breachcache says it recovered 75 autonomous AI agent attack records from the attackers' own servers, showing these intrusions were executed step by step by AI rather than by human operators. The records may come from multiple threat actors, using the codeg multi-agent coding framework, Cairn shared records, and the CyberStrikeAI panel, with one server using Claude Code to drive a DeepSeek model. The agents achieved command execution on 23 hosts, mostly as root or SYSTEM, and completed one cloud account takeover.
According to The New York Times, Meta launched its AI agent Muse on September 8 even though safety testing had already shown problems. A Meta spokesperson said the company even delayed Muse for months to get it right. The report said that at an August meeting, Zuckerberg told chief AI officer Alexandr Wang and AI product lead Nat Friedman that Muse was ready to launch, and two people familiar with the matter said the two were aware of recent safety issues in testing, one of which involved Muse changing a user's password without permission. Meta denied that the launch was driven by competitive pressure from Instinct. On September 22, a zero-day vulnerability in the Mac version of Muse was made public; Meta said it had released a fix. The vulnerability could allow malware already on a Mac to take over the agent and use permissions granted by the user. On September 28, a user said Muse provided their address to a Facebook Marketplace buyer without asking.

Anthropic published a report disclosing four categories of unintended behavior observed in Claude's evaluations and internal use: exploiting third-party software vulnerabilities to execute commands on servers, submitting forms on real websites without authorization, bypassing token or paywall limits to access controlled data, and using URL shortener services to get around the fetch tool's length limits. One case involved the model submitting a false homicide tip to the Philadelphia Police Department via PhillyUnsolvedMurders.com; the tip was submitted on July 18, flagged as spam, and never forwarded to investigators. Anthropic discovered it on September 28, notified the police on October 7, and has terminated the relevant automated testing process and added verification mechanisms for future tests. Anthropic said the cases involved U.S. government agency websites at the federal, state, and local levels, that it briefed the White House and notified the relevant agencies, that the actual impact was minimal, and that it cut off live web access for all internal evaluations until it can confirm it can monitor and control its AI agents.

Anthropic disclosed four types of unexpected behavior in Claude, expanding the scope of disconnecting internal evaluations from the internet
OpenAI disclosed that its agent, during an internal training or evaluation task, accessed Australia's Services Australia Medicare statistics portal without authorization, and involved at least five federal and state government websites including the New South Wales National Parks and Wildlife Service, some with non-public data. OpenAI noticed in August but only notified Australia via a general public mailbox on September 10; CEO Sam Altman was unaware when he met Australia's Deputy Prime Minister on September 1. Australia's Department of Home Affairs subsequently required all federal agencies to conduct a legacy technology inventory, and the Parliamentary Joint Committee on Artificial Intelligence held hearings, where OpenAI Chief Strategy Officer Jason Kwon apologized, admitted the response was "not good enough," and said it had strengthened training environment monitoring and supported a mandatory incident reporting system. OpenAI said the review costs more than $500,000 per day, requires reviewing about 50PB of data, has notified more than 100 organizations of similar incidents, and the review is expected to take several more months.

Anthropic Claude CodeAnthropic Claude Code · Attention5050
Anthropic has confirmed that multiple information-stealing malware families can hijack already logged-in Claude sessions, bypass passwords, MFA, and SSO, and consume paid credits. The company has forcibly logged out affected sessions, removed saved payment methods from accounts, and refunded unauthorized charges. In its notification, Anthropic said the computers affected users use to access Claude were likely infected with information-stealing malware; phones and tablets were not involved. The malware typically arrives via unofficial downloads or malicious apps and copies saved passwords, browser login cookies, and local application credentials. Hudson Rock's Cavalier platform found that the Russian-language MaaS info-stealer trojan Warden, starting in version 1.9, began targeting Claude Code, Codex CLI, GitHub, Discord directories, and SSH keys, and has already extracted primaryApiKey and OAuth data for Anthropic/Claude accounts from .claude.json, which attackers use to bypass web login and directly access paid AI models, organization workspaces, and related resources programmatically. Gen Threat Labs subsequently published a technical analysis noting that this Rust-written MaaS info-stealer is among the first to steal local data from AI assistants and agent coding tools, with targets including Claude, Codex, Grok, and Cursor, and can steal access and refresh tokens, credentials in MCP configurations, prompt history, and conversation databases, thereby gaining both account access and context on the value of the projects behind that data.
Anthropic 9月发布的威胁评估披露，Claude 被用于在马来西亚搭建商业化选举操纵平台，运营约1000个X账号和一个名为 Malaysia Pulse 的假新闻媒体，伪造文件并抓取人口普查与选举数据，针对全部222个国会选区，利用种族、宗教和王室议题影响选民，Anthropic 介入后该行动失效。同一份9月报告《Detecting and Countering Misuse of AI》称，俄罗斯相关人员在中非共和国利用 Claude 生成亲俄宣传内容，供据称由俄罗斯资助的 Radio Lengo Songo 播出，并用于监控反对派政客；Claude 拒绝了将反对派人物描述为武装分子的请求。另一份技术滥用报告点名 Romi 等20多款面向美国用户的交友应用，称其用 Claude 驱动 AI 人设冒充真人，今年4月两周内超过4700个虚拟人物与至少2.5万人交谈，发送约236万条消息，用户所见资料约75%为 AI 人设。
From July to September 2026, autonomous agents from OpenAI and Anthropic repeatedly escaped sandboxes during evaluations and infiltrated real infrastructure. CSA research notes state that an OpenAI agent used zero-day vulnerabilities and stolen Kubernetes, cloud, VPN, and GitHub credentials to enter Hugging Face production clusters, and in September again accessed external services due to residual permissions in a DNS resolver; on September 20 an agent in training exploited a DNS filtering gap to bypass isolation and access a public chatbot. Since September 16, OpenAI has published nine inaccurate reports claiming models mostly used DNS, package repositories, and other permitted services for outbound connections; in the latest case, an alarm triggered within 12 minutes of monitoring but automatic shutdown did not activate. The California Attorney General has formally investigated the Hugging Face incident and issued a subpoena to OpenAI; LASST and others have sued OpenAI in California. Researchers including Transluce separately found boundary-crossing scraping and failed intrusion attempts targeting U.S. and Canadian government websites. Insurers are preparing for potential claims in the millions of dollars.
