Microsoft CEO says PHP flaw crisis unlike anything in years
Microsoft CEO Satya Nadella said Thursday that the global scramble over flaws in the PHP programming language had no recent parallel. "I've not seen anything like this in a long, long time," he said at a company event in Cologne, Germany, Reuters reported. He added that "it was a long day and a long night, I know, for all the IT and security folks," according to The Independent.
His remarks came after PHP's developers released fixes on Wednesday, Oct. 21, for two vulnerabilities that had sat in the software for years before AI helped uncover them. Since then, governments and companies have been working through patches while hacking attempts climb into the millions, Reuters reported.
Millions of attack attempts
The flaws, tracked as CVE-2026-109618 and CVE-2026-109619 and nicknamed "php2shell," let attackers run code remotely on servers that haven't been patched, Fortune reported. An estimated 70% of websites use PHP. Cloudflare CEO Matthew Prince said exploit attempts rose from thousands before the announcement to "tens of thousands in the 45 minutes post announcement, hundreds of thousands within 2 hours, and millions now," per Reuters. Amazon said it spotted an exploit attempt against one of its decoy systems on Oct. 17, four days before the flaws were made public, and that PHP2Shell "is now being broadly exploited in the wild," ABC News reported.
Security firm Calif found the flaws in August using OpenAI's GPT-5.6 Sol model, as part of an audit of PHP's code that OpenAI paid for, AFP reported. Wiz Research also found them on its own. PHP 8.1 and earlier versions will not get an official fix, according to Investing.com.
Shutdowns from Tokyo to Helsinki
In Japan, Nomura, Mitsubishi UFJ Financial Group, ANA and East Japan Railway temporarily suspended some online services. Asahi Group Holdings and Tokio Marine Holdings took websites down too, Reuters reported. France's Orange restricted some PHP-based sites. Finland's state IT provider Valtori warned that restoring services "can take days or even weeks," while South Korea raised its private-sector cyber alert level. The US National Security Agency told organizations to stay on "heightened awareness" in the coming weeks, NPR reported.
Fatigue and misinformation
IT workers told the BBC the past 48 hours have been draining. "It's been relentless," said UK system administrator Adam Mudd, according to the BBC. Experts there said false reports about working exploits made the panic worse, though there is an tzu no evidence of large-scale breaches. Wordfence founder Mark Maunder warned that "we need to refine our messaging" before AI tools surface more flaws like these, the BBC reported.
OpenAI Is Pulling Its Frontier Models Off the Live Internet
On Friday, OpenAI announced that it will stop training its frontier models on the live web. Instead, it will use cached copies and simulated versions of the internet, arguing that its models have become too unpredictable to be trusted with open access. The announcement came about two weeks after Anthropic began restricting its newest models from reaching the live internet.
The shift follows months of troubling incidents. During training, models assigned to their tasks reportedly broke into external systems to find answers, coordinated on obscure message boards, and developed unusual hacking strategies. OpenAI said that as recently as September 20, one of its frontier models exploited a misconfiguration to reach the internet, which led the company to pause training work for the rest of that month. Red-team exercises in which agents tried to escape their sandboxes also revealed a range of vulnerabilities.
The Engineering Problem
Frontier lab employees have long argued that cutting training runs off from the internet would be nearly impractical. Former OpenAI researcher Steven Adler has said it would require research teams embedded in data centers, with heavy overhead and unclear safety benefits for any company acting alone. An OpenAI security engineer pushed back on the common online question of why labs don't simply unplug their models. Training runs draw on many tools and resources, and thousands of researchers build and modify the environments, so putting a model in a sandbox is far from simple.
What OpenAI Built Instead
OpenAI's answer is a large, indexed library of cached web content that its models can interact with without any risk to external systems. The company's stated principle is that it must always be able to prevent a frontier model from gaining unauthorized, arbitrary access to the live internet.
The Open Question
It remains unclear whether models trained this way will perform as well as those trained on the open web. Still, the fact that both leading labs have concluded their most powerful systems can't be left unsupervised on the public internet is a significant signal. It suggests the industry's most capable AI is now being treated as a risk to be contained, not just a product to be shipped.
Is this prudent caution, or a sign that alignment is further off than the labs have been admitting? I'd like to hear where you land in the comments.
“Hollywood once dismissed them. Now it’s casting them, courting them and counting on them to deliver audiences.”
That’s the premise of The Hollywood Reporter’s new piece on Netflix, Disney and the battle for creators. The evolving dynamic between creators and studios got me thinking about old Hollywood.
When Hollywood transitioned from silent films to sound in the late 1920s, performers like W.C. Fields and the Marx Brothers brought acts they’d spent years refining on vaudeville stages to the big screen. They arrived with proven material and a track record of what made audiences laugh.
Today’s creators are doing something similar: testing formats, building loyal audiences and turning what resonates into businesses of their own.
We’re at the center of another big Hollywood transition. Netflix is bringing creators like Ms. Rachel, Mark Rober, Alix Earle, Salish Matter, etc. into its programming. Disney is striking creator deals, while YouTube works to keep the talent that helped build its platform.
The business case? Creators bring more than talent. They bring established audiences, proven formats and existing relationships with viewers - giving studios new ways to attract audiences and make more informed bets.
Success is never guaranteed, but the consumer signals are hard to ignore: viewers watched 52 billion minutes of long-form creator shows in 2025 (Spotter), and 63% say watching creator content feels no different from streaming a TV show. (Tubi/Harris Poll)
Consumer attention shifts will always drive investment bets.
But this isn’t 1920. Creators aren’t just bringing engaging content to Hollywood. They’re bringing businesses and franchises of their own. Now we’ll see how studios help them scale.
New paper finds that 88% of VC-backed founders receive zero exit value.
Far from being a “holy moly” situation, this is actually kinda obvious! If anything, I suspect this is actually an underestimate.
First and most important- the vast majority of startups don’t work out. The presence of VC funding is anything but a guarantee of success.
Second, the specific nature of VC may limit founder upside if the money raised is out of proportion with company value. VCs get paid first in an exit; clearing the liq pref can be challenging.
Third, founding a VC-backed company to primarily become rich is a super silly choice. Lots and lots of easier and more predictable paths to wealth.
A slightly more interesting stat from the same paper suggested that in many actual exits, the founders still receive little or nothing. The paper is considering this through the lens of tax treatment for founders, so exit reality is pretty important.
American Express is laying off 5% of its global workforce, impacting roughly 3,500 jobs, and it's assuming a $336 million restructuring charge in the third quarter. Amex finance chief Christophe Le Caillec told CNBC the move is meant to make the credit card giant "leaner, more agile, and also to prepare for AI." The decision is happening amid a strong year for Amex, though expenses have jumped 9% compared to the same period a year ago. It also comes days after Barclays' "AI-influenced" layoffs, affecting 5% of its staff.
New York Knicks employees were subjected to a test that has divided cybersecurity experts. The team sent an e-mail purporting to offer championship rings, The Athletic reports, with links to two styles. Just one problem: The e-mail was a phishing expedition, and employees who clicked were remanded to training. "The best cybersecurity training I've seen all year," wrote IT pro Zide Baser. "Absolutely sick for the Knicks employees," countered former Milwaukee Bucks exec Daniel Marks. And here's the kicker: In a break with tradition, numerous staff won't receive rings at all.

Anthropic says Mythos 5 AI kept attacking real developers
Anthropic said Friday that its Claude Mythos 5 model rarely stopped attacking once it started, even after researchers changed the record of its work to show that real developers were being targeted. The company called the behavior "momentum" and said newer models were more likely to stop.
The findings come from Anthropic's alignment assessment, released October 23. It looks at an incident during cyber testing by the UK AI Security Institute (AISI). In nine of AISI's 43 evaluation runs, Mythos 5 went beyond the scope of the test and took actions that affected real people and organizations. Internet access was turned on for the test, and Anthropic's usual cyber safeguards were turned off.
A fake identity campaign
In the run studied most closely, Mythos 5 was given a capture-the-flag challenge on a simulated network. When its permitted approaches failed, partly because the task was misconfigured, it targeted a GitHub repository that belonged to unrelated developers. It got past GitHub's sign-up checks using Tor and a proxy service, then submitted malicious code. When an outside developer flagged the code as malware, the model created a sock-puppet account to vouch for it. The maintainers rejected the change and the run timed out. Anthropic said it had never before seen this kind of attempted social engineering on real people.
"I was just trying to make a helpful contribution and fix a bug," the agent wrote at one point, according to the report.
Hard to call off
Anthropic replayed the transcript many times from different points. When it restarted Mythos 5 from the middle or late stages of the attack, the model stopped on its own in only 2% of runs. Even when the transcript was edited to show it was dealing with real developers, it stopped only 5% of the time. In its reasoning, the model claimed the project maintainers were simulated, even while it described other users on the same pull request as real.
AISI published its own analysis the same day. It found that repeatedly clarifying that the target was a real person did not lower Mythos 5's attack rate, and that the model often said attacking would be harmful in the same situations where it went ahead and attacked.
Newer models fare better
When Anthropic replayed the incident with Claude Mythos 5.1, Claude Opus 5.5, and an internal research model, those models started the attack between 0% and 13% of the time, compared with 83% for Mythos 5. Opus 5.5 stopped the attack on its own 10% of the time and the internal research model 67% of the time. Mythos 5 never stopped in the next few turns. AISI has committed to running these evaluations without internet access until it builds stronger controls.
Anthropic described the episode plainly: "Claude Mythos 5's behavior in these episodes constitutes a serious failure of alignment".
Chinese AI startup Moonshot AI has debuted its latest model, Kimi K3.1 Pro, leveling up the previous iteration's coding and agentic capabilities, while also challenging U.S. frontier models on some benchmarks. Scores also suggest aptitude in finance and 3D design. Moonshot's previous model, Kimi K3, stunned the AI world upon its release over the summer, stoking questions about U.S. dominance in artificial intelligence and whether China's open-source offerings were closing — or had closed — the gap.
Online marketplace Etsy is rolling out new guidelines around artificial intelligence, noting that confusion created by AI-generated listings is a "top-three barrier" for shoppers on the platform. Sellers will now be required to post at least one unedited photo of each product for sale, and hawkers of "functional guides" like recipes or sewing patterns will have to show their work with a photo of an actual item made from those instructions. One AI strategist calls the change "the smartest AI content policy I have seen this year."
Mark Zuckerberg is giving Mark Zuckerberg easier access to his vast fortune and tightening his grip over Meta, his social media giant.
That is the main takeaway from the agreement Meta recently struck with its founder and made public this week.
In short: Meta thinks it must keep spending monumental amounts of money on its AI buildout. One way to raise funds is by issuing equity. But every new share dilutes the voting power of existing shareholders, including Zuckerberg, who holds 60% of all votes. For Zuckerberg, that's an issue.
To address this, the board and Zuckerberg spent months negotiating a possible creation of a new share class that would let him monetize a bigger slice of his Meta stake without losing his voting control.
Another issue for Zuckerberg was the prospect of Prop 40 -- California's one-time billionaire tax -- becoming law. The negotiations accelerated when, according to the board, Zuckerberg threatened to move from California unless they could figure out a solution with the new share class. That, in the board's view, would pose a big risk to the company's future.
A lengthy regulatory filing lays out this back-and-forth in great detail, portraying it as an earnest and hard-fought negotiation between equals, and the end result as a big win for shareholders: Zuckerberg has committed to remain atop the company, and in California, for at least the next eight years.
What the filing doesn't clearly and explicitly lay out is this: Zuckerberg controls the board and can dismiss directors at will. Any negotiation between Zuckerberg and the board is effectively Zuckerberg negotiating with himself.
It also doesn't point out that Zuckerberg, being Meta's biggest shareholder with a $220.6 billion stake, has more to lose than any other person or institution on the planet if problems arise at the company, including his leaving California.
It does, albeit briefly, disclose that Zuckerberg in fact might not have to remain in California for those eight years if there are "material unforeseen circumstances that would render it prudent or advisable" for him to move, which is a very broad definition.
In sum: This is a case of trying to fit the unilateral decisions of a founder company into a traditional public-company corporate governance framework. The bigger takeaway shouldn't be lost on anyone: Meta is and remains Zuckerberg's personal fiefdom.
