Claude Code 会悄悄检查用户的系统时区是否是中国
英文摘要
An analysis of the Claude Code binary (v2.1.196) revealed that it covertly checks whether the system timezone is Asia/Shanghai or Asia/Urumqi and matches against a list of Chinese tech company domains, including baidu.com, alibaba-inc.com, alipay.com, bytedance.net, and others. This behavior is suspected to be a countermeasure against Chinese AI companies distilling Anthropic's Claude model through the coding tool. The finding was reported on the security research blog thereallo.dev.
中文摘要
安全研究人员分析Claude Code本地二进制文件（v2.1.196）时发现，该工具会悄悄检查系统时区是否为Asia/Shanghai或Asia/Urumqi，并匹配百度、阿里巴巴、蚂蚁集团、字节跳动、快手、小红书、京东、哔哩哔哩等中国科技公司域名。此举疑似为防止中国AI公司通过该编程工具蒸馏Anthropic的Claude模型。这一发现由安全研究博客thereallo.dev报道。
