I know people have opinions about cooldowns, but they would have saved you from axios, tanstack, and many other recent npm supply chain attacks. If you have Artifactory / Nexus, you probably already have cooldowns, but it's easy to set up if you don't.

Why cooldowns? Most npm (or pypi) compromises were taken down within hours, cooldowns simply mean - ignore any package with release date younger than N days (1 day can work, 3 days is ok, 7 days is a bit of an overkill but works too)

How to set them up?

- use latest pnpm, they added 1 day cooldown by default https://pnpm.io/supply-chain-security

- or if you want a one click fix, use https://depsguard.com (cli that adds cooldowns + other recommended settings to npm, pnpm, yarn, bun, uv, dependabot and, I’m the maintainer)

- or use https://cooldowns.dev which is more focused on, well, cooldowns, with also a script to help set it up locally

All are open source / free.

If you know how to edit your ~/.npmrc etc, you don't really need any of them, but if you have a loved one who just needs a one click fix, these can likely save them from the next attack.

Caveat - if you need to patch a new critical CVE, you need to bypass the cooldown, but each of them have a way to do so. In the past few weeks, while I don't have hard numbers, it seems more risk has come from Software Supply Chain attacks (malicious versions pushed) than from new zero day CVEs (even in the age of Mythos driven vulnerability discovery)
