ESET researchers present technical details on a recent data destruction incident affecting a company in Poland’s energy sector

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, creative problem solving, and ultimately, success. The Vulnerability: A Quick Recap If you haven’t already, I highly recommend reading my detailed writeup on this vulnerability before proceeding. As a refresher, CVE-2024-54529 is a type confusion vulnerability within the com.apple.audio.audiohald Mach service in the CoreAudio framework used by the coreaudiod process.

Posted by Nataliya Stanetsky, Fabricio Ferracioli, Elliot Sisteron, Irene Ang of the Android Security Team Phone theft is more than just losing a device; it's a form of financial fraud that can leave you suddenly vulnerable to personal data and financial theft. That’s why we're committed to providing multi-layered defenses that help protect you before, during, and after a theft attempt. Today, we're announcing a powerful set of theft protection feature updates that build on our existing protections, designed to give you greater peace of mind by making your device a much harder target for criminals. Stronger Authentication Safeguards We've expanded our security to protect you against an even wider range of threats. These updates are now available for Android devices running Android 16+.

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 to bypass the feature to silently gain full administrator privileges. All the issues that I reported to Microsoft have been fixed, either prior to the feature being officially released (in optional update KB5067036) or as subsequent security bulletins. Note: As of 1st December 2025 the Administrator Protection feature has been disabled by Microsoft while an application compatibility issue is

In this post, we’ll look how an adversary can mint authentication cookies for Next.js (next-auth/Auth.js) applications to maintain persistent access to the application as any user. The reason this is important is because of React2Shell, which is a deserialization vulnerability that allows an adversary to run arbitrary code. Much has been discussed about this vulnerability, and you can read up the original details from the finder here.

Elastic Security is designed to enable hypothesis-driven threat hunting at speed and scale. By unifying security telemetry and enabling analytics across clusters, threat hunters can ask complex questions across all their data, correlate signals, and validate hypotheses quickly without manual data stitching.

Posted by Chrome Root Program Team Secure connections are the backbone of the modern web, but a certificate is only as trustworthy as the validation process and issuance practices behind it. Recently, the Chrome Root Program and the CA/Browser Forum have taken decisive steps toward a more secure internet by adopting new security requirements for HTTPS certificate issuers. These initiatives, driven by Ballots SC-080, SC-090, and SC-091, will sunset 11 legacy methods for Domain Control Validation. By retiring these outdated practices, which rely on weaker verification signals like physical mail, phone calls, or emails, we are closing potential loopholes for attackers and pushing the ecosystem toward automated, cryptographically verifiable security. To allow affected website operators to transition smoothly, the deprecation will be phased in, with its full security value realized by March 2028. This effort is a key part of our public roadmap, “Moving Forward, Together,” launc

Posted by Liz Prucka, Hamzeh Zawawy, Rishika Hooda, Android Security and Privacy Team Last year, Google's Android Red Team partnered with Arm to conduct an in-depth security analysis of the Mali GPU, a component used in billions of Android devices worldwide. This collaboration was a significant step in proactively identifying and fixing vulnerabilities in the GPU software and firmware stack. While finding and fixing individual bugs is crucial, and progress continues on eliminating them entirely, making them unreachable by restricting attack surface is another effective and often faster way to improve security. This post details our efforts in partnership with Arm to further harden the GPU by reducing the driver's attack surface. The Growing Threat: Why GPU Security Matters The Graphics Processing Unit (GPU) has become a critical and attractive target for attackers due to its complexity and privileged access to the system. The scale of this threat is significant: since 2021, th

Posted by Nathan Parker, Chrome security team Chrome has been advancing the web’s security for well over 15 years, and we’re committed to meeting new challenges and opportunities with AI. Billions of people trust Chrome to keep them safe by default, and this is a responsibility we take seriously. Following the recent launch of Gemini in Chrome and the preview of agentic capabilities, we want to share our approach and some new innovations to improve the safety of agentic browsing. The primary new threat facing all agentic browsers is indirect prompt injection. It can appear in malicious sites, third-party content in iframes, or from user-generated content like user reviews, and can cause the agent to take unwanted actions such as initiating financial transactions or exfiltrating sensitive data. Given this open challenge, we are investing in a layered defense that includes both deterministic and probabilistic defenses to make it difficult and costly for attackers to cause harm.

The AI industry risks repeating the same cultural failures that contributed to the Space Shuttle Challenger disaster: Quietly normalizing warning signs while progress marches forward. The original term Normalization of Deviance comes from the American sociologist Diane Vaughan, who describes it as the process in which deviance from correct or proper behavior or rule becomes culturally normalized. I use the term Normalization of Deviance in AI to describe the gradual and systemic over-reliance on LLM outputs, especially in agentic systems.

Posted by Aden Haussmann, Associate Product Manager and Sumeet Sharma, Play Partnerships Trust & Safety Lead Android uses the best of Google AI and our advanced security expertise to tackle mobile scams from every angle. Over the last few years, we’ve launched industry-leading features to detect scams and protect users across phone calls, text messages and messaging app chat notifications. These efforts are making a real difference in the lives of Android users. According to a recent YouGov survey1 commissioned by Google, Android users were 58% more likely than iOS users to report they had not received any scam texts in the prior week2. But our work doesn’t stop there. Scammers are continuously evolving, using more sophisticated social engineering tactics to trick users into sharing their phone screen while on the phone to visit malicious websites, reveal sensitive information, send funds or download harmful apps. One popular scam involves criminals impersonating banks or ot

Last week Google released an IDE called Antigravity. It’s basically the outcome of the Windsurf licensing deal from a few months ago, where Google paid some $2.4 billion for a non-exclusive license to the code. Because it’s based on Windsurf, I was curious if vulnerabilities that I reported to Windsurf back in May 2025, long before the deal, would have been addressed in the Antigravity IDE. See Month of AI Bugs for some detailed write-ups.

Posted by Dave Kleidermacher, VP, Platforms Security & Privacy, Google Technology should bring people closer together, not create walls. Being able to communicate and connect with friends and family should be easy regardless of the phone they use. That’s why Android has been building experiences that help you stay connected across platforms. As part of our efforts to continue to make cross-platform communication more seamless for users, we've made Quick Share interoperable with AirDrop, allowing for two-way file sharing between Android and iOS devices, starting with the Pixel 10 Family. This new feature makes it possible to quickly share your photos, videos, and files with people you choose to communicate with, without worrying about the kind of phone they use. Most importantly, when you share personal files and content, you need to trust that it stays secure. You can share across devices with confidence knowing we built this feature with security at its core, protecting your

Posted by Jeff Vander Stoep, Android Last year, we wrote about why a memory safety strategy that focuses on vulnerability prevention in new code quickly yields durable and compounding gains. This year we look at how this approach isn’t just fixing things, but helping us move faster. The 2025 data continues to validate the approach, with memory safety vulnerabilities falling below 20% of total vulnerabilities for the first time. Updated data for 2025. This data covers first-party and third-party (open source) code changes to the Android platform across C, C++, Java, Kotlin, and Rust. This post is published a couple of months before the end of 2025, but Android’s industry-standard 90-day patch window means that these results are very likely close to final. We can and will accelerate patching when necessary. We adopted Rust for its security and are seeing a 1000x reduction in memory safety vulnerability density compared to Android’s C and C++ code. But the biggest surp
