Show HN: Computer Police – block malicious NPM/pip installs locally

[kannthu]

A couple of months ago, our team got hit by the first version of Shai-Hulud through a random `npm install`. We didn't catch it until it was too late.

I built Computer Police for our team to never be in this situation again.

It's designed to block that earlier. It runs a local registry proxy between your package manager and npm/PyPI, and stops confirmed-malicious packages before they touch disk.

It's deliberately narrow: malware only, no CVE scanning, no heuristics, no telemetry, no root, and removable with one command. Works locally, in CI, and in agent sandboxes.

Interesting. How long does it usually take for an attack to be identified and catalogued at OSV? Should this be used together with minimum release date?

I don't have the exact number for you, but what I observed was that it took a couple of hours for npm to remove some of the packages this week, even though an advisory was published
