AI threats in the wild: The current state of prompt injections on the web

Google's Threat Intelligence teams are actively monitoring Indirect Prompt Injection (IPI) attacks, a major security concern for AI systems. They investigated real-world IPI exploitation by scanning the public web using Common Crawl, a large web archive. Their research aimed to identify how threat actors are using IPI. The team developed a multi-stage approach, including pattern matching, classification with Gemini, and manual review, to filter out false positives. The analysis revealed attempts at manipulating AI, including harmless pranks, SEO, and malicious activities. Malicious attempts included data exfiltration and destruction, though these were generally unsophisticated. The findings suggest that IPI attack sophistication is low but increasing, with a 32% rise in malicious attempts observed. Google anticipates a rise in both the scale and sophistication of IPI attacks in the future. They are investing in model hardening and red teams, including external researcher participation through a vulnerability reward program. Google's real-time data processing capabilities allow them to identify and neutralize threats. They have provided resources for further exploration of their GenAI security research.

Bringing Rust to the Pixel Baseband

Google is enhancing Pixel device security, specifically targeting modem vulnerabilities. The project focuses on integrating a memory-safe Rust DNS parser into the modem firmware. This integration aims to mitigate memory-safety vulnerabilities and reduce attack surfaces. The team selected the "hickory-proto" Rust library and enabled "no_std" support for compatibility. The process involved adapting the library and its dependencies for use in a bare-metal environment. Rust code was compiled into a static library and integrated into the existing build system. A performance issue concerning weak symbols during linking was addressed and resolved. FFI was used to expose Rust APIs to C++ for DNS parsing and callbacks. The team employed "cargo-gnaw" for building third-party crates, improving maintainability. This marks the first step towards wider use of memory-safe code within the cellular baseband. The introduction of Rust for DNS parsing enhances the security posture for future Pixel devices. This project sets a strong foundation for future security upgrades.

Protecting Cookies with Device Bound Session Credentials

Chrome is rolling out Device Bound Session Credentials (DBSC) to combat session theft, a significant threat where malware steals session cookies. This new feature is now publicly available for Windows users on Chrome 146 and will soon expand to macOS. DBSC revolutionizes session security by cryptographically binding authentication sessions to a specific device, moving from reactive detection to proactive prevention. It utilizes hardware-backed security modules like TPMs and Secure Enclaves to generate unexportable public/private key pairs. Website servers can then verify Chrome's possession of the private key before issuing short-lived session cookies. This ensures that any stolen cookies, lacking the private key, become useless to attackers. DBSC is designed with user privacy as a core tenet, preventing cross-session correlation and avoiding device fingerprinting. The protocol was developed as an open web standard through W3C, with collaboration from Microsoft and industry partners. Origin Trials and engagements with platforms like Okta have helped refine its effectiveness for diverse web needs. Future development will focus on securing federated identity, enhancing registration capabilities, and exploring software-based keys for broader device support.

HTTPS certificate industry phasing out less secure domain validation methods

The Chrome Root Program and the CA/Browser Forum have implemented new security requirements for HTTPS certificate issuers to create a more secure internet. These initiatives aim to retire outdated Domain Control Validation methods that rely on weaker verification signals, such as physical mail, phone calls, or emails. The deprecation of these methods will be phased in, with full security value realized by March 2028, allowing website operators to transition smoothly. Domain Control Validation is a security-critical process that ensures certificates are only issued to the legitimate domain operator, preventing unauthorized entities from obtaining a certificate. The process involves a Certification Authority verifying that the requestor controls the domain, often through challenge-response mechanisms. Historically, other methods validated control through indirect means, which have been proven vulnerable to attacks. The recently passed CA/Browser Forum Server Certificate Working Group Ballots introduce a phased sunset of weaker Domain Control Validation methods, replacing them with robust, automated alternatives. The sunsetted methods include those relying on email, phone, and reverse lookup, which will be replaced by standardized, modern, and auditable methods. These changes will make it harder for attackers to trick a CA into issuing a certificate for a domain they don't control, reducing the risk of stale or indirect signals being abused. The ultimate goal of these initiatives is to create a safer browsing experience for everyone by removing weak links in how trust is established on the internet.

Further Hardening Android GPUs

Google's Android Red Team partnered with Arm to conduct a security analysis of the Mali GPU, a component used in billions of Android devices worldwide. The goal of this collaboration was to identify and fix vulnerabilities in the GPU software and firmware stack. The Mali GPU has become a critical target for attackers due to its complexity and privileged access to the system, with the majority of Android kernel driver-based exploits targeting the GPU since 2021. To improve security, the team focused on reducing the driver's attack surface by restricting access to certain GPU IOCTLs. The team used SELinux to harden the GPU by blocking access to deprecated and debug IOCTLs in production, while allowing access to instrumentation IOCTLs only for debugging tools. The approach was rolled out in stages, starting with an "opt-in" policy and moving to an "opt-out" policy, to minimize the impact on developers. The team also provided step-by-step instructions on how to implement a robust SELinux policy to filter GPU ioctls. The core principle is to create a flexible, platform-level macro that allows each device to define its own specific lists of GPU ioctl commands to be restricted. The Android security team is committed to collaborating with ecosystem partners to drive broader adoption of this approach to help harden the GPU. By reducing the attack surface, this approach provides strong protection against existing and future vulnerabilities, and the team is working to raise the bar on GPU security to ensure the Mali GPU driver and firmware remain highly resilient against potential threats. The partnership with Arm and the use of SELinux have been crucial in achieving this goal, and the team is committed to continuing this effort to improve the security of Android devices.

Rust in Android: move fast and fix things

Android's memory safety strategy is yielding significant, compounding gains by focusing on vulnerability prevention in new code. For the first time, memory safety vulnerabilities represent less than 20% of total vulnerabilities in 2025 data. This approach not only fixes issues but also accelerates development velocity. The adoption of Rust has led to a 1000x reduction in memory safety vulnerability density compared to C and C++. Furthermore, Rust changes exhibit a 4x lower rollback rate and spend 25% less time in code review, making it a faster and safer development path. Android is expanding Rust's reach across its software stack, including the Linux kernel, firmware, and first-party applications. While Rust does have memory safety considerations, particularly in unsafe blocks, the overall vulnerability density remains drastically lower than C/C++. A recent near-miss vulnerability in unsafe Rust was mitigated by Scudo's hardened allocator, highlighting the importance of multiple security layers. Continuous improvement in understanding and managing unsafe Rust code, along with robust allocators and crash reporting, further enhances security. Ultimately, this shift demonstrates that improved security does not necessarily come at the cost of development speed or product stability.

HTTPS by default

Chrome will enable "Always Use Secure Connections" by default for all users in October 2026, starting with Chrome 154. This change aims to enhance user safety by prioritizing HTTPS connections and warning users before they access sites without secure protocols. The decision follows a decade of increasing HTTPS adoption, which has now plateaued around 95-99% for public sites. While this represents a significant security improvement, the remaining HTTP navigations, though a small percentage, still pose risks. Attackers can exploit insecure HTTP connections to redirect users to malicious sites, leading to malware or data breaches. The "Always Use Secure Connections" setting, first introduced as an opt-in feature in 2022, will now be the default. This mode will attempt HTTPS connections first and display a bypassable warning if HTTPS is unavailable. To minimize user annoyance, Chrome will avoid repeatedly warning about the same insecure site. The primary remaining use of HTTP is for private, local network sites, where obtaining HTTPS certificates is more complex. However, a new local network access permission in Chrome is designed to facilitate migrating these sites to HTTPS. Before the full rollout, Chrome 147 in April 2026 will enable this setting for users with Enhanced Safe Browsing protections. Website developers and IT professionals are encouraged to test and migrate their sites to HTTPS now. Future work will focus on further reducing barriers to HTTPS adoption, particularly for local network sites.

Supporting Rowhammer research to protect the DRAM ecosystem

Rowhammer is a hardware vulnerability in DRAM where repeated access to one memory row can corrupt data in adjacent rows. This can be exploited for unauthorized access, privilege escalation, or denial of service. While mitigations like ECC and Target Row Refresh (TRR) exist, their effectiveness against sophisticated attackers is questionable. Google has supported research and developed test platforms to analyze DDR5 memory and discover new attacks. Rowhammer exploits DRAM's need for periodic refresh cycles to maintain data, and aggressive access can cause bit flips. Attackers can leverage this by inducing bit flips and coercing the system to use those corrupted pages. Previous research has demonstrated Rowhammer attacks from software, making it a concern for multi-tenant environments like the cloud. Target Row Refresh (TRR) attempts to mitigate this by refreshing victim rows when adjacent aggressor rows are accessed frequently. However, attacks like TRRespass have shown TRR can be bypassed. Google collaborated on PRAC, a new mitigation that deterministically tracks memory row activations. Current DDR5 systems often rely on probabilistic measures like ECC and enhanced TRR, whose effectiveness against new attacks was unclear. Assessing Rowhammer requires understanding how mitigations work, how software accesses translate to low-level commands, and the role of host-side mitigations. Reverse-engineering proprietary DRAM mechanisms and analyzing DDR traffic necessitate specialized test platforms. Google partnered with Antmicro to create open-source FPGA-based Rowhammer test platforms for RDIMMs and SO-DIMMs. Using these platforms, researchers developed custom attack patterns that bypassed enhanced TRR on DDR5, leading to the first Rowhammer privilege escalation on a production desktop. Current mitigations are insufficient due to probabilistic countermeasures lacking sufficient entropy and ECC not being designed as a security measure. Memory encryption without integrity checks is also not a viable defense. Google continues to work on improving countermeasures and collaborates with partners to enhance analysis and testing, sharing findings with the broader ecosystem.

Sustaining Digital Certificate Security - Upcoming Changes to the Chrome Root Store

Google Chrome has announced the removal of default trust of Chunghwa Telecom and Netlock due to patterns of concerning behavior observed over the past year. The Chrome Root Program Policy requires Certification Authority certificates to provide value to Chrome end users that exceeds the risk of their continued inclusion. Chrome's confidence in the reliability of Chunghwa Telecom and Netlock as CA Owners has diminished, leading to a loss of integrity and trust. As a result, Chrome will no longer trust new TLS certificates issued by these CAs starting from August 1, 2025, in versions 139 and higher. This change will affect certificates issued after July 31, 2025, but will not impact existing certificates issued before this date. Website operators can determine if they are affected by using the Chrome Certificate Viewer and are recommended to transition to a new publicly-trusted CA Owner as soon as possible. To minimize disruption, Chrome has introduced a command-line flag that allows administrators and power users to simulate the effect of the change before it takes effect. Enterprises can override Chrome Root Store constraints by installing the corresponding root CA certificate as a locally-trusted root on the platform Chrome is running. The change will occur in versions of Chrome 139 and greater on Windows, macOS, ChromeOS, Android, and Linux, but will not affect Chrome for iOS due to Apple policies. Overall, the goal of this change is to safeguard Chrome users and preserve the integrity of the Chrome Root Store by ensuring that only trusted and reliable CA Owners are included.

Tracking the Cost of Quantum Factoring

Google Quantum AI is working on building quantum computers that can solve previously unsolvable problems, but this also means that large-scale quantum computers could break current public key cryptography algorithms. To address this, Google has been working with the US National Institute of Standards and Technology (NIST) to develop and transition to post-quantum cryptography (PQC) that is resistant to quantum computing attacks. A recent study demonstrated that a quantum computer with 1 million noisy qubits could break 2048-bit RSA encryption in one week, a 20-fold decrease from previous estimates. This underscores the importance of migrating to PQC standards in line with NIST recommended timelines. The reduction in physical qubit count comes from better algorithms and better error correction. The security implications of quantum computers are significant, particularly for encryption in transit and digital signatures. Google has started encrypting traffic with PQC algorithms and has added PQC signature schemes in Cloud KMS. The NIST internal report recommends deprecating vulnerable systems after 2030 and disallowing them after 2035. Google's work highlights the importance of adhering to this recommended timeline. The transition to PQC is complex, but necessary to prevent "store now, decrypt later" attacks.

Using AI to stop tech support scams in Chrome

Tech support scams are a growing form of cybercrime where scammers trick users into believing their computer has a serious problem and then extort money or gain unauthorized access. These scams often use alarming pop-up warnings, full-screen takeovers, and disable keyboard and mouse input to create a sense of crisis. Chrome has always worked with Google Safe Browsing, and now with Chrome 137, it will offer an additional protection using the Gemini Nano large language model (LLM) to detect potentially dangerous sites. The LLM will generate signals that will be used by Safe Browsing to deliver higher confidence verdicts about scams. The on-device approach allows Chrome to detect and block attacks that haven't been crawled before and see threats the way users see them. When a user navigates to a potentially dangerous page, Chrome will evaluate the page using the LLM and send the information to Safe Browsing for a final verdict. If the page is likely to be a scam, it will show a warning interstitial. This feature preserves performance and privacy, and Chrome plans to use it to detect other scam types and roll it out to Chrome on Android later this year.

Taming the Wild West of ML: Practical Model Signing with Sigstore

The Google Open Source Security Team, in partnership with NVIDIA and HiddenLayer, has launched the first stable version of a model signing library as part of the Open Source Security Foundation. This library allows users to verify that the model used by an application is the same one created by the developers, using digital signatures like those from Sigstore. The rapid evolution of large language models (LLMs) has opened the door to new security threats, including model and data poisoning, prompt injection, and prompt evasion. The ML supply chain process is vulnerable to tampering, as models are an uninspectable collection of weights that can be altered by attackers. To achieve trust in models, users need to verify their integrity and provenance, which can be done through cryptographic signing. The ML supply chain involves three stages: training, fine-tuning, and embedding into an application, each handled by different teams or companies, creating opportunities for tampering. Model signing can prevent tampering by verifying the model's integrity at each stage. The released model signing library is a Python package that supports Sigstore and traditional signing methods, and can handle the scale of ML models. The goal is to extend model signing to include datasets and other ML-related artifacts, and to build tamper-proof metadata records that can automate incident response. The project aims to create a trust ecosystem for ML, and invites the open source community to join and shape its future.

Retrofitting Spatial Safety to hundreds of millions of lines of C++

Spatial memory safety vulnerabilities, which occur when code accesses memory outside its intended bounds, are a major security risk and have been exploited by attackers to compromise systems and sensitive data. According to Google's Project Zero, these vulnerabilities represent 40% of in-the-wild memory safety exploits over the past decade. To address this, Google is taking a comprehensive approach to memory safety, including using memory-safe languages in new code and retrofitting secure-by-design principles to existing C++ codebases. One key strategy is to implement bounds checking for common data structures, starting with hardening the C++ standard library (libc++). Hardened libc++ introduces security checks to catch vulnerabilities such as out-of-bounds accesses in production. Google has made hardened libc++ default across its server-side production systems, improving spatial memory safety across its services. The performance impact of these changes was surprisingly low, with an average 0.30% impact across services. Enabling hardened libc++ has already prevented exploits, reduced crashes, and improved code correctness, with over 1,000 bugs uncovered and a 30% reduction in segmentation faults. Google is committed to expanding bounds checking to other libraries and migrating its code to Safe Buffers, requiring all accesses to be bounds checked. The company encourages other organizations using C++ to enable their standard library's hardened mode universally by default.
