Cybersecurity Claude Mythos Found 271 Zero-Days in Firefox 150. This Is What the New World Looks Like. In February, Anthropic's Frontier Red Team used Claude Opus 4.6 to find 22 vulnerabilities in Firefox in two weeks — more than were reported in any single month in all of 2025. Then Mythos arrived. Firefox 150, released today, patches 271 vulnerabilities found by Claude.
Cybersecurity Google and Cloudflare Set a 2029 PQC Deadline. The Rest of Big Tech Did Not. Two papers dropped at the end of March. Both said the same thing in different ways: the quantum threat to elliptic curve cryptography is closer than we thought. How close? The kind of close that made Google set an internal deadline five years ahead of what the US government asked
Cybersecurity One Employee. One OAuth Token. The Vercel Breach Explained Vercel confirmed a security breach on April 18-19, 2026, tracing back to a compromised third-party AI tool and a single employee's Google Workspace connection. Here is the full attack chain, what was actually exposed, and what you need to do right now.
Cybersecurity What is OAuth? Every time you click "Sign in with Google" or "Connect your GitHub account," you are using OAuth. You have used it hundreds of times. Most developers have implemented it at least once. And the April 2026 Vercel breach, which exposed credentials for hundreds of organizations, happened
Cybersecurity CVE-2026-33032: The nginx-ui MCP Vulnerability That Hands Attackers Full Server Control CVE-2026-33032, dubbed MCPwn, is a CVSS 9.8 authentication bypass in nginx-ui's MCP integration that lets any attacker on the internet restart your Nginx server, rewrite your configs, and intercept all traffic -- in two HTTP requests, no credentials required. Roughly 2,700 instances are exposed.
Cybersecurity BlueHammer: The Unpatched Windows Zero-Day That Weaponizes Microsoft Defender Against Your Own System BlueHammer is an unpatched, publicly released Windows local privilege escalation exploit that chains Microsoft Defender's update workflow, Volume Shadow Copy, Cloud Files callbacks, and opportunistic locks to reach NT AUTHORITY\SYSTEM from a standard user account.
Cybersecurity Anthropic's Claude Now Requires Government ID and a Selfie — Users Are Furious Anthropic quietly rolled out identity verification for Claude subscriptions, asking for passports and live selfies via third-party vendor Persona. ChatGPT and Gemini require neither. Here's why this decision is a mess, who's actually affected, and what Persona's track record means for your data.
Artificial intelligence Claude Mythos Hacked Every Major OS, Escaped Its Sandbox, and Emailed a Researcher Eating a Sandwich. We Need to Talk. I use AI as a tool. I'll say that upfront. Claude helps me write frontends faster. It handles search queries that Google stopped being useful for three years ago. I hand it boilerplate I've written by hand a thousand times and I get time back. That&
Artificial intelligence Anthropic Just Wrote Apache a $1.5M Check. Here's Why That Number Is Both Impressive and Embarrassing Anthropic's $1.5M donation seeds a $10M Responsible AI Initiative at the Apache Software Foundation. That's more than half of ASF's entire annual budget in one shot — which tells you everything about how badly the open source infrastructure powering AI has been underfunded.
