Building Private Processing for AI tools on WhatsApp

We are inspired by the possibilities of AI to help people be more creative, productive, and stay closely connected on WhatsApp, so we set out to build a new technology that allows our users around the world to use AI in a privacy-preserving way. We’re sharing an early look into Private Processing, an optional capability that enables users to initiate a request to a confidential and secure environment and use AI for processing messages where no one — including Meta and WhatsApp — can access them. To validate our implementation of these and other security principles, independent security researchers will be able to continuously verify our privacy and security architecture and its integrity. AI has revolutionized the way people interact with technology and information, making it possible for people to automate complex tasks and gain valuable insights from vast amounts of data. However, the current state of AI processing — which relies on large language models often running on servers, rather than mobile hardware — requires that users’ requests are visible to the provider. Although that works for many use cases, it presents challenges in enabling people to use AI to process private messages while preserving the level of privacy afforded by end-to-end encryption. ...

Introducing AutoPatchBench: A Benchmark for AI-Powered Security Fixes

We are introducing AutoPatchBench, a benchmark for the automated repair of vulnerabilities identified through fuzzing. By providing a standardized benchmark, AutoPatchBench enables researchers and practitioners to objectively evaluate and compare the effectiveness of various AI program repair systems. This initiative facilitates the development of more robust security solutions, and also encourages collaboration within the community to address the critical challenge of software vulnerability repair. AutoPatchBench is available now on GitHub. AI is increasingly being applied to solve security challenges, including repairing vulnerabilities identified through fuzzing. However, the lack of a standardized benchmark for objectively assessing AI-driven bug repair agents specific to fuzzing has impeded progress in academia and the broader community. Today, we are publicly releasing AutoPatchBench, a benchmark designed to evaluate AI program repair systems. AutoPatchBench sits within CyberSecEval 4, Meta’s new benchmark suite for evaluating AI capabilities to support defensive use cases. It features 136 fuzzing-identified C/C++ vulnerabilities in real-world code repos along with verified fixes sourced from the ARVO dataset. ...

How Meta understands data at scale

Managing and understanding large-scale data ecosystems is a significant challenge for many organizations, requiring innovative solutions to efficiently safeguard user data. Meta’s vast and diverse systems make it particularly challenging to comprehend its structure, meaning, and context at scale. To address these challenges, we made substantial investments in advanced data understanding technologies, as part of our Privacy Aware Infrastructure (PAI). Specifically, we have adopted a “shift-left” approach, integrating data schematization and annotations early in the product development process. We also created a universal privacy taxonomy, a standardized framework providing a common semantic vocabulary for data privacy management across Meta’s products that ensures quality data understanding and provides developers with reusable and efficient compliance tooling. We discovered that a flexible and incremental approach was necessary to onboard the wide variety of systems and languages used in building Meta’s products. Additionally, continuous collaboration between privacy and product teams was essential to unlock the value of data understanding at scale. We embarked on the journey of understanding data across Meta a decade ago with millions of assets in scope ranging from structured and unstructured, processed by millions of flows across many of the Meta App offerings. Over the past 10 years, Meta has cataloged millions of data assets and is classifying them daily, supporting numerous privacy initiatives across our product groups. Additionally, our continuous understanding approach ensures that privacy considerations are embedded at every stage of product development. At Meta, we have a deep responsibility to protect the privacy of our community. We’re upholding that by investing our vast engineering capabilities into building cutting-edge privacy technology. We believe that privacy drives product innovation. This led us to develop our Privacy Aware Infrastructure (PAI), which integrates efficient and reliable privacy tools into Meta’s systems to address needs such as purpose limitation—restricting how data can be used while also unlocking opportunities for product innovation by ensuring transparency in data flows ...

How the April 28, 2025 power outage in Portugal and Spain impacted Internet traffic and connectivity

A massive power outage struck significant portions of Portugal and Spain at 10:34 UTC on April 28, grinding transportation to a halt, shutting retail businesses, and otherwise disrupting everyday activities and services. Parts of France were also reportedly impacted by the power outage. Portugal’s electrical grid operator blamed the outage on a "fault in the Spanish electricity grid”, and later stated that "due to extreme temperature variations in the interior of Spain, there were anomalous oscillations in the very high voltage lines (400 kilovolts), a phenomenon known as 'induced atmospheric vibration'" and that "These oscillations caused synchronisation failures between the electrical systems, leading to successive disturbances across the interconnected European network." ...

Targeted by 20.5 million DDoS attacks, up 358% year-over-year: Cloudflare’s 2025 Q1 DDoS Threat Report

Welcome to the 21st edition of the Cloudflare DDoS Threat Report. Published quarterly, this report offers a comprehensive analysis of the evolving threat landscape of Distributed Denial of Service (DDoS) attacks based on data from the Cloudflare network. In this edition, we focus on the first quarter of 2025. To view previous reports, visit www.ddosreport.com. While this report primarily focuses on 2025 Q1, it also includes late-breaking data from a hyper-volumetric DDoS campaign observed in April 2025, featuring some of the largest attacks ever publicly disclosed. In a historic surge of activity, we blocked the most intense packet rate attack on record, peaking at 4.8 billion packets per second (Bpps), 52% higher than the previous benchmark, and separately defended against a massive 6.5 terabits-per-second (Tbps) flood, matching the highest bandwidth attacks ever reported. ...
