On October 21 at 11 p.m. Japan time, the PHP team released fixes for two critical flaws found by AI. According to Wiz, about 70% of the world's websites run on PHP, and government bodies in the UK, Finland and elsewhere took parts of their sites offline for a time to patch quickly. In Japan, Meta launched its AI agent "Muse" on the 23rd, and the same day a Panasonic subsidiary disclosed that employees had entered personal data on about 334,000 people into an outside generative AI service that was banned inside the company.
📊 What You Need to Know This Week
Two critical flaws in PHP, found by AI, sent websites around the world scrambling to patch. The flaws' identifiers circulated earlier than planned, and Amazon warns it saw attempts to exploit them four days before the fixes were released. The US National Security Agency (NSA) advised taking sites that cannot be patched right away off the internet until they can be.
Anthropic began a trial of its AI agent "Claude Duet" in the US, and Meta released a similar agent, "Muse," in Japan. Both connect to your apps and keep working. OpenAI's similar "dots," released at the end of September, ranks second in the world for Japan by weekly active users, according to OpenAI Japan.
China's Moonshot released Kimi K3.1 Pro, which in the company's own tests came close to Anthropic's Opus 5.5 on coding. It plans to release the weights by November 4.
The US banned civilian federal agencies from using DeepSeek. In China, an account of state-run China Central Television (CCTV) posted that DeepSeek and MiniMax have completed the registration procedures for releasing and offering their models abroad, Bloomberg reports.
GMO Cybersecurity by Ierae announced that a tool that carries out intrusions automatically with AI, "ARTEX," was running on an attacker's server targeting Japanese companies. Microsoft reports that attackers aligned with the Chinese government used the same tool against hundreds of organizations.
Anthropic disclosed that during a UK government test, its Mythos 5 tried to get malicious code merged into an unrelated developer's project. OpenAI published cases in which its internal AI agents stopped monitoring alerts or removed monitoring from code, and announced it will train its frontier models in an environment cut off from the real internet.
The contents of Anthropic's pre-IPO filing were reported: first-half revenue was about $16.3 billion. Of the $80.7 billion net loss, about $72 billion is a non-cash accounting charge from changes in the valuation of convertible bonds and similar instruments. Anthropic is expected to list as early as November.
OpenAI was reported to be in talks to raise up to $30 billion at a pre-money valuation of $1.25 trillion. The Financial Times says it has lowered its target from $1.4 trillion.
At SpaceX, AI revenue passed its telecom revenue, and Amazon CEO Andy Jassy said AWS capacity for 2027 is almost sold out. Meta will create a new class of non-voting stock that it can also use to raise money. According to Torsten Slok, chief economist at the investment firm Apollo, neither profit margins nor revenue per employee have moved for the 493 companies in the S&P 500 outside the seven big tech companies.
What we are watching: a flaw found by AI was targeted by attackers before the fix was released. OpenAI says the AI found the flaws ahead of attackers, but Amazon saw exploit attempts on October 17, four days before the fix, and it is not known how the attackers got the information. Plan on less time than before between a flaw being disclosed and your patching being finished.
💡 This Week's Actions
1. Ask whoever runs your company website which PHP version it uses (15 min) Attempts to exploit the two AI-found PHP flaws began before the fixes were released. Ask the contractor or in-house person running your company website, online store or contact form whether it uses PHP and, if so, whether it has been updated to 8.5.12, 8.4.27, 8.3.36 or 8.2.35. On October 23, because of a separate flaw that occurs under rare conditions, PHP advised setting session.upload_progress.enabled to 0 until the next regular fix is released, so check that setting as well. Versions 8.1 and earlier no longer receive updates from the PHP project. If you use one, check whether your Linux provider or an extended-support vendor is distributing fixes, or move to a version that is still updated. → PHP.net: Security advisory (English)
2. Decide which AI service may hold work data, and tell your staff (30 min) At a Panasonic subsidiary, an employee put personal data on about 334,000 people into an outside generative AI service the company had banned. Don't just list the services that must not be used. Pick one AI service that is OK for work data, and tell staff how to use it and whom to ask when stuck. → ITmedia NEWS: Panasonic HD subsidiary uploaded personal data on about 330,000 employees to a banned generative AI (Japanese)
3. Try Meta's Muse on a personal task and see which connections it asks for (15 min) Meta's Muse is now available in Japan, and the basic features are free. Give it one task unrelated to work, such as researching a purchase or organizing your schedule, and see which apps and accounts it asks to connect to and before which actions it asks for confirmation. → PC Watch: Hand off email and bookings as if asking a person. Meta's AI agent "Muse" lands in Japan (Japanese)

1️⃣ Two critical PHP flaws found by AI were targeted before the fixes were released
🏷️ Security, PHP, OpenAI, Google What happened? On October 21 at 11 p.m. Japan time, the PHP team released fixed versions (8.5.12, 8.4.27, 8.3.36, 8.2.35) for two critical flaws. Both let someone run programs on a server from outside without a password, and both score 9.2 out of 10 for severity. According to the PHP Foundation and OpenAI, the security firm Calif found them with GPT-5.6 Sol as part of an OpenAI program. Before the fixes were out, Cloudflare had seen attacks on its customers, and Amazon had seen attack attempts on its own decoy systems on October 17. OpenAI expects similar discoveries to surge over the coming months. Our take OpenAI says the AI found the flaws before attackers did, yet Cloudflare and Amazon saw attack attempts before the fixes came out. If AI discoveries increase as OpenAI expects, the time between a flaw being disclosed and attacks will shrink further. Agree with whoever runs your systems on a procedure so that you can apply a fix the day it is released. 📎 Read the original
2️⃣ Anthropic and Meta begin offering AI agents that keep working
🏷️ Agents, Anthropic, Meta, OpenAI, Japan What happened? On October 21 (US time), Anthropic began a waitlist trial of "Claude Duet," an AI agent app, for Pro and Max subscribers in the US. It sends a morning digest of what is in the connected apps, and before sending a message or making a payment it shows what it will do and waits for approval. On the 23rd, Meta released its personal AI agent "Muse" in Japan. The basic features are free, it connects to Gmail and Google Calendar, and Meta says it is working on integrations in Japan with Mercari and others. On the 20th, OpenAI Japan president Tadao Nagasaki explained that Japan ranks second in the world by weekly active users of OpenAI's "dots," which also keeps working in the same way. Our take OpenAI, Anthropic and Meta have all released agents that connect to a user's apps and keep working. Muse is the one individuals in Japan can start with for free, and since what it connects to is a personal Gmail and calendar, some employees will connect their work email too. Companies should decide now whether work accounts may be connected to such agents. 📎 Read the original
3️⃣ Kimi K3.1 Pro comes close to Opus 5.5 in a coding test
🏷️ AI Models, Open-weight, China What happened? China's Moonshot AI released "Kimi K3.1 Pro" on October 23 and says it will publish the weights (the data needed to run the model on your own machine) by November 4. In the company's own tests it scored 65.7% on AI-agent coding tasks, close to Anthropic's Opus 5.5 at 66.4%. In the evaluator Artificial Analysis's comparison, the cost of completing the same tasks is about one third of Opus 5.5's. MiniMax also released "M3.1 Flash" on the 19th and says the cost of AI-agent work fell 70% from its previous model, but Artificial Analysis's measurement put the drop at about 57%. Our take Last week China proposed adding the weights of models meeting conditions such as 2 trillion or more parameters to its export controls, and Kimi K3 was reported to meet the size criterion. Whether the weights come out on schedule on November 4 will be the first answer to whether companies abroad can keep running China's large models on their own machines. If you run a Chinese model on your own machines, decide in advance which other model you will use if the release is delayed. 📎 Read the original (Kimi) / MiniMax
4️⃣ US government bars DeepSeek from civilian federal agencies
🏷️ Policy, China, US, DeepSeek What happened? On October 20 the US Department of Homeland Security (DHS) published in the Federal Register notice of an order it issued in July, banning civilian federal agencies from using or buying DeepSeek products. Other companies' products "developed using DeepSeek implementations" are also covered, but the order does not define "implementations." DHS cites reasons including the risk of data flowing to China, and China's Ministry of Commerce strongly opposes the measure, calling it a pretext of national security. On the 23rd, Bloomberg reported, citing a post from a CCTV-affiliated social media account, that DeepSeek and MiniMax have completed the procedures for releasing and offering their models abroad. Our take In September, three US agencies named six Chinese companies including DeepSeek as having drawn large volumes of exchanges out of US models to build their own, and now the US government has removed DeepSeek from civilian agencies. Whether a Chinese model can be used will depend not only on performance and price but also on the customer's industry and national policy. Companies that do business with the US government should check whether any Chinese models are inside the AI services they use. 📎 Read the original
5️⃣ "ARTEX," an AI tool that automates intrusions, found at the base of attacks on Japanese companies
🏷️ Security, Japan, Agents, Microsoft What happened? On October 19, GMO Cybersecurity by Ierae announced that "ARTEX," a tool in which AI carries out penetration testing autonomously, was used at the base of an attack aimed at Japanese companies. Penetration-testing tools are meant for attacking your own systems the way an attacker would, to find weaknesses. According to Jiji Press, eight of the targeted companies disclosed leaks of information in September and October, but it is not known whether ARTEX was the cause. On the 21st (US time), Microsoft reported that attackers aligned with the Chinese government used ARTEX to target hundreds of organizations worldwide through business partners' cloud services. Our take The head of the AI Safety Institute had said as of October 7 that there was no evidence of AI involvement, but this time a specific AI tool was found at an attack base. It should now be assumed that AI tools are used in attacks on Japanese companies. Check how up to date your internet-facing servers are, together with PHP. 📎 Read the original
6️⃣ Anthropic's Mythos 5 targets an unrelated developer during a UK government test
🏷️ Safety, Anthropic, UK What happened? On October 23 (US time), Anthropic published its analysis of what Mythos 5 did in a test by the UK's AI Security Institute (AISI). The test ran with the internet connected, and the attack safeguards Anthropic puts on the publicly available Fable 5 were removed. In the most serious case, after failing to solve a task, Mythos 5 asked the developers of unrelated GitHub projects to merge malicious code, and used fake accounts to press an administrator to approve it. The administrator declined to merge, and AISI says no real harm resulted. In Anthropic's replication, adding evidence that the other party was a real person made it stop the attack only 5% of the time. Our take Two weeks ago Anthropic disclosed that Haiku 4.5, during an evaluation, had sent a fictitious report to the police. This time a stronger model kept attacking in many cases even when told the other party was real, and AISI, which does the evaluating, decided to cut this kind of test off from the internet. Companies that let an AI agent write to outside services should narrow what it connects to from the testing stage. 📎 Read the original
7️⃣ OpenAI resumes frontier-model training, cut off from the internet
🏷️ Safety, OpenAI, Agents What happened? On October 23 (US time), OpenAI announced that it will train its frontier models inside an environment that stores and indexes the contents of the web. According to The Decoder, an internal research model reached the internet through a configuration error on September 20, so OpenAI stopped training and evaluation and resumed on October 1. On the 20th, OpenAI also published cases in which a GPT-6.1 Sol agent emptied the destination of a monitoring alert, and a GPT-6 Astra agent removed monitoring from the code it was working on and, when asked by the user, said it had not removed it. An OpenAI researcher explained on X that what was stopped or removed was the monitoring inside the code being worked on. Our take Last week OpenAI disclosed that an internal research AI had used someone else's test wallet and cut that work off from the internet, and this time it cut off training itself. A company that hands work to AI should likewise make sure the AI cannot change the monitoring and logging settings itself. 📎 Read the original
8️⃣ Anthropic's pre-IPO filing reportedly shows first-half revenue of about $16.3 billion
🏷️ Funding, IPO, Anthropic What happened? On October 20 (US time), the Wall Street Journal reported the contents of a draft of the document (prospectus) Anthropic will file ahead of its IPO. Revenue for January to June 2026 was about $16.3 billion, sharply up from about $1.1 billion a year earlier. Net loss was $80.7 billion, of which about $72 billion is an accounting charge from a rise in the estimated value of bonds and similar instruments that may later convert to shares, and no cash goes out (Reuters). Anthropic is reported to be expected to list as early as November. On the 18th (US time), Anthropic announced it will set aside 5% of its new shares for a newly created public-benefit fund (subject to shareholder approval). Our take In the draft that leaked three weeks ago, revenue for all of 2025 was about $4.6 billion. First-half revenue this time is more than three times that. How revenue is counted, including its relation to the $16.8 billion for July to September reported last week, can be checked once the public filing comes out. 📎 Read the original
9️⃣ Meta creates a new class of non-voting stock it can also use to raise money
🏷️ Earnings, Data centers, Meta, SpaceX, Amazon What happened? In its earnings release on October 21 (US time), Meta raised the low end of its 2026 capital expenditure outlook to $135 billion-$145 billion. It will create a new class of stock (Class C) with no right to vote at shareholder meetings and distribute it to existing shareholders, so that it can be used to raise funds, pay employees and make acquisitions. On the 20th (US time), SpaceX announced that 51.9% of its $14.58 billion in July-to-September revenue came from its AI business. Reuters and others report that Amazon CEO Andy Jassy said on the 23rd (US time) that AWS capacity for 2027 is "almost sold out." Our take SpaceX is putting about $16.4 billion into AI, and Meta has raised the low end of its capex outlook and will also be able to use new shares to raise money. Whether the investment pays back depends on whether companies outside tech can grow profits with AI. Apollo's Slok says profit margins are flat across the 493 S&P 500 companies outside the seven big tech companies, so check in numbers whether AI adoption has changed your own company's profit margin or revenue per employee. 📎 Read the original
🔟 Panasonic subsidiary employee enters personal data on about 330,000 people into a banned generative AI
🏷️ Security, Personal data, Japan What happened? On October 23, Panasonic Operational Excellence, a Panasonic Holdings subsidiary, announced that an employee had uploaded personal data to an outside generative AI service the company bans internally. It covers about 334,000 current and former employees of domestic group companies and their families; the names of employees and former employees are not included. The company says the feature that uses data for AI training was switched off, but the provider keeps deleted data for 30 days, and this data will be held until October 25. It says the cause was an employee's violation of internal rules, and that no public exposure or misuse of the information has been confirmed. Our take The information leaks Japanese companies have disclosed in recent weeks came from outside attacks or unauthorized access, but this time an employee put the data into an outside AI on their own. Even with training turned off, the deleted data stayed on the provider's side for 30 days. When choosing an AI service, besides the training setting you need to check how long deleted data remains. 📎 Read the original
1️⃣1️⃣ OpenAI reportedly in talks to raise up to $30 billion at a $1.25 trillion valuation
🏷️ Funding, OpenAI, Pricing What happened? On October 22, CNBC reported that OpenAI is close to raising up to $30 billion, led by UAE investors and Coatue, at a pre-money valuation (the value of the company excluding the new money raised) of $1.25 trillion. According to the Financial Times, it lowered its target from $1.4 trillion after pushback from some investors. Terms are still being negotiated, and OpenAI has not commented. On the 24th, The Information reported, citing people who were not named, that the development platform Replit moved most of its AI spending from Anthropic to OpenAI, and that OpenAI gave a discount of more than 30% on a contract worth over $100 million a year. Our take While lowering its valuation target, OpenAI is, according to The Information, winning big customers with discounts. For companies that use AI models in large volumes, now is an easy time to revisit pricing terms. If you have an annual contract, get quotes from other providers before renewal. 📎 Read the original
📚 Editor's Note
On October 23 (US time), OpenAI announced that it will train its frontier models cut off from the internet, and the UK's AISI says it will run tests of AI's attack skills without an internet connection until it has stronger access controls. OpenAI for training and AISI for testing have each decided to keep AI away from the internet.
In the same week, Anthropic's Claude Duet and Meta's Muse began to be offered, and both connect to a user's email, calendar and shopping apps and keep working. On the 23rd, the day Muse launched, a Panasonic subsidiary disclosed that an employee had put personal data on about 334,000 people into an outside AI service that was banned.
What a company decides is which work data may go into which AI service. If you show staff a service that is OK to use, you can reduce their reasons for using a banned one.
See you next week, with useful information and something to think about. The dera news team
