I read this and I'm terrified, the situation seems intractable.

In the python ecosystem alone every cpython install, venv, UV is at risk.

Don't get my started on npm, pnpm, yarn, go, rust.

My current 2026 security posture: stay home and only connect to the internet from a trusted ISP.

The winter is coming.
