Mini Shai-Hulud, Miasma, and Hades Worms Target Bioinformatics and MCP Developers via Malicious PyPI Wheels

Mini Shai-Hulud, Miasma, and Hades Worms Target Bioinformatics and MCP Developers via Malicious PyPI Wheels

Socket Threat Research team identified a newer PyPI wave connected to the broader Mini Shai-Hulud, Miasma, and Hades supply chain attacks. This wave expands beyond the 37 malicious PyPI wheels covered in our weekend report and shows that the threat actors are iterating quickly across delivery mechanisms, package themes, and runtime triggers. The campaign has since added 23 newly identified PyPI package-version artifacts, expanding beyond the 37 malicious PyPI wheels covered in our weekend…

Announcing major new donations, and recapping the 2025 fundraiser

Announcing major new donations, and recapping the 2025 fundraiser

This past December, we ran our first fundraiser in six years, setting an ambitious goal of $6M. We ended up receiving a total of $1.8M from small donors and $1.6M in matching from the Survival and Flourishing Fund (SFF) for a total of $3.4M. We’re incredibly grateful for all this support! In the rest of […] The post Announcing major new donations, and recapping the 2025 fundraiser appeared first on Machine Intelligence Research Institute.

Long-Running Agents

Long-Running Agents

The following article originally appeared on Addy Osmani’s blog and is being reposted here with the author’s permission. A long-running AI agent can keep making progress over hours, days, or weeks. It can do this across many context windows and sandboxes, recover from failure, leave structured artifacts behind, and resume where it left off. For […]

Evals in Laravel: How to Prove Your AI Output Is Actually Good

Evals in Laravel: How to Prove Your AI Output Is Actually Good

Your Agent::fake() tests prove your Laravel AI feature runs — not that its output is any good. This evals a real ticket classifier with the AI SDK: a golden dataset for the fields you can check, an LLM-as-judge for the free text you can't, and a regression gate that catches a bad prompt before your customers do.

datasette-agent-edit 0.1a0

Release: datasette-agent-edit 0.1a0 I'm planning several plugins for Datasette Agent which can make edits to existing pieces of text - things like collaborative Markdown editing, updating large SQL queries, and editing SVG files. Agentic editing of text is a little tricky to get right. My favorite published design for this is for the Claude text editor, which implements the following tools: view - view sections of a file, with line numbers added to every line. str_replace - find an exact…

Shai-Hulud Descends to Hades: Miasma Worm Campaign Spreads with New PyPI Wave

Shai-Hulud Descends to Hades: Miasma Worm Campaign Spreads with New PyPI Wave

Socket detected a coordinated PyPI compromise involving 37 malicious wheel artifacts across 19 packages. The compromised releases shipped a *-setup.pth file that attempts to execute automatically during Python startup, download the Bun JavaScript runtime, and run an obfuscated JavaScript payload named _index.js. Socket’s AI malware detection system identified the malicious package cluster minutes after publication. The attack is cross-runtime, and the tradecraft is unmistakably Shai-Hulud /…

Running Python code in a sandbox with MicroPython and WASM

Running Python code in a sandbox with MicroPython and WASM

I've been experimenting with different approaches to running code in a sandbox for several years now, but my latest attempt feels like it might finally have all of the characteristics I've been looking for. I've released it as an alpha package called micropython-wasm, and I'm using it for a code execution sandbox plugin for Datasette Agent called datasette-agent-micropython. Why do I want a sandbox? What I want from a sandbox WebAssembly looks really promising here MicroPython in WebAssembly…
