⚠️ Everyone asking me about the GitHub hack is asking the wrong question.
A friend pinged me yesterday: "GitHub got hacked, what do I do?" Their account is fine. GitHub itself was breached on May 19. Hackers stole about 3,800 internal repositories from GitHub's own corporate systems. Customer accounts, customer repos, organizations, enterprises. All confirmed unaffected. But that's the wrong thing to be worried about. The interesting part is HOW GitHub got breached. A GitHub employee installed a poisoned 𝗩𝗶𝘀𝘂𝗮𝗹 𝗦𝘁𝘂𝗱𝗶𝗼 𝗖𝗼𝗱𝗲 𝗲𝘅𝘁𝗲𝗻𝘀𝗶𝗼𝗻 called Nx Console. The malicious version (18.95.0) was published May 18, 2026, sat in the marketplace, and anyone who installed or auto-updated to it during that window got compromised. The same group, TeamPCP, has now expanded the campaign into PyPI, the Python package registry. They backdoored legitimate releases of LiteLLM (a popular AI gateway library) and Telnyx's official SDK. So the real question isn't "was my GitHub account hacked." It's "did I touch any of the compromised software on my own machine?" If you installed Nx Console between May 18 and when it was pulled, your laptop may be compromised. If you have a Python project using LiteLLM or Telnyx and you ran a fresh install in that window, your laptop may be compromised. Your machine got hit, not GitHub's platform. This is the shape of modern attacks. Supply chain. They don't break in through the front door. They poison a dependency you trust and wait for you to install it. The breach at GitHub is downstream of that. Same attacker, same campaign, different victim.

It will ask what operating system you're on, then give you the exact commands to run. ----- PROMPT START ----- I want to check if my computer was affected by the May 2026 supply chain attack connected to the GitHub breach.
