Is it possible to get to a state where memory safety issues would be deterministically mitigated? Our quest to mitigate memory corruption vulnerabilities led us to examine CHERI (Capability Hardware Enhanced RISC Instructions), which provides memory protection features against many exploited vulnerabilities, or in other words, an architectural solution that breaks exploits. We’ve looked at …
The Azure Sphere Security Research Challenge brought together 70 researchers from 21 countries to help secure Azure Sphere customers and expand Microsoft’s partnerships with the global IoT security research community. During the three-month Azure Sphere Security Research Challenge, researchers surfaced 20 Critical or Important severity security vulnerabilities, with Microsoft awarding $374,300 in bounty awards for …
At the Microsoft Security Response Center’s (MSRC), our primary mission is to help protect our customers. One of the ways we do this is by working with security researchers to discover security vulnerabilities in our services and products, and then making sure those that pose a threat to customers get fixed. Many researchers report these …

Machine learning (ML) is an increasingly valuable tool in cyber security as adversaries continually evolve their tactics and techniques to evade detection. As machine learning has advanced and sophisticated ML models have been developed to assist security professionals in protecting the cloud, adversaries have been busy developing malware designed to evade ML models. To proactively …
The Azure Sphere Security Research Challenge is an expansion of Azure Security Lab, announced at Black Hat in August 2019. At that time, a select group of talented researchers was invited to come and do their worst, emulating criminal hackers in a customer-safe cloud environment. This new research challenge aims to spark new high impact …

Announcing the new Xbox Bounty. The Xbox bounty program invites gamers, security researchers, and technologists around the world to help identify security vulnerabilities in the Xbox network and services, and share them with the Microsoft Xbox team through Coordinated Vulnerability Disclosure (CVD).
We are excited to announce the Microsoft Identity Research Project Grant a new opportunity in partnership with the security community to help protect Microsoft customers. This project grant awards up to $75,000 USD for approved research proposals that improve the security of the Microsoft Identity solutions in new ways for both Consumers (Microsoft Account) and Enterprise (Azure Active Directory).
In two previous blog posts ( part 1 and part 2), we talked about using Semmle QL in C and C++ codebases to find vulnerabilities such as integer overflow, path traversal, and those leading to memory corruption. In this post, we will explore applying Semmle QL to web security by hunting for one of the …
