GPT-5.5 Instant is more dependable, with significant improvements in factuality, especially in domains where accuracy matters most, like medicine, law, and finance. It’s also stronger across everyday tasks, from analyzing image uploads to answering STEM questions to knowing when web search can help.

next time create efficient backdoor not to get caught

software engineers will notice half a second of latency in something that should be ~instant and will move heaven and earth to fix it, or at least to understand why; and this seems to have blown an operation that had started to install a backdoor on every Debian/Ubuntu SSH server

Confirmed!! Seunghyun Lee (@0x10n) of KAIST Hacking Lab used a UAF to RCE in the renderer on both #Micosoft Edge and #Google Chrome. He earns $85,000 and 9 Master of Pwn points. That also puts us over $1,000,000 for the event! #Pwn2Own

Wow. A bug in the Seaborn data visualization software hid many CD=1 papers, leading Park et al to incorrectly conclude that disruption in science and technology is declining (top histogram), while it is not ( bottom histogram). @VincentGinis

Ouch, could it be, that a scandalous patter of disruptiveness decline be explained by specifics of pre-processing of the data? arxiv.org/abs/2402.14583 what do you think @svalver ?

I've just implemented ChaCha20-Poly1305 in JavaScript, fitting it into 3 tweets. Couldn't make it fit into a single tweet, but I think it's impossible 😅 // Usage: // All parameters are Uint8Array // Nonce should be 12 bytes await encrypt(plaintext, aad, key, nonce)

Elon Musk kind of ruined Twitter for this, but I was reminded of an old challenge: write a modern cipher (encryption) in a single (280 character) Tweet. Can we get authenticated encryption?

It's 779 bytes! I thought a tweet is 260 bytes, so did my best to make it under 780 bytes. Looks I didn't have to though :/

I came across this puzzle at 1AM. At that time, I thought it was a good pre-sleep puzzle, and it kept me up until 11AM when I finally solved it lmao It's very fun, so give it a try: curta.wtf/puzzle/base:5

I wrote the writeup for the ZSafe puzzle at @curta_ctf by @ret2jazzy: hackmd.io/@kjsman/curta-zsaf…

Curta ZSafe Writeup - HackMD

It was 1 AM. I was just meaninglessly scrolling down my X (formerly Twitter) timeline before I go to sleep… and I came accross to this puzzle from Jazzy.

Ok I found the TU Darmstadt paper that initially disclosed the flaws. TL;DR user hashing to implement a (bad) private set intersection protocol, and its trivially vulnerable to brute-force dictionary attacks. Apple has known since 2019! usenix.org/system/files/sec2…
