I’m excited to announce my newest training course, Breaching M365, is now available on-demand through @Antisy_Training.

For $295, you get a full offensive methodology for attacking Microsoft 365 environments, from unauthenticated recon and initial access to OAuth abuse, persistence, privilege escalation, and data harvesting.

@rootsecdev That’s awesome! Those rate limits are super annoying. Feel free to submit a PR when you are ready to make it public! 😉

Introducing Project Glasswing: an urgent initiative to help secure the world’s most critical software.

It’s powered by our newest frontier model, Claude Mythos Preview, which can find software vulnerabilities better than all but the most skilled humans.

So Microsoft Copilot has its own App-Bound Encryption now. The standalone Copilot app (mscopilot.exe) is a full Chromium browser based on Edge, ships with its own elevation_service.exe, a dedicated COM interface (IElevatorCopilot), and a separate ABE key scope.

Decrypting the ABE key gives us some cookies (https://t.co/jDTRHwilyP auth, MUID, MSAL session, Cloudflare tokens) and the Microsoft Account token from the token_service database.

Local Storage also holds MSAL.js cached tokens. An ID token, two access tokens (chatai.readwrite for the Copilot API + https://t.co/Zgut26Y35L for Microsoft Graph), and account metadata for the signed-in MSA.
These use MSAL's own browser-bound CryptoKey encryption, not ABE.

Edge 147 also quietly hardened IElevator2 by switching from oleaut32 to a custom proxy/stub but simultaneously registered IElevatorCopilot with oleautomation. Closed one door, opened another.

Next up: decrypting the MSAL tokens? 🤔

🚨‼️ BREAKING: PyPI package telnyx has been compromised by TeamPCP in yet another supply chain attack.

The malware executes immediately upon importing telnyx. It drops a valid WAV audio file and runs an executable embedded within the frames.

LiteLLM HAS BEEN COMPROMISED, DO NOT UPDATE. We just discovered that LiteLLM pypi release 1.82.8. It has been compromised, it contains litellm_init.pth with base64 encoded instructions to send all the credentials it can find to remote server + self-replicate. link below

Next week at @WWHackinFest I'll present a major update to roadrecon, with some awesome features I wanted to add for a while! Friday 9am in track 1 for those attending 😀

[Graham Helton (too much for zblock) @GrahamHelton3]

Excited to disclose my research allowing RCE in Kubernetes

It allows running arbitrary commands in EVERY pod in a cluster using a commonly granted "read only" RBAC permission. This is not logged and and allows for trivial Pod breakout.

Unfortunately, this will NOT be patched.

Here's a video PoC for Azure Entra ID SignIn Log Bypass in action. I had to make it to help MSRC replicate it (lol). You'll see how simple this bypass was.

No worries admins, Microsoft says that it was only a "Moderate" issue.

I've been researching the Microsoft cloud for almost 7 years now. A few months ago that research resulted in the most impactful vulnerability I will probably ever find: a token validation flaw allowing me to get Global Admin in any Entra ID tenant. Blog: https://t.co/jD6EaGtsn3
