In Part 1 of this series, I enumerated a few obstacles for engineers taking vibe coding from side projects to production. Part 2 looked at AI usage from the manager's perspective: measuring adoption, understanding the gap, coaching to fill the gap. Both of those were "Day 1" problems: getting started, getting people on board, figuring out the tools. This article focuses on what comes next: the vib
This technical post walks through the design and implementation of Secure Playground: a local web app that simulates prompt-injection attacks against large language models and demonstrates simple defenses. Provide a minimal, reproducible environment to test payloads and defensive strategies. Make it easy to add new providers and run mutation-based red-team experiments. Offer a leaderboard and scor
Metasploitable2 - FTP Exploitation using vsftpd 2.3.4 Backdoor 1. Objective To identify and exploit a known vulnerability in an FTP service running on a vulnerable target machine using industry-standard reconnaissance and exploitation techniques. 2. Lab Environment Component Description Attacker Machine Kali Linux Target Machine Metasploitable2 Network Type Host-only / NAT
A critical kernel privilege escalation that leaves no trace on disk — and how it works It started with a blog post. On April 29, 2026, Theori's research platform Xint Code quietly dropped a URL: copy.fail. Within hours, security teams across the industry were scrambling. A 732-byte Python script — shorter than most .gitignore files — was rooting every major Linux distribution in existence. No race
MCPwn Is Live. We Scanned the Supply Chains of 14 MCP Servers. Here's What We Found. April 18, 2026 MCPwn dropped this week. CVE-2026-33032 — CVSS 9.8, actively exploited, 2,600+ instances exposed. Two HTTP requests. No authentication. Full nginx server takeover. Then MCPwnfluence: CVE-2026-27825 and CVE-2026-27826. The most widely used Atlassian MCP server — SSRF chained with arbitrary file wri
This is Part 1 of a two-part series. Part 2 (coming soon): Connecting to spoke clusters from a controller using multicluster-runtime, driven by ClusterProfile. The Cluster Inventory API (multicluster.x-k8s.io) is driven by SIG-Multicluster and centered on the ClusterProfile resource. It only delivers value when something produces those ClusterProfiles. That something is a cluster manager. Today, t
At the beginning of this series, the problem seemed simple. There were a lot of rocks in the yard. Some were small. Some were large. A few were firmly in what I’ve been calling Engine Block Class. The original idea was straightforward: catalog them, maybe sell a few, and build a small system around the process. Along the way, the project grew. What We Built Across the previous posts, the Backyard
When developers travel, we usually prepare the obvious things. Laptop charger. But there is one dependency that is easy to underestimate until it breaks: mobile internet. A trip to China makes this especially obvious. Not because China is hard to travel in, but because so many basic interactions are mobile-first: navigation, translation, ride-hailing, hotel communication, ticket confirmations, pay
