Description
Codename MDASH represents an advanced code scanning tool integrated within Microsoft Defender, leveraging a multi-modal AI framework to uncover, verify, and address vulnerabilities with a level of insight that surpasses conventional static analysis methods. This system enhances the Defender CLI by introducing a multistage process where specialized agents work collaboratively through four distinct phases. Initially, the preparation stage organizes ranked files based on risk, utilizing call-graph analysis and evaluating code complexity to identify functions with the highest likelihood of containing vulnerabilities. The scanning phase then transmits this prioritized code to over 100 specialized agents, including those focused on injection flaws, memory safety issues, and authentication bypasses, ensuring each agent targets a specific category of vulnerability. Following this, the validation phase employs taint analysis, type resolution through Language Server Protocol servers, and a debate among multi-model agents to improve confidence levels and minimize false positives. Finally, the deduplication step merges overlapping findings into a comprehensive set of unique and actionable results, enhancing the overall efficiency of vulnerability management processes. This innovative approach signifies a new era in threat detection and remediation within software development.
Description
GPT-5.5-Cyber is a specialized cybersecurity model built for advanced defenders who need deeper capability and more flexible support for authorized security work. The updated model is designed to reduce unnecessary refusals while improving performance on vulnerability discovery, validation, patch development, and remediation workflows. It can analyze large codebases, identify security-relevant components, determine whether vulnerable code is reachable, validate likely issues in controlled environments, and help prepare evidence for human review. GPT-5.5-Cyber is intended to move defenders through the full remediation process, from finding a vulnerability to testing and supporting a fix. The model retains the general-purpose intelligence of GPT-5.5 while adding stronger cyber-specific performance for complex, long-running tasks. Benchmark results show higher scores than GPT-5.5 on CyberGym, ExploitGym, and SEC-bench Pro, including stronger single-model performance in reproducing known vulnerabilities and evaluating complex software targets. GPT-5.5-Cyber is positioned for verified defenders whose work requires advanced cyber capabilities and more permissive behavior than standard access models. Its deployment approach includes stronger verification, monitoring, scoped controls, and review to support responsible use. GPT-5.5-Cyber helps security teams identify actionable issues, reduce noise, validate findings, and land safer fixes across demanding software security workflows.
