Earlier this week, an npm supply chain attack.

It’s turn for crates.io, the main public repository for Rust crates (packages).

The phishing e-mail looks like this:

A phishing e-mail: Important: Breach notification regarding crates.io Hi, BurntSushi! We recently discovered that an unauthorized actor had compromised the crates.io infrastructure and accessed a limited amount of user information. The attacker's access was revoked, and we are currently reviewing our security posture. We are currently drafting a blog post to outline the timeline and the steps we took to mitigate this. In the meantime, we strongly suggest you to rotate your login info by signing in here to our internal SSO, which is a temporary fix to ensure that the attacker cannot modify any packages published by you. — Andrew Gallant on BlueSky

And it leads to a GitHub login page that looks like this:

A fake GitHub sign-in page. — Barre on GitHub

Several maintainers received it — the issue is being discussed on GitHub.

The crates.io team has acknowledged the attack and said they’d see if they can do something about it.

No compromised packages have been identified as of yet (Sep 12, 14:10 UTC).

Cracking Electron apps open

I use the draw.io desktop app to make diagrams for my website. I run it on an actual desktop, like Windows or macOS, but the asset pipeline that converts .drawio files, to .pdf, to .svg, and then to .svg again (but smaller) runs on Linux.

So I have a Rust program somewhere that opens headless chromium, and loads just the HTML/JS/CSS part of draw.io I need to render my diagrams, and then use Chromium’s “print to PDF” functionality to save a PDF.
