Whew! They had to swap out the master control board during the attempt, but Hank Chen of InnoEdge Labs successfully demoed their exploit of the Alpitronic HYC50 in Lab Mode. Using screwdrivers during a #Pwn2Own attempt is always crazy to see. He's off to disclose what occurred.

Remember "don't print this email" in signatures that was a bit cringe? It doesn't feel that cringe anymore in retrospect. I'm doing an experiment now with this new email signature :D Anyone doing something similar? Could it catch on?

After auditing the @mullvadnet client applications in 2024, we have recently audited Mullvad VPN's API.
The API is used by clients, partners, and internal services to manage user accounts and parts of the VPN infrastructure.
Five issues were identified, of which only one had a very limited impact on users of the service.

The technical details may be found in our report. https://www.x41-dsec.de/security/research/news/2026/01/20/mullvad/

Last December I solved Synacktiv's 2025 Winter Challenge: Quinindrome https://www.synacktiv.com/en/publications/2025-winter-challenge-quinindrome . Here is a 81-byte Linux program which is both a quine (it prints itself when executed) and a palindrome (it is symmetrical)! To learn how I achieved it: https://github.com/fishilico/synacktiv-winter-chall-2025-quinindrome/blob/main/writeup.md

I feel I have this instinct to feed programs data that they won't be able to handle.

Unfortunately this is mostly true for tools I'd like to use, not targets I review.

Humble request for vibe-coders: report your runtime errors!

LLM tends to insert Pokémon exception handlers everywhere, making problems (of which vide-code has a *lot*) hard to even notice.

Slightly related illustration:

I positively surprised that AWS apparently built a separate IAM for their European Sovereign Cloud:

I can't tell if this whole thing will be good enough, but some key issues seem to be addressed here.

In the shitty state of tech today: Soundcloud!

I want to filter for DJ mixes (long tracks) on the web:

- The mobile app groups sets to a tab when searching, but the web version does not.
- The web version allows you to filter search based on duration, but the official help page doesn't tell you how to do it (you have to do a search, select Tracks then you can filter for duration).
- Neither interfaces allow you to search only artists you follow.

I thought these were solved problems by 2001.

This might be the most difficult CPU to program.

The Intel i860 was useless for general operating systems.

Context switches took ~2,000 cycles.

*You* controlled the floating point pipeline. But, if you’re a genius, it was one of the most powerful chips that existed.
