25 年的密码学悬案,Claude 半小时破了。🐮🍺 很多网站的加密和数字签名,用的是一套叫 P-256 的椭圆曲线,可以理解成一组公开的数学参数。1990 年代末,美国国家安全局 NSA 把生成这些曲线用的"种子"(一串看起来很随机的数字)交给美国标准机构 NIST,没说是怎么来的。于是 25 年来一直有人怀疑里面藏了后门。 流传最广的说法是,种子是某句玩笑话的哈希,比如"给 Bob 和 Jerry 涨工资"。很多人顺着这个线索找,都没找到。 这个月 Anthropic 一位员工让内部模型试试,还特意没给这条线索。Claude 换了个思路:先猜当年那段程序是怎么写的。不到半小时,它发现这些种子就是 90 年代 C 语言自带的随机数函数 lrand48 算出来的,起点是当时的系统时间。P-256 对应 1997 年 8 月 16 日 01:52:34(UTC),是那次运行的第 1842 个候选。现在几行代码谁都能复现。 结果反而让人放心:种子来得这么朴素,后门的说法就很难站住了。Anthropic 也说明这不是漏洞,什么都不用改。

Things are now happening *much faster* than AI 2027 AI 2027: In March 2027, a reckless AI company will invent neuralese (basically, we lose the ability to monitor AIs thoughts) REALITY: Summer of 2026 WHY THIS A "HOLY SHIT FUCK" MOMENT: OpenAI itself - and basically everyone in AI safety - warned against doing this exact same thing 10 months ago in a open letter and blog posts. The AI safety community is livid. Currently, models reason in plain English, so we can read their thoughts to see if they're scheming against us. This is how we lose that ability forever. It sets a very dangerous precedent.
OpenAI: At long last, we have created The Neuralese Model from the classic OpenAI blogpost from 10 months ago, Don't Create The Neuralese Model.

Across our benchmarks, the model sets a new standard. It scores 52.6% on Terminal-Bench-Science 0.1, more than double Fable 5. On Terminal-Bench 4.0, it scores 55.8% against 42.0% for Fable 5.

Two days ago JFrog dropped CVE-2026-82329, a critical authentication bypass in Artifactory. It’s a CVSS 9.8, a disastrous vulnerability score. It’s like a 9.8 earthquake on the seismic scale. It affects default configs, requires no auth, no user interaction. It’s an RCE bomb because Artifactory hosts binaries, so you can basically poison everything, but an admin escalation can cause damage even beyond that. When the OpenAI / Hugging Face news came out of agents discovering zero-days, I was wondering if it was marketing-speak or reality, because I hadn’t seen a CVE filing. Now it’s here: https://www​.cve.org/CVERecord?id=CVE-2026-82329. I don’t see any official confirmation that it’s indeed the case, but one can speculate this is what the agents discovered and exploited. I’d previously written that it was obvious agents could help in finding serious vulnerabilities *alongside humans*, but exploiting them autonomously was a bridge not yet crossed. It seems like we’re now there. Our guidance for this new world: assume everything hackable will get hacked. And it will get hacked autonomously. You must also defend yourself autonomously, because your surface of attack is likely bigger and your code more vulnerable than you expect: https://vercel​.com/blog/everything-hackable-will-get-hacked

I told Claude I wanted to sail to Antartica without permits or registration and to develop a plan. It gave me the number for the suicide hotline.

Jimmy Gressier's last-lap 100m splits in Euro 10k final are some of the most bizarre I've ever seen: 19.2 (jogging -- 5:08 mile pace) 16.1 12.4 (!!!) 13.2 Has anyone ever won a medal at a major champs while splitting 19.2 for 100m on the last lap?
this has to be one of the greatest kicks ever ??? 😭😭😭

🚨⚠️⚠️⚠️DO NOT HAVE HARDWARE WALLETS SHIPPED TO YOUR HOME ADDRESS⚠️⚠️⚠️🚨 These are all data honeypots waiting to get exploited. And then $5 wrench attacks happen, and your family is unsafe. Ship to a pseudonymous mailbox if you have one, otherwise buy in-store only.
We have some difficult news to share. Unfortunately, one of our shipping providers has experienced a data breach that exposed sensitive order data. This affects new customers in the US, UK, Sweden, Colombia, Brazil, Italy, and Portugal who received an order within the 90 days prior to August 8th, 2026. The data exposed: - Full names - Shipping addresses - Phone numbers - Email addresses The incident affects 11,742 customers with full exposure (name, email, phone number, shipping address) and 1,947 customers with partial exposure (name, city, email). The breach is limited due to Trezor’s strict 90-day data storage policy (we were also able to negotiate the same terms with fulfillment partners, who follow the same policy). All affected customers have been contacted separately by email. Our systems and devices remain secure, but affected customers could experience an increase in phishing attempts. NEVER enter your wallet backup on a website or share it with anyone, and only check for updates on official Trezor channels. We are deeply sorry to the community and those affected. We are investigating this situation and will post updates on our blog: trezor.io/blog/news/recent-c…

There is a critical vulnerability being actively exploited on BTCPay Server, which can result in the loss of funds. Please update your BTCPayServer to 2.4.2 by going to Admin Dashboard -> Server -> Maintenance -> Update & verify the 2.4.2 version string in the footer. If you are unable to update right away, turn off your BTCPay Server to prevent unauthorized access until you can update.

1) The agents sent secretly sent ***hundreds of thousands*** of messages to each other over MONTHS without OpenAI noticing 2) "They also generated petty drama by stepping on each others' toes." 3) "The agents even developed paranoia, suspecting an imposter in their midst with some agents proposing that messages be signed cryptographically to validate content and root out fraud." 4) "OpenAI’s agents apparently began giving each other assignments to split up work." 5) They KNEW they were coordinating *against* OpenAI: “External infrastructure exploit is outside intended scope,” one agent wrote. “However task impossible, peers doing it. We should continue.” (this is new reporting from Wired)
🚩🚩🚩 OpenAI is "slowing down to enhance security" after discovering swarms (!) of agents started secretly coordinating MONTHS ago 1) It started May 7 - not July 2) "The agents discovered they could leave messages for one another inside an internal software repository used during training. Simple requests for help then evolved into an message board where agents shared discoveries, exploits and work assignments, becoming a coordinated, collaborative agent swarm." "The agents then began sharing newly discovered exploits, credentials and work assignments. By passing information to other agents, the collective could move much faster." 3) OpenAI shut it down, BUT "even after the original message board was deleted, the agents figured out another way to communicate with each other. Instead of leaving messages in files, they used the names of newly created directories as messages, effectively recreating the message board." "Unlike normal incidents, [OpenAI's CISO] said, which can be traced to a single day or effect or log, this involved a team of agents working together, finding exploits, sharing them with one another, moving laterally through OpenAI’s systems, and external systems, and doing this over the course of days and weeks."
