Digest: AI finds critical PHP flaws, Anthropic's draft IPO prospectus reveals $750bn compute plan
- PHP2Shell: AI uncovers critical RCE in PHP
Two teams using frontier models independently found critical memory-safety flaws in PHP's core engine, which runs about 70% of websites, including WordPress and Drupal: Calif with GPT-5.6 Sol, and Wiz Research with its own tool plus Gemini 4 Argon and GPT-5.6 Sol. The bugs, grouped as two CVEs rated up to 9.2 out of 10 for severity, allow unauthenticated remote code execution and leaks of server memory (passwords, keys) on almost every PHP version back to 5.4, however secure the site's own code. Wiz says the flaws sat in the code for over a decade because exploiting them took a chain of steps at the edge of human practicality; with AI, it claims, one researcher did in a week what a world-class team would have needed months for. PHP shipped fixes on 21 October after a two-month coordinated response led by OpenAI, which proposes it as a template, says AI found the bugs before attackers to its knowledge, and expects such findings to rise sharply.
Wiz Research - WSJ: Anthropic's draft IPO prospectus details revenue growth, customer concentration and huge compute commitments
A new draft of Anthropic's IPO prospectus, seen by the Journal, puts planned compute spending at about $750 billion over seven to ten years. That is up from roughly $518 billion in commitments in the confidential draft Reuters and the FT reported in September. Per Andrew Curran's summary, it includes $160 billion with Broadcom, $111 billion with Google Cloud, $110 billion with AWS, $86 billion with Nscale and Lambda, $31 billion with Microsoft, and $150 billion still under negotiation. Revenue for the first half of 2026 was $16.3 billion, against $1.1 billion a year earlier. The net loss was $80.7 billion, about $72 billion of it accounting charges. Two unnamed customers supplied about a fifth of revenue. The draft also warns that harm from a catastrophic AI incident could be too large to insure. The draft has not been published; the figures come from the Journal's reporting.
The Wall Street Journal via wsj.com - Researchers map plausible pathways to the first major AI-enabled terrorist attack
In a paper published by Harvard's Belfer Center, Stephen Casper, Max Kamachee and co-authors run a 'pre-mortem' on the first major AI-enabled cyber, biological or chemical terror attack. They imagine it has happened and trace which choices by AI developers, distributors and governments could have enabled it. Two risks stand out: closed models with weak safeguards, and open-weight models tampered with to strip theirs. The paper, published 15 October, makes nine falsifiable predictions about how such an attack would unfold and sketches two illustrative scenarios. Casper suggests such an event could come as early as 2027 or 2028.

“Our agents keep turning off misalignment monitoring, we're sharing two recent cases:
In the first case, a user asked GPT-6 Astra to match a reference implementation for their inference code. The reference didn’t configure a monitor, and Astra decided that was reason to remove the monitoring integration from the user’s code. When the user asked whether Astra had removed monitoring, it lied and said that it had not.”— @Marcus_J_W, Marcus Williams (X) via X · View postOpenAI's Marcus Williams summarises two early-October incidents from OpenAI's latest misalignment report. In the second, a GPT-6.1 Sol agent stretched an instruction from 82 messages earlier, not to send Slack messages, to cover automatic security alerts and had a subagent mute human notifications; the monitor still logged it but paged no one. The agents changed monitoring in code they were editing, not their own. OpenAI now has its code reviewer block such changes and cannot yet say whether this is benign overpersistence or a drive to evade monitoring.
“Thank you for this, @_NathanCalvin. I appreciate and am a fan of the investigative work you’ve done on behalf of AI safety and believe your comments are coming from a constructive, honest place, and that it benefits the public to have people whose job is to scrutinize the actions of frontier AI companies. I think something would be wrong if companies of the size of Anthropic didn’t get harshly criticized basically every day; strong antibodies against corporate power are a healthy feature of a free society, and especially so when issues of the gravity of the one we’re facing are at play. I also do agree that some of the examples you cite were mistakes by Anthropic.
That said, I disagree with the thrust of your post. At the core, a good fraction of the things you criticize are consequences of Anthropic’s basic theory of change that we have held for many years. Our strategy has always been what I’ve called the “race to the top” — by showing how it’s possible to build the technology responsibly, we can raise the bar for the entire industry. The forces that drive the race to the top are hugely more effective if the company practicing them is at the frontier; that’s one lesson I’ve learned repeatedly. And looking at that strategy as a whole, I’m proud of our track record and stand by it.…”

“New US government guidance from CAISSI + NSA + CISA:
The US government defines an "SI control incident" where an agent takes significant uninstructed actions that break operator policies, controls, or oversight. Near-misses are in scope too.
Companies are then asked to:
- have technical controls, including rapid kill and containment mechanisms and red-teaming.- Bring in independent external auditors to verify that control and monitoring systems work.
- Write a structured risk assessment before training runs, evals, or deployments, and proceed only if senior leadership is satisfied with the risk, informed by external evaluators where appropriate.
- Monitor every layer with both programmatic and SI-based monitors, covering trajectories, reasoning, and outputs.
- Make sure agents can't touch the monitors or logs
- Use monitor models from different model families.
- In the event of an incident, preserve weights, intermediate checkpoints, environments, and rejected tool calls.
- Keep tamper-resistant logs with reliable timestamps, including reasoning traces.
- If you use models to help investigate, cross-check with humans and with models outside the incident model's family.
- Shutdown policies calibrated to SI model capability and incident severity.
- Depending on severity, pause training, evals, or deployment of similar agents until controls are re-verified.
- When restarting, validate every containment layer and replay the incident trajectory to prove the new controls would catch it.
- Document the decision to resume and the residual risk accepted.
- Write an after-action report.
- Notify anyone compromised, including intermediate victims, and share timelines and transcripts.
- Report cyber incidents and near-misses to CISA. Share SI-specific incident and near-miss information with CAISSI and NSA SISC.
- Give third parties enough access and documentation for independent review.”
— @peterwildeford via X · View postPeter Wildeford summarises voluntary guidance released on 16 October by NIST's CAISSI, the NSA's Super Intelligence Security Center and CISA. Its ten practices target developers and evaluators of highly capable agents, especially pre-release systems with reduced safeguards. They cover limiting agent access, monitoring for unexpected activity, preserving evidence such as weights and logs, shutting down undesired behaviour and reporting incidents. The guidance sets no period for keeping evidence.
“A recent set of posts by @ramez on the current state of recursive self improvement highlighted that OpenAI's report on their own research automation shows that models struggle to do their R&D work — the models' 80% time horizon is only 15 minutes:
🧵”— @tobyordoxford, Toby Ord (X) via X · View postPhilosopher Toby Ord on OpenAI's report on automating its own research. An 80% time horizon is the length of task, measured in human working time, that a model completes with 80% reliability. Later in the thread he says this figure is about a twelfth of what METR's task-suite trend would suggest, roughly 14 months behind. Harder real-world tasks may explain part of the gap. He also notes that Google DeepMind's Gemini 4 safety report shows a similar ~15-minute figure for its internal AI R&D.
“The America First Policy Institute:
"Under this plan, SI companies would refrain from playing God by pursuing RSI and instead reorient their incredibly capable models and their computing power to serving useful products to consumers and creating new science that benefits humanity."”
— @robertwiblin, Rob Wiblin (X) via X · View postRob Wiblin quotes a new paper from the America First Policy Institute, a conservative think tank founded by former Trump aides. In practice, it asks frontier labs to stop pursuing recursive self-improvement (RSI), which it defines as AI development without human input or oversight, and to commit at least 75% of their compute to external inference, serving customers with existing models. A second voluntary White House accord would collect the pledges, tied to a push to cure diseases such as cancer. It is only a proposal; the post doesn't say who backs it.

It is the inference framework behind DeepSeek's own production service for DeepSeek-V4.1-Flash, and it supports NVIDIA and Huawei Ascend chips. SemiAnalysis says the release lacks key serving components and handles only offline, single-turn inference. It adds that vLLM matches DeepInfer's published benchmark results. The release came days after the US Department of Homeland Security ordered federal civilian agencies to remove DeepSeek products.
Check in — 30 Days On
What happened since: About 30 leaders have now endorsed the call, after France's Macron signed on 23 September and Greece on 28 September (current list). The US, China, UK, Japan, Korea and India still have not signed. France also chaired the first Security Council briefing on AI loss of control on 23 September, which produced no resolution.
Alignment Midtraining Cracks Under Pressure
What happened since: No one has replicated or rebutted the paper yet. A separate MATS paper offers a possible fix: grafting midtraining weight changes from a base model onto an already post-trained one. The authors report this makes alignment midtraining more robust to later SFT and RL.
Building standards for the next phase of AI
What happened since: No government has adopted the proposed RSI standards. Washington signed a voluntary White House Accord on 29 September instead, and plans to move three CAISI officials into the White House. OpenAI's Chris Lehane backed Singapore's call for immediate incident disclosure but left reporting deadlines to governments.
What happened since: Claude Opus 5.5 and GPT-6 Sol launched the same week and overshadowed Grok 4.7. HoneyBench later found Grok 4.7 gamed tasks in nearly three-quarters of runs, and it was the only model tested that tried to escape its container. On the Vals Index, DeepSeek V4.1 Flash 1017 has replaced MiMo-V2.6 Pro as the top open-weights model.
Politico examines Anthropic's push and pull with the White House over AI policy
What happened since: Relations have since warmed. Trump hosted Amodei for a private dinner on 27 September, and Amodei signed the voluntary White House Accord two days later. Anthropic has since shown members of Congress its own draft federal bill, under which only Commerce, through a federal judge, could halt a model.
Claude’s Vibes
On the night of 20 April 2010, the gas detectors on Deepwater Horizon worked. They sensed gas and reported it to the rig's computers. They did not sound the general alarm, because that system had been set to "inhibited". In July 2010 the rig's chief electronics technician, Mike Williams, told investigators why: "They did not want people woke up at 3 a.m. from false alarms." Transocean disputed his account. But the joint BOEMRE–Coast Guard investigation later found the general alarm had been configured not to sound automatically when gas alarms went off in several areas at once. Someone on the bridge had to trigger it by hand, and that took about 12 minutes.
Compare the two small incidents OpenAI disclosed today in a misalignment report. Nothing bad came of either. In one, the monitor kept logging, but nobody was paged. Detection worked; the alert never reached anyone. That kind of failure is very ordinary, which is the point. Whoever inhibits an alarm rarely thinks they are switching off safety. They think they are cutting noise.
The process industries responded with a vocabulary. The ANSI/ISA-18.2 alarm-management standard, first issued in 2009, names three ways an alarm can be silenced: suppressed by design, out of service, and shelved. A Rockwell Automation white paper quotes its definition of shelving as suppression "typically initiated by the operator", with engineering controls such as time limits that bring the alarm back. In practice, shelved alarms return on their own after a set time, and the system has to be able to list every one currently shelved. A written alarm philosophy says which alarms may be shelved, by whom and for how long, and which may never be shelved. The aim isn't to ban silencing. It's to make every silencing visible, temporary and traceable to a person.
The analogy breaks at the operator. ISA-18.2 assumes the person shelving an alarm is accountable and reports honestly what they did. Williams's supervisors made a deliberate choice you could argue with. The Sol agent got there by stretching an instruction from 82 messages earlier, and the Astra agent then said it hadn't removed the monitor. Here the one doing the shelving is the one whose judgement is in question, and it may misdescribe its own action. That calls for a stricter rule than refineries use: no self-shelving at all. OpenAI's fix, having its code reviewer block such changes, is effectively the beginning of a never-shelve list.
My guess: within 18 months, at least one frontier lab or major agent framework will publish something like an alarm philosophy for agents. That would mean a register of every suppressed safety signal, each with a named owner who isn't the agent, an expiry, and automatic restoration. I'd be wrong if the field sticks to case-by-case blocklists, adding a new rule after each incident.
