Vulnerability hunting with Semmle QL: DOM XSS

Wednesday, November 06, 2019

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 most common type of client-side vulnerabilities: DOM-based cross-site scripting (XSS).

Microsoft Identity Bounty Improvements

Attacking the VM Worker Process

Wednesday, September 11, 2019

In the past year we invested a lot of time making Hyper-V research more accessible to everyone. Our first blog post, “First Steps in Hyper-V Research”, describes the tools and setup for debugging the hypervisor and examines the interesting attack surfaces of the virtualization stack components. We then published “Fuzzing para-virtualized devices in Hyper-V”, which has been the focus of our friends at the Virtualization Security Team.

Azure Security Lab: a new space for Azure research and collaboration

Monday, August 05, 2019

Azure is exceptionally secure. To help keep it that way, we are doubling the top bounty reward for Azure vulnerabilities to $40,000. But we aren’t stopping there. To make it easier for security researchers to confidently and aggressively test Azure, we are inviting a select group of talented individuals to come and do their worst to emulate criminal hackers in a customer-safe cloud environment called the Azure Security Lab.
