Claude Mythos halved HAWK's effective key strength and sped up an AES attack 200-800x. What the math actually shows, and what it doesn't mean yet.
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.
A deep-dive into the full cryptographic stack powering every HTTPS connection — RSA-OAEP, AES-GCM, ECDHE key exchange, and a working TLS 1.3 handshake simulation, all built in pure Python from first principles.
For three years the AI industry watched GPUs. Nobody was watching the CPU. Now Intel is warning of six-month lead times, AMD has blown past expectations, and the chip everyone assumed would always be available has become the new bottleneck in the biggest infrastructure buildout since the internet.
Encryption transforms readable data into unreadable ciphertext that only someone with the right key can reverse. It's what makes HTTPS, messaging apps, banking, and password storage work. Here's how it actually functions.
Cipher.getInstance("AES") compiles, runs, encrypts, decrypts, and hands you the weakest mode in the box. Here is the OpenJDK source that makes that decision, and the line where ECB gets chosen for you.
