Alright, it's official! 💰

@matthew_d_green and I bet on what will break first, ML-KEM-768 or X25519. The loser donates to a 501(c)(3) picked by the winner.

If you have an opinion on quantum computers or lattices, you can join with a side bet. Just submit a PR!

Update on Valve sponsored work in Q1 2026 - Arch-dev-public - lists.archlinux.org

Two papers came out last week that suggest classical asymmetric cryptography might indeed be broken by quantum computers in just a few years.

That means we need to ship post-quantum crypto now, with the tools we have: ML-KEM and ML-DSA. I didn't think PQ auth was so urgent until recently.

A Cryptography Engineer’s Perspective on Quantum Computing Timelines

The risk that cryptographically-relevant quantum computers materialize within the next few years is now high enough to be dispositive, unfortunately.

So Anthropic employees are using Claude Code to contribute AI-generated code to open source repositories and hiding the fact using their own internal “undercover mode”.

Totally trustworthy people.

(Any open source project that at the very least requires disclosure of AI-authored contributions should immediately ban Anthropic employees on principle.)

If you replace all the innerHTML with setHTML, you will be free from XSS and other injection attacks. Goodbye innerHTML, Hello setHTML

Goodbye innerHTML, Hello setHTML: Stronger XSS Protection in Firefox 148 – Mozilla Hacks - the Web developer blog

Cross-site scripting (XSS) remains one of the most prevalent vulnerabilities on the web. The new standardized Sanitizer API provides a straightforward way for web developers to sanitize untrusted HTML before inserting it into the DOM. Firefox 148 is the first browser to ship this standardized security enhancing API, advancing a safer web for everyone. We expect other browsers to follow soon.

We really can do anything

Today in InfoSec Job Security News:

I was looking into an obvious ../.. vulnerability introduced into a major web framework today, and it was committed by username Claude on GitHub. Vibe coded, basically.

So I started looking through Claude commits on GitHub, there’s over 2m of them and it’s about 5% of all open source code this month.

As I looked through the code I saw the same class of vulns being introduced over, and over, again - several a minute.
