In my last blog post I introduced the new Windows feature, Administrator Protection and how it aimed to create a secure boundary for UAC where one didn’t exist. I described one of the ways I was able to bypass the feature before it was released. In total I found 9 bypasses during my research that have now all been fixed. In this blog post I wanted to describe the root cause of 5 of those 9 issues, specifically the implementation of UI Access, how this has been a long standing problem with UAC that’s been under-appreciated, and how it’s being fixed now. A Question of Accessibility Prior to Wind
A headline feature introduced in the latest release of Windows 11, 25H2 is Administrator Protection. The goal of this feature is to replace User Account Control (UAC) with a more robust and importantly, securable system to allow a local user to access administrator privileges only when necessary. This blog post will give a brief overview of the new feature, how it works and how it’s different from UAC. I’ll then describe some of the security research I undertook while it was in the insider preview builds on Windows 11. Finally I’ll detail one of the nine separate vulnerabilities that I found t
While our previous two blog posts provided technical recommendations for increasing the effort required by attackers to develop 0-click exploit chains, our experience finding, reporting and exploiting these vulnerabilities highlighted some broader issues in the Android ecosystem. This post describes the problems we encountered and recommendations for improvement. Audio Attack Surface The Dolby UDC is part of the 0-click attack surface of most Android devices because of audio transcription in the Google Messages application. Incoming audio messages are transcribed before a user interacts with t
With the advent of a potential Dolby Unified Decoder RCE exploit, it seemed prudent to see what kind of Linux kernel drivers might be accessible from the resulting userland context, the mediacodec context. As per the AOSP documentation, the mediacodec SELinux context is intended to be a constrained (a.k.a sandboxed) context where non-secure software decoders are utilized. Nevertheless, using my DriverCartographer tool, I discovered an interesting device driver, /dev/bigwave that was accessible from the mediacodec SELinux context. BigWave is hardware present on the Pixel SOC that accelerates AV
The Center for AI Standards and Innovation (CAISI) at the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) has published a Request for Information (RFI) seeking insights from industry, academia, and the security
Understanding mDL credential formats Standards in the VDC Ecosystem In our first blog post in this series, we highlighted that VDCs can represent a wide range of credentials, from a driver’s license to a diploma to proof of age. The ability to use VDCs in a wide variety of use cases is a major reason why many are looking at the VDC ecosystem as technology that can change how we present identity and attributes (both in person and online). While credential variety is a good thing, interoperability requires a common set of standards and protocols for issuing, using, and verifying VDCs. The next
