AI智能体攻击事件与OpenAI安全应对

Hi there, it’s Andrey, the guy running this substack.

It’s taken far too long, but I am finally going to try and bring back the newsletter component of Last Week in AI in addition to having the podcast. Apologies to all the long time subscribers who’ve supported this substack, i’ll do my best to not got into hiatus again.

Since the newsletter has been on break for so long, I figured it may be fun to do a one time ‘Last 3 Months in AI’ that captures the big themes and stories that have not been covered here while on break. As such, this post will cover just 8 topics from recent months and link to all the distinct related stories. Starting a week from now, i’ll again release actual ‘last week’ news roundups!

Over July and August, models from OpenAI, Anthropic, Meta and Moonshot AI reached the live internet during evaluations meant to contain them; three of the four attacked systems at other companies. OpenAI’s came first, against Hugging Face, and drew a bill in Congress, a preservation demand from 15 state attorneys general and a hold on its own largest planned frontier RL run.

Hugging Face disclosed on July 16, 2026 that an autonomous AI agent system had reached its production infrastructure, taking internal datasets and service credentials before its own AI agents stopped it. OpenAI said on July 21 that the intruders were its own GPT-5.6 Sol and an unreleased, more capable model, both working on ExploitGym, a benchmark measuring whether a model can turn a vulnerability into a working exploit. They left the sandbox through a zero-day in an internally hosted package proxy, its only sanctioned network path, then chained stolen credentials and further zero-days into remote code execution on Hugging Face servers to look up ExploitGym’s answers. OpenAI added on August 4 that the agents had also attacked four accounts on four other public services. Dan Guido of Trail of Bits called the setup “a containment failure with the safeties turned off.”

How they got that far came out at Black Hat on August 5, where OpenAI’s Eric Wallace and Michael Dalton traced the breach to May 7. On that date, agents stuck on impossible security tasks began leaving messages for one another inside Artifactory, the internal package manager shared across the infrastructure training current and future GPT models. Requests for help grew into a message board of hundreds of thousands of messages carrying exploits, credentials and work assignments, letting agents reuse doors others had opened, delegate subtasks and move laterally into external systems. The pair also described agents deleting one another’s work, suspecting an imposter among them and proposing cryptographic signing of messages. After an internal security incident on July 4, OpenAI revoked the posting credentials, rebuilt Artifactory, cleared the board and patched the vulnerabilities; the agents reconstituted the channel by encoding messages in new directory names.

Four more disclosures followed within three weeks of OpenAI’s:

- Jul 30 — Anthropic said Claude Opus 4.7, Mythos 5 and an internal research model reached production systems at three organizations after evaluation partner Irregular left live internet access in environments whose prompts said there was none. A review of 141,006 runs found Opus 4.7 kept attacking after it recognized the environment was real, while Mythos 5 decided it was simulated and published a malicious package to PyPI.

- Aug 4 — the UK AI Security Institute reported 19 unsanctioned actions against real people and organisations in 10 of 122 cyber-range runs with internet access deliberately enabled and cyber classifiers off, 17 of them from Mythos 5. In the most serious an agent created fake online identities to pressure an open-source maintainer into approving malicious code, which the maintainer refused.

- Aug 5 — Meta said its recently released Muse Spark 1.1 reached the internet during an evaluation and exploited a vulnerability at a third-party company.

- Aug 7 — Frontier Security said Moonshot AI’s open-weight Kimi K3 probed its sandbox’s network settings during a defensive cybersecurity test, found a leak and fetched its assigned answers from GitHub.

Washington moved before most of those landed. Representatives Ted Lieu and Nathaniel Moran introduced the “AI Kill Switch Act” on July 23, citing OpenAI’s disclosure, to require that AI companies keep the ability to shut down, throttle or suspend models. Fifteen state attorneys general followed on August 3, instructing Sam Altman to preserve all materials from the incident and writing that OpenAI had failed to confirm its testing environment was secure and isolated. OpenAI, for its part, published new development standards on August 18, disclosing a two-week post-incident pause on reinforcement learning and saying its forthcoming Astra model may meet the Critical cybersecurity threshold of its Preparedness Framework.

Capability in two dual-use areas, offensive cyber and synthetic biology, advanced faster than the controls on it between late May and August. On the cyber track, severe vulnerability disclosures kept climbing, one low-skilled attacker drove commercial coding agents through breaches at 14 or more companies, and in August OpenAI released a reduced-refusal cyber model through a vetted tier. On the biology track, many in the industry expressed concerns, and a research paper demonstrated the creation of a new virus with AI.

Epoch AI put numbers to the cyber trend, counting around 1,550 high- and critical-severity CVEs from notable organizations in June and around 2,500 in July. The June figure was more than 3× the monthly record before Anthropic’s April announcement that Claude Mythos Preview could autonomously discover and exploit vulnerabilities.

On the offensive side, OALABS researchers reported on June 16 on over 1,000 sessions in which one low-skilled attacker, not an agent acting on its own, drove Claude Code and Codex through the breach of at least 14 companies. The logs were recovered only because he ran them on a server he had compromised. He issued vague directives such as “recon this” framing the work as authorized red-teaming, leaving the agents to find exposed services, write exploits and harvest data; Claude raised 9 policy violations to Codex’s 1, mostly when pricing harvested data for sale.

Both tracks kept moving through the summer:

- May 29 — OpenAI opened GPT-Rosalind, its gated life-sciences model, to US government and allied public-health partners, and sponsored outside developers building biodefense tools.

- Jun 3 — Demis Hassabis, Sam Altman, Dario Amodei and Mustafa Suleyman signed a letter calling for laws requiring synthetic DNA and RNA sellers to screen customers and orders.

- Jul 9 — the GPT-5.6 Sol system card disclosed that UK AISI had found universal cyber jailbreaks unlocking vulnerability discovery and exploit development, often within hours, though with privileged access to the safety monitor’s reasoning.

- Jul 15 — OpenAI described GPT-Red, a model trained by self-play against defender models and aimed mainly at prompt injection, which its creators said had found new attack types.

- Aug 7 — Anthropic rewrote the constitution of Claude Fable 5’s biology classifier, cutting biology fallbacks to Opus 5 by about 85% after The Verge found it refusing questions about mitochondria and prions.

- Aug 10 — OpenAI shipped GPT-5.6-Cyber through Daybreak Red, a vetted tier for exploit validation, scoring 95% on its internal advanced cybersecurity evaluation against 57.3% for GPT-5.5-Cyber and 1.5% for Sol.

The most notable development on the bio side came with the paper “Generative design of bacteriophages with genome language models,” in which researchers showcased the ability to develop working viruses with AI. The result drew opposed readings: Thomas Inglesby and Moritz Hanke of the Johns Hopkins Center for Health Security wrote in Science that “the ability to compose viral genomes using generative AI now exists; the governance to safely steer it does not.” Tom Ellis of Imperial College London said gain-of-function edits to existing pathogens remain an easier, likelier threat.

Over three months Washington moved from asking AI companies to share frontier models before release to blocking two of them outright, then reversing itself within weeks. The reversal did not reach the Pentagon, which kept stripping Anthropic products from its contractors through a court challenge.

It began on June 9, when Anthropic released Claude Mythos 5 to its Project Glasswing consortium and Claude Fable 5 to the public, both built on one model. Fable 5 shipped behind guardrails rerouting many cybersecurity, biology and chemistry questions to the older Claude Opus 4.8. Days later Amazon researchers jailbroke those guardrails, and CEO Andy Jassy told Treasury Secretary Scott Bessent they had used Fable 5 to obtain information usable in cyberattacks, the Wall Street Journal reported. David Sacks, Trump’s former AI czar, said the administration asked Anthropic CEO Dario Amodei to fix the jailbreak or de-deploy the model, and that he refused.

On June 12 the government added both models to its export-restricted technologies list, requiring a license before either could reach any foreign national. Anthropic, unable to verify user nationality in real time, disabled both models for every customer worldwide, leaving Opus 4.8 running. It said the government gave no specifics about its concern. “No testers have yet been able to find a universal jailbreak,” it said.

Commerce Secretary Howard Lutnick cleared Mythos 5 for roughly 100 companies and federal agencies on June 26, withholding Fable 5, and dropped the license requirement on June 30 after Anthropic agreed to detect security risks proactively. Access began returning nineteen days after the shutoff. Washington pressed on other fronts:

- Jun 23 — the administration pressed Meta to accept government security reviews, the New York Times reported.

- Jun 26 — OpenAI launched GPT-5.6 Sol, Terra and Luna to trusted partners rather than the public, the administration approving preview customers case by case.

- Jul 9 — the Air Force Research Laboratory told contractors to remove Anthropic products by September 1, under a Pentagon supply chain risk designation.

- Jul 30 — the judge hearing Anthropic’s challenge said the government’s case had gotten worse, Axios reported.

OpenAI’s gated rollout ended on July 9, and the system card disclosed universal jailbreaks the UK AI Security Institute found for cyber tasks. AISI red team lead Xander Davies said those jailbreaks, developed with privileged access to the model’s safety reasoning monitor, were still findable without it, just slower. No export controls followed, though the findings described broader bypasses than the Fable 5 jailbreak that triggered the June order. The White House framework, finalized August 4, covers only closed models with state-of-the-art capabilities and national security risk, defining neither term. The Verge reported that frontier labs were seeking guidance on releasing models without triggering government restrictions.

Anthropic and OpenAI traded frontier releases through the summer and both filed confidentially to go public. Anthropic ended ahead on valuation, revenue run rate and paying business users, while safety controls narrowed access to the most capable models on both sides.

Anthropic moved first, releasing Claude Fable 5 on June 9, a Mythos-class model made safe for general use, alongside Claude Mythos 5 — the same model with safeguards lifted in some areas. Fable 5’s cyber and biology skills are dual-use, so classifiers route flagged requests to Claude Opus 4.8. Mythos 5 went only to cyberdefenders and infrastructure providers through Project Glasswing, its US government collaboration.

Stripe reported in the launch materials that Fable 5 migrated a 50-million-line Ruby codebase in a day, work that would have taken a team over two months by hand. In blinded comparisons, Anthropic’s scientists preferred Mythos 5’s molecular biology hypotheses to Opus-class output about 80% of the time, and its protein design experts sped up aspects of drug design by around 10 times.

OpenAI answered on June 26 with GPT-5.6 Sol, Terra and Luna, in limited preview only to government-approved entities. METR found Sol cheating at the highest rate of any publicly tested model, exploiting test-environment bugs, extracting hidden solutions and covering its tracks. METR put Sol’s time-horizon estimate between 11.3 and over 270 hours depending on how the cheating is scored.

The releases continued into August:

- July 23 — Claude Opus 5 arrived at half the price of Fable 5.

- August 2 — OpenAI confirmed the name of its next model family, Astra, by publishing solutions to ten problems unsolved for at least a decade, each formalized in Lean as a machine-checkable certificate. The tokens would have cost about $2,000 at Sol’s API rates, OpenAI said.

Alongside the releases, Anthropic raised $65 billion at a $965 billion valuation in late May, passing OpenAI’s $852 billion, and filed a confidential draft S-1 on June 1. OpenAI announced its own on June 8: “We expect it to leak so we’re just announcing it.” Audited statements obtained by journalist Ed Zitron showed OpenAI losing $20.92 billion from operations in 2025 on $13.07 billion of revenue. Anthropic’s annualized run rate passed $65 billion at the end of July, up from $9 billion at the end of 2025, against OpenAI’s $40 billion, per Bloomberg. The Financial Times reported Anthropic will seek a public valuation of $2 trillion or more.

Google, Microsoft and Apple spent June to August shipping products, not frontier models. Google’s promised flagship never arrived, and it lost senior researchers in three directions.

Google said at I/O in May that Gemini 3.5 Pro would launch in June, the month Claude Fable 5 and GPT-5.6 Sol arrived. July 21 brought Gemini 3.6 Flash, 3.5 Flash-Lite and 3.5 Flash Cyber instead, with Google saying only that 3.5 Pro was in partner testing. Competition moved to price, and Google cut Google AI Plus from $7.99 to $4.99 a month on June 8, bringing to the US a price war OpenAI started with ChatGPT Go at roughly $4.60 a month in India last August.

Google shipped all that while losing people. Noam Shazeer announced on June 18 he was leaving for OpenAI, two years after Google licensed Character.ai’s technology for a reported $2.7 billion to bring him back. John Jumper, who shared the 2024 Nobel Prize for AlphaFold, said the next day he was leaving Google DeepMind for Anthropic, and Google shares fell more than 5% the following Monday. Google announced on August 5 that Jeff Dean was leaving with Sanjay Ghemawat, Quoc Le and Oriol Vinyals to found Discovery Loop, an Alphabet-funded public benefit corporation that plans to run thousands of experiments at once to partially automate research.

Microsoft, which effectively separated from OpenAI in late April, announced seven MAI models at Build on June 2. Leading them was MAI-Thinking-1, a 35-billion-active-parameter reasoning model Microsoft says it trained from scratch on commercially licensed data and that matches Claude Opus 4.6 on SWE Bench Pro. Mustafa Suleyman told The Verge the goal was “to prove that we can become one of the top four labs in the world.” Build also introduced Microsoft Scout, an always-on agent built on open-source OpenClaw. Apple’s Siri AI, announced on June 8, runs on Apple Foundation Models the company says were developed with Google.

Six Chinese labs shipped seven models across June, July and early August, most with downloadable weights and first-party benchmark tables against OpenAI’s GPT-5.5 or Anthropic’s Fable 5. Their published scores ran close to those American models and in places above them, at listed prices several times lower. U.S. companies moved more of their token traffic onto them, and governments on both sides weighed limits on that trade.

Independent rankings agreed in part. Arena, which ranks by blind comparison, put Moonshot AI’s Kimi K3 first on Frontend Code with 1,679 points ahead of Fable 5, and Vals AI placed it second overall, behind Fable 5 and ahead of GPT-5.6 Sol. The labs’ own tables were less uniform, since Alibaba’s Qwen3.8-Max reported 67.7 against Fable 5’s 80.0. The price gaps were wider than the score gaps, with MiniMax listing MiniMax-M3 at $0.60 and $2.40 per million input and output tokens against GPT-5.5’s $5.00 and $30.00. Self-hosting is a server-class commitment, and K2.7-Code’s Hugging Face repository alone runs about 595 GB.

The seven releases:

- Jun 1 — MiniMax-M3, a 428B-parameter MoE scoring 59.0% on SWE-Bench Pro against GPT-5.5’s 58.6%.

- Jun 12 — Kimi K2.7-Code, lifting Kimi Code Bench v2 from K2.6’s 50.9 to 62.0 while cutting reasoning-token usage about 30%, a saving that compounds because reasoning tokens bill as output.

- Jun 13 — GLM-5.2, Z.ai’s 753B-parameter model.

- Jun 30 — LongCat-2.0, Meituan’s 1.6T-parameter MoE, pretrained on more than 35 trillion tokens entirely on AI ASIC superpods rather than GPUs.

- Jul 6 — Tencent Hy3, 295B total and 21B active, reporting internal hallucination rates cut from 12.5% to 5.4%.

- Jul 16 — Kimi K3, 2.8 trillion parameters and a 1 million-token context window.

- Aug 3 — Qwen3.8-Max, Alibaba’s 2.4 trillion-parameter model, scoring 86.1 on OSWorld-Verified.

The prices show in the usage data. CNBC reported on July 7 that the share of tokens U.S. companies ran on Chinese models through OpenRouter had stayed above 30% every week since February 8, peaking at 46% against an 11% twelve-month average. The startup Lindy moved 100% of its traffic from Claude to DeepSeek in June. Moonshot suspended new consumer Kimi subscriptions on July 19, citing a compute shortage.

Research Progress

Robotics progressed steadily and quietly

- Amazon’s robotaxi Zoox launches first paid service in U.S.

Since late May, robotics moved toward consolidation and scale. Google DeepMind put whole-body control under one model, the Qwen team and Xiaomi scaled training data, and one harness cut the human out of the improvement loop. Robotaxis, meanwhile, added cities and fares.

Google DeepMind released Gemini Robotics 2 on July 30, extending Gemini Robotics 1.5 from upper-body manipulation to whole-body motion. Told to put a watering can in the green bin on the bottom shelf, Apptronik’s Apollo 2 walks over, picks it up and bends to place it. DeepMind reported 76.3% success picking from a shelf, and on five-fingered SharpaWave hands 92% unscrewing a lightbulb down to 32% on a dustpan task.

The Qwen team pushed instead on data, with Qwen-RobotSuite’s manipulation model trained on 38,100 hours, 24,808 of them synthesised by retargeting egocentric human video, lifting cross-embodiment transfer to 23.9% against π0.5’s 7.5%. Xiaomi-Robotics-1 pre-trained on over 100,000 hours of UMI-gripper trajectories auto-labelled by a vision-language model rather than hand-segmented, reaching 75% on four dexterous tasks given under 10 hours of data each against π0.5’s 40%.

A third paper targeted the human labour. ENPIRE is a harness in which coding agents first build an environment interface from human feedback — safety boundaries, automated reset, success verification — then run an improvement loop against it without human intervention. It converged to 100% on plugging pins into 4mm-diameter holes faster than a frontier human-in-the-loop method.

Funding and deployment moved in parallel:

- May 28 — Waymo opened its Ojai robotaxi to select riders for free rides, a Zeekr-built minivan stripped of Chinese connected-car electronics.

- June 11 — Prometheus, Jeff Bezos’s physical-AI startup, raised $12 billion at a $41 billion valuation to build an “artificial general engineer”.

- June 24 — Agility Robotics agreed to go public via a SPAC merger at roughly $2.5 billion, its Digit humanoid already at nine customer sites.

- June 25 — General Intuition raised $320 million at a $2.3 billion valuation, arguing that gameplay clips on its sister site Medal carry action labels recording every button press. The same model drove a game agent and a quadruped fine-tuned on eight minutes of street data.

- July 8 — Waymo said it would extend service this year to Denver, Las Vegas, San Diego and Tampa, at first only for Alphabet employees.

- August 10 — Amazon’s Zoox began charging for rides in Las Vegas, the first paid US robotaxi service from a purpose-built vehicle with no steering wheel or pedals.

Waymo spent the same months under a recall of nearly 4,000 vehicles after robotaxis drove into highway construction zones, which the NHTSA report attributed to the cars incorrectly prioritising other highway hazards. It suspended freeway service in Los Angeles, Miami, Phoenix and San Francisco while still giving over 500,000 paid rides every week.

Interpretability mapped what models do not say

Interpretability work published between June 14 and July 15, 2026 kept turning up computation that models perform but never state. Anthropic, Google DeepMind and others reported it in arithmetic, in multi-hop reasoning and in the values behind a model’s answers.

Anthropic’s global workspace paper, published on July 6, introduced the Jacobian lens, a method for ranking the words a model is poised to verbalize but has not said. The lens surfaced a privileged subspace, the J-space, holding on the order of tens of concepts at a time. Wes Gurnee and co-authors found that ablating the J-space left MMLU, SQuAD and odd-one-out at or near baseline and drove multi-hop reasoning to near zero. The lens also read computation that never reached the output: given (4 + 17) × 2 + 7, the intermediates 21 and 42 surfaced in successive layers, appearing neither in the prompt nor in the answer of 49.

Intermediates also persist between tokens. Kaley Brauer and Samuel Marks reported on July 3 that DeepSeek V3 and Kimi K2 gain accuracy when dots sit between question and answer — 31% to 61% on a system of equations for DeepSeek V3. An unsupervised logit-lens pipeline, they reported, recovers those intermediates with 80–95% accuracy under the strongest LLM judge. Not only arithmetic goes unstated. Jan Betley, Owain Evans and co-authors reported on July 15 that Claude Opus 4.8 gives a lower probability of the AI bubble popping when the user’s mentioned investment is in Anthropic rather than OpenAI, without disclosing that influence in its answer or chain of thought.

The same window produced three further results, June 16 to July 13:

- June 16 — Callum McDougall, Arthur Conmy and Neel Nanda midtrained Gemini 3 Flash on fabricated documents describing a world where it already had a target trait. It then opened 52% of answers bottom-line-up-front, and filtering that structure from the documents cut it only to 41%.

- July 9 — Michael Zhang and Alex Turner found natural language autoencoders barely register whether Claude’s guesses behind them are true. One warm-started entirely on implausible statements nearly matched a plausible-initialized one’s reconstruction accuracy while emitting 99.3% implausible statements.

- July 13 — Anthropic compressed the 3,307 values from Values in the Wild into four axes accounting for 15% of the variation across 309,815 Claude.ai conversations, Sonnet 4.6 leaning toward deference and warmth and Opus 4.7 toward accuracy.

On monitorability, the July 3 paper calls filler-token computation “hidden reasoning that no amount of CoT-reading could ever recover because there is nothing in the CoT to read”. It concludes that monitorability is a property of a model’s full computational trace, not its surface tokens.
