I found a critical CVE in a top AI agent framework. Here's what it taught me about how we're all building agents wrong.

Nobody told me the scariest part of building AI agents isn't the hallucinations. It's the attack surface you're quietly shipping to production while obsessing over your prompt. I found out the hard way. The vulnerability that should not have existed While contributing to OpenHands (one of the top open-source AI agent frameworks), I discovered a path traversal vulnerability now officia...

You wake up, grab coffee, and nothing works. Grafana won't load. Your reverse proxy is throwing 502s. SSH to your machines by hostname? Nope. But pinging by IP? Works fine. Congratulations, your domain just got added to a DNS blocklist and your entire homelab infrastructure fell over like dominoes. I hit this exact scenario a few months ago with a domain I'd been using for my lab for over a year...

How to Crack the SAM Database in Kali Linux | Windows Password Hash Extraction Guide

In this guide, I will show you an approach to crack the Windows SAM database NTLM hashes. Before cracking, you first need to obtain these three files from the target system: SAM, SYSTEM, and SECURITY. I had a .ova file of a Windows virtual machine, so I will demonstrate how to extract them from that image. First, you need to dump the target system’s image. If it is a VM or virtual disk image, then...

Fixing Wayland crashes in Tauri AppImage (linuxdeploy GTK issue)

I’ve been building a video player(Soia Media Player) with Tauri 2.0 that requires native Wayland rendering on Linux. Packaging it as an AppImage on Linux looked trivial at first—but the app kept crashing on startup. Turns out, it wasn’t a library compatibility issue like I initially thought. The real problem comes from the official packaging script of this project 1: The Wayland Crash:...

A Truth Filter for AI Output: An Experiment with Property-Based Testing

An AI wrote me a 36-kilobyte paper on how to build a second brain. It had theorems, proof sketches, and citation chains, and it read like the real thing. I wanted to know which parts of it actually were. So I took every falsifiable claim in the paper and ran it through a property-based testing harness — the same kind of tool Jepsen, TigerBeetle, and the Hypothesis ecosystem use to break distribu...

Overview: Where we are and What Is Still Missing In the previous part of this series, we made our fake secure channel much less fake. We started with the broken encrypted transport from Part 1, added integrity with HMAC, added sequence numbers to make the record layer less naive, and then moved to AEAD — the approach modern systems usually use to protect records. At that point, our pr...
