A supply chain attack hit LiteLLM on March 24th.

Two PyPI versions. Six hours. Your AWS keys, SSH keys,
DB passwords, Kubernetes tokens — silently exfiltrated.
You didn't even have to install it directly.
A transitive dependency was enough.

EVERYTHING FROM A TRANSITIVE DEPENDENCY!

The attacker compromised Trivy — LiteLLM's own
CI/CD security scanner — and used it to push
malicious packages to PyPI under a maintainer's account.
v1.82.8 even dropped a persistence file into
site-packages that survives uninstall.
The security tool. Was the attack vector.

Hot take: this isn't an "AI" problem.
ML and deep learning are math. Gradient descent
doesn't steal your secrets.
What steals your secrets is a rushed,
overhyped ecosystem where devs blindly
`pip install` without reading a changelog.
I review every dependency update before I trust it.
It's boring. It works.

I wrote up the full breakdown — what happened,
what was stolen, the uncomfortable pattern behind
incidents like this, and what to do if you're affected.

LiteLLM's supply chain breach in March 2026 compromised credentials via malicious PyPI packages. Here's what happened and why AI middleware deserves more scrutiny.
