image creation on harmful topics and are continually updating our protections." AI and misinformation expert Henk van Ess has highlighted the risks this feature poses, creating fake images of a non-existent nuclear power plant in Iran, a refugee camp on the US-Mexico border and a fake hospital in Gaza with a bomb crater next to it. He said Google was allowing "invented" imagery to be "welded to genuine coordinates, drawn on genuine imagery." "The forgery does not have to look convincing on its own. It inherits the credibility of the map it was born on," van Ess added. UPDATE 7/31/26 10:54 AM: Google is rolling back the image generation inside of Google Earth: "We know that people uniquely trust Google Earth for a reliable view of the world. We've seen geospatial professionals using this feature for a range of useful purposes, however we've also seen people sharing screenshots of generated imagery that appear to violate our policies. So we're rolling back this feature in Google Earth while we work on implementing stronger guardrails. It's important to note that generated images didn't appear in the main Google Earth experience for others to see and were watermarked as AI generated." Read more of this story at Slashdot.

  • Publishers Are Losing Google Traffic As AI Answers Replace Links
    by BeauHD on 31/07/2026 at 6:00 pm

    alternative_right shares a report from Axios: Google has basically stopped sending people to websites (including our site) for answers and information. Instead, it's using AI to answer them on its platform, in its words. Chartbeat data shared with Axios shows Google Search traffic to publishers fell 34% over the past year. That pain is regressive. Over the past two years, small publishers lost 60% of referrals from search overall, medium publishers 47%, large publishers 22%. Read more of this story at Slashdot.

  • New York Sues Kalshi For Running 'Illegal Gambling Operation'
    by BeauHD on 31/07/2026 at 5:00 pm

    New York has sued prediction-market platform Kalshi, alleging it operates an "illegal gambling operation" without state authorization. "No matter what they call themselves, prediction markets like Kalshi are gambling platforms, plain and simple," said New York Attorney General Letitia James in a press release announcing the lawsuit. "By ignoring our laws, Kalshi is running an illegal operation and harming New Yorkers in the process." CNBC reports: In a case filed in a Manhattan state court (PDF), the lawsuit claims that Kalshi accepts wagers as a gambling business in disregard for the state's constitution and laws by not being registered with the New York State Gaming Commission. Governor Kathy Hochul in the press release said the state is taking the action to stop what it views as illegal behavior and bring the company into compliance with New York law. The lawsuit is seeking a permanent injunction against Kalshi. The suit by the state is also seeking a total restitution to users who have placed trades on the platform, a $100,000 penalty for each attempt to offer sports wagering, and another penalty three times the amount the company has gained while allegedly operating in violation of New York law. The state estimates that could total $36 billion. Read more of this story at Slashdot.

  • Chrome Is Using AI To Fix Hundreds of Bugs, Eliminate Full Browser Restarts
    by BeauHD on 31/07/2026 at 4:00 pm

    Google says AI-assisted workflows helped Chrome fix 1,072 security bugs across versions 149 and 150, more than the previous 23 releases combined. The company is also testing twice-weekly security updates and "dynamic patching," which could apply most fixes without requiring users to restart the entire browser. "By leveraging Chrome's multi-process architecture, dynamic patching sequentially replaces background child processes (like the Renderer and GPU) with updated binaries on the fly," says Google in a blog post. PiunikaWeb reports: Alongside dynamic patching, Google is rolling out smarter background updates during periods of minimal user disruption. Starting with Chrome 150 on macOS, the browser takes advantage of the operating system's windowless state. If all Chrome windows are closed but the app remains running in the background, the browser will quietly auto-restart to apply pending updates. For enterprise environments, IT admins can continue to manage fleet-wide deployments through Chrome Enterprise Core or enforce update prompts using the RelaunchNotification policy. Google's long-term vision is a browser that remains continuously protected in the background without interrupting your daily browsing session. In the meantime, you can manually trigger pending updates by clicking the update prompt in the top-right corner of Chrome. Read more of this story at Slashdot.

  • LinkedIn Introduces a 'Seems Like AI Slop' Button
    by BeauHD on 31/07/2026 at 1:00 pm

    An anonymous reader quotes a report from 404 Media: LinkedIn, a social network awash with long AI-generated posts from executives and other corporate workers, has introduced a new button that users can click to flag if a post "seems like AI slop," according to 404 Media's own tests. If you have been anywhere near LinkedIn in the past couple of years, you have undoubtedly seen users posting blatantly AI-generated missives. Often these posts take some sort of news event, and opine on how this relates to thought leadership, or some other LinkedIn brainrot term. It's also pretty wild the button specifically uses the term "AI slop" and not, say, "It seems this was generated with AI." [...] After publication of this piece, Hari Srinivasan, chief product officer at LinkedIn, wrote their own post about the button. "AI slop is a top priority for all of us. We really care about this. People come to LinkedIn to connect with real people and share their real perspectives, ideas and expertise. Here are a few more changes to keep it that way," he wrote. The button in part will help LinkedIn tune its own models for identifying AI slop. "We are ramping up a series of new and improved classifiers that identify if a post is AI-slop or generally low-quality content. This will reduce the amount of AI slop you might see in suggested content and content from outside your network," the post said. "We are ramping the ability for members to tell us if they believe a post or comment seems like AI slop. Slop is hard to define and the definition changes; this lets us tune our models and make better feeds." Srinivasan also said LinkedIn is removing the AI-powered "enhance your post" feature with another that "proofreads your words, but does not change your voice." Read more of this story at Slashdot.
