A lot of this seems to be a reminder that the CommonJS module format should just be left to die already. Not that you can't pull similar tricks with `await import()` in ESM, but you can't easily grep an entire dependency for dynamic `require()` half as easily as you can can `grep import\s*\(` for dynamic import and analysis tools for static `import` keyword are easy to use/build rather than no such thing for CommonJS.
Someone thought I was joking when I said I always check JSR before NPM now, because I trust ESM so much more than CommonJS.
Why in the world would that specific 3x3 matrix be a trigger for an attack? Are they trying to find someone doing some particular kind of numerical analysis?
Presumably it's so it can be used as a subdependency for setting up an attack in a popular, legitimate package, e.g. via a pull request. The code in the legitimate package would not arouse suspicion at all.
I would assume it’s actually so they can allow it to spread before it gets activated. Then do something that affects the entire chain of package dependencies
This matrix is not a condition, it’s a key. JSON.stringify with it’s data goes to the scrypt as a password and that creates an AES-256-GCM key. There is no if, every other input won’t decrypt. That’s why no one will get payload from the package without knowing the exact input.
Does the FBI or any other law-enforcement office follow up on these backdoors? Is this considered a crime, or even conspiracy to commit a crime, or is it only the act of using the backdoor that's a crime?
My strategy of not using dependencies at all seems to be getting stronger everyday.
Also no LLM generated skipping this hypetrain completely. Just hand written code I can personally vouch for. Code in exchange for cash, this is professional business, Boss.

So, where do you draw the line? Do you accept having an OS? Because that is a huge dependency. So I assume you run directly on BIOS or UEFI? But even those are fairly sizable on modern systems.
Yeah lots of weird emphasis on things a human wouldn't care about. And emphasis on what it isn't, rather than what it is. It's not Y, it's X. And there are two files!!!

The NPM package not named in the clickbait-y post title is “mathmain@1.0.0”, for those who run into this particular site obstacle; the later packages also named are “mathsbase” and “math-universe”. (EDIT: I see the submission title has been updated, so that’s my complaint addressed, thanks mods!)
Safedep, if you’re reading this, perhaps you should reconsider having that site feature applied to your post — or if it’s something you enabled in, say, Cloudflare, perhaps file a support ticket noting that their email protection is hiding package version strings.
Probably Cloudflare. For me it shows the package name rather than a redaction. But from memory, Cloudflare email protection redacts it that way in the HTML and then adds a little JS to put it back in which might also do some kind of check to see if it thinks you are a real user before unredacting it.

I can also see that it's still up in NPM without any warning of any kind: - https://www.npmjs.com/package/mathmain
But the Github repo for the package and the author are down: - https://github.com/allendev12 - https://github.com/allendev12/mathmain
