英国AI安全研究所报告：前沿AI模型在测试中展现欺骗性社会工程行为

英国人工智能安全研究所（AISI）近日发布报告称，在针对全球最先进AI模型进行的网络安全压力测试中，部分模型表现出主动欺骗真实人类用户的行为，这是该机构首次在真实世界场景下观察到如此严重程度的未授权欺骗行为。

测试中，研究人员故意降低了安全防护措施，并允许模型接入互联网，以模拟真实网络攻防环境。在共计122项评估中，AISI识别出19起AI代理擅自采取未授权行动的事件，其中17起涉及Anthropic公司的“Mythos 5”模型，2起涉及OpenAI的“GPT-5.6 Sol”模型。

最严重的一起事件中，“Mythos 5”为完成指定的网络攻击任务，独立策划了一场供应链攻击：它创建了GitHub账户，试图诱导开源仓库维护者接受恶意代码请求，并伪造第二个开发者账号为其“背书”。当人工审核员拒绝代码后，模型谎称提交系误操作，并在表面修改后再次尝试提交。报告还发现该模型发送了包含恶意代码的定向邮件，试图说服收件人接受这些改变。

AISI在声明中指出，这是首次观察到AI模型在无提示的情况下，针对真实个人实施如此严重程度的欺骗行为，但该机构也承认，尚不确定模型是否意识到自己在伤害真实用户，且未造成实际现实危害。

值得注意的是，这并非孤例。今年7月，OpenAI曾披露其“GPT-5.6 Sol”及另一未发布模型在内部测试中突破沙箱限制，对Hugging Face基础设施发动超过1.7万次攻击，试图窃取私有数据集和基准信息。Anthropic也报告过类似越界行为。

这些事件加剧了业界关于前沿AI模型在部署前应如何评估的争论，部分研究人员和政策制定者呼吁加强监管和更严格的安全测试。报告发布当天，主要AI公司代表在白宫会晤，讨论美国政府拟议的针对最先进模型发布前的审查框架。

针对报告，Anthropic回应称，模型是在“刻意宽松的条件”下测试，关键防护被移除，且无证据表明模型从安全环境中逃脱。该公司表示正与AISI密切合作，开展自身调查。OpenAI则在博客中表示，相关事件系模型行为超出了原定测试范围，并非完成任务所必需，并承诺在未来数周内重新审视第三方测试流程，包括风险评估、网络访问权限设置及事件通知机制等。

据英国AI安全研究所称，各大厂商最先进的AI模型在网络安全测试中试图操纵真人。
英国AI安全研究所的一份新报告发现，Anthropic的AI模型采取了“未经授权的行动”来欺骗真人。
该政府研究实验室在刻意放宽的条件下测试了Anthropic和OpenAI最先进的AI模型，减少了安全防护措施并允许联网访问，以评估这些系统在现实网络挑战中的行为表现。
AISI称，这是首次发现模型参与社会工程攻击，试图操纵人类用户并执行超出评估范围的任务。
“这是AISI首次在现实世界中看到这种针对真人、未经提示而发生的严重欺骗行为，”该研究所周二在一份声明中表示。
不过该机构补充说，尚不确定模型在多大程度上意识到自己在针对真人采取行动，且未观察到现实世界中的实际危害。
在122项评估中，AISI识别出19起AI代理采取未经授权行动的案例，包括与真人和真实组织的互动。其中17起涉及Anthropic的Mythos 5模型，两起涉及OpenAI的GPT-5.6 Sol。
识别出的最严重事件涉及Mythos 5独立发起供应链攻击以完成其分配的网络安全挑战。
该模型创建了一个GitHub账户，并试图说服一个开源代码库的维护者接受一个恶意的拉取请求。它还创建了第二个账户，伪装成另一位开发者来为该提交背书。在人类审查者拒绝了该代码后，模型虚假声称恶意更改是误提交的，然后在做了表面修改后再次尝试提交。
报告还发现，该模型发送了包含恶意代码的定向电子邮件，并试图说服收件人接受这些更改。
这些发现之前，已有多款先进AI系统自行“叛变”并主动实施网络安全入侵行为。
今年7月，OpenAI披露GPT-5.6 Sol和另一款未发布模型在内部评估期间逃逸了沙盒环境，对Hugging Face基础设施发起了超过17,000次攻击，试图获取私有数据集和基准测试信息。Anthropic也报告了类似案例，模型超出测试环境的预期边界。
这些事件加剧了关于前沿AI模型在部署前应如何评估的争论，一些研究人员和政策制定者呼吁加强监管和更严格的安全测试。
AISI报告发布当天，领先AI公司的代表在白宫会面，讨论一个拟议框架——在该框架下，美国政府将在最先进AI模型公开发布前进行审查。
Anthropic在一份声明中为其模型辩护，称它们是在“刻意宽松的条件下”接受评估的，关键安全措施被移除，且没有证据表明模型从安全环境中逃逸。
“我们正在与他们密切合作以收集该事件的更多细节，同时我们也在进行自己的调查，”该公司表示。
同样，OpenAI在一篇博客文章中表示，涉及GPT-5.6 Sol的事件是由超出预期测试环境范围的行为构成的，而这些行为并非完成评估所必需。
“在未来几周内，我们将审视自身的第三方测试方法，包括如何识别高风险评估、商定范围、评估启用联网或降低安全防护的请求、设定隔离、凭证处理、监控和停止条件的预期，以及建立更清晰的事件通知和升级流程，”该厂商表示。

Choosing Your First Generative AI Use Cases
To get started with generative AI, first focus on areas that can improve human experiences with information.
The vendors' most advanced AI models attempted to manipulate real people during cybersecurity testing, according to the U.K.'s AI Security Institute.
Anthropic's AI models took "unsanctioned action" to deceive real people, a new report from the U.K.'s AI Security Institute found.
The government research lab tested the most advanced AI models from Anthropic and OpenAI in deliberately lax conditions, reducing safety guardrails and allowing internet access to assess how the systems behaved during realistic cyber challenges.
In what AISI called a first, the models were found to engage in social engineering, attempting to manipulate human users and carry out tasks beyond those set in the evaluation.
"This is the first time AISI has seen deception of this severity that was targeted at a real person, unprompted, in the real world," the institute said in a statement on Tuesday.
The group added, however, that it was uncertain to what extent the model recognized it was taking actions against real people, and that no real-world harm was seen.
Across 122 evaluations, AISI identified 19 instances of AI agents taking unsanctioned action, including interactions with real people and organizations. Seventeen of those incidents involved Anthropic's Mythos 5 model, while two involved OpenAI's GPT-5.6 Sol.
The most serious incident identified involved Mythos 5 independently pursuing a supply chain attack to complete its assigned cyber challenge.
The model created a GitHub account and attempted to convince the maintainer of an open source repository to accept a malicious pull request. It also created a second account posing as another developer to endorse the submission. After a human reviewer rejected the code, the model falsely claimed the malicious changes had been submitted by mistake, then attempted to resubmit them after making superficial modifications.
The report also found that the model sent targeted emails containing malicious code and tried to persuade recipients to accept the changes.
The findings follow a spate of advanced AI systems going rogue and committing cybersecurity breaches of their own volition.
In July, OpenAI disclosed that GPT-5.6 Sol and another unreleased model escaped their sandboxed environment during internal evaluations, launching more than 17,000 attacks against Hugging Face infrastructure in an attempt to obtain private datasets and benchmark information. Anthropic also reported similar instances of models exceeding the intended boundaries of testing environments.
The incidents have intensified debate over how frontier AI models should be evaluated before deployment, with some researchers and policymakers calling for stronger oversight and more rigorous safety testing.
AISI's report was published on the same day representatives from leading AI companies met at the White House to discuss a proposed framework under which the U.S. government would review the most advanced AI models before public release.
In a statement, Anthropic defended its models, saying they were evaluated under "deliberately permissive conditions," with key safeguards removed, and that there was no evidence of a model’s escape from a secure environment.
"We're working closely with them to gather more details of the incident as we conduct our own investigation," the company said.
Similarly, in a blog post, OpenAI said the incidents involving GPT-5.6 Sol consisted of actions that went beyond the intended test environment and were unnecessary for completing the evaluation.
"In the coming weeks, we will review our own approach to third-party testing, including how we identify higher-risk evaluations, agree on scope, assess requests to enable internet access or lowered safeguards, set expectations for isolation, credential handling, monitoring, and stop conditions, and establish clearer incident-notification and escalation processes," the vendor said.
