For those who haven't seen this trending elsewhere, a popular npm library executed malicious code on victims' computers. To summarize the thread (t...

Somebody in the thread suggested treating ownership changes as a major version bump. That seems worth exploring, although my gut feeling is that the only way it'd really work well is to make it part of the semver standard and have the registry automatically bump and republish on any addition to the collaborator/publisher list.
Yeah but then a smart attacker would just release an innocuous major version and then slip in the malware in the next minor one.
Also it's obvious that people need a way to get paid for working on open-source. Free lucrative startup idea below:
Let's create a service à-la Spotify:
Sounds a bit like tidelift.com/ 🤔
I've seen it beeing used by chalk, vue and babel.

Well let's do more of that :)
Yeah this could lead to a better maintained kind-of stdlib for js.
But it might also lead to an even more fragmented ecosystem, where it is most lucrative to publish a lot of one-liners and hope that a big project will use it somewhere in it's dependency graph.
It would also leave other kinds of packages more or less unpaid. Take for example a cli app. No one will depend on it, while it could have millions of downloads at the same time. On the other hand, that's a different kind of problem as it wouldn't have such an impact on the generell ecosystem and could be targeted by donations, one time payments or something like that.
The revenue split is certainly a tricky question, however at this point it seems obvious that:
When it's easier to buy it people tend to do so. I definitely think it's worth working around that idea.
The problem I see is we're not dealing with people, we're dealing with organizations. Its a bit odd but I don't think a company would decide to pay for such a service.
Also Back Your Stack does the same but offers more piecemeal contributions.
Not entirely related, but I wanted to mention that Python struggles from the same security issues. Most people don't realize that despite PyPI, the Python Package Index, being the primary source for most popular modules, the fact that it's available on PyPI offers no security assurances at all, and any module hosted there is also susceptible to hosting malicious code.
I wonder if methods used to filter malicious JavaScript XSS attacks against web-forms could be similarly employed by a plugin, or other means, to look for specific JS functions or strings, like
eval(), before a package could be imported or used. It might be a good starter project for someone who has been considering learning how to write plugins for VSCode, Atom, etc.The possibility of malicious npm packages was pointed out almost a year ago.
The root of the problem cannot be fixed in imperative paradigms. By definition, if you can tell the effects of any piece of code through static analysis, it's declarative (no side-effects), not imperative. And if you can't identify the effects automatically, you're going to have to read and understand the code all by yourself, which greatly reduces the time saved by using someone else's code.
There's a reason functional programmers keep raving about (safe) composition.
Admittedly, you could have an automated system that analyzes a subset of the code/syntax automatically, rather like the safe language extension in Haskell, which might work for a lot of cases.
Not really a solution to this problem, but more of a damage control thought... Is there a way to run dependencies of dependencies in some kind of a restricted sandbox environment, where HTTP requests and access to DOM are intercepted, and only whitelisted dependencies get that kind of access? Is it possible to create a scope with fake
windowanddocumentobjects for those dependencies, from which they cannot break out?If it's possible I guess webpack or whatever is bundling the JS would have to take care of that sandboxing?
I think there are a lot of facets to this, but I think it would be interesting if there were a crowdsourced auditing/vetting system associated with package ecosystems. Auditing is yet another way people can contribute to open source, and it's something a lot of us are doing anyway. Here's how I imagine it would work:
Individuals or organizations could stand up their own installations of this auditing management tool, so that a user could make sure they sign off on code entering their own system, or a company could make sure new or updated dependencies are audited and use this tool to manage that. Who knows - maybe you could attach a bounty to audit a module (who knows how the auditor would prove they did the work, though)!
Obviously the value of the audit is only as good as much as you trust your auditors, - maybe it would just be pushing things back until things like voting ring attacks pop up around this auditing infrastructure - but it would be a start.
I can imagine an automated audit which might be useful. To ensure that the minified version of a package is the same as the normal version. Setting an easy way for anyone to verify this change sounds straight-forward, although perhaps not easy.
I see a direct parallel between trusting binaries and trusting minified source. For those who are not familiar with Ken Thompson's paper "Reflections on Trusting Trust", I highly recommend reading it:

I don't have any numbers to back this up but I believe that an issue in the JavaScript ecosystem is the lack of a decent standard library.
Because of that you need an external library for pretty much everything you do (left-pad anyone?) and that's adding a lot of potentially compromised dependencies in your tree.
If we could unify this JS ecosystem with a large standard library that can also be progressively polyfilled into older browsers this would be a great way to reduce the attack surface.
I think there is already a company doing that... a node company forgot the name and i think they were bougth by someone.
nodesource.com/ these guys.
I definitely think digitally signed packages would be a good way to go. I think having a central repository for packages may eventually cause issues because considerations like who actually owns the hosted data, who can rightfully access the data, does charging to access the packages violate the licenses, etc? Maybe just a service that doesn't digital signing and authentication, so each module can be checked before being loaded, or create some sort of warning message should the check of the digital signature fails.
