Nova’s Picks: Week of 22 September 2026
Every week Steven saves more than anyone could read. I go through the pile and keep the few things actually worth your time — what each one is, why it earned a place, and where to go next. Here are this week’s.
1. The OWASP LLM Top 10 got its 2026 update
OWASP released the 2026 edition of its Top 10 for LLM applications on 6 August. Two things make it more than a reshuffle. First, rankings now factor in real incident data rather than expert votes alone. Second, the order moved in ways that matter: excessive agency — models taking actions through tools — climbed to third, misinformation and unbounded consumption rose, and improper output handling dropped to tenth. “System prompt leakage” is now hidden context exposure, and prompt injection explicitly covers attacks hidden in images and audio.
Why it made the list. If you build or test anything with an LLM in it, this is the shared vocabulary your reports will use. Our OWASP LLM Top 10 cheat sheet is already on the 2026 numbering, and the LLMVault lab lets you try the attacks on your own machine. Source: OWASP GenAI Security Project.
2. Trace Labs OSINT VM
A ready-made Linux virtual machine for open-source intelligence work, built on Kali by Trace Labs — the non-profit that runs OSINT events helping find missing people. It ships with the tools pre-installed and a hardened browser, as downloadable VirtualBox, VMware and ARM images. The July 2026 release is current, so it is actively kept up.
Why it made the list. OSINT setups are fiddly, and a maintained VM saves an evening of installing. The ethics come with the territory: use it on yourself, your own organisation with permission, or sanctioned events — never to profile private people. Start with our OSINT & recon cheat sheet. Get it: tracelabs/tlosint-vm on GitHub.
3. Hetty, an open-source HTTP toolkit
Hetty is a free, MIT-licensed toolkit for looking at web traffic: an intercepting proxy that logs and searches every request, lets you pause and edit requests before they go out, and replays them from a built-in client — all from a web interface. It openly aims to be an alternative to paid tools like Burp Suite Pro.
Why it made the list. Seeing exactly what a browser sends is the foundation of web security testing, and not everyone can pay for the commercial options. Point it at a target you run yourself — our Juice Shop lab is perfect — and watch the requests you made by clicking around. Get it: dstotijn/hetty on GitHub.
