Posted by Elie Burzstein and Marianna Tishchenko, Sec-Gemini teamToday, we’re announcing Sec-Gemini v1, a new experimental AI model focused on advancing cybersecurity AI frontiers. As outlined a year ago, defenders face the daunting task of securing against all cyber threats, while attackers need to successfully find and exploit only a single vulnerability. This fundamental asymmetry has made securing systems extremely difficult, time consuming and error prone. AI-powered cybersecurity workflows have the potential to help shift the balance back to the defenders by force multiplying cybersecurity professionals like never before. Effectively powering SecOps workflows requires state-of-the-art reasoning capabilities and extensive current cybersecurity knowledge. Sec-Gemini v1 achieves this by combining Gemini’s advanced capabilities with near real-time cybersecurity knowledge and tooling. This combination allows it to achieve superior performance on key cybersecurity workflows, including

Posted by the Agentic AI Security Team at Google DeepMindModern AI systems, like Gemini, are more capable than ever, helping retrieve data and perform actions on behalf of users. However, data from external sources present new security challenges if untrusted sources are available to execute instructions on AI systems. Attackers can take advantage of this by hiding malicious instructions in data that are likely to be retrieved by the AI system, to manipulate its behavior. This type of attack is commonly referred to as an "indirect prompt injection," a term first coined by Kai Greshake and the NVIDIA team.To mitigate the risk posed by this class of attacks, we are actively deploying defenses within our AI systems along with measurement and monitoring tools. One of these tools is a robust evaluation framework we have developed to automatically red-team an AI system’s vulnerability to indirect prompt injection attacks. We will take you through our threat model, before describing three att

Posted by Alex Rebert, Security Foundations, and Chandler Carruth, Jen Engel, Andy Qin, Core DevelopersError-prone interactions between software and memory1 are widely understood to create safety issues in software. It is estimated that about 70% of severe vulnerabilities2 in memory-unsafe codebases are due to memory safety bugs. Malicious actors exploit these vulnerabilities and continue to create real-world harm. In 2023, Google’s threat intelligence teams conducted an industry-wide study and observed a close to all-time high number of vulnerabilities exploited in the wild. Our internal analysis estimates that 75% of CVEs used in zero-day exploits are memory safety vulnerabilities.At Google, we have been mindful of these issues for over two decades, and are on a journey to continue advancing the state of memory safety in the software we consume and produce.

Are those bugs security bugs? Specifically, if a user’s clicks and actions result in memory corruption, is that something that an attacker can exploit to harm that user?Our security severity guidelines say “yes, sometimes.” For example, an attacker could very likely convince a user to click an autofill prompt, but it will be much harder to convince the user to step through a whole flow of different dialogs.Even if these bugs aren’t the most easily exploitable, it takes a great deal of time for our security shepherds to make these determinations.

Posted by Sherk Chung, Stephan Chen, Pixel team, and Roger Piqueras Jover, Ivan Lozano, Android teamPixel phones have earned a well-deserved reputation for being security-conscious. In this blog, we'll take a peek under the hood to see how Pixel mitigates common exploits on cellular basebands.Smartphones have become an integral part of our lives, but few of us think about the complex software that powers them, especially the cellular baseband – the processor on the device responsible for handling all cellular communication (such as LTE, 4G, and 5G). Most smartphones use cellular baseband processors with tight performance constraints, making security hardening difficult. Security researchers have increasingly exploited this attack vector and routinely demonstrated the possibility of exploiting basebands used in popular smartphones.The good news is that Pixel has been deploying security hardening mitigations in our basebands for years, and Pixel 9 represents the most hardened baseband we

Posted by Alex Gough, Chrome Security TeamThe Chrome Security Team is constantly striving to make it safer to browse the web. We invest in mechanisms to make classes of security bugs impossible, mitigations that make it more difficult to exploit a security bug, and sandboxing to reduce the capability exposed by an isolated security issue. When choosing where to invest it is helpful to consider how bad actors find and exploit vulnerabilities. In this post we discuss several axes along which to evaluate the potential harm to users from exploits, and how they apply to the Chrome browser.Historically the Chrome Security Team has made major investments and driven the web to be safer. We pioneered browser sandboxing, site isolation and the migration to an encrypted web. Today we’re investing in Rust for memory safety, hardening our existing C++ code-base, and improving detection with GWP-asan and lightweight use-after-free (UAF) detection.

Posted by Jeff Vander Stoep - Android team, and Alex Rebert - Security FoundationsMemory safety vulnerabilities remain a pervasive threat to software security. At Google, we believe the path to eliminating this class of vulnerabilities at scale and building high-assurance software lies in Safe Coding, a secure-by-design approach that prioritizes transitioning to memory-safe languages.This post demonstrates why focusing on Safe Coding for new code quickly and counterintuitively reduces the overall security risk of a codebase, finally breaking through the stubbornly high plateau of memory safety vulnerabilities and starting an exponential decline, all while being scalable and cost-effective.We’ll also share updated data on how the percentage of memory safety vulnerabilities in Android dropped from 76% to 24% over 6 years as development shifted to memory safe languages.Counterintuitive results1 as new memory unsafe development slows down, and new memory safe development starts to take ove

Most exploitable GPU vulnerabilities are in the implementation of the GPU kernel mode modules. These modules are pieces of code that load/unload during runtime, extending functionality without the need to reboot the device.Proactive testing is good hygiene as it can lead to the detection and resolution of new vulnerabilities before they’re exploited. It’s also one of the most complex investigations to do as you don’t necessarily know where the vulnerability will appear (that’s the point!). By combining the expertise of Google’s engineers with IP owners and OEMs, we can ensure the Android ecosystem retains a strong measure of integrity. Why investigate GPUs?Functionality vs. Security Tradeoffs Nobody wants a slow, unresponsive device; any hits to GPU per
