As a user of npm-hosted packages in my own projects, I'm not really sure what to do to protect myself. It's not feasible for me to audit every single one of my dependencies, and every one of my dependencies' dependencies, and so on. Even if I had the time to do that, I'm not a typescript/javascript expert, and I'm certain there are a lot of obfuscated things that an attacker could do that I wouldn't realize was embedded malware.

One thing I was thinking of was sort of a "delayed" mode to updating my own dependencies. The idea is that when I want to update my dependencies, instead of updating to the absolute latest version available of everything, it updates to versions that were released no more than some configurable amount of time ago. As a maintainer, I could decide that a package that's been out in the wild for at least 6 weeks is less likely to have unnoticed malware in it than one that was released just yesterday.

Obviously this is not a perfect fix, as there's no guarantee that the delay time I specify is enough for any particular package. And I'd want the tool to present me with options sometimes: e.g. if my current version of a dep has a vulnerability, and the fix for it came out a few days ago, I might choose to update to it (better eliminate the known vulnerability than refuse to update for fear of an unknown one) rather than wait until it's older than my threshold.

Personally, I go further than this and just never update dependencies unless the dependency has a bug that affects my usage of it. Vulnerabilities are included.

It is insane to me how many developers update dependencies in a project regularly. You should almost never be updating dependencies, when you do it should be because it fixes a bug (including a security issue) that you have in your project, or a new feature that you need to use.

The only time this philosophy has bitten me was in an older project where I had to convince a PM who built some node project on their machine that the vulnerability warnings were not actually issues that affected our project.

Edit: because I don't want to reply to three things with the same comment - what are you using for dependencies where a) you require frequent updates and b) those updates are really hard?

Like for example, I've avoided updating node dependencies that have "vulnerabilities" because I know the vuln doesn't affect me. Rarely do I need to update to support new features because the dependency I pick has the features I need when I choose to use it (and if it only supports partial usage, you write it yourself!). If I see that a dependency frequently has bugs or breakages across updates then I stop using it, or freeze my usage of it.

counterpoint, if the runtime itself (nodejs) has a critical issue, you haven't updated for years, you're on an end-of-life version, and you cannot upgrade because you have dependencies that do not support the new version of the runtime, you're in for a painful day. The argument for updating often is that when you -are- exposed to a vulnerability that you need a fix for, it's a much smaller project to revert or patch that single issue.

Otherwise, I agree with the sentiment that too many people try to update the world too often. Keeping up with runtime updates as often as possible (node.js is more trusted than any given NPM module) and updating only when dependencies are no longer compatible is a better middle ground.

The same logic you used for runtimes also applies to libraries. Vulnerabilities are found in popular JS libraries all the time. The surface area is, of course, smaller than that of a runtime like Node.js, but there is still lots of potential for security issues with out-of-date libraries.

There really is no good solution other than to reduce the surface area for vulnerabilities by reducing the total amount of code you depend on (including third-party code). In practice, this means using as few dependencies as possible. If you only use one or two functions from lodash or some other helper library, you're probably better off writing or pulling in those functions directly instead.
