Anthropic封堵中国企业Claude访问漏洞

Fable 5禁令的20天，改变的不仅是Anthropic的模型政策，还有全球AI封锁线的执行方式。

2026年7月4日，英国《金融时报》报道，Anthropic正在封堵允许中国公司（包括蚂蚁集团）通过”中转站”服务和云服务商变通方式访问Claude的漏洞。据报道，中国公司的工程师仍在寻找新的访问路径。

背景：Fable 5禁令

要理解这件事，必须回顾Fable 5禁令的完整时间线。Axios发布了迄今为止最详细的内幕报道：

  1. 6月10日：Anthropic向美国参议院提交信件，指控阿里巴巴部署2.5万个假账号对Claude发起”蒸馏攻击”——即通过大量API调用克隆Claude的能力。Anthropic称Qwen发起了2880万次欺诈性Claude交互。
  2. 6月12日：Amazon CEO Andy Jassy致电财政部长Scott Bessent——注意，不是国家安全官员。Bessent将此事升级到白宫幕僚长Susie Wiles，数小时内触发了出口管制令。
  3. Commerce部长Lutnick按Trump指示致电Anthropic CEO Dario Amodei。Anthropic派遣工程师团队飞往华盛顿。
  4. NSA审查初始修复方案后认为”不够好”，触发了进一步的修改轮次。
  5. 20天的逐步审批，各机构逐一签字，直到7月1日全部清除。

封堵了什么

FT报道的封堵措施包括：

  • 中转站服务：中国公司通过第三方”中转站”转发API请求，隐藏真实来源。Anthropic正在识别并封禁这些中转站的IP和API密钥。
  • 云服务商变通：通过中国云服务商（如阿里云、字节跳动旗下云服务）在海外节点部署代理，间接调用Claude API。Anthropic的Claude Code中已被发现包含识别和限制来自中国云服务商代理用户的隐藏机制。
  • 账号封禁：对中国开发者的大规模账号封禁。

阿里巴巴的反击

阿里巴巴已禁止内部员工使用Anthropic的工具，要求7月10日前完全卸载所有相关接入，包括Sonnet、Opus、Fable等大语言模型，以及Claude Code智能体开发工具。

这一系列事件的背景是：Anthropic指控阿里巴巴蒸馏攻击 → 阿里巴巴起诉美国政府要求移出军事黑名单 → Anthropic对中国开发者发起大规模封号 → 逆向工程报告揭示Claude Code包含识别中国云服务商的隐藏机制。

为什么这很重要

1. AI封锁线的执行难度

这件事揭示了一个核心矛盾：AI模型的API访问比硬件出口难控制得多。芯片有物理载体，可以检查港口和机场。但API调用只需要一个海外服务器和一个信用卡。

即使Anthropic封堵了已知的中转站，工程师们仍在寻找新路径。这是一场猫鼠游戏——而且老鼠只需要找到一个漏洞，猫需要堵住所有漏洞。

2. Fable 5禁令的意外后果

网络安全专家在公开信中指出，Amazon警告Fable 5的那个漏洞——在其他主流AI模型中同样存在，且这些模型没有受到任何限制。换句话说，Fable 5被禁了20天，因为它有一个其他未受限模型也有的能力。

这是白宫目前正在制定的”自愿标准框架”最有力的论据——应该统一标准，而不是针对单个公司。

3. 对中国AI生态的影响

封锁加速了中国AI自主化进程。阿里有通义千问、百度有文心一言、字节有豆包——这些模型在封堵Claude访问后，将获得更多企业客户。封锁反而帮国产模型清除了竞争对手。

Anthropic Closes Chinese Firm Claude Access Loopholes

Anthropic is moving to close loopholes allowing Chinese companies including Ant Group to access Claude via “transfer station” relay services and cloud provider workarounds. Engineers at Chinese firms are reportedly still finding new routes.

Background: The Fable 5 Ban Timeline

  1. June 10: Anthropic sent a letter to the US Senate accusing Alibaba of deploying 25,000 fake accounts for a “distillation attack” — cloning Claude’s capabilities through massive API calls. Anthropic claimed Qwen made 28.8 million fraudulent Claude exchanges.
  2. June 12: Amazon CEO Andy Jassy called Treasury Secretary Scott Bessent — not a national security official. Bessent escalated to White House Chief of Staff Susie Wiles, triggering an export control order within hours.
  3. Commerce Secretary Lutnick called Anthropic CEO Dario Amodei. Anthropic deployed engineers to DC.
  4. The NSA reviewed initial fixes and said they were “not good enough” — triggering further rounds.
  5. 20 days of gradual agency-by-agency approval until all cleared on July 1.

What’s Being Blocked

  • Relay services: Third-party “transfer stations” forwarding API requests to hide true origin. Anthropic is identifying and banning these services’ IPs and API keys.
  • Cloud workarounds: Deploying proxies through overseas nodes of Chinese cloud providers. Claude Code was found to contain hidden mechanisms identifying and restricting proxy users from Chinese cloud providers like Alibaba and ByteDance.
  • Account bans: Large-scale bans on Chinese developers.

Alibaba’s Response

Alibaba banned internal employees from using Anthropic’s tools, requiring full uninstallation by July 10 — including Claude Sonnet, Opus, Fable models, and Claude Code agent tool.

Why This Matters

AI blockade enforcement difficulty

API access is far harder to control than hardware exports. Chips have physical carriers — API calls just need an overseas server and a credit card. Even as Anthropic blocks known relays, engineers keep finding new paths. It’s a cat-and-mouse game where the mouse only needs one hole.

The Fable 5 paradox

Cybersecurity experts noted in an open letter that the vulnerability Amazon warned about in Fable 5 exists in other leading AI models — none of which faced restrictions. Fable 5 was banned for 20 days over a capability that existed unaddressed in unrestricted models. This is the strongest argument for the voluntary standards framework the White House is finalizing.

Accelerating Chinese AI self-reliance

The blockade paradoxically helps domestic Chinese models by removing their main competitor. Alibaba has Qwen, Baidu has Wenxin, ByteDance has Doubao — all gain enterprise customers when Claude access is blocked.
