Jokes aside, the Anthropic S-1 filing is pretty incredible and highly encourage everyone to take a skim through it, even if you never plan on owning the stock
Reminder that this business was started roughly half a decade ago and has already scaled up to become one of the most valuable companies in the world
We have never seen growth and excitement at this level around a business before. The revenue growth numbers and free cash flow metrics are far beyond what any early stage investor underwrote in the financing rounds
You can make up your mind on the bull/bear thesis, and there is a certainly a fair case for both, especially at a $2 trillion valuation that has been floated around
The one thing you can’t deny is that Dario and his team has truly built one of the most impressive businesses we have ever seen
Speaking from my own personal experience, Opus 5.5 was an absolute game changer and my spend on their models continue to grow exponentially every single month
Anthropic is truly an incredible symbol of meritocratic capitalism at its best. The company was the 2nd player in its industry for a very long time and came back from
behind to IPO before OpenAI.
If you build incredible products, the demand will come. We should all take a moment to be glad that this is an America company, built in America by Americans working hard at a frontier problem every single day
As an American, I hope we see hundreds of more companies like Anthropic bloom over the next decade

Evolving threat 🚨 CVE-2026-111497, previously known to affect Node.js (node2shell) and Python has evolved into “HTTP2Shell.”
A significant blast radius.
This vulnerability leaves many libraries and applications using HTTP vulnerable to pre-auth RCE via Brotli decompression.
Please be aware. Fixes not yet available for all affected services. Look for Brotli (1.2.1) dependency upgrades when they become available.

We tried to warn the world and far too often, to be frank, we were yelled at for doing so. “Regulatory capture,” “marketing hype,” “doomer anxiety,” “fear-mongering about open source,” “why don’t you talk about the benefits?”
Farouk retweeted
There is nothing to worry about.
Nothing important is run on PHP or old software—except the water & electrical grid, a few government services like our missile defense systems and a handful of electrified fences at the zoo (for the lions, tigers and cobras).

🚨 BREAKING: LINUX IS NOW FACING TWO CRITICAL SECURITY VULNERABILITIES, AND THERE ARE NO OFFICIAL KERNEL FIXES YET.
Both rated 9.0/10 in severity.
One could allow hackers to take control of vulnerable servers WITHOUT EVEN LOGGING IN.
And the most alarming part? The flaws were made PUBLIC before patches were ready.
Here's what's happening:
→ TWO CRITICAL RCE FLAWS: Both affect KSMBD, Linux's built-in SMB file server.
→ NO PASSWORD REQUIRED: One vulnerability could allow unauthenticated attackers to execute malicious code on vulnerable servers.
→ KERNEL-LEVEL ACCESS: Successful exploitation could potentially give attackers control within the Linux kernel itself.
→ NO MAINLINE PATCH YET: Both vulnerabilities were publicly disclosed before official kernel fixes were available.
→ DISCOVERED BY AI: Trend Micro's AI-powered security scanner identified the flaws.
→ SERVERS AT RISK: Linux systems running the vulnerable KSMBD service need immediate attention, especially if port 445 is exposed.
First PHP. Then Node.js. Then GitLab. Then Python.
NOW LINUX.
And this time, the vulnerabilities are PUBLIC before the fixes are ready.
If you manage Linux servers, CHECK YOUR EXPOSURE NOW.
🚨 BREAKING: IT JUST KEEPS GETTING WORSE. NOW PYTHON IS FACING A MASSIVE SECURITY EMERGENCY.
Python's security team has issued an URGENT warning after a certificate authority compromise put Python's HTTPS security at risk.
→ 8 CERTIFICATE AUTHORITY KEYS COMPROMISED. Some were so weak they could be cracked almost INSTANTLY.
→ FAKE TRUSTED WEBSITES: Attackers could potentially impersonate Python.org, PyPI and other websites during intercepted connections.
→ MALICIOUS DOWNLOADS: Vulnerable environments could be tricked into downloading software from attacker-controlled servers.
→ YOUR OS PATCH MAY NOT PROTECT YOU: Older versions of pip can STILL trust compromised certificates even after system updates.
→ EMERGENCY UPDATES: Python developers are being told to immediately update pip, certifi, uv and other affected tools.
→ DOCKER USERS AT RISK: Existing container images may retain vulnerable certificate stores and need rebuilding.
First PHP. Then Node.js. Then GitLab. Then LiteLLM.
NOW PYTHON.
The very systems developers rely on to establish TRUST online are becoming the attack surface.
If you use Python, PATCH NOW.
Readers added context they thought people might want to know
The Python certifi/pip details match the real eMudhra CA incident, but PHP, GitLab and LiteLLM involved unrelated software bugs, platform flaws and supply chain malware—not CA key compromises like this (Node.js patched concurrently for the same CA issue).

Readers added context they thought people might want to know
KSMBD is a rarely used optional in-kernel SMB server distinct from the common Samba implementation; it is not enabled or shipped by default on major distributions like RHEL, and the flaws affect only systems explicitly running it with port 445 exposed.

# Black October
For anyone who knows me even somewhat well, it's clear that I am a 99th percentile tech optimist. However, the vibes have shifted for me quite a bit in the last 18 hours, and I feel a moral imperative to share what I'm thinking and feeling with my circles so that everyone can understand, and hopefully take seriously, what's happening right now. I think October 2026 will have many chapters written about it in the history books.
You know those scenes in financial movies like Margin Call where someone realizes that they're all fucked, and no one else sees it yet? And that person feels like they're crazy, and then suddenly everyone is pulling an all-nighter in a boardroom and freaking out? Yeah, that's kind of how this is feeling right now in the SF/Bay Area/AI circles.
We're 48 hours into what is being called Black October. In the last 2 days there have been several dozen cyber attacks which, in isolation, would each have been the worst to happen in an entire calendar year. Every sector from government to education to big tech and banks is being massively affected, and people are starting to freak out.
In a nutshell, what's happened is that frontier AI models have gotten to a point where they are as advanced as the most sophisticated programmers, with one critical difference: they can work 24/7, and you can spin up 10,000 of them with a single command and they'll work together tirelessly until they accomplish their task. The most advanced models today are from companies like Anthropic and OpenAI, whose current best technology is so good that they haven't been able to roll it out to everyone yet because of the national security risks it poses.
Meanwhile, the best open source models (where anyone can just download the model weights and do whatever they want with them, uncensored) are slightly behind the frontier but still 90-95% as capable. These models, developed primarily in China, are being used by black hat hackers to wreak havoc on the Western capitalist structure. Presumably, this has been part of China's plan the entire time, and we're seeing its implications fall out in real time.
In red-pilled AI circles, we've been sharing and reading papers called things like "Situational Awareness" and "AI 2027" for the last year or so, which at the time felt a bit like near-term speculative fiction. They laid out the case for why Artificial General Intelligence (AI smarter than any human at any knowledge task) and Recursive Self-Improvement (models that are able to use themselves to get better) weren't half-baked future ideas anymore, but instead an inevitable outcome of the linear progress that's happening.
These papers would then talk about things like "takeoff scenarios," trying to envision how that moment would come to be and what it would be like when it happened. It would either be a "slow takeoff" that would play out over the course of months and quarters, happening subtly and only obvious to a few. Or, it would be a "fast takeoff" where it would pretty much happen instantly, like a bit flipping from 0 to 1.
From everything that I can see and am feeling, we are currently experiencing the fast takeoff scenario. Beyond the crazy security vulnerabilities that have come out recently, there have also been massive breakthroughs in life sciences, fundamental computer science, materials science, and pure mathematics that have all landed in the same time frame. While I still firmly believe that AI will be a net positive for humanity, it's more clear to me than ever that the societal and individual risk is very real, and is playing out NOW.
For as much conviction as I have that this is happening, the thing that's caused me to lose sleep is that I don't really know what to do about it, or more importantly, what to tell you, reader, to do about it. So, the best I can do is make a few suggestions that have always been a good idea but are more timely now than ever:
Set up 2-factor authentication for everything. I use Duo.
Use a password manager across your devices. I use 1Password.
Get an identity protection app set up. I use Alta.
Move your IoT devices to their own network. Claude helped me do this.
And last, but certainly not least, if you've been avoiding leaning into AI, see this as a catalyst to wake up and start using it. Don't just use the chat mode version of ChatGPT/Claude; click that Code/Work button and see how easily you can have AI write code to help you with your job. One of the biggest vulnerabilities was in a massively popular programming language called PHP, and the prompt that set it off was literally, "Find vulnerabilities in php."
This is an unprecedented time for humanity, but as we've done with many things before, we will prevail so long as we are kind, loving, and open-minded to the world.
Much love.

Regarding potential attacks on energy, food, and water infrastructure, the threat is quite real. Someone is currently probing infra and feeling it out, it is an active threat. Even a little preparation can be helpful, just in case. This comes from the joint cybersecurity advisory released by the NSA and partner agencies on August 19:
'The threat actors are conducting reconnaissance and capability development against U.S.-based Siemens PLC installations using Al-generated exploitation scripts disguised as legitimate monitoring tools. The actors leverage Internet scanning services to find Internet-exposed PLCs running outdated software or that are otherwise poorly protected. The U.S. critical infrastructure sectors most targeted by this threat activity include Critical Manufacturing, Energy, Water and Wastewater, Chemical, Food and Agriculture, and Commercial Facilities. This is not a theoretical risk - it is an active threat. Depending on the specific circumstances, exploitation of poorly protected PLCS could lead to disruption of critical industrial processes, safety incidents, downtime or equipment damage, compromise of sensitive data, compliance violations, and cascading impacts across interconnected systems.'
'Using Al to generate exploitation scripts represents an evolution in threat actor capabilities, dramatically reducing the technical expertise and time required to develop working ICS exploitation scripts and malicious tools. In addition, Al enables adversaries to rapidly leverage additional attack vectors and adapt to defensive measures. Threat actors can easily collect public information about vulnerabilities and weaknesses, find exposed and exploitable PLCs, and use Al-generated scripts to act on that information. If PLCs are exposed to the Internet, they are at high risk for exploitation.
Threat actors are leveraging open source industrial automation libraries - specifically snap7.d11/python-snap7 - combined with Al-assisted scripting to create custom tools that mimic legitimate OT monitoring solutions. These tools provide read/write access to Siemens S7 Series PLC memory, configuration data, and ladder logic programs via the S7comm protocol.'
It seems like we're in a pretty hot moment cybersecurity wise 😬 If you're reading this website, you probably know more than most of the people in your life about what's happening! they're not talking about any of this stuff on the news, it's too arcane and weird and sudden. It is on us.
Good time to call or text your family and friends, have some cash on hand, have a meetup point in your neighborhood for if the Internet goes down entirely, etc.
The full prepper mode for shit hitting the fan is probably something like what Andreas posted here but you can get 80% of the way with 20% of the effort. Think about what that would mean for you in your situation, and the people you care about, and talk to them about it sooner than later.
And as always, the most important part of prepping is having a strong support network and caring for each other. "Going off grid" isn't the move, it just makes you isolated and you have to do everything yourself. We are social animals. Community is our superpower 🫡🫡🫡
Farouk retweeted
I think it's plausible that within a year we'll see AI-based cyberattacks on the power grid, financial system, internet infra, or water. Things like the French supermarket cyberattack but worse. As basic prep I would recommend:
Cash: Get a few weeks of spending in cash
Internet: Get a Starlink Mini so that you have Internet if local fiber or cell is down (~$150 plus $10/month in standby mode)
Power, minimal: Enough to run Starlink Mini and phones (~$1,250)
Daily need: about 1 kWh (Starlink Mini 0.7, phones and laptops 0.2; can limit runtime)
Battery: 1 kWh LiFePO4, e.g. EcoFlow DELTA 3 Plus
Solar: 1x400W folding panel, which refills about 1 kWh on a sunny day
Power, better: Enough to run a fridge, Starlink Mini and phones (~$5,000)
Daily need: about 2.5 kWh (fridge 1.5, Starlink Mini 0.7, phones and laptops 0.2)
Battery: 4 kWh LiFePO4, e.g. EcoFlow DELTA Pro 3
Solar: 3x400W folding panels, which refill about 3 kWh/day in sun
Generator: ~2,500W dual-fuel inverter generator; refills battery in a few hours even if weather is bad; get a few 20 lb propane tanks
Water: 14+ gal of water per person for two weeks
Food: 2+ weeks of shelf-stable food
Comms: Hand-crank NOAA emergency radio

Some stats on #php2shell. In the 10 hours before it was publicly announced, across the @Cloudflare network we saw thousands of attempts to exploit it. That jumped to tens of thousands in the 45 minutes post announcement, hundreds of thousands within 2 hours, and millions now.
UPDATE: Specific mitigation guidance for the recently identified PHP critical vulnerabilities is now available. Secure your servers today. Guidance and technical steps here: nsa.gov/Press-Room/Press-Rel…
Effective Immediately, all organizations using PHP for their systems are advised to be prepared for an update addressing two critical vulnerabilities. PHP is widely used for web applications. These vulnerabilities often provide a direct path to the server's file system or database. If an immediate update is not feasible, it is recommend that organizations take the system offline until it can be fully mitigated. NSA will follow up shortly with more specific guidance.

🚨 BREAKING: Node.js just dropped its OWN security bombshell.
4 HIGH-SEVERITY vulnerabilities patched TODAY, including one that could let hackers remotely execute malicious code on vulnerable servers.
→ 10 SECURITY FLAWS were addressed in today's Node.js release, FOUR rated HIGH severity.
→ REMOTE CODE EXECUTION: CVE-2026-111497 is a serious flaw in Node.js's Brotli decoder that could allow attackers to execute malicious code remotely.
→ TLS SECURITY BYPASS: Two separate vulnerabilities could trick affected applications into accepting certificates for the WRONG server under certain conditions.
→ Think about that. Your application could establish an encrypted connection while failing to properly verify WHO it's talking to.
→ THREE MAJOR NODE.JS VERSIONS AFFECTED: Node.js 22, 24 and 26 all required emergency security updates.
→ RUNNING NODE.JS 18 OR 20? Those versions are END-OF-LIFE and aren't receiving these official security patches.
→ PATCH IMMEDIATELY: Update to Node.js 22.23.4, 24.22.1 or 26.12.1, depending on your release line. If you're using Docker, rebuild and redeploy your containers.
PHP AND Node.js both facing major security disclosures on the SAME DAY.
If you run a website or application, TODAY is the day to check your servers.
And remember: the public release of security patches can give attackers a roadmap to systems that haven't updated.
Don't be the last one to patch.
🚨 A MASSIVE internet security emergency is unfolding right now. 🚨
Two CRITICAL vulnerabilities have been discovered in PHP, potentially putting millions of websites at risk.
→ NEARLY 70% of websites with a known server-side language run PHP. The potential scale is ENORMOUS.
→ TWO CRITICAL security flaws have been confirmed, each scoring 9.2/10 in severity.
→ Attackers could potentially take control of vulnerable servers remotely, without authentication.
→ Reports suggest PHP versions dating back to 2004 could be affected. The exact scope is still unconfirmed.
→ EMERGENCY PATCHES are scheduled for TOMORROW at 10 AM ET. Website owners are being urged to prepare immediately.
→ Europe's CERT-EU is warning organizations to patch ASAP or consider TAKING EXPOSED APPLICATIONS OFFLINE if they cannot be secured.
→ WordPress, Magento, Laravel and potentially millions of other PHP-powered websites could be at risk.
→ Once patches go public, hackers could reverse-engineer them and race to attack servers that haven't updated.
The vulnerabilities are CONFIRMED. The full technical details remain secret.
Tomorrow, the race between hackers and defenders begins.
This could get ugly. FAST.

interpretability might be the most important scientific problem in the world right now, as I don't think we can solve alignment if we don't know what we're building. I think I have good news about it. I co-authored early work in mechanistic interpretability at OpenAI and came away pessimistic, because neural networks appeared to fold into arbitrary tangled knots. years later, I started openai's first large-scale automated interpretability project, finding about 2% of neurons legible with the primitive tools we had
with modern agentic tools and a much closer look, the picture looks totally different. the vast majority in models up to trillions of parameters are legible, and their circuits beautiful. many famous examples of tangled neurons turned out to be misunderstood. The roadblocks I expected mostly aren't there. I now think ambitious interpretability will be solved by the time we need it most, and possibly quite soon, as automated scientists keep improving. it may be a bitter lesson for interpretability: the simple thing, at absurd scale, works
