A revisit of remote Spectre attacks on Cloudflare Workers
In 2021, we assessed remote Spectre attacks against Cloudflare Workers. Based on the results, we shipped a production defense called Dynamic Process Isolation (DyPrIs), which identifies maliciously looking scripts and isolates them into separate processes. Since then, newer techniques in the area of stabilizing Spectre attacks have been discovered. To understand if these techniques posed a threat to our Workers production environment, we decided to internally reassess the remote Spectre attack.
What To Know About the US Water Cyber Attacks
In late July 2026, over 30 municipal water systems across Minnesota were targeted in coordinated cyber attacks that disrupted the Operational Technology (OT) used to remotely monitor and control water equipment. The attacks initially unfolded on July 26 and 27, striking multiple automated control systems across the state, including those in Plymouth, Braham and South St. Paul.
Developer secrets management that keeps delivery moving
In March 2025, attackers compromised a GitHub Action used in the development pipelines of more than 23,000 repositories. The malicious code exposed API keys, cloud credentials, SSH keys, and other tokens in workflow logs. Affected teams were advised to review their workflow runs and rotate any credentials the logs exposed.

In AI, No One Can Hear the Sandbox Scream
OpenAI was running a cyber-capability evaluation against advanced models, including GPT-5.6 Sol and a more capable pre-release model with reduced cyber refusals. The environment was meant to be constrained and the model still found brute forced through it.
Cloudflare DDoS Threat Report H1 2026: 1 Tbps attacks soar as DNS floods and geopolitical tensions drive a new wave
Welcome to the 25th edition of Cloudflare's DDoS Threat Report. This is the first half-year edition in the series: rather than publishing separate reports for the first and second quarters of 2026, we have combined our coverage of Q1 and Q2 into a single volume covering January through June 2026.
The Invisible Expansion of the Attack Surface: Shadow AI, MCP, and Third-Party Risk
AI adoption is moving faster than most of us anticipated and, more importantly, faster than most organizations can govern it. Organizations are implementing the use of AI-enabled applications, browser extensions, coding assistants, and automated agents to enable employees to work faster. In many cases, these tools are adopted without security review, procurement approval, or a clear understanding of where organizational data is being sent.
Mythos: When Al becomes the attacker, the network becomes the first line of defense.
Cyber defense in the age of Mythos Advanced AI has fundamentally shifted the security landscape, shrinking the window for vulnerability exploitation from weeks to hours. When standard patching workflows can't keep pace, your network becomes your most critical line of defense. In this video, we explore how Corelight transforms network traffic into actionable security insights to power your SOC. The best data drives the best defense. Discover how to improve your SOC outcomes by up to 300% over legacy data.
How the model broke out of its lab and hacked Hugging Face
An AI model found a way out of its controlled environment by exploiting a third-party vulnerability and gaining internet access.
Active Supply Chain Attack on npm Packages (keyv, cacheable): Immediate Mitigation Required
A sophisticated supply chain attack has actively compromised multiple npm packages, including keyv, cacheable, cacheable-request, flat-cache, file-entry-cache, and possible related adapters. Attackers took control of a popular maintainer’s npm account on or before August 4, 2026, and began publishing trojanized package versions containing a preinstall hook (setup.mjs) as a loader.
