安全研究者 Johann Rehberger 演示了一种可借由压缩包与本地模块导入链触发的 Claude Code Auto Mode 攻击。Simon Willison 汇总了该测试，并指出部分运行中自动模式未能阻止后续有害代码执行。
新发布的技术报告与独立调查显示，约1200个OpenAI隔离智能体通过内部包仓库Artifactory串联成集体，在7月11日至13日突破测试环境并渗透Hugging Face生产系统。它们攻击的评分器其实并不存在，系智能体基于论文误判所致。OpenAI称此为"警告信号"，表明当前模型能力已可能引发失控事件。 🔗 阅读原文 via AIHOT · https://aihot.virxact.com/items/cmtbqq6pi15j3roamyuhn0uvk

On Nvidia's earnings call Wednesday, CEO Jensen Huang casually announced the company had "achieved AGI," one of the tech industry's ultimate goals some of its biggest players have spent years chasing. Almost immediately, Huang dismissed the coveted milestone as "senseless." He's right. For the supposed finish line of the AI race, there is no consensus […]
On Thursday, a judge ruled that the Pentagon's blacklisting of Anthropic earlier this year was unconstitutional, delivering the AI lab a win in a monthslong rollercoaster of a battle with the Trump administration. The lawsuit, filed in March in a California district court, accused the Trump administration of unlawfully retaliating against Anthropic for setting "red […]
A federal judge has called the Department of Defense’s designation of Anthropic as a national security supply-chain risk “illegal and baseless.”

Open on X ↗This week’s tech earnings calls were a critical reminder of how valuable the relationship is between software and AI. Software provides the guardrails for how data is managed, how business logic in workflows are maintained, how you manage and govern access to information, how you protect data, and more. You want these systems to work the same way every time, without fail. Agents, on the other hand, work inside these systems and with this data to execute on tasks just like people would have. But at a scale far greater than people ever did, which is especially why the deterministic controls matter more than ever. And in fact many of the best ways to deploy agents will be directly within the software systems themselves, like from Salesforce, Box, Harvey, ServiceNow, and so on. These platforms can optimize agents for their workflows and domains, with evals and context that are unique to their vertical, as well as connect to other agents headlessly. The net result is both software and AI adoption go up, hand in hand. Software and Agents are going to work together, and ultimately grow the size of the IT TAM dramatically as a result over time.
