Microsoft warns Windows users: expect more security updates as AI finds more bugs

Published

Windows security updates

Microsoft is about to ship more Windows security updates — and it wants you to know that’s a good thing

On July 9, the company published a blog post explaining that its use of artificial intelligence to hunt for zero-day vulnerabilities is about to bear more fruit. Literally. The fruit is patches.

“As AI helps defenders discover more issues, customers will see a higher volume of security updates included in each security release,” Microsoft wrote. The message is clear: get ready for a bigger pile of fixes every Patch Tuesday.

The company frames this as evidence that defenders are getting better at finding and fixing problems before attackers can weaponise them. “Our focus is to effectively utilize these AI tools to support faster protection, stronger engineering systems and more actionable guidance for customers,” it added.

What is MDASH and how does it work?

The key technical change inside Microsoft is a system called MDASH — short for multi-model agentic scanning harness. It’s not a single AI model but a coordinated team of several models working together to find novel vulnerabilities across the Windows codebase.

Here’s how Microsoft describes the pipeline:

  • A scanner pipeline runs across critical binaries and uses “multi-model debate” — different AI models argue over candidate vulnerabilities to validate them.
  • Confirmed candidates move to a separate “prove pipeline” that filters out remaining false positives.
  • Only the highest-confidence findings reach the engineering team.

Microsoft says this automation allows it to handle a larger volume of potential vulnerabilities and shortens the review window for new ones. The goal is to shrink the attack window for zero-day exploits — the most dangerous kind, because no patch exists when they’re discovered.

To run MDASH at Windows scale, the company set up dedicated cloud infrastructure for scanning and proving. That’s a significant investment, and it signals that Microsoft sees AI-driven vulnerability hunting as a long-term strategy rather than an experiment.

AI also changes Microsoft’s Secure Development Lifecycle

Microsoft is updating its Secure Development Lifecycle (SDL) best practices to account for what it calls “AI-enabled attack techniques and exploit paths.” That’s a recognition that attackers are also using AI to find holes in Windows, and the defense side needs to keep pace.

The company was careful to note that humans still sit at the top of the approval chain. No matter how many AI models debate a candidate vulnerability, a person makes the final call on whether to ship a patch. Quality control remains paramount.

The human element matters

Microsoft’s insistence on human oversight might sound like standard PR, but it reflects a real tension in the industry. A Cobalt study from June found that the percentage of organisations relying entirely on AI automation for vulnerability scanning dropped from 29% to 9% between 2025 and 2026. Over three-quarters of respondents said fully automated scanning tools missed critical vulnerabilities.

So while AI can scale vulnerability discovery, it still needs a human to separate real threats from noise. Microsoft’s prove pipeline and engineering review are designed to do exactly that — but the volume of incoming candidates will only grow.

Government agencies are also betting on AI for security

Microsoft isn’t the only big player pushing AI into vulnerability research. This week it emerged that the US Cybersecurity and Infrastructure Security Agency (CISA) is reportedly using Anthropic’s Claude model to scan for vulnerabilities across government systems.

In April, CISA’s Lindsey Cerkovnik, who represents the agency on the CVE Board, called on frontier AI companies to play a bigger role in software vulnerability disclosures. The message from Washington is consistent: AI tools should help defenders find bugs faster, and the results should be shared broadly.

The UK government has also been active in this space. It recently ran AI hackathons that uncovered over 400 vulnerabilities, suggesting that the technique works across different codebases and organisational contexts.

But AI is also part of the problem

For all the optimism, the same technology that helps defenders find bugs can also introduce new ones. A study from Orca Security published on July 9 claimed that 81% of organisations run vulnerable AI packages, and 99.9% of fixable AI vulnerabilities remain unpatched.

That’s a staggering number. It means almost every organisation using AI tools has known, fixable security holes in their AI stack — and almost nobody is applying the patches. The irony is hard to miss: AI helps find Windows vulnerabilities faster, but the AI tools themselves are a growing attack surface that most organisations ignore.

For IT teams, the takeaway is twofold. First, expect more Windows security updates coming your way, and plan your patch windows accordingly. Second, don’t assume your AI tools are secure just because they’re helping you find other people’s bugs. Patch your AI stack too.

What this means for IT administrators

The practical impact for anyone managing Windows environments is simple but significant: Patch Tuesday is going to get heavier. More updates means more testing, more reboots, and more chances for something to break.

Microsoft’s argument is that this is the price of better security. Fewer zero-days reaching attackers means fewer emergency out-of-band patches and fewer headlines about massive breaches. But the trade-off is a steady increase in the routine patching workload.

IT teams should review their patch management processes now. Automation tools that handle deployment and rollback will become more important. So will clear communication with end users about why updates are coming more frequently.

Microsoft’s MDASH system is still relatively new, and the full impact on update volume won’t be clear for several release cycles. But the direction is unmistakable: AI is going to find more bugs, and those bugs are going to become patches. The only question is how well organisations prepare for the surge.

G7 Tells the World to Speed Up the Quantum-Safe Encryption Transition

Published

quantum-safe encryption transition

Quantum Risk Is No Longer a Distant Worry

For years, the threat of quantum computers breaking today’s encryption felt like a problem for the next generation. The G7 just declared that mindset obsolete.

On September 3, under France’s 2026 G7 Presidency, the French National Cybersecurity Agency (ANSSI) — which chairs the G7 Cybersecurity Working Group — published a new call to action. It pushes governments and private organizations to start the quantum-safe encryption transition now, not later.

The document is blunt: reframe the quantum threat from “a distant future problem” to “a near-term threat that demands action across all sectors, not just critical infrastructure.”

Why the Sudden Urgency?

Quantum computers capable of breaking RSA and ECC — the very backbone of public-key cryptography — aren’t here yet. But the G7 notes that “several recent advances suggest an anticipation” of such machines. The exact timeline is uncertain, which is precisely the problem.

Attackers can already harvest encrypted data today and decrypt it later, once quantum machines mature. That’s the “harvest now, decrypt later” scenario that keeps security experts up at night. Waiting for proof that a working quantum computer exists would be a catastrophic mistake.

What the G7 Wants Organizations to Do

The call to action isn’t just a warning. It lays out a practical roadmap for the PQC migration.

First, identify the systems holding your most critical data. Prioritize those for the transition. Then inventory all cryptographic assets, map dependencies, and build a phased, risk-based plan.

The G7 also has a cost-saving tip: integrate post-quantum cryptography (PQC) into products you’re already buying. Replace systems as part of your standard renewal schedule rather than doing emergency rip-and-replace later. Starting early, the document argues, means lower migration costs overall.

Five Priorities for Governments and Industry

The G7 document outlines five concrete priorities that need attention from policymakers and the private sector:

  • Raise awareness about quantum threats across all sectors.
  • Develop national PQC strategies, including building an adequate supply of quantum-safe hardware and software.
  • Focus R&D on advancing PQC through practical innovation.
  • Build public-private partnerships between government, industry, and academia to grow domestic expertise.
  • Integrate PQC into cybersecurity requirements and procurement standards.

The document was signed by the national cybersecurity agencies of all G7 members — Canada, France, Germany, Italy, Japan, the UK, and the US — with support from the EU Commission and the EU Agency for Cybersecurity (ENISA).

ANSSI Is Already Moving the Goalposts

This isn’t ANSSI’s first warning shot. Months earlier, the agency announced it would stop vetting products that lack quantum-safe encryption starting in 2027. By 2030, post-quantum security becomes mandatory in procurement for certain security products in France.

That’s a hard deadline. If you sell security products into the French market, the clock is ticking. The G7 call to action suggests other member states may follow suit with similar requirements.

What This Means for Your Security Roadmap

If you haven’t started planning for the quantum-safe encryption transition, this document is your cue. The conversation has shifted from “if” to “when,” and from “someday” to “now.”

Start by taking inventory. You can’t protect what you don’t know you have. Map your cryptographic dependencies, identify crown-jewel data, and begin conversations with vendors about their PQC roadmaps. Many cybersecurity vendors are already preparing for the migration — make sure yours is one of them.

The quantum threat isn’t science fiction anymore. The G7 just made that official. Will your organization be ready when the deadline hits?

OpenAI Puts $1 Billion on the Table to Arm Critical Services with AI Defenses

OpenAI cybersecurity pledge

A Billion-Dollar Bet on the Little Guys

OpenAI has committed a staggering $1 billion to put its cutting-edge AI cybersecurity tools into the hands of those who need them most: the people keeping your lights on and your water running. The announcement, made on September 3, outlines a plan to subsidize access to its Daybreak AI models for essential services across the United States and, eventually, the globe.

It’s a direct response to a grim reality. Small municipalities, rural utilities, and local non-profits are getting hammered by sophisticated cyberattacks, yet they often lack the budget and specialized staff to fight back effectively. They are defending aging infrastructure with outdated tools against adversaries who move at machine speed.

This isn’t charity; it’s a strategic move to level a playing field that has grown dangerously tilted.

What Exactly is Daybreak?

For the uninitiated, Daybreak is OpenAI’s dedicated cybersecurity initiative, first unveiled back in May 2026. It’s not a single product but a suite of capabilities that leverages the company’s frontier large language models (LLMs) alongside its AI-coding assistant, Codex. These tools are designed to be deployed by approved defenders for a wide range of security tasks.

By August, OpenAI had evolved this into a two-tier system: Daybreak Red and Daybreak Blue. Red focuses on offensive security—hunting for vulnerabilities before the bad guys find them. Blue is about defense, helping teams monitor, analyze, and respond to threats in real time.

The New ‘Frontline Defenders’ Program

The new initiative, dubbed Daybreak for Frontline Defenders, is all about integration. OpenAI isn’t just handing out API keys. The program is designed to help critical sectors actually embed these AI models into their existing cybersecurity tools, services, and daily workflows. The goal is to make AI assistance as routine as a firewall update.

Which sectors are first in line? Think water treatment plants, electricity grids, local government networks, non-profits, and banking institutions. The rollout starts in the US, but OpenAI explicitly states it intends to expand to partner countries in the coming weeks.

The potential impact is huge. With Daybreak access, a two-person IT team at a rural water authority could review legacy code for flaws, analyze suspicious network activity, and even develop and test fixes—tasks that would typically require a team of expensive security engineers.

A Pilot with MS-ISAC: Putting Words into Action

Talk is cheap, so OpenAI is pairing the pledge with a concrete pilot. They’ve announced a collaboration with the Multi-State Information Sharing and Analysis Center (MS-ISAC). This pilot will pair Daybreak access with guided training and hands-on assistance for an initial group of public sector and water system defenders.

MS-ISAC is a critical piece of the US cyber defense puzzle. It provides threat intelligence, incident-response support, and real-time information sharing to thousands of public-sector organizations. The plan is to start small, develop a repeatable approach, and then expand the partnership over time. It’s a sensible, methodical start.

The Stark Warning That Preceded the Check

This $1 billion pledge didn’t happen in a vacuum. It landed exactly one week after a coalition of over 100 tech and cybersecurity companies—OpenAI included—published an open letter on August 27. That letter was a blunt instrument, warning of a “narrowing window” to act before AI-enabled attacks escalate to a level that puts critical public services at severe risk.

The message was clear: the same AI that powers defensive tools also supercharges attackers. If we don’t democratize access to frontier AI for defenders, we’re essentially handing the keys to the kingdom to cybercriminals.

OpenAI echoed this sentiment in its announcement, stating that the defender’s window “will not stay open indefinitely.” The opportunity, they argue, is to ensure the advantages of frontier AI extend beyond the largest companies and best-resourced security teams, reaching into the communities and institutions whose security affects millions of people.

Beyond this pledge, OpenAI is also working on what it calls a Defense Factory—an automated approach designed to continuously discover, validate, and fix vulnerabilities. It’s part of a broader push to make AI-driven security proactive rather than reactive.

For anyone tracking the intersection of AI and national security, this is a significant development. The question isn’t whether AI will play a role in defending critical infrastructure—that’s a given. The real question is whether the defenders of that infrastructure will have equal access to the tools. With this billion-dollar bet, OpenAI is trying to make sure they do.

US and UK Join Forces to Dismantle Scam Centers Behind Billions in Fraud

Published

scam center takedowns

A New Alliance Against Cyber Fraud

The United States and the United Kingdom are pooling resources to shut down the sprawling scam centers that have siphoned billions from victims worldwide. A memorandum of understanding signed Thursday commits both nations to parallel investigations and shared intelligence on the organized crime networks behind these operations, many of which are based in Southeast Asia.

U.S. Attorney Jeanine Ferris Pirro met with senior officials from the U.K.’s National Crime Agency and Crown Prosecutor to formalize the agreement. Pirro stated the objective is to “disable” the Chinese gangs that operate these compounds.

How the Partnership Will Work

The memorandum outlines a framework for both countries to identify overlapping cases and decide which jurisdictions will bring charges. The goal is to prioritize cases that can deliver significant mutual impact.

Officials from both sides had already flagged substantial case overlaps. They are now committed to a joint disruption event with private industry partners, scheduled for early October in London and hosted by the National Crime Agency.

The Scam Center Strike Force Takes the Lead

This initiative is spearheaded by the Scam Center Strike Force, launched last November to coordinate U.S. enforcement against cyber-enabled fraud. The numbers are staggering: the FBI reports that cyber-enabled fraud accounts for nearly 85% of all losses reported to the agency. Americans lost over $12 billion to these scams last year — a figure likely far below reality, as many victims never come forward.

Assistant U.S. Attorney Karen Seifert leads the Strike Force. Testifying before Congress in March, she noted the team includes more than 150 personnel, drawing on prosecutors and agents from the FBI, IRS, and U.S. Postal Inspection Service.

Human Trafficking at the Core

These scam centers are not merely criminal enterprises; they are built on human trafficking. Victims are held in compounds across Myanmar, Cambodia, Laos, and neighboring countries, forced to run investment and romance fraud schemes. Chinese syndicates control the operations, often with the complicity of compromised local officials.

Early Wins and the Road Ahead

The Strike Force has already claimed a major victory. The disruption of Prince Group, a Chinese front company used to launder illicit proceeds, led to sanctions from both U.S. and U.K. agencies. The Justice Department also seized roughly $15 billion in bitcoin tied to the company’s CEO, Chen Zhi.

That seizure sent a clear message. But the problem is vast, and the syndicates are adaptive. The new US-UK partnership signals a recognition that no single nation can tackle this threat alone.
