Microsoft and GitHub Preview New Tool That Identifies, Prioritizes, and Fixes Vulnerabilities With AI

Sun, 2025-11-23 16:34
"Security, development, and AI now move as one," says Microsoft's director of cloud/AI security product marketing. Microsoft and GitHub "have launched a native integration between Microsoft Defender for Cloud and GitHub Advanced Security that aims to address what one executive calls decades of accumulated security debt in enterprise codebases..." according to The New Stack: The integration, announced this week in San Francisco at the Microsoft Ignite 2025 conference and now available in public preview, connects runtime intelligence from production environments directly into developer workflows. The goal is to help organizations prioritize which vulnerabilities actually matter and use AI to fix them faster. "Throughout my career, I've seen vulnerability trends going up into the right. It didn't matter how good of a detection engine and how accurate our detection engine was, people just couldn't fix things fast enough," said Marcelo Oliveira, VP of product management at GitHub, who has spent nearly a decade in application security. "That basically resulted in decades of accumulation of security debt into enterprise code bases." According to industry data, critical and high-severity vulnerabilities constitute 17.4% of security backlogs, with a mean time to remediation of 116 days, said Andrew Flick, senior director of developer services, languages and tools at Microsoft, in a blog post. Meanwhile, applications face attacks as frequently as once every three minutes, Oliveira said. The integration represents the first native link between runtime intelligence and developer workflows, said Elif Algedik, director of product marketing for cloud and AI security at Microsoft, in a blog post... The problem, according to Flick, comes down to three challenges: security teams drowning in alert fatigue while AI rapidly introduces new threat vectors that they have little time to understand; developers lacking clear prioritization while remediation takes too long; and both teams relying on separate, nonintegrated tools that make collaboration slow and frustrating... The new integration works bidirectionally. When Defender for Cloud detects a vulnerability in a running workload, that runtime context flows into GitHub, showing developers whether the vulnerability is internet-facing, handling sensitive data or actually exposed in production. This is powered by what GitHub calls the Virtual Registry, which creates code-to-runtime mapping, Flick said... In the past, this alert would age in a dashboard while developers worked on unrelated fixes because they didn't know this was the critical one, he said. Now, a security campaign can be created in GitHub, filtering for runtime risk like internet exposure or sensitive data, notifying the developer to prioritize this issue. GitHub Copilot "now automatically checks dependencies, scans for first-party code vulnerabilities and catches hardcoded secrets before code reaches developers," the article points out — but GitHub's VP of product management says this takes things even further. "We're not only helping you fix existing vulnerabilities, we're also reducing the number of vulnerabilities that come into the system when the level of throughput of new code being created is increasing dramatically with all these agentic coding agent platforms."

Engineers are Building the Hottest Geothermal Power Plant on Earth - Next to a US Volcano

Sun, 2025-11-23 15:34
"On the slopes of an Oregon volcano, engineers are building the hottest geothermal power plant on Earth," reports the Washington Post: The plant will tap into the infernal energy of Newberry Volcano, "one of the largest and most hazardous active volcanoes in the United States," according to the U.S. Geological Survey. It has already reached temperatures of 629 degrees Fahrenheit, making it one of the hottest geothermal sites in the world, and next year it will start selling electricity to nearby homes and businesses. But the start-up behind the project, Mazama Energy, wants to crank the temperature even higher — north of 750 degrees — and become the first to make electricity from what industry insiders call "superhot rock." Enthusiasts say that could usher in a new era of geothermal power, transforming the always-on clean energy source from a minor player to a major force in the world's electricity systems. "Geothermal has been mostly inconsequential," said Vinod Khosla, a venture capitalist and one of Mazama Energy's biggest financial backers. "To do consequential geothermal that matters at the scale of tens or hundreds of gigawatts for the country, and many times that globally, you really need to solve these high temperatures." Today, geothermal produces less than 1 percent of the world's electricity. But tapping into superhot rock, along with other technological advances, could boost that share to 8 percent by 2050, according to the International Energy Agency (IEA). Geothermal using superhot temperatures could theoretically generate 150 times more electricity than the world uses, according to the IEA. "We believe this is the most direct path to driving down the cost of geothermal and making it possible across the globe," said Terra Rogers, program director for superhot rock geothermal at the Clean Air Task Force, an environmentalist think tank. "The [technological] gaps are within reason. These are engineering iterations, not breakthroughs." The Newberry Volcano project combines two big trends that could make geothermal energy cheaper and more widely available. First, Mazama Energy is bringing its own water to the volcano, using a method called "enhanced geothermal energy"... [O]ver the past few decades, pioneering projects have started to make energy from hot dry rocks by cracking the stone and pumping in water to make steam, borrowing fracking techniques developed by the oil and gas industry... The Newberry project also taps into hotter rock than any previous enhanced geothermal project. But even Newberry's 629 degrees fall short of the superhot threshold of 705 degrees or above. At that temperature, and under a lot of pressure, water becomes "supercritical" and starts acting like something between a liquid and a gas. Supercritical water holds lots of heat like a liquid, but it flows with the ease of a gas — combining the best of both worlds for generating electricity... [Sriram Vasantharajan, Mazama's CEO] said Mazama will dig new wells to reach temperatures above 750 degrees next year. Alongside an active volcano, the company expects to hit that temperature less than three miles beneath the surface. But elsewhere, geothermal developers might have to dig as deep as 12 miles. While Mazama plans to generate 15 megawatts of electricity next year, it hopes to eventually increase that to 200 megawatts. (And the company's CEO said it could theoretically generate five gigawatts of power.) But more importantly, successful projects "motivate other players to get into the market," according to a senior geothermal research analyst at energy consultancy Wood Mackenzie, who predicted "a ripple effect," to the Washington Post where "we'll start seeing more companies get the financial support to kick off their own pilots."

How the Internet Rewired Work - and What That Tells Us About AI's Likely Impact

Sun, 2025-11-23 12:34
"The internet did transform work — but not the way 1998 thought..." argues the Wall Street Journal. "The internet slipped inside almost every job and rewired how work got done." So while the number of single-task jobs like travel agent dropped, most jobs "are bundles of judgment, coordination and hands-on work," and instead the internet brought "the quiet transformation of nearly every job in the economy... Today, just 10% of workers make minimal use of the internet on the job — roles like butcher and carpet installer." [T]he bigger story has been additive. In 1998, few could conceive of social media — let alone 65,000 social-media managers — and 200,000 information-security analysts would have sounded absurd when data still lived on floppy disks... Marketing shifted from campaign bursts to always-on funnels and A/B testing. Clinics embedded e-prescribing and patient portals, reshaping front-office and clinical handoffs. The steps, owners and metrics shifted. Only then did the backbone scale: We went from server closets wedged next to the mop sink to data centers and cloud regions, from lone system administrators to fulfillment networks, cybersecurity and compliance. That is where many unexpected jobs appeared. Networked machines and web-enabled software quietly transformed back offices as much as our on-screen lives. Similarly, as e-commerce took off, internet-enabled logistics rewired planning roles — logisticians, transportation and distribution managers — and unlocked a surge in last-mile work. The build-out didn't just hire coders; it hired coordinators, pickers, packers and drivers. It spawned hundreds of thousands of warehouse and delivery jobs — the largest pockets of internet-driven job growth, and yet few had them on their 1998 bingo card... Today, the share of workers in professional and managerial occupations has more than doubled since the dawn of the digital era. So what does that tell us about AI? Our mental model often defaults to an industrial image — John Henry versus the steam drill — where jobs are one dominant task, and automation maps one-to-one: Automate the task, eliminate the job. The internet revealed a different reality: Modern roles are bundles. Technologies typically hit routine tasks first, then workflows, and only later reshape jobs, with second-order hiring around the backbone. That complexity is what made disruption slower and more subtle than anyone predicted. AI fits that pattern more than it breaks it... [LLMs] can draft briefs, summarize medical notes and answer queries. Those are tasks — important ones — but still parts of larger roles. They don't manage risk, hold accountability, reassure anxious clients or integrate messy context across teams. Expect a rebalanced division of labor: The technical layer gets faster and cheaper; the human layer shifts toward supervision, coordination, complex judgment, relationship work and exception handling. What to expect from AI, then, is messy, uneven reshuffling in stages. Some roles will contract sharply — and those contractions will affect real people. But many occupations will be rewired in quieter ways. Productivity gains will unlock new demand and create work that didn't exist, alongside a build-out around data, safety, compliance and infrastructure. AI is unprecedented; so was the internet. The real risk is timing: overestimating job losses, underestimating the long, quiet rewiring already under way, and overlooking the jobs created in the backbone. That was the internet's lesson. It's likely to be AI's as well.

Microsoft Warns Its Windows AI Feature Brings Data Theft and Malware Risks, and 'Occasionally May Hallucinate'

Sun, 2025-11-23 08:34
"Copilot Actions on Windows 11" is currently available in Insider builds (version 26220.7262) as part of Copilot Labs, according to a recent report, "and is off by default, requiring admin access to set it up." But maybe it's off for a good reason...besides the fact that it can access any apps installed on your system: In a support document, Microsoft admits that features like Copilot Actions introduce " novel security risks ." They warn about cross-prompt injection (XPIA), where malicious content in documents or UI elements can override the AI's instructions. The result? " Unintended actions like data exfiltration or malware installation ." Yeah, you read that right. Microsoft is shipping a feature that could be tricked into installing malware on your system. Microsoft's own warning hits hard: "We recommend that you only enable this feature if you understand the security implications." When you try to enable these experimental features, Windows shows you a warning dialog that you have to acknowledge. ["This feature is still being tested and may impact the performance or security of your device."] Even with these warnings, the level of access Copilot Actions demands is concerning. When you enable the feature, it gets read and write access to your Documents, Downloads, Desktop, Pictures, Videos, and Music folders... Microsoft says they are implementing safeguards. All actions are logged, users must approve data access requests, the feature operates in isolated workspaces, and the system uses audit logs to track activity. But you are still giving an AI system that can "hallucinate and produce unexpected outputs" (Microsoft's words, not mine) full access to your personal files. To address this, Ars Technica notes, Microsoft added this helpful warning to its support document this week. "As these capabilities are introduced, AI models still face functional limitations in terms of how they behave and occasionally may hallucinate and produce unexpected outputs." But Microsoft didn't describe "what actions they should take to prevent their devices from being compromised. I asked Microsoft to provide these details, and the company declined..."
