Microsoft MDASH is working on bugs that haven&#8217;t been found by any of the human teams.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Microsoft MDASH (Multi-Model Agentic Scanning Harness) is not a chatbot or a security copilot, but it was unveiled at Build 2026. It&#8217;s a closed AI pipeline that runs 100+ discrete agents to find, validate, and surface vulnerable issues in enterprise codebases and delivers its findings in Microsoft Defender. Before Build 2026, MDASH had found 16 previously unknown Windows security bugs, four of which were critical remote-code-execution problems. All the bugs were fixed in the May 2026 Patch Tuesday update.<\/p><div id=\"ez-toc-container\" class=\"ez-toc-v2_0_84 ez-toc-wrap-center counter-hierarchy ez-toc-counter ez-toc-light-blue ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #414141;color:#414141\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #414141;color:#414141\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/threatcop.com\/blog\/microsoft-mdash-ai-vulnerability-scanner\/#What_Is_Microsoft_MDASH\" >What Is Microsoft MDASH?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/threatcop.com\/blog\/microsoft-mdash-ai-vulnerability-scanner\/#Book_a_Free_Demo_Call_with_Our_Expert\" >Book a Free Demo Call with Our Expert<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/threatcop.com\/blog\/microsoft-mdash-ai-vulnerability-scanner\/#How_Does_Microsoft_MDASH_Work\" >How Does Microsoft MDASH Work?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/threatcop.com\/blog\/microsoft-mdash-ai-vulnerability-scanner\/#What_Has_MDASH_Found\" >What Has MDASH Found?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/threatcop.com\/blog\/microsoft-mdash-ai-vulnerability-scanner\/#What_Is_the_Relationship_Between_MDASH_Defender_and_GitHub\" >What Is the Relationship Between MDASH, Defender, and GitHub?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/threatcop.com\/blog\/microsoft-mdash-ai-vulnerability-scanner\/#What_This_Means_for_Enterprise_Security_Teams\" >What This Means for Enterprise Security Teams<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-7\" href=\"https:\/\/threatcop.com\/blog\/microsoft-mdash-ai-vulnerability-scanner\/#What_MDASH_Does_Not_Cover\" >What MDASH Does Not Cover<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-8\" href=\"https:\/\/threatcop.com\/blog\/microsoft-mdash-ai-vulnerability-scanner\/#Frequently_Asked_Questions\" >Frequently Asked Questions<\/a><\/li><\/ul><\/nav><\/div>\n\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Is_Microsoft_MDASH\"><\/span><strong>What Is Microsoft MDASH?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">MDASH from Microsoft is an AI-powered security bug discovery system that leverages more than 100 domain-specific agents in a 5-stage pipeline to find real, exploitable vulnerabilities in large codebases.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The word real is the one to focus on. Static analyzers are hardcoded rule sets. They cannot perform cross-file dataflow analysis, traverse execution paths, or determine whether a bug is truly exploitable. MDASH can do all three.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The system is the product, according to Taesoo Kim, VP of Microsoft&#8217;s Agentic Security division. MDASH was built by the Microsoft Autonomous Code Security team, many of whose developers came from Team Atlanta at Georgia Tech, which won the DARPA AI Cyber Challenge in 2024.<\/p>\n\n\n\n<meta charset=\"UTF-8\">\n  <meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\">\n  <title>Threatcop \u2013 Book a Free Demo<\/title>\n  <link href=\"https:\/\/fonts.googleapis.com\/css2?family=Outfit:wght@300;400;500;600;700&amp;display=swap\" rel=\"stylesheet\">\n  <style>\n    .tc-wrap *, .tc-wrap *::before, .tc-wrap *::after { box-sizing: border-box;

The system ingests source code, builds language-sensitive indexes, and maps the attack surface by analyzing commit history.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Stage 2:<\/strong> Scan. Auditor agents traverse candidate code paths and report their findings. Each finding includes a hypothesis and supporting evidence, not a pattern match.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Stage 3:<\/strong> Validate. Debater agents try to disprove each finding by testing whether the flaw is actually reachable. If they can&#8217;t shoot it down, the finding gains credibility. Disagreement is treated as a signal.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Stage 4:<\/strong> Dedup. When two or more semantically identical findings come up, they are grouped into a single report, making it easier for the analyst to review.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Stage 5:<\/strong> Prove. The system generates a working proof-of-concept that triggers the bug.<a href=\"https:\/\/github.com\/google\/sanitizers\/wiki\/AddressSanitizer\"> AddressSanitizer<\/a> is used to confirm it in the C and C++ world. A human is only alerted once exploitability is proven.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is where Microsoft&#8217;s agentic AI approach becomes significant. Single-model scanners handle one task at a time and routinely miss cross-file bugs. MDASH auditor agents are built to detect those patterns, and the debater cohort ensures findings cannot be dismissed.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Has_MDASH_Found\"><\/span><strong>What Has MDASH Found?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In May 2026, MDASH found 16 new vulnerabilities in the Windows networking and authentication stack. Four were identified as critical.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The most severe was CVE-2026-33827, a<a href=\"https:\/\/www.first.org\/cvss\/\"> CVSS<\/a> 8.1 use-after-free in tcpip.sys that could be triggered remotely with no authentication required, just by sending malformed IPv4 packets. CVE-2026-33824 is a CVSS 9.8 double-free in the IKEEXT service that spanned six source files and could not have been identified by analyzing any one of them individually. It can be triggered by an unauthenticated attacker over UDP port 500, exactly the kind of flaw that standard tools walk past.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In an internal test, MDASH identified all 21 vulnerabilities with zero false positives.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On the CyberGym benchmark, which covers 1,507 real-world tasks from 188 open-source projects, MDASH scored 88.45%. By Build 2026, that had risen to 96.55%, roughly a 10-point jump in under three weeks. On retrospective tests against pre-patch Windows components, it hit 96% recall for confirmed<a href=\"https:\/\/msrc.microsoft.com\/\"> MSRC<\/a> cases in clfs.sys over five years and 100% for tcpip.sys.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Is_the_Relationship_Between_MDASH_Defender_and_GitHub\"><\/span><strong>What Is the Relationship Between MDASH, Defender, and GitHub?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Production risk indicators, such as internet exposure and data sensitivity, are automatically imported into the Microsoft Defender Portal from validated MDASH results. Security teams keep using the same user interface for prioritization.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Meanwhile, GitHub Copilot Autofix makes remediations based on the MDASH findings verified in the GitHub workflow. Developers are given the fix in their editor without switching to another tool. Role-based access control mechanisms keep the vulnerability details confidential until the patch is made public.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">First MDASH locates and verifies the bug, then Defender puts it on the priority list, and finally, Copilot Autofix prepares the patch.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_This_Means_for_Enterprise_Security_Teams\"><\/span><strong>What This Means for Enterprise Security Teams<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This Microsoft security news marks one of the biggest shifts in enterprise defense in recent years. AI is no longer just helping analysts. It&#8217;s analyzing, presenting results, and generating proof-of-concept exploits before a human ever sees the alert.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It cuts both ways. Defensively, MDASH can locate vulnerabilities much more quickly than even the best human teams. Then again, malicious actors are also building similar pipelines. In its<a href=\"https:\/\/www.microsoft.com\/en-us\/corporate-responsibility\/cybersecurity\/microsoft-digital-defense-report-2025\/\"> 2025 Digital Defense Report<\/a>, Microsoft highlighted that state-sponsored hackers are using AI not only to speed up their vulnerability identification but also to carry out larger-scale attacks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This latest AI innovation from Microsoft means the attacker-defender speed gap is quietly getting smaller. MDASH is designed to close that gap from the inside out.<\/p>\n\n\n\n<style>\n  .threatcop-banner {\n    background-color: #02022e;\n    border: 2px solid #00bf63;\n    border-radius: 12px;\n    padding: 12px 24px;\n    display: flex;\n    justify-content: space-between;\n    align-items: center;\n    max-width: 1100px;\n    margin: 20px auto;\n    color: #ffffff;\n    font-family: Arial, sans-serif;\n  }\n\n  .threatcop-banner-text {\n    font-size: 18px;\n    font-weight: 500;\n  }\n\n  .threatcop-banner-button {\n    background-color: #00bf63;\n    color: #ffffff;\n    padding: 8px 20px;\n    border-radius: 8px;\n    text-decoration: none;\n    font-weight: 500;\n    white-space: nowrap;\n    transition: 0.2s ease;\n    font-size: 15px;\n  }\n\n  .threatcop-banner-button:hover {\n    opacity: 0.9;\n  }\n\n  @media (max-width: 768px) {\n    .threatcop-banner {\n      flex-direction: column;\n      text-align: center;\n      gap: 10px;\n    }\n  }\n<\/style>\n\n<div class=\"threatcop-banner\">\n  <div class=\"threatcop-banner-text\">\n    Discuss Your Organization\u2019s Human Risk Challenges\n  <\/div>\n  <a href=\"https:\/\/threatcop.com\/contact-us?utm_source=thrm_summerized_blog\" class=\"threatcop-banner-button\">\n    Book a Meeting\n  <\/a>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_MDASH_Does_Not_Cover\"><\/span><strong>What MDASH Does Not Cover<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">MDASH finds and validates vulnerabilities in code. It does not protect against <a href=\"https:\/\/threatcop.com\/blog\/weakest-link-in-cyber-security\/\">employees who click phishing links<\/a>, forward infected attachments, or hand over credentials on a convincing phone call.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Both exposures exist in parallel. An AI vulnerability scanner reduces exposure at the code level but does nothing at the human layer. A team that secures one door and leaves the other open is still exposed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As part of this Microsoft announcement, it is worth noting that tools like MDASH only operate at the code layer. The human layer needs its own defense. <a href=\"https:\/\/threatcop.com\/threatcop-security-awareness-training\">Threatcop&#8217;s security awareness training platform<\/a> is built for that. It simulates phishing, vishing, smishing, and ransomware attacks, measures each employee&#8217;s likelihood of falling for them, and uses AI-driven reports to flag the highest-risk areas before attackers get there first.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Code security and a trained workforce protect two different attack surfaces. You need both.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Frequently_Asked_Questions\"><\/span><strong>Frequently Asked Questions<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n<style>#sp-ea-14729 .spcollapsing { height: 0; overflow: hidden; transition-property: height;transition-duration: 300ms;}#sp-ea-14729.sp-easy-accordion>.sp-ea-single {margin-bottom: 10px; border: 1px solid #e2e2e2; }#sp-ea-14729.sp-easy-accordion>.sp-ea-single>.ea-header a {color: #444;}#sp-ea-14729.sp-easy-accordion>.sp-ea-single>.sp-collapse>.ea-body {background: #fff; color: #444;}#sp-ea-14729.sp-easy-accordion>.sp-ea-single {background: #eee;}#sp-ea-14729.sp-easy-accordion>.sp-ea-single>.ea-header a .ea-expand-icon { float: left; color: #444;font-size: 16px;}<\/style><div id=\"sp_easy_accordion-1782131386\"><div id=\"sp-ea-14729\" class=\"sp-ea-one sp-easy-accordion\" data-ea-active=\"ea-click\" data-ea-mode=\"vertical\" data-preloader=\"\" data-scroll-active-item=\"\" data-offset-to-scroll=\"0\"><div class=\"ea-card ea-expand sp-ea-single\"><h3 class=\"ea-header\"><a class=\"collapsed\" id=\"ea-header-147290\" role=\"button\" data-sptoggle=\"spcollapse\" data-sptarget=\"#collapse147290\" aria-controls=\"collapse147290\" href=\"#\" aria-expanded=\"true\" tabindex=\"0\"><i aria-hidden=\"true\" role=\"presentation\" class=\"ea-expand-icon eap-icon-ea-expand-minus\"><\/i> What is MDASH?<\/a><\/h3><div class=\"sp-collapse spcollapse collapsed show\" id=\"collapse147290\" data-parent=\"#sp-ea-14729\" role=\"region\" aria-labelledby=\"ea-header-147290\"> <div class=\"ea-body\"><p><span style=\"font-weight: 400\">MDASH is a Multi-Model Agentic Scanning Harness.
