It isn't victim blaming. People like you make it impossible to avoid attacks like these because you have no appetite for a better security model. I run npm under bubblewrap because npm has a culture of high risk; of using too many dependencies from untrusted authors. But being scrupulous and responsible is a cost I pay with my time and attention. But it is important because if I run some untrusted code and am comprom…

No, you are the problem because you have a higher expectation than reality. People shouldn't have to run npm in containers. You're over simplifying with one case where you have found one solution while ignoring the identical problems elsewhere. You are preventing us from looking at other solutions because you think the one you have is enough and works for everyone.

NPM post-install scripts considered harmful. There has to be a tool that allows you (or an AI) to easily review post-install scripts before you install the package.

Could an attacker confuse a reviewing AI by adding a comment to their install script?

> one would proritize trying to fix things upstream closer to the root

One should prioritize fixing things one is responsible for. If you make a commitment to protect your user’s data, then you take responsibility for the tools you use, and how you use them.

Whether or not you – or someone else – should fix those tools upstream, is a separate issue to be solved later. First solve the problems that are your responsibility. Then worry about everyone else.

The npm ecosystem has many security issues but they are all mitigatable.

We don't have a clear explanation of the destructive behavior, right? It looks like it had no real purpose, and there were much more effective ways of destroying their repos. Very script kiddie-like, which does not really fit the main complexity of the virus. Very surprising.

It hides the malware's trail, and disguises which keys were leaked, making rotation harder

The socket.dev deconstruction of the worm (https://socket.dev/blog/shai-hulud-strikes-again-v2) suggests that the destructive actions on GitHub were not part of the malware itself.

I can’t speak for majormajor but I thought the language was kind of funny. “The problem is an ecosystem that allows packages to run arbitrary code silently” is an odd statement because for many people that’s kind of what a package manager does.

> No, your security failure is that you use a package manager that allows third-parties push arbitrary code into your product with no oversight. Could you explain how you'd design a package manager that does not allow that? As far as I understand the moment you use third party code you have to trust to some extent the code that you will run.

But like, isn't that actually the core of the problem? People choose to blindly trust some random 3rd parties - isn't exploiting this trust seems to be inevitable and predictable outcome?

You can use keyring/keychain with credential_process although it's only a minor shift in security from "being able to read from the fs" to "being able to execute a binary"

> As I understand it, no mainstream desktop OS provides the capabilities to, for example, protect a user's browser cookies from a malicious tool launched by that user. macOS sandboxing has been used for this kind of thing for years. Open a terminal window on a new Mac and trying to open the user’s photo library, Desktop, iCloud documents, etc. will trigger a permissions prompt.

Interesting, it's a few years since I've used a Mac. Descriptions of this stuff online are pretty confusing. Apparently there's an "App Sandbox" and also "Transparency Consent and Control" - I assume from your mention of the photo library describing the latter? How does this protection interact with IDEs? For some operations conducted in an IDE, like checking out code and collecting dependencies the user grants the s…

They added sandboxing in the 2000s, which does mandatory access control (e.g. you can write a rule that Firefox.app can’t access ~/Library/Keychains) and expanded it with containers (not OCI) which standardize the layout starting with the App Store so they all follow common restrictions for what they can access and where they store different classes of data. Those policies are inherited by child processes (e.g. your Terminal.app permissions apply to CLI tools you run in its windows but not something you start by logging in via SSH) so much of the effort has been standardizing the UX – don’t access photos directly, use the system picker which allows the user to select subsets, etc.

https://developer.apple.com/documentation/security/app-sandb...

So the answer to that question depends on what permissions the IDE has asked for and been granted. It’s likely that the first time you opened a shell inside the IDE you’d get promoted for permission to access protected locations the first time you ran a command which did something protected, but they could ask for something like full disk access at install time to avoid many prompts.

> have been reviewed by multiple security org/researchers I imagine reviewing all the code for all the packages for all the published versions gets really expensive. Who's paying for this?

Microsoft has a 3.5 trillion dollar market cap. I guess they can pay for it?
