🚨👾First post → Awesome research. We compromised the latest version of OpenAI Codex. We prompt injected. We escaped a sandbox. We exfiltrated secrets… And ended up with control over what could be published to the official openai/codex npm package. Prompt injection → RCE → supply chain compromise. Full research by @0xMadder and @_Worty in the comments 👇

Replying to @SandflySecurity
@SandflySecurity 6.0 is really awesome all around, but the machine learning malware classifier is my baby and dramatically increases detection capability on Linux. It was built to hunt for network implants and related malware which are major threats to critical infrastructure providers. Let me discuss just some things it does in this thread.
Log in to answers, not alerts. Sandfly 6.0 is live! Your team opens the dashboard to a ranked list of real threats, with the triage already done. Agentless, and it works with or without AI. Read our blog on the new release: ap1.hubs.ly/H01wk6B0

Microsoft just published Autoruns for Linux 1.0.0, so I created a Velociraptor artifact for it. Linux.Sysinternals.Autoruns covers cron, systemd, XDG, ld.so.preload, udev and more. 🔗 Linux.Sysinternals.Autoruns github.com/Velocidex/velocir… 🔗 Autoruns for Linux github.com/microsoft/Autorun…

you definitely didn't hear this from me, but the most likely exploit chain based on the released PoCs for Able2Shell would be a pre-authentication path from anonymous SOAP access to appliance root.

Welcome to Hotel Calif. We're in lockdown mode. You can check in, but you can never leave. Broccoli is served around the clock. The Brotli bug apparently affected iOS and macOS too. Apple released version 27.2.1 yesterday, fixing this bug among other security issues. This is an important security update. If you haven't updated yet, now's a good time. The demos show what we were able to do with it.

"The remote server request makes it look like it could be a GIF image that is being downloaded. The file is dropped to C:\programdata\ using a filename that looks like a JPEG image." Read the full report: buff.ly/Fi47zHg #DFIR #ThreatIntel

so a botnet...you've made a botnet
You can now connect multiple local computers to the same dot and choose which one it uses for a task. It can build and test your app on a dedicated machine while you keep coding on your laptop.

I can barely believe it myself, but urlscan.io is 10 years old today. Time to reminisce and look back at the things we have built over the past decade, how our platform and company have grown and where we're headed next: urlscan.io/blog/2026/11/09/u…

Online malware analysis sandbox. Detonates a submitted file or URL and publishes the report, and lets you search past public scans by indicator: IP, domain, URL, mutex, registry key, hash or JA3/JA4 fingerprint. Reports are readable without an account; a free tier adds submissions, an API and a command line client. malwagon.com

A lot of people don't realize that Windows has a built-in feature called Windows "Sandbox" that boots up a brand new virtual Windows machine in seconds. So I made an MCP server so you can test your apps inside a throwaway machine in seconds. github.com/shanselman/sandbo…

This is the future of malware. 👀 VOLTA doesn’t just steal your passwords and crypto wallets. It packages everything and sends it to Claude Opus 4.6 with this prompt: “You are a forensic intelligence analyst. Rank what this victim is worth.” If Claude refuses → Kimi K2 → Gemini. We caught the full chain in the sandbox (including the exact request it sent to the AI) Stealers are now outsourcing target prioritization to commercial LLMs. 🚨 app.threat.zone/submission/c…

Changing one letter bypassed an entire admin API in @huggingface chat. One request could trigger bulk internal exports of every user’s private chats, completely unauthenticated. Here’s how. 🧵

Introducing GPT‑6 Cyber: a major advance in security research that pairs stronger capabilities with better model alignment. The model powered the Linux kernel research we announced yesterday, and security teams at companies like Mozilla, Palo Alto Networks, Calif, and Cisco—alongside our own at OpenAI—are already putting it to work. GPT-6 Cyber is available to select Daybreak Red customers and we are expanding access over time. openai.com/index/introducing…
