Who’s Tracking You? Use This New Service to Find Out

It can be daunting to determine who's responsible for showing ads on the websites we visit, or who's harvesting data from the mobile apps we use every day. That information is already semi-public, but it is not easily parsed and traditionally much of it has remained walled away in the hands of large advertising platforms. Not anymore: A powerful and free new service called DecryptAds scrapes and correlates this adtech data and makes it simple to quickly learn a great deal about the entities that are tracking you.Czytaj całość ↵Źródło — otwiera w nowej karcie

Canadian Man Pleads Guilty in Snowflake Extortions

A 26-year-old Canadian man once described as one of the most consequential cybercrime threat actors of 2024 has pleaded guilty to computer fraud and conspiracy to hack and extort more than 165 organizations that used the cloud data storage provider Snowflake. Connor Riley Moucka, of Kitchener, Ontario, also admitted to stealing call and text history records of more than 100 million AT&T customers.Czytaj całość ↵Źródło — otwiera w nowej karcie

Read This Before You Buy That TV Streaming Stick

Security experts have been sounding the alarm for years about the risks of using generic TV boxes that promise unlimited content streaming for a one-time fee, warning that they secretly rent the user's Internet connection out to strangers. But a groundbreaking new analysis finds these devices also routinely spoof themselves as mobile phones clicking ads on AI-generated websites as part of sprawling operation that seeks to defraud online merchants and advertising networks.Czytaj całość ↵Źródło — otwiera w nowej karcie

LG to Ban Residential Proxies from Smart TV Apps

The home appliance giant LG Electronics USA said this week it plans to suspend any apps built for its smart TVs that turn one's television into an always-on residential proxy node. The move comes less than a month after researchers found that more than 42 percent of games and other apps available for download on LG's webOS store allow unknown third-parties to route their Internet traffic through a user's TV.Czytaj całość ↵Źródło — otwiera w nowej karcie

A 0-click exploit chain for the Pixel 10: When a Door Closes, a Window Opens

We recently published an exploit chain for the Google Pixel 9 that demonstrated it was possible to go from a zero-click context to root on Android in just two exploits. The Dolby 0-click vulnerability existed across all of Android, until it was patched in January 2026. While we had an exploit chain for the Pixel 9, we wanted to see if it was possible to write a similar exploit chain for Pixel 10. Updating the Dolby Exploit Altering our exploit for CVE-2025-54957 was fairly straightforward. The majority of needed changes involved updating offsets calculated for the specific version of the libra…Czytaj całość ↵Źródło — otwiera w nowej karcie

On the Effectiveness of Mutational Grammar Fuzzing

Mutational grammar fuzzing is a fuzzing technique in which the fuzzer uses a predefined grammar that describes the structure of the samples. When a sample gets mutated, the mutations happen in such a way that any resulting samples still adhere to the grammar rules, thus the structure of the samples gets maintained by the mutation process. In case of coverage-guided grammar fuzzing, if the resulting sample (after the mutation) triggers previously unseen code coverage, this sample is saved to the sample corpus and used as a basis for future mutations. This technique has proven capable of finding…Czytaj całość ↵Źródło — otwiera w nowej karcie

A Deep Dive into the GetProcessHandleFromHwnd API

In my previous blog post I mentioned the GetProcessHandleFromHwnd API. This was an API I didn’t know existed until I found a publicly disclosed UAC bypass using the Quick Assist UI Access application. This API looked interesting so I thought I should take a closer look. I typically start by reading the documentation for an API I don’t know about, assuming it’s documented at all. It can give you an idea of how long the API has existed as well as its security properties. The documentation’s remarks contain the following three statements that I thought were interesting: If the caller has UIAccess…Czytaj całość ↵Źródło — otwiera w nowej karcie

Bypassing Administrator Protection by Abusing UI Access

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…Czytaj całość ↵Źródło — otwiera w nowej karcie

Breaking the Sound Barrier, Part II: Exploiting CVE-2024-54529

In the first part of this series, I detailed my journey into macOS security research, which led to the discovery of a type confusion vulnerability (CVE-2024-54529) and a double-free vulnerability (CVE-2025-31235) in the coreaudiod system daemon through a process I call knowledge-driven fuzzing. While the first post focused on the process of finding the vulnerabilities, this post dives into the intricate process of exploiting the type confusion vulnerability. I’ll explain the technical details of turning a potentially exploitable crash into a working exploit: a journey filled with dead ends, cr…Czytaj całość ↵Źródło — otwiera w nowej karcie

Bypassing Windows Administrator Protection

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…Czytaj całość ↵Źródło — otwiera w nowej karcie

A 0-click exploit chain for the Pixel 9 Part 3: Where do we go from here?

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…Czytaj całość ↵Źródło — otwiera w nowej karcie
