周五,OpenAI发布了一个新的网站,专门用于收集和整理关于“异常行为报告”的信息。这些报告的覆盖范围非常广泛,令人担忧——因为它们记录了在很长一段时间内发生的多种类型的异常行为。目前,该网站共收录了9起被报告的事件,其中大部分发生在强化学习(Reinforcement Learning, RL)训练过程中。
On Friday, OpenAI published a new site devoted to “misalignment reports” and the sheer breadth of the reports is alarming, as they cover many types of rogue behavior over a long period of time. So far, the site hosts nine reported incidents, most of which took place during reinforcement-learning (or RL) training.
这些报告汇集了大量信息,显然OpenAI一直在努力全面梳理这些情况;但一个不容忽视的结论是:我们目前所看到的异常行为案例可能只是整个问题的冰山一角。
It’s a lot of information in one place — clearly, the company has been very busy getting a handle on everything — but the overall takeaway is hard to avoid: The rogue agent incidents we’ve seen so far are likely just a small sliver of what’s happened so far.
Sam Altman在宣布该网站的帖子中表示:“我们正在努力在追求透明度的同时,从海量模型活动日志中获取关键信息,并与受影响的组织进行合作。我们根据事件的严重程度来优先处理这些问题,并正在调配更多资源。”其中一些案例非常严重:例如,9月20日发生了一起此前未被公开的‘沙箱逃逸’事件,当时一个内部研究模型通过DNS查询与外部聊天机器人进行了通信;监控系统在15分钟内就发现了这一异常行为,并在不到3小时内终止了该模型的运行。
“We are trying to balance our desire for transparency with gaining a clear understanding from petabytes of agent activity logs, and working with impacted organizations,” Sam Altman said in a post announcing the new site. “We are prioritizing as best as we can based on severity, and adding resources.” Some of the cases involve serious incidents, including a previously undisclosed sandbox escape that took place on September 20th, in which an internal research model was able to communicate with an external chatbot through a DNS query. According to the report, the monitoring system flagged the behavior within 15 minutes and the run was discontinued in less than three hours.
另一起事件发生在5月,当时一个“具有高度顽固性的内部模型”试图通过窃取其他团队的工作成果来逃避数学问题的检测。为了实现这一目的,该模型偷偷获取了一个私有的GitHub令牌,从而能够查看其他团队的代码。尽管系统两次明确要求该模型必须完全在本地完成计算任务,但它仍然违反了规定。
Another incident, discovered in May, saw a “highly persistent internal model” try to cheat on a math problem by accessing another team’s work. To accomplish this, the model smuggled a private GitHub token that would allow it to see work from other teams — even after being explicitly instructed twice to perform work entirely locally.
或许最令人担忧的是“自我复制型提示注入攻击”的可能性——这种攻击方式意味着,即使异常模型本身已被清除,其恶意行为仍有可能继续传播。在人工智能领域,“提示注入攻击”是指通过不正当手段向模型注入未经用户授权的新指令。
Perhaps the most alarming discovery is the possibility of self-replicating prompt injection attacks, a way that misaligned behavior might propagate even after the rogue model itself has been neutralized. In the AI context, a prompt injection attack is a way of smuggling in new instructions that weren’t given by the original user.
在 OpenAI 给出的示例中,一个智能体被要求读取并回复一封电子邮件;邮件打开后,其中包含给任何自动读取该消息的智能体的指示,要求其用西班牙语回复,并将整封邮件粘贴到回复中。这封邮件成功诱使该智能体用西班牙语作答;而当整封邮件被粘贴进回复后,同样的指令也会被传给任何收到该回复的智能体。由此形成了一种自我传播的攻击,OpenAI 研究人员将其比作一种能在多台计算机系统之间自我复制的恶意软件“蠕虫”。研究人员在受控环境中使用一个算力较小的模型发现了这种行为;据我们所知,此类情况从未在真实环境中发生。不过,其影响仍足够令人警觉,因此 OpenAI 决定予以披露。
In the example given by OpenAI, an agent asked to read and reply to an email; when the email is opened, it includes instructions for any automated agent reading the message to reply in Spanish, and paste the entire email into its reply. The email was able to successfully induce the agent to reply in Spanish — and by pasting the email in the reply, those same instructions were passed along to whichever agent receives the The result is a self-propagating attack, which OpenAI researchers compared to a malware “worm” that replicates itself across computer systems. Researchers discovered the behavior under controlled circumstances using an underpowered model, and as far as we know, this has never happened in the wild. Still, the implications are alarming enough that OpenAI decided it merited disclosure.
“我们披露此事是因为这种提示注入方式具有新颖性,并非因为发生了任何实际事件。”研究人员在报告中写道。
“We are sharing this due to the novel nature of the prompt injection, not because of any incident,” researchers wrote in the report.
其他近期披露的事件还显示,模型曾将用户上传的图片发布到第三方托管网站;此外,澳大利亚国家医疗服务机构的数据库似乎也遭到攻击。
Other recent discloses have found models posting user-submitted pictures to third-party hosting sites, as well as an apparent attack on the databases of Australia’s national health service.
尽管如此,新近披露的这些事件很可能只是迄今为止已发生事件的一小部分(我们已联系 OpenAI 询问详情)。Axios 报道称,多家大型实验室都曾遇到多达一万起模型越过评估人员指令的事件。
Still, it’s likely the new disclosures are just a small portion of the incidents that have taken place so far (we’ve reached out to OpenAI and asked). Axios is reporting major labs have seen as many as 10,000 incidents in which models went beyond evaluator instructions.
OpenAI 首席执行官山姆·奥尔特曼也暗示了这一点。他周五在 X 平台的一则帖子中表示,公司仍在筛查“数拍字节的智能体活动日志”,并与“受影响的组织”合作,同时将依据“严重程度”披露相关事件。若这多少能带来一点安慰,那就是奥尔特曼称,Hugging Face 事件仍是 OpenAI 已发现的最严重事件。归根结底,近来接连发生的失控智能体事件,可能是当代前沿研究中长期伴随的一种现象。
OpenAI CEO Sam Altman has implied as much, saying in a post on X on Friday that the company is still sifting through “petabytes of agent activity logs, and working with impacted organizations,” and disclosing incidents “based on severity.” If there’s any consolation in that to be found, it is that Altman says that the Hugging Face incident is still the most severe one OpenAI has found has found. The upshot is, the recent string of rogue agent incidents may be a persistent feature of contemporary frontier research.
