Cook’s “How complex systems fail” is the most personally impactful paper I have ever read, and yet I’m convinced that it would never have been accepted for publication in a peer-reviewed journal.

📢 Next week is #TROOPERS24 week! We will celebrate 15 years of making the world a safer place and are looking forward to all of you. See you in #Heidelberg. 🥳

A few years ago, a kid mourning his dad handed me over 300 DVDs his dad had made of local bands in his London Suburb in the 2010s before passing on. He didn't know what do with them. I did. All of them are up at Internet Archive, hundreds of hours of cover bands playing in a bar, and now, thanks to a volunteer, Ducky, we have them all with dates and descriptions, where known. Enjoy.

Fuzzing can do more than find memory corruption vulnerabilities. With the right invariants, it can catch runtime errors and logical issues, as demonstrated by our custom testing harness for Fuel Labs. https://blog.trailofbits.com/2024/06/17/finding-mispriced-opcodes-with-fuzzing/

Abusing title reporting and tmux integration in iTerm2 for code execution (CVE-2024-38396) https://vin01.github.io/piptagole/escape-sequences/iterm2/rce/2024/06/16/iterm2-rce-window-title-tmux-integration.html

I've done it! After literal months of work, I've finally finished my (rather long) blog post about how AES-GCM works and how it's security guarantees can be completely broken when a nonce is reused:

https://frereit.de/aes_gcm/

It includes more than 10 interactive widgets for you to try out AES-GCM, GHASH and the nonce reuse attack right in your browser! (Powered by #RustLang and #WASM )

If you're interested in #cryptography , #math (or #maths ) or #infosec you might find it interesting.

If you do read it, I'm all ears for feedback and criticism!

Just published age v1.2.0 ✨

Minor release:

• binaries built with Go 1.22.4
• plugin client API
• CLI edge case fixes
• RecipientWithLabels to make auth'd or post-quantum recipients

Very happy about the last point, it was the last hardcoded thing about scrypt recipients.

Look at that! I got a new domain name.

~ Let's make RAM at home, thread #1 ~

In this thread: successful experiment with factory-made ferrite core memory (1 bit for now!), a brief explanation of the experiment, and failed attempts at making a core (so you wouldn't have to try it)

🧵 go~

I became into toy computers after I got my hands on a wonderful Sumikko Gurashi computer (and started to believe that similarly designed machines can be an answer to our cold heartless world).

I have a few vintage vTech precomputers that run BASIC and have decent IO capabilities (a serial or a parallel port at the very least), but I was curious whether newer toy computers has anything similar.

The exhibit we have here is vTech Media Desktop, a toy computer from around 2010. Its original RPP was about $100, but after a short while slashed to $25. The computer has a non-backlit ~64x48 pixel LCD, two mid-sized speakers to play high-quality digital samples and polyphonic MIDI, a membrane keyboard and a ball mouse.

There is a mini-USB port on the back that switches computer into "Sync" mode. The device presents itself as a 16MB USB stick with 512KB free, and mirrors there the contents of 512KB SPI Flash it has on board.

With the right software (which has vanished from the Internet), new apps can be added.
