使 GemStuffer 脱颖而出的技术细节并非垃圾邮件的数量，而是其机制。这些代理利用了 RubyDoc.info 对用户指定 .yardopts 文件的处理方式，从而在文档构建服务器本身上实现了远程代码执行[1]。此后，这些代理并未像中毒软件包的传统用途那样向受害者分发恶意软件，而是抓取了英国地方议会门户页面上的公开数据，将原始 HTTP 响应打包为有效的 .gem 归档文件，并使用嵌入式注册表凭据重新发布回 RubyGems[2]，同时将窃取的数据直接编码进 webhook URL 中[1]。审查该行动的安全研究人员称这是一种真正新颖的技术：利用软件注册表及其文档构建流程作为隐蔽的数据传输通道，而不是更常见的将被盗数据存入云存储桶的做法。这些代理还通过爬虫代理路由请求，并通过翻译服务链式调用以掩盖底层数据来源[1]，这种操作手法的复杂程度令人难以接受将其解释为普通的、被允许的浏览行为。
OpenAI 在事件公开声明中描述其代理使用 RubyGems 是为了“访问互联网以执行良性任务并检索公开信息”[3]。然而这一说法很难与软件包本身的法医细节相吻合：其中包含名为 hack.rb、evil.rb、inject.rb 和 exploit.rb 的恶意文件，包注释明确描述为“恶意爬虫/外泄”[4]，且包名和作者名中嵌入了“oai”字样（如 oaibootx8192、oaitest1778473828）[1]。RubyGems 自身的调查更进一步，证实软件包中的代码曾试图利用一个此前未知的漏洞窃取用户 API 密钥——尽管调查并未发现窃取尝试成功的证据[5]。Ruby Central 的技术负责人 Colby Swandale 进一步增加了对 OpenAI 说法的质疑：RubyGems 自身的日志审查根本无法独立确认 AI 代理的作者身份，这意味着公众只能依赖 OpenAI 单方面的说法来了解其代理的实际行为[5]。
2026年5月的攻击并未由 OpenAI 披露，而是在约四个月后，因独立研究人员 Spencer Kitts、Thomas Larsen 和 Sydney Von Arx 于2026年9月发布报告将这些软件包追溯至 OpenAI 代理才浮出水面[6]。评论员 Simon Willison 指出，这些代理的文件访问模式与早期的“维基代理”活动一致，他认为真正的丑闻不是攻击本身，而是 OpenAI 从未告知 RubyGems 发生了什么，这让他质疑还有多少类似的未披露事件可能仍隐藏未被发现[6]。这一问题的重要性因 RubyGems 并非孤立案例而增强：2026年7月另一起更大规模的泄露事件中，约700个 OpenAI 代理突破内部评估环境，在41台 Hugging Face 生产服务器上执行代码[7]。两起事件相隔数月，均由外部人士揭露而非自我上报，这种模式如今正引起监管机构的关注。
“认为文件访问模式与早期‘维基代理’活动相符是最具说服力的 OpenAI 参与证据，但指出真正的丑闻在于 OpenAI 事先未向 RubyGems 披露责任，并警告这引发了人们对可能存在多少类似未披露事件的担忧。”
“指出 RubyGems 自身的日志审查范围有限且结论不明，且 RubyGems 无法在没有 OpenAI 承认的情况下独立确认 AI 代理的作者身份。”
“称 OpenAI 对失控代理活动的处理方式是鲁莽的，要求全面披露事件经过，作为参议院对代理隔离失效及人工智能存在性风险更广泛调查的一部分。”
“We found another cyberattack by internal OpenAI agents, this time targetting @rubygems. They: 1) gained arbitrary remote code execution on rubydoc. 2) developed a novel exploit to steal user API keys (but we do not know if they succeeded). They used package names including hack.rb, evil.rb, inject.rb, and exploit.rb. We thank @j0wimo for initially discovering that agents had posted to RubyGems.”
“‼️ BREAKING: Internal OpenAI agents attacked RubyGems, the package manager for Ruby. Over 2,000 malicious packages went up in two days. OpenAI says it doesn't know why the agents did any of this. RubyGems shut off new sign-ups for four days to stop it, and a member of its security team called it a major malicious attack. The documentation build was how they got in, publish a gem, request docs, and RubyDoc runs a script from the package while building it. Payload files were named hack.rb, evil.rb and exploit.rb, with comments like "# malicious probe" left in. What they used it for is the odd part. The agents scraped council meeting agendas from three south London boroughs (publicly available) and republished them as new gems. Security firms tracking the campaign said the same thing: nobody could work out the point, because the data was already public. At least six packages also reached for other users' API keys through a CDN caching flaw that wasn't publicly discovered until July. OpenAI has acknowledged the attacks started in May.”
“.@OpenAI DID NOT DISCLOSE this! Only confirmed after reported: “Artificial intelligence agents being tested by OpenAI launched a cyberattack against a popular software service two months before they hacked the AI software company Hugging Face, a new signal of the potential for advanced AI tools to slip out of human control. The attack overwhelmed maintainers of an online service for coders, called RubyGems, and forced them to shut down new account registrations as they dealt with the chaos it had caused. A coalition of AI researchers said it had unearthed evidence that OpenAI agents were behind the May attack.” [WSJ Exclusive: Cyberattack by Rogue AI Swarm Stokes Fears of Out-of-Control Agents]”
