<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Cloudflare is launching a new, per-customer bot detection system that uses machine learning models to analyze website traffic and identify anomalous behavior specific to each application. The new system will leverage a unique defense for every application, with the goal of combating sophisticated, AI-driven web scraping and other malicious bot activities. During validation, 34% of the scraping requests flagged by the new detections would not have been detected by Cloudflare's existing bot score system.

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Model Context Protocol has rapidly become a key standard for connecting AI agents with tools and data, but its flexibility introduces serious risks such as command injection, misconfigurations, prompt injection, and supply chain attacks. Docker addresses these challenges with containerized MCP servers, a policy-enforcing Gateway, and a curated Catalog & Toolkit that provide secure defaults, active security controls, and standardized workflows for safer agentic AI development.

Netflix shifted incident management from a centralized SRE function to an accessible, company-wide practice by adopting Incident.io and investing in cultural change. The intuitive tooling, internal integrations, and lightweight but consistent processes empowered engineers to declare and manage incidents themselves, driving faster responses and continuous learning across teams.

<strong>MCP Horror Stories: The Drive-By Localhost Breach (10 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
A critical vulnerability, CVE-2025-49596, was discovered in MCP Inspector, a debugging tool with over 78,000 weekly downloads, turning it into a drive-by attack platform that compromises developer machines upon visiting a malicious website. The vulnerability, which scores 9.4 out of 10 on the CVSS scale, allows attackers to gain control of the MCP Inspector interface and access private files by exploiting a browser implementation flaw where browsers incorrectly treat the IP address 0.0.0.0 as equivalent to localhost.

<strong>Beyond Winning: Spotify's Experiments with Learning Framework (12 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Spotify's experimentation platform, Confidence, uses the Experiments with Learning (EwL) metric to measure experiment success by whether experiments yielded enough valid information to inform product decisions. Spotify's learning rate is ~64%, but its win rate is ~12%, which emphasizes that most value comes from understanding what doesn't work or detecting regressions, not just shipping improvements.
