NPM debug and chalk packages compromised

Hi, yep I got pwned. Sorry everyone, very embarrassing.

More info:

- https://github.com/chalk/chalk/issues/656

- https://github.com/debug-js/debug/issues/1005#issuecomment-3...

Affected packages (at least the ones I know of):

- ansi-styles@6.2.2

- debug@4.4.2 (appears to have been yanked as of 8 Sep 18:09 CEST)

- chalk@5.6.1

- supports-color@10.2.1

- strip-ansi@7.1.1

- ansi-regex@6.2.1

- wrap-ansi@9.0.1

- color-convert@3.1.1

- color-name@2.0.1

- is-arrayish@0.3.3

- slice-ansi@7.1.1

- color@5.0.1

- color-string@2.1.1

- simple-swizzle@0.2.3

- supports-hyperlinks@4.1.1

- has-ansi@6.0.1

- chalk-template@1.1.1

- backslash@0.2.1

It looks and feels a bit like a targeted attack.

Will try to keep this comment updated as long as I can before the edit expires.

Chalk has been published over. The others remain compromised (8 Sep 17:50 CEST).

NPM has yet to get back to me. My NPM account is entirely unreachable; forgot password system does not work. I have no recourse right now but to wait.

Email came from support at npmjs dot help.

Looked legitimate at first glance. Not making excuses, just had a long week and a panicky morning and was just trying to knock something off my list of to-dos. Made the mistake of clicking the link instead of going directly to the site like I normally would (since I was mobile).

Just NPM is affected. Updates to be posted to the `/debug-js` link above.

Again, I'm so sorry.

Sorry to be dumb, but can you expand a bit on "2FA reset email..." so the rest of us know what not to do?

Ignore anything coming from npm you didn't expect. Don't click links, go to the website directly and address it there. That's what I should have done, and didn't because I was in a rush.

Don't do security things when you're not fully awake, too. Lesson learned.

The email was a "2FA update" email telling me it's been 12 months since I updated 2FA. That should have been a red flag but I've seen similarly dumb things coming from well-intentioned sites before. Since npm has historically been in contact about new security enhancements, this didn't smell particularly unbelievable to my nose.

The email went to the npm-specific inbox, which is another way I can verify them. That address can be queried publicly but I don't generally count on spammers to find that one but instead look at git addresses etc

The domain name was `npmjs dot help` which obviously should have caught my eye, and would have if I was a bit more awake.

The actual in-email link matched what I'd expect on npm's actual site, too.

I'm still trying to work out exactly how they got access. They didn't technically get a real 2FA code from the actual, I don't believe. EDIT: Yeah they did, nevermind. Was a TOTP proxy attack, or whatever you'd call it.

Will post a post-mortem when everything is said and done.

I see (I think): they tricked you into entering a TOTP code into their site, which they then proxied to the real names, thereby authenticating as your account. Is that correct?

It only proves that TOTP is useless against phishing.

Every day brings me another reason to ask the question: "Why the hell did they throw away the idea of mutual TLS?". They then went onto invent mobile OTP, HOTP, TOTP, FIDO-U2F and finally came a full cycle by reinventing the same concept, but in a more complex incarnation - Passkeys.

the UI for client side certificates was shit for years. no one particularly cared. passkeys however are... pretty reasonable.

That's just it. If any of the browser vendors put 1% of the work they spent on renewing their visual identity, remodeling their home page, or inventing yet another menu system into slightly easier to use client certificates (and smart cards) this would have been a solved problem two decades ago. All the pieces are in place, every browser has supported this since the birth of SSL, it's just the user interface bits that are missing.

It's nothing short of amazing that nobody worked on this. It's not as if there isn't a need. Everyone with high security requirements (defense, banks etc.) already do this, but this clumsy plugins and (semi-)proprietary software. Instead we get the nth iteration of settings redesigns.
